Oxidation is a key problem that reduces the shelf life of fresh and processed meat
and meat products. Antioxidants are added to stabilize free radicals there by delaying
lipid and protein oxidation, retard development of off-flavors, and improve colour
stability. Addition of synthetic antioxidants to combat oxidative damage has the
potential to cause adverse health effects and thus remained a challenge to the meat
industry. In this regard research studies have directed towards natural antioxidants
utilizing fruits, herbs, spices, and vegetable extracts in meat industry for improving the
quality of fresh and processed meat and meat products. Due to their high phenolic
compound content, fruits and other plant materials provide a good alternative to
synthetic antioxidants. This review provides the current overview of the recent advances
on plant materials used as natural antioxidants in meat and meat products.
Keywords: Natural antioxidants, fruits, herbs, spices, lipid oxidation, meat.
Meat as a food has a complex physical structure and chemical composition that is
very susceptible to oxidation (Wood et al., 2008; Rather et al., 2016a). The oxidative
stability of meat depends upon the balance and the interaction between endogenous
anti- and pro-oxidant substances and the composition of substrates prone to oxidation
including poly unsaturated fatty acids (PUFA), cholesterol, proteins and pigments
(Decker and Xu, 1998). The oxidation of lipids in meat products is a key problem that
reduces shelf life of frozen meats, fermented processed meat such as dry sausages, and
cured raw ham. In meat lipids, the formation of lipid oxidation products from unsaturated
fats is initiated by singlet oxygen converted from triplet oxygen or a catalyst and triplet
oxygen. Further reactions yield hydro peroxides that act as strong oxidizing agents (ROS
— reactive oxygen species) (Kubow, 1992). Metal catalysts such as iron and copper are
key elements involved in the breakdown of these compounds. When hydro peroxides
are degraded, highly reactive free radicals are generated that in turn react with the
double bonds of other unsaturated lipid acids thereby producing more radicals that
further propagate the chain reaction of lipid oxidation (Kubow, 1992). In addition lipid
oxidation products initiate the oxidation of proteins leading to serious health concerns,
and undesirable sensory changes and deterioration of nutritive value (Rather et al.,
2015b-c, 2016b). Lipid oxidation can be reduced or inhibited by the use of antioxidants
in meat and meat products and thus the product quality and shelf-life can be improved.
Antioxidants are substances that at low concentrations retard the oxidation of easily Oxidizable bio molecules, such as lipids and proteins in meat products, thus improving shelf life of products by protecting them against deterioration caused by oxidation (Kumar et al., 2015). Antioxidants can prevent lipid Peroxidation using the following mechanisms: preventing chain inhibition by scavenging initiating radicals, breaking chain reaction, decomposing peroxides, decreasing localized oxygen concentrations and binding chain initiating catalysts, such as metal ions (Dorman et al., 2003). There are a huge number of compounds that have been proposed to possess antioxidant activity, but only a few can be used in food products. The use of antioxidants in food products is controlled by regulatory laws of a country or international standards (Karre et al., 2013). In the United States the use of antioxidants is subject to regulation under the Federal Food, Drug and Cosmetic Act, Meat Inspection Act, Poultry Inspection Act, and other state laws (Mikova, 2001; Shahidi and Zhong, 2005). In the European Union, regulation of antioxidants is stipulated by the European Parliament and Council Directive No. 95/2/EC of 20 February 1995 on food additives other than color or sweeteners. Another organization that regulates the use of antioxidants is the Codex Alimentarius, which is a collection of internationally adopted standards. Codex Alimentarius permits only the use of those antioxidants which have been evaluated by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and these may be used only in foods standardized by Codex (Mikova, 2001). Typical synthetic antioxidants such as propyl gallate, butylated hydroxyanisol (BHA), butylated hydroxytoluene (BHT), tertiary butyl hydroquinone (TBHQ), and nitric oxide from sodium nitrite have been widely used in meat and meat products (Weiss et al., 2010). Due to the potential toxicological effects of synthetic antioxidants, the demand for natural antioxidants has increased in the recent years (Shah et al., 2014).
In view of the health effects of synthetic antioxidants consumers demand healthier or "classical" meat products containing natural antioxidants. Recently researchers have focused towards identification of novel antioxidants from plant sources due to their high content of phenolic compounds and provide alternative to currently used conventional antioxidants (Karre et al., 2013). Plant extracts are typically obtained by maceration of plant matter with organic solvents or by supercritical CO2 extraction (Oberdieck, 2004). These natural antioxidants from plants, in the form of extracts, have been obtained from different sources such as fruits (grapes, pomegranate, date, kinnow), vegetables, (broccoli, potato, drumstick, pumpkin, curry, nettle), herbs and spices (tea, rosemary, oregano, cinnamon, sage, thyme, mint, ginger, clove) and investigated to decrease the lipid oxidation (Akarpat et al., 2008; Das et al., 2012; Devatkal et al., 2010; Kanatt et al., 2007; Mansour and Khalil, 2000; McCarthy et al., 2001a,b; Nissen et al., 2004; Rojas and Brewer, 2007, 2008; Shan et al., 2009; Wojciak et al., 2011). In addition to plant extracts direct incorporation of plant materials such as fruit pulp, seed powder have been investigated as potential antioxidants in meat and meat products (Karre et al., 2013).
The objective of this paper is to review the recent published literature on plant based natural antioxidants used in meat and meat products.
Mechanism of action of natural antioxidants
The concept of natural antioxidant refers to any substance that, when present at a lower concentration compared to that of an oxidizable substrate, is able to either delay or inhibit the oxidation of the substrate (Pisoschi and Pop, 2015). The total antioxidant capacity of plant materials such as culinary herbs, spices, vegetables, as well as fruits and oilseed products reflects concentrations of ascorbic acid (vitamin C), alphatocopherol (vitamin E), beta-carotene (vitamin A precursor), various flavonoids, and other phenolic compounds (Velasco and Williams, 2011; Pennington and Fisher, 2009). The different factors which initiate lipid and protein oxidation include the presence of oxygen and transition metal ions, moisture, heat and light. To inhibit or retard the rate of oxidation, oxygen and metal catalysts must be removed or sequestered and food prone to oxidation must be stored at low temperatures and shielded from light (Embuscado, 2015). The natural antioxidants in plant materials have strong H·-donating activity (Muchuweti et al., 2007) or have high radical-absorbance capacity or sequestered metal catalysts to render them un reactive (Kumar et al., 2015). Some natural antioxidants prevent the formation of free radicals and propagation of reactive oxygen species (ROS), while other scavenge free radicals and chelate transition metals (pro oxidants) (Ozsoy et al., 2009). The antioxidant potential of these natural substances depends on their pattern of functional groups on this skeleton (Wojdylo et al., 2007). For example, the number and position of free hydroxyl (–OH) groups on flavonoid skeleton decide the free radicalscavenging potential (Lupea et al., 2008). Presence of multiple –OH groups and ortho-3, 4-dihydroxy structures enhance the antioxidant potential of natural phenolics (Geldof and Engeseth, 2002; Brown and Kelly, 2007). Plant pigments such as anthocyanins and their hydrolyzed products, anthocyanindins also contain –OH groups, which can donate H· and thus have antioxidant potential (Kumar et al., 2015).
Natural antioxidants from fruits and vegetables
The natural antioxidants have been studied in meat from a huge number of plant sources. Some of these natural antioxidants are also available commercially and several studies have been carried out by different researchers applying commercially available natural antioxidants of plant origin to meat (Table 1). The protective effect of fruits has been attributed to phyto chemicals, which are the non-nutrient plant compounds such as the carotenoids, flavonoids, isoflavonoids, and phenolic acids. Phyto chemicals have been found to possess huge functional activities, such as protect against lipid oxidation, inhibit cancer cell proliferation, and regulate inflammatory and immune response (Kumar et al., 2015). Among the phyto chemicals, phenolic compounds were found to play major role in protection against oxidation. The antioxidant potential of various fruits (plum, grape seed extract, pomegranate, and bearberry) has been conducted in meat products.

Numerous studies have investigated the antioxidant properties of plums in variety of meat products. Nunez de Gonzalez et al. (2008a, b) reported the antioxidant activity of plums in precooked pork sausage and roast beef. Raw and cooked pork sausage patties (32% fat) treated with 3% and 6% dried plum puree, 3% and 6% dried plum and apple puree were evaluated for lipid oxidation at 4°C for 28 days or frozen at -20°C for 90 days (Nunez de Gonzalez et al., 2008a). Precooked pork sausage patties treated with 3% and 6% dried plum puree, or 3% and 6% dried plum and apple puree showed a reduction (p < 0.05) in TBARS values compared with the control (untreated) after 28 days of storage at 4°C. Precooked pork sausage patties during frozen storage for 90 days at -20°C treated with 3% and 6% dried plum puree, or 3% and 6% dried plum and apple puree also had a significantly lower TBARS value than the control. In precooked roast beef lipid oxidation was reduced (p < 0.05) when treated with fresh plum juice concentrate, dried plum juice concentrate, and spray-dried plum powder (Nunez de Gonzalez et al. (2008b). Yildiz-Turp and Serdaroglu (2010) found that plum puree (PP) at different concentrations (5%, 10% and 15%) in low fat (5- 6%) beef patties resulted in lower (p < 0.05) TBARS values than control during frozen storage (45 days of storage at -18°C). Meat products incorporated with different plum products exhibit lower lipid oxidation. However minor flavor differences and some color variations have been observed, but sensory analysis showed no significant differences in color and flavor attributes (Karre et al., 2013).
Grape Seed Extract
Grape seed extract has antioxidant potential 20 and 50 times higher than vitamin E and vitamin C, respectively and has been reported to be the richest sources of natural poly phenols, comprising flavanols, phenolic acids, catechins, proanthocyanidins and anthocyanins (Karre et al., 2013; Hygreeva et al., 2014). The major poly phenols are catechins and proanthocyanidins representing about 77.6% of total (Silvan et al., 2013). Earlier researchers compared grape seed extract at different concentrations (100, 300, 500ppm) with ascorbic acid and propyl gallate (100ppm of fat) in lean beef sausages cooked (70 °C) sliced and stored at −18 °C for 4 months and observed that samples prepared with the grape seed extract (100, 300ppm) and propyl gallate retained their freshness, had less rancid odour and had lower thiobarbituric acid reactive substances (TBARS) values compared to controls and ascorbic acid containing samples during the storage period (Kulkarni et al., 2011). Özvural and Vural (2011) concluded that, frankfurters prepared with addition of different concentrations (0, 0.5, 1, 2, 3, 4, 5%) of grape seed flour, had lower oxidation level and enhanced protein and total dietary fiber content with increasing levels of grape seed flour (Özvural and Vural, 2011). Additionally the effect of grape seed extract at different levels (0.01, 0.03, 0.05, 0.1, 0.3 and 0.5%) on the quality properties of frankfurters was evaluated against the control. The results showed that with the increase in level of grape seed extract in frankfurters there was a decrease in the TBARS values of the products (Ozvural and Vural, 2012). Garrido et al., 2011 studied the effect of two different types of red grape pomace extracts (GPI and GPII) at a concentration of 0.06 g/100 g final product, in pork burgers packed under aerobic conditions at 4 °C for 6 days. It was observed that GPI showed the highest color stability, lipid oxidation inhibition and the best global acceptability after 6 days of storage. In addition grape seed extract (GSE), oleoresin rosemary (OR), water-soluble oregano extract (WO), propyl gallate (PG), butylated hydroxyanisole (BHA), and butylated hydroxyl toluene (BHT) in cooked, frozen, reheated ground beef patties, overwrapped in commercial PVC film, and stored frozen (−18°C) for 6 months was investigated (Colindres and Brewer, 2011). It was concluded that PG and GS treated samples showed lower rancid odor scores and TBARS values than controls, after 6 months of storage. BHT treated and control samples did not differ statistically in sensory grassy or rancid odor, indicating that they were the most oxidized.
Pomegranate fruit parts contain a high concentration of antioxidants and the peel and rind are good sources of tannins, anthocyanins, and flavonoids (Naveena et al., 2008a). Hygreeva et al. (2014); Ganhão et al., (2010) reported that pomegranate fruit phenolics to meats inhibit lipid and protein oxidation through radical chain inhibition and thus prevent color deterioration in the product. Devatkal et al. (2012) investigated the effect of vacuum packaging and pomegranate peel extract on ground goat meat and cooked nuggets during refrigerated storage (4 ± 1 °C). Vacuum packaging along with 1% pomegranate peel extract (VP + PPE) showed significantly lower TBARS than atmospheric packaging. In ground meat, VP + PPE reduced the TBARS by 41% while in nuggets, it was decreased by 40%. Devatkal et al. (2010) investigated the use of kinnow rind powder (KRP), pomegranate rind powder (PRP), and pomegranate seed powder (PSP) (10 ml of extract) in raw goat meat, and then prepared cooked goat (80 ºC) patties. Addition of PRP was effective in reducing TBARS formation up to 67% (p < 0.05). Additionally in another study, Devatkal and Naveena (2010) studied effect of salt, kinnow rind powder (KRP), pomegranate rind powder (PRP), and pomegranate seed powder (PSP) in raw ground goat meat. The addition of fruit powders showed lower (p < 0.05) TBARS compared with control and salted samples. Pomegranate rind powder (PRP) incorporated patties showed higher reduction in TBARS values (134% and 443%) compared with control and salted samples, respectively. The effect of pomegranate fruit juice phenolics (PFJP) solution on the shelf life of chicken meat held under refrigerated storage at 4 ºC was evaluated by Vaithiyanathan et al. (2011). TBARS were evaluated in 2 days intervals for 28 days and reported that TBARS values were lower in samples treated with PFJP.
Avocado is one of the lesser-studied natural antioxidants. Rodríguez-Carpena et al. (2011) investigated the antioxidant activity of peel and seed extracts from two avocado varieties– Hass and Fuerte and observed that during chill storage of raw porcine patties for 15 days the addition of peel and seed extracts resulted in lower TBARS values, and significantly reduced the color loss. In addition Hass avocado extract significantly inhibited the formation of protein carbonyls in the chilled patties. These studies demonstrate that avocado has potential to work as a natural antioxidant in meat.
Apple pomace is the primary by-product of apple juice manufacturing, and approximately 3.0–4.2 9 106Mton/ year are generated annually worldwide. A range of polyphenolic compounds have been isolated from apple pomace, such as epicatechin, caffeic acid, phloridzin, phloretin-20-xyloglucoside, 3-hydroxyphloridzin, avicularin, reynoutrin, hyperin, isoquercitrin and quercitrin (Rather et al., 2015a); 2016c which have antioxidant property (Olano-Martin et al., 2003; Cetkovic et al., 2007; Huda et al., 2014). Rather et al., (2015a); 2016c evaluated apple pomace powder at different levels (1–5 %) in traditional Indian meat product (Goshtaba).The addition of apple pomace powder resulted significantly lower TBARS values in uncooked and cooked products and metmyoglobin percent in uncooked meat emulsions than both high fat and low fat samples.
Tomato is most cultivated vegetable all around the world. The Presence of high amounts of lycopene in tomato, which is a natural colorant of (red) and antioxidant is a functional ingredient that can be used in meat products (Hygreeva et al., 2014). Garcia-Closas et al. (2004) reported that tomatoes are a rich source of natural antioxidants such as lycopene (71.6%), vitamin C (12.0%) and β-carotene (17.2%) and vitamin E (6.0%). Doménech-Asensi et al. (2013) reported that the addition of 10% tomato paste (TP) during the manufacture of mortadella improved the nutritional status (Lycopene), color stability and decreased lipid oxidation during 2 months storage at 4 °C. It has been observed that the MDA content in the regular product (R) increased significantly from initial values of 42.05 to 59.17 mm MDA/100 g while TP incorporated product showed values in the range of 30–40 mm MDA/100 g for the storage period of 2 months. Thus more investigation needs to be conducted for other varieties of meat products with a focus on different storage conditions.
Choe et al. (2011) evaluated the antioxidant activity of lotus leaf powder, 0.1% (LP1), 0.5% (LP2) and barley leaf 0.1% (BP1), 0.5% (BP2) powder in cooked ground pork and reported that addition of LP2 or BP2 significantly decreased lipid oxidation and lowered peroxide and conjugated diene values when compared with control samples containing BHT (0.01%) during refrigerated storage for 10 days. There were no significant changes observed in overall acceptability among the treatment groups (LP/BP). Qi and Zhou (2013) found that addition of epicarp extract of lotus seed at 6.25, 12.5, 25, 50 and 100μg mL−1 concentrations to pork homogenates retarded TBARS and peroxide values in Chinese Cantonese sausages. Moreover the cytotoxic and anti obesity activity of the extract in vitro in 3 T3-L1 pre adipocyte cell models depended on the dosage; epicarp extracts of lotus seed are potent antioxidant and anti obesity phyto chemicals with no toxic effects. Huang et al. (2011) investigated that extracts from lotus rhizome knot (3% w/w, LRK) and lotus leaf (3% w/w, LL) incorporated in porcine and bovine meat samples stored at 4 °C for 10 days increased antioxidant activity of meat samples, but LRK was more effective against lipid oxidation.
Natural antioxidants from herbs and spice extracts
Extracts of herbs and spices have been used as natural antioxidants in meat and meat products by several authors (Table 1). The increasing interest of meat industry in natural antioxidants led to an extensive research on the utilization of spices and herbs lipid oxidation inhibitors. Spices have been shown to have potential antioxidant properties due to the presence of several compounds such as polyphenolics, flavanoids, lignans, and terpenoids (Karre et al., 2013). The herb and spice extracts, including rosemary, oregano, clove, and thyme have been studied for their antioxidant potential in cooked, fermented and irradiated meat products (Rodríguez Vaquero et al., 2010). Rosemary and rosemary extracts are the most studied natural antioxidants used in meat and poultry products (Rojas and Brewer, 2007). Rosemary (Nutrox-30 mg/100gm) and lemon balm (Melinox-30 mg/100g) extracts in cooked pork meat patties packed in modified atmosphere were evaluated by Lara et al. (2011). They observed that natural extracts significantly reduced the TBARS values and hexanal contents in products during 3 days storage under illumination. Trindade et al. (2010) evaluated the rosemary (400 mg/kg) and oregano (400 mg/kg) extracts individually or in combination (200 mg rosemary plus 200 mg oregano) and with either BHA/BHT (200 mg/kg) or their blend (100 mg/kg BHA/BHT plus 200 mg/kg rosemary/oregano) in irradiated beef burgers and proved decreased lipid oxidation (TBARS values 2.7 mg/kg – control, treated samples-below 2.0 mg/kg) in meat samples stored at −20 °C for 90 days. Moreover, rosemary alone or in combination with either BHA/BHT or oregano showed the highest inhibitory effect among all the formulations. Boerewors, a South African fresh sausage, was treated with rosemary (260 mg/kg) and compared with 450 mg/kg sulphur dioxide (SO2). Addition of rosemary showed comparable lipid stability to SO2. Reduced levels of 100 mg/ kg SO2 showed good color effects in combination with rosemary as antioxidant and improving the sensory properties (Mathenjwa et al., 2012). Mohameda et al. (2011) investigated that addition of herbal extracts of marjoram, rosemary and sage at concentration of 0.04 % (v/w) to ground beef prior to irradiation (2 and 4.5 kGy) significantly reduced the TBARS values. Naveena et al. (2013) evaluated the effect of oil soluble and water dispersible carnosic acid (CA) extracted from dried rosemary leaves at two different concentrations (22.5ppm and 130ppm) in raw and cooked ground buffalo meat patties. It was observed that CA extracts lowered (P < 0.05) the TBARS by 39–47% at lower concentration (22.5ppm) and by 86–96% at higher concentration (130ppm) in cooked buffalo meat compared to controls. The CA extracts were also effective in inhibiting (P < 0.05) peroxide value and free fatty acids in cooked buffalo meat patties. Mint leaf extract was evaluated for its antioxidant activity in raw ground pork meat stored at 4 ± 1 °C (Biswas et al., 2012). It was reported that the water extract of mint leaf (WEM) showed a decrease in the Hunter L* and a* values and an increase in b* value during storage. The TBARS values were reduced due to the incorporation of WEM leaf extracts during storage periods. Tajik et al. (2014) studied the effect of clove essential oil (0.1%) on lipid oxidation of raw buffalo patties during storage at 8 °C for 9 days and observed a lower TBA values in samples 0.1% clove essential oil. Samples with 0.1% clove essential oil had the lowest degrees of lipid oxidation, which was 73% lower than the control. Rababah et al. (2011) evaluated the effect of green tea or grape seed extract alone (3000 and 6000ppm) or combination with TBHQ (200ppm) on lipid oxidation and the redness of goat meats stored at 5 °C for 9 days was evaluated. The antioxidant activity of the plant extracts and the TBHQ ranged from 4.6 to 10.2 h induction time using an oxidative stability instrument. Plant extracts and TBHQ significantly decreased lipid oxidation of the goat meats. Further, higher level addition of antioxidants was more effective in minimizing lipid oxidation. Wojciak et al., (2011) investigated the extracts from green tea (catechins, epigallocatechins), rosemary (rosmariquinone, rosmaridiphenol) and red pepper (capsaicinoids) in pork meat products stored for 30 days at refrigerated temperatures. All these plants extracts effectively reduced the lipid oxidation in cooked pork compared to the control. Lipid oxidation was reduced (P < 0.001) in raw and cooked pork patties stored in aerobic packages and in MAP (80% O2:20% CO2) treated with sesamol, ellagic acid and olive leaf extract. Addition of lutein, sesamol, ellagic acid and olive leaf extract to pork showed a antioxidant potential and was in the order: sesamol = ellagic acid + olive leaf extract + lutein (Hayes et al., 2010). Hayes et al. (2011) evaluated the lutein (200 μg/g meat), sesamol (250 μg/g meat), ellagic acid (300 μg/g meat) and olive leaf extract (200 μg/g meat) in fresh and cooked pork sausages stored in aerobic or modified atmosphere packages (MAP). Incorporation of sesamol, ellagic acid and olive leaf extract reduced (P < 0.001) lipid oxidation in all packaged raw and cooked pork sausages.
During recent past there has been an increasing interest in using natural ingredients in meat and meat products. Consumers have increasingly favored meat products which contain natural additives due to concerns over adverse health effects of synthetic substances particularly some synthetic antioxidants. Oxidation has various detrimental effects on quality of meat and meat products such as discoloration, development of rancid flavor and loss of functional properties which renders the products unpalatable and unacceptable. In addition, oxidation of lipids and proteins poses serious health risks besides being a major threat to meat quality. Due to the adverse health effects of synthetic antioxidants; fruits, vegetables, herbs, spices and other plant extracts provide good alternatives to combat such problems in meat products in addition to increasing the health promoting bioactive components. However, since the effect of natural antioxidants on quality of meat and meat products has not been fully investigated, there is a need to explore this area to curb the challenges of quality losses in fresh and processed meat and meat products due to oxidation.
