Purpose – The purpose of this study is to explore the possibility of utilization of lemon peel extract as a natural antioxidant source in muscle foods. The products incorporated with lemon peel extract were assessed for various oxidative stability and storage quality parameters. Design/methodology/approach – The study was designed to evaluate the effect of lemon peel extract on the oxidative stability and storage quality of Tabak-Maz, a popular traditional meat product. The products were prepared and treated with different concentrations of lemon peel extract (0.5, 1, 1.5 per cent) and were aerobically packaged in low-density polyethylene pouches and assessed for lipid stability and storage quality parameters under refrigerated (4 ± 1°C) conditions. Findings – Lemon peel extract showed a significant (p < 0.05) effect on the lipid stability of the products as the treated products exhibited significantly (p < 0.05) lower thiobarbituric acid-reactive substances (TBARS) (mg malonaldehyde/kg) and free fatty acid (FFA) (per cent oleic acid) values for the entire period of storage. A significant (p < 0.05) effect was also observed on the microbiological characteristics of the products, as lemon peel extract treated products showed significantly (p < 0.05) lower values for total plate count, psychrophillic count and yeast and mould count throughout the period of storage. Coliforms were not detected throughout the period of storage. Significantly (p < 0.05) higher scores were observed for various sensory parameters of the treated products. Originality/value – Lemon peel extract successfully improved the oxidative stability and storage quality of Tabak-Maz during refrigerated (4 ± 10°C) storage and may be commercially exploited as a natural antioxidant source in muscle foods.

Purpose The purpose of this paper was to explore the antioxidant and antimicrobial properties of locally available herbs, namely, Bacopa monnieri in enhancing the shelf life of chicken nuggets. Design/methodology/approach Meat products are highly vulnerable to spoilage due to their excessive fats and protein content. Therefore, chicken nuggets incorporated with 1, 2 and 3 per cent Bacopa monnieri extracts and control chicken nuggets, were studied to explore the potency of this locally available herb on oxidative stability and storage quality of chicken nuggets on the 0,7th,14th and the 21st day at the refrigerated storage (4 ± 1°C). Findings Extracts of Bacopa monnieri were prepared and optimally incorporated in the chicken nuggets. Chicken nuggets prepared with 2 per cent of Bacopa monnieri were adjudged as the best among all based on sensory attributes. Extracts of Bacopa monnieri-incorporated nuggets were safe for consumption until 21 days of refrigerated storage (4 ± 1°C), based upon the power of hydrogen (pH), free fatty acid (FFA), thiobarbituric acid reactive substances (TBARS), microbiological profile and sensory evaluation of the chicken nuggets. Practical implications Two per cent of Bacopa monnieri extracts’ incorporation in the chicken nuggets successfully improved the oxidative stability and storage quality of chicken nuggets and, therefore, can be commercially exploited. Social implications The Bacopa monnieri herb is commonly available in the Jammu region of Jammu and Kashmir state in the Indian Republic; hence, it can be used in its extract form in meat products, to make the products function with enhanced shelf life. Originality/value The addition of 2 per cent extracts of Bacopa monnieri in the chicken nuggets successfully improved the oxidative stability and its storage quality during the refrigerated (4 ± 1°C) storage. Therefore, it can be commercially exploited to improve the storage quality for longer duration of the meat food without adversely affecting the sensory quality of the products.

Purpose This paper aims to to explore the possibility of utilization of Ipomoea batatas as a novel binding agent for hot-set restructured meat products. Further, green coffee bean (GCB) extract was used as a natural ingredient to improve the lipid oxidative stability and storage quality of the developed restructured mutton blocks. Design/methodology/approach Restructured mutton blocks were used as a model and were prepared by incorporating different levels of I. batatas, namely, 1, 3 and 5 per cent and analyzed for various quality parameters. Restructured mutton blocks containing optimum level of I. batatas were further treated with GCB (1 per cent) extract as a natural ingredient and assessed for various lipid oxidative stability and storage quality parameters under refrigerated conditions (4 ± 1°C). Findings Restructured mutton blocks containing 3 per cent level of I. batatas were optimized as best on the basis of various quality parameters. Although a significant declining trend was observed in the sensory characteristics with storage; however, the products containing GCB extract showed significantly (p < 0.05) higher acceptability. The mean scores for overall acceptability for products with GCB extract on day 0 was 7.4 ± 0.1 and for control was 7.3 ± <0.1. Significantly (p < 0.05) lower thiobarbituric acid reacting substances (TBARS, mg malonaldehyde/kg) and free fatty acid (FFA, % oleic acid) values were observed for the products containing GCB extract. The mean TBARS and FFA values for products with GCB extract on day 0 were 0.2 ± <0.1 and 0.08 ± <0.1 and for control were 0.3 ± <0.1 and 0.09 ± <0.1, respectively. The restructured mutton blocks containing GCB extract also showed significantly (p < 0.05) lower values for various microbiological characteristics like total plate count (log cfu/g) and psychrophilic count (log cfu/g). Originality/value The results showed herein indicate a promising industrial application of I. batatas (3 per cent) as a binding agent for restructured meat products and GCB extract (1 per cent) as a novel natural ingredient for improved lipid oxidative stability and storage quality.

Purpose Pomegranate rind has been reported to have strong antioxidant and antimicrobial properties. The study was conducted to evaluate the possibility of using pomegranate rind extract as an efficient alternative to synthetic antioxidants and preservatives in fat-rich meat products, which are highly susceptible to lipid oxidation. Design/methodology/approach Tabak-Maaz, a fat-rich meat product, was used as a model system and treated with different concentrations of pomegranate rind extract (0.5, 1.0 and 1.5 per cent) and aerobically packaged within low-density polyethylene pouches and assessed for lipid oxidative stability and storage quality under refrigerated (4 to 1°C) conditions. The products were evaluated for various physicochemical, microbiological and sensory parameters at regular intervals of 0, 7, 14 and 21 days. Findings Pomegranate rind extract showed a significant (p < 0.05) effect on the lipid oxidative stability, as the treated products exhibited significantly (p < 0.05) lower TBARS (mg malonaldehyde/kg) values. A significant (p < 0.05) effect was also observed on the microbiological characteristics of the products, as treated products showed significantly lower values for microbial and yeast and mould counts and for free fatty-acid (% oleic acid) values. Sensory parameters showed significant (p < 0.05) decreasing trend for both control as well as treated products throughout the period of storage; however, significantly (p < 0.05) higher scores were observed for pomegranate rind extract-treated products when compared to the control. Originality/value Pomegranate rind extract successfully improved the lipid oxidative stability and storage quality of the products during refrigerated (4 ± 1°C) storage and may be commercially exploited by the meat industry as an efficient alternative without adversely affecting the sensory quality of the products.

Purpose – The purpose of this study was to explore the potential of Aloe vera as a novel source of natural antioxidant and preservative in the muscle foods and to evaluate the effect of Aloe vera on the storage quality of aerobically packaged chicken nuggets. Design/methodology/approach – The Aloe vera pulp was incorporated at various levels, namely, 0, 5, 10 and 15 per cent, replacing lean meat in the formulation. The products were analyzed for proximate composition, physicochemical and sensory parameters. Chicken nuggets incorporated with optimum level of Aloe vera (10 per cent) along with control nuggets (0 per cent Aloe vera) were aerobically packaged and assessed for lipid oxidation, physicochemical and microbiological characteristics under refrigerated (4°C) conditions. Findings – pH, crude protein, ether extract and ash content of the nuggets showed significant (p < 0.05) decreasing trend with increasing levels of Aloe vera; however, there was a significant (p < 0.05) increase in the moisture content, emulsion stability and cooking yield. Aloe vera-enriched nuggets showed significantly (p < 0.05) lower values than control nuggets for almost all the lipid oxidation and microbiological parameters, i.e. free fatty acid, thiobarbituric acid-reactive substances value, total plate count, psychrophillic count and yeast and mould count. No significant (p > 0.05) difference was observed in the sensory parameters of the Aloe vera-enriched nuggets and the control samples throughout the period of storage. Originality/value – The paper has demonstrated the use of Aloe vera as a potential natural antioxidant without any marginal decline in the sensorial characteristics and nutritive value of the muscle foods.
