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 focus on the effect of Sorghum bicolour on the quality characteristics of chevon cutlets and to evaluate the effect of clove oil on the storage quality of aerobically packaged chevon cutlets. Design/methodology/approach – Three levels of sorghum flour, namely, 2, 4 and 6 per cent, were incorporated in the formulation, and the products developed were assessed for various physicochemical, sensory, texture and colour parameters. Chevon cutlets containing optimum level of sorghum flour were treated with clove oil (100 ppm) and evaluated for storage quality for 15 days under refrigerated conditions (4 ± 1°C). The products were analysed for various physicochemical, microbiological and sensory parameters. Findings – Crude fibre, texture parameters, i.e. hardness, adhesiveness, springiness, cohesiveness, chewiness, gumminess and product redness value, showed significant (p < 0.05) increasing trend, whereas moisture per cent, fat content and overall acceptability decreased significantly (p < 0.05) with increasing levels of incorporation. Chevon cutlets containing 6 per cent sorghum flour were optimized as best. Thiobarbituric acid-reactive substance value (mg malonaldehyde/kg), total plate count (cfu/g) and psychrophillic count (cfu/g) showed a significant increasing trend (p < 0.05), whereas all the sensory parameters decreased significantly (p < 0.05) with increasing days of storage. The products were successfully stored for 10 days under refrigerated conditions (4 ± 1°C) without marked loss in quality. Originality/value – The paper has demonstrated the potential of sorghum as a fibre source in the development of designer chevon cutlets and effect of clove oil on the storage quality of aerobically packaged chevon cutlets.
