ABSTRACT
The study was conducted with an objective to evaluate the effect of Aloe vera gel and Arjun (Terminalia arjuna) bark extract on shelf life of buffalo male calf meat rolls at refrigeration (4±1°C) storage. The meat rolls were prepared with incorporation of 4% Aloe vera gel (T1) and 2% Arjun tree bark extract (T2) and compared with control (C) meat rolls. The products were assessed for their physico-chemical, sensory and microbiological quality at 0, 4, 8, 12, 15, 18 and 21 days. However, the sensory scores and moisture content decreased and microbial load, TBA value and free fatty acids (FFA) increased as the days of storage increased for control as well as treated products. The rate of decline in sensory score and moisture content and rate of increase in microbial load, TBA vale and FFA during storage were higher in control samples as compared to treated (T1 and T2) meat rolls. It was concluded that Aloe vera gel (4%) and Arjun tree bark extract (2%) incorporation showed their antioxidant and antimicrobial effects, by keeping the treated products organoleptically acceptable and microbiologically safe up to 21 days of refrigeration storage.

While food has long been used to improve health, our knowledge of health is now being used to improve foods. The understanding of relationship between nutrition and health has resulted in the development of concept of functional foods. A promising approach in improving health care is zeroing on to produce a healthier food supply as preventive health care strategy (Decker and Park, 2010).
The processing of meat leads to generation of many functional compounds beneficial to human health but also pose a health hazard due to high amount to added salt and fat that somehow is proved to be a predisposing factor for cardiovascular diseases, diabetes mellitus and cancer (Cross et al., 2010).
