Physical and chemical characteristics of beef marinated by cashew apple extract

Abstract

Marination is one of the methods that are often used in beef processing in an attempt to obtain high quality of beef. Cashew apple extract marinade (CAM) improves the microbiological characteristics of meat by inhibiting the growth of meat bacteria. The effect of CAM on other aspects such as physical (microbiological, tenderness, cooking loss, water holding capacity and pH) and chemical (moisture, fat and protein content) characteristics of meat have not been evaluated, which would be beneficial for the utilisation of agroindustry waste in the meat industry. In this study, the effect of CAM on the physical and chemical characteristics of beef, including microbiological characteristics, tenderness, cooking loss and water holding capacity, was evaluated. CAM (0%, 10%, 20% and 30%) was used during beef processing for 4 h at refrigeration temperature. Significant effects of CAM were observed on the physical and chemical characteristics of beef. CAM increased beef tenderness and reduced total bacteria, cooking loss, moisture, fat, and protein content. The optimum concentration of CAM for which significant changes were observed in the physical and chemical characteristics of beef was 20%. Thus, cashew apple can be utilised as a promising marinade agent in beef processing with the criteria of food for specific health use. This approach will help reduce cashew apple waste and is an eco-friendly approach.
