Salvaging Cashew Apples Through Processing into Simulated Cashew Meat

Abstract

Cashew tree (Anacardium occidentale) is a cash crop mainly grown for its nuts. The dried apple is a good source of protein and non-digestible fibre that is essential to prevent many diseases as it helps in bowel movements to remove waste and non-digestible food materials from human system. The dried apple was obtained from extracting juice from the whole apple before drying. The use of apple which is a by-product can be an opportunity for diversifying activities on the farm. The farmers' revenue can increase through various opportunities which, exist for using cashew apples. However, these opportunities are presently not utilised adequately since most farmers are of the peasant status and has no knowledge on how to process the apple. Due to its high rate of perishability, cashew apples will not require to be transported over long distances and need to be processed, if possible, at the farm settlements. Simulated cashew meat was processed by subjecting cashew apple to juice pressing, blanching, salting and different methods of drying. The products obtained were subjected to physiochemical analysis, sensory evaluation and shelf-life studies. The percentage values for pH, moisture, crude protein and crude fiber contents were 4.71, 9.33, 18.31 and 14.32 respectively. The meat-like substance developed from cashew apple was very similar to dry meat. The sensory analysis revealed that there were no significant differences between processed cashew meat when compared with dry meat. The products were stable at room temperature for three months, studies on going to extend the shelf life further. Production of simulated cashew meat as a substitute for both meat consumers and vegetarians had come as a way of adding value to cashew apples that waste away in our cashew farms during peak seasons.
