Shelf Life Evaluation of Fortified Soynut-Chikki using Different Packaging Materials

Fortified soynut-chikki was developed using de-oiled groundnut meal and puffed soynuts as one of the main ingredients to explore its nutritional benefits. Prepared Fortified soynut-chikki was stored in two different packaging materials viz., PP (Polypropylene) and MP (Metalized polypropylene) packs to analyze the storability of fortified soynut-chikki at ambient condition (28±2°C). The microbial load, sensory characteristics (Overall acceptability scores), physico-chemical properties viz., moisture content, water activity, FFA (Free Fatty Acid) values, color (L* values) and hardness of fortified soynut-chikki following each packaging materials such as (PP and MP) pack were also evaluated during storage period of 135 days at a frequency of 15 days at ambient condition. Metalized polyester (MP) pack was found to be most effective packaging material for better storability of fortified soynut-chikki having shelf life up to 120 days at ambient condition (28± 2°C).
