Abstract

The physicochemical and microbial changes in fresh chickpea sprouts during MA storage at 10°C temperatures and 75 % RH and ambient were examined by monitoring chickpea sprouts weight loss, pH, hypocotyl color changes, texture in terms of hardness, supported by overall visual quality evaluation and microbial infection by yeast and mold enumeration. Under MA storage, chickpea sprouts having different void volume in PP and LDPE polymeric films were stored for a week at 10°C temperature under MAP. In-pack gaseous composition was least in PP as compared with LDPE polymeric films. The PLW (%) was significantly lesser in 200g pack followed by 100; 150 g of sprouted chickpea samples packed PP films than those in LDPE polymeric film packs. Best hardness was maintained by 200g PP and 150g LDPE packaging treatment. Visual evaluation indicates that chickpea sprouts sample packed in 200g PP package received highest significant score. Yeast and mold growth appears to significantly contribute to microbial spoilage of chickpea sprouts, using modified atmosphere may restrict the spoilage problems caused by molds and yeast. Chickpea sprouts packed in Polypropylene (PP) was highly effective in maintaining the physic-textural and microbial analysis as evident by visual evaluation. The LDPE film package did not favorably affect the storage life of chickpea sprouts
