tailieunhanh - Storage stability of guava leather in two type of packaging

Guava (‘Allahabad Safeda’) leather was prepared as per FSSAI specification and the effect of packing in punnet and biaxially oriented polypropylene was carried out to study the effect of storage under ambient condition (25 ± 5∘C). The storage stability, nutritional and microbial quality and sensory changes were evaluated periodically upto 4 months. The leather stored in biaxially oriented polypropylene recorded higher nutrient retention compared to packaging in punnets. There was reduction in moisture, ascorbic acid, non-reducing sugar, total sugar and water activity irrespective of packaging material during storage while acidity, reducing sugar and non-enzymatic browning showed significant increase during the storage. Microbial analysis showed the leathers were safe for consumption till 4 months of storage in both packaging. Sensory acceptability were higher in the samples stored in biaxially oriented polypropylene and remains acceptable upto 4 months of storage. | EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 8 Number 07 2019 Journal homepage http Original Research Article https Storage Stability of Guava Leather in Two Type of Packaging L.

Introduction Guava Psidium guajava L. belongs to family Myrtaceae and is a native of tropical America. It is one of the important commercial fruit of tropical as well as subtropical regions. It emits a sweet aroma and is pleasantly sweet and refreshingly acidic in flavour. It ranks third in ascorbic acid content 260 mg 100 g pulp after barbados cherry
