Antioxidant Content of Selected Mango Varieties and Their Correlation with the Shelf-Life of Developed Products

This work is concerned with the role of inherent antioxidants content of selected mango varieties on the quality and shelf-life of developed mango products. Three mango varieties as gutti, ashina, and langda and two mango products; mango bar and mango fruit drinks were used as factors of this study. The samples of ripe mangoes are collected from several places of Bangladesh. Antioxidant contents of three varieties of mango pulp and microbial loads as influenced by the inherent antioxidant of mango bar and mango fruit drinks with time were assessed. All three varieties contained vitamin A, beta carotene, and vitamin C as antioxidant and their contents were higher in gutti variety than other two varieties; Asina and Langda. These inherent antioxidants were made an effective role to resist microbial load in the mango products like mango bar and mango fruit drink. No microbial growth was observed within three months in the products (mango bar and mango fruit drink) of gutti mango variety except TPC, which showed slight growth after four months of storage. In the product of other two varieties Asina and Langda were affected by microbial growth (TPC) within one and two months consecutively. The study discloses that the inherent antioxidant content of mango varieties had significant effect on the quality and shelf life mango products.
