Influence of Blanching Temperature and Time on Quality of Minimally-Processed Mango during Frozen Preserva

Abstract

Mango (Mangifera indica L.) is one of the most important tropical fruits. It’s excellent source of nutrients, soluble fibres, bioactive compounds such as carotenoid, ascorbic acid and phenolic.  Mango pulp is very perishable with a short shelf life. It is very vulnerable to dehydration, discoloration, and decomposition. Objective of this study focused on the effectiveness of blanching (60^oC in 4 minutes, 65^oC in 3.5 minutes, 70^oC in 3 minutes, 75^oC in 2.5 minutes, 80^oC in 2 minutes) to physico-chemical attributes of the minimally-processed mango during frozen storage for 6 months. Our results showed that minimally-processed mango should be blanched in hot water at 75^oC for 2.5 minutes to maintain its shelf-life and physico-chemical characteristics during 6 months of frozen storage.
