Shelf-life prediction for Indian mango roll using accelerated shelf-life testing (ASLT) shelf-life plot approach

Indian mango roll is a sweet and chewable after-meal sugar fix. It is prepared from the puree of Indian mango and dried to form a glossy sheet. Ripe raw Indian mango generally has a short shelf-life. Osmotic-dehydration is one way to extend the shelf-life of Indian mango. Changes in color and flavor were considered as critical aspects upon long-term storage at accelerated temperatures. This research aimed to predict the shelf-life of Indian mango roll with Accelerated Shelf-life Test methods. Indian mango rolls packed in 30 g stand up aluminum foil with polyethylene liner were stored at three different temperatures, 35°C and 45°C for temperature acceleration, and 30°C for the actual temperature for one hundred eighty (180) days. The storage of Indian mango roll at 30°C, 35°C, and 45°C is predicted until 255 days, 244 days, and 69 days, respectively, based on the test results for the conducted microbiological, physicochemical and sensory analyses. The results implied that the Indian mango roll can be stored long enough before becoming unfit for consumption or sale.
