Production Process of a Nutritional Drink from Mango (<i>Mangifera indica</i>)

Abstract

The aim of study was to determine optimal formulation and microwave parameter to pasteurize mango juice products to maintain the most nutrients and organoleptic level. Raw material and drinking product were assessed for properties including vitamin C content (mg/100ml), total polyphenol content (mgGAE/100ml) and antioxidant activity (% free radical scavenging ability). Besides, factors influencing the quality of mango juice including material to water ratio (w/w), material to syrup ratio (w/w), citric acid content (w/w), microware power (watt) and microware time (minutes) was examined. As a results, the mango:water dilution ratio as 1:2 (w/w); rate of mango:syrup as 1:2 (w/w); citric acid content as 0.3% (w/w); microwave power as 400 watt and microwave time of 3 minutes were suitable for achieving product with good nutritional and sensory quality. At these conditions, vitamin C content was 8.42 mg/100ml, total polyphenol content was 47.543 mgGAE/100ml, and DPPH free radical activity was 11.191%. The results also justified the role of mango as a new ingredient in beverage industry and suggested using microwave to pasteurize as an appropriate method for manufacturing drinking products from fruit.
