tailieunhanh - Whey based biopolymeric coating as an alternative to improve quality of fresh fruits (malpighia emarginata d.c.) from southern Brazil

Edible coatings were produced using whey (30% and 60%) and glycerol. Samples were compared to a control (no coating), during storage at both temperatures. Storage at 10 °C improved the maintenance of the acerola colour, while storage at 5 °C increased the stability of vitamin C and decreased microbial growth (p ≤). The application of edible coating reduced the total colour variation and degradation (a*) at both temperatures. The concentration of whey influenced significantly (p≤) on the vitamin C content (A10-60), and on the mesophilic (A5-60 and A10-60) and psychrotrophic bacteria (A10-60) counts. |
