Abstract

This paper focuses to preserve grapes in Fridgesmart container by means of MAP. Before storage, grapes are pre-treated with 1 ppm ozone solution in 10 minutes for similarity of total microbial denisty on the samples. Then the grapes are stored in the Frigesmart container (400 g grapes / box ) and control sample (no storage box, placed on the plastict tray PS_Poly styren). During preservation, I checked 1 time / 5 days of parameters: weight, soluble solids, vitamin C, pH and total aerobic bacteria. Laboratory results achieved: no differences more weigh, solube solid (α=0.05%) ; Vitamin C reduced by about 9 times after 15 days of storage (α=0.05%); Shelf-life of grapes in Frigesmart container of 13 days.

Key words: MAP; preservation, vegetables, grape.
