ABSTRACT
In modified atmosphere packaging of guava, moisture scavenger (MS) sachet containing 30-50â¯g of coarse silica gel and ethylene scavenger (ES) sachet containing 0-4â¯g of potassium permanganate was added as per central composite rotatable design. The headspace O2 and CO2 of the packages were studied at 4, 8 and 12⯰C for 30â¯days and thereafter the guava were left for two days to ripen at 30⯰C. After that the chilling injuries, percentage acceptable guava, peel color and pulp texture was analyzed. After two days ripening at 30⯰C the samples with 3â¯gâ¯ES and 46â¯gâ¯MS registered higher L∗, lower a∗ value & firmness (16.65â¯N), lowest chilling injury score. About 95% of guava was found acceptable in this treatment with 1.89-2.79% reducing sugar, 0.95-1.1% titrable acidity, 59% and 46.61% retention of total phenols and ascorbic acid respectively, resulting 32â¯days shelf-life of guava.
