Packaging and storage of minimal processed garuc (Aluum satlvum L)

The effect of different types of packaging material and storage condition on the quality of minimal processed garlic was studies. Two varieties of garlic i.e. PG 01 and PG-117 commonly grown in Punjab were packed in different polymeric films with common thickness of 37.5um viz. high density polyethylene (HDPE), low density polyethylene (LDPE), polypropylene (PP) and in a plastic tray as a control. Samples were stored at ambient and refrigerated conditions. Changes in moisture content and color occurred linearly in all the packaging materials. The minimum change in moisture content and color of peeled cloves was observed in LDPE for both the varieties and storage condition. It has been concluded that out of the two varieties PG-01 has longer storage life than the latter. Garlic cloves could be stored in LDPE film for 5 days at room temperature and more than 15 days at refrigerated conditions. Statistical analysis showed that storage period, storage condition and packaging material have a significant effect at 5% level of significance on the moisture content and color of the samples; whereas variety has a non significant effect on the quality parameters.
