ABSTRACT
An experiment was carried out during 2009-10 to study the effect of irradiation on extension of shelf life and qualitative changes occurred during post harvest life of sapota fruits. The treatments consists of irradiation at 0.2 kGy, 0.4kGy, 0.6kGy and 0.8kGy including control and was replicated 4 times under CRD experiment. It was conducted at PHT lab, College of Horticulture, Rajendranagar and irradiation unit, ANGRAU. The results of the experiment revealed that the irradiation treatments at 0.20 kGy recorded lower physiological loss in weight (14.73%), spoilage (31.52%), ripening (59.75%), brix: acid ratio (114.55), higher firmness (1.97kg/cm2), acidity (0.15%), total soluble solids (23.430B), reducing sugars (8.46%), total sugars (11.98%) and highest organoleptic score (8.12) over all other treatments and thereby recorded higher shelf life of 12.00 days.
Key words :
Irradiation, Post harvest shelf life, Quality attributes, Sapota fruits.
