Abstract: The present investigation was conducted to study the response of different chemicals on post-harvest life and quality changes in guava at successive intervals of storage. Fruits of winter season were treated with Aloe vera (15, 20 and 25 %) and two antioxidant chemical viz; ascorbic acid (750, 1000 and 1500 ppm) and benzyl adenine (50, 100 and 200 ppm) along with control. Among various treatments tested, 20% Aloe vera treatment was found effective in extending the shelf life as it retained greater firmness (2.59 kg cm-2), ascorbic acid (133.93 mg/100 g pulp), superoxide dismutase (359.04 µg-1min-1) and catalase (14.35 µg-1min-1) activities. Aloe vera @ 20% recorded highest reducing sugar (4.31%) and total sugar (7.67%) while untreated fruits reported the lowest one. Benzyl adenine @ 50 ppm recorded lowest acidity (0.33%) and highest chlorophyll content whereas benzyl adenine @ 100 ppm recorded lowest physiological loss in weight (12.33%).
