Guava pulp was extracted from ripe fruits of cv. Sardar (L-49) by cold extraction method and treated with potassium sorbate and potassium metabisulphite (KMS) at 0.1% alone and in combination with heating at 85°C for 5 min. The pulp was packed in food grade plastic jars and stored at low temperature (2–5?°C) for three months. Addition of KMS in guava pulp showed better results than potassium sorbate in terms of less browning (NEB), retention of more ascorbic acid and good keeping quality.
