Abstract

There is a huge potential for dragon fruits grown in India but insufficient information may hamper its production and postharvest handling. The aim of this study was to investigate the right harvest time and maturity indices for red and white pulp dragon fruit. Growth and developmental studies were undertaken using destructive (total soluble solids (TSS), titratable acidity and TSS: acid ratio) and non-destructive methods (fruit weight, specific gravity, peel colour and heat units). Fruits were collected at seven intervals (7, 14, 21, 26, 31, 36 and 41 days after flowering) to assess the right maturity. All these methods were used to standardize the optimum maturity and right time for the harvest of red and white pulp dragon fruit. Harvesting dragon fruits between 31-36 days after flowering (DAF) was found ideal for optimum maturity and quality. Both red and white pulp fruits harvested at 31 DAF showed better quality in terms of physic-chemical and sensory attributes.
