Variability in nutritional composition and phytochemical properties of red pitaya (Hylocereus polyrhizus) from Malaysia and Australia

Nurul S. R, . and Asmah R, . Variability in nutritional composition and phytochemical properties of red pitaya (Hylocereus polyrhizus) from Malaysia and Australia. pp. 1689-1697. ISSN 22317546

The present work sought to investigate the nutritional composition and phytochemical properties of red pitaya (Hylocereus polyrhizus) juices from Malaysia and Australia and to determine the optimum ethanol concentration (in the range of 0 “ 100 ethanol) for the extraction of phenolic flavonoid and betacyanin contents. The predominant macronutrient in red pitaya juice was carbohydrate while potassium and vitamin A were the major mineral and vitamin content. Red pitaya juice from Malaysia achieved optimal total phenolic content at 20 of ethanol (20 mL ethanol in 100 mL water v/v); total flavonoid content at 60 (v/v); and betacyanin content at 0 (v/v). Red pitaya juice from Australia achieved the maximum total phenolic content at 60 (v/v); total flavonoid content at 20 (v/v); and betacyanin content at 80 (v/v). Nutritional composition and the phytochemical properties of red pitaya in Malaysia and Australia were significantly different suggested the role of environmental factors like soil and climate on the phytochemical properties of red pitaya.

Abstract

The present work sought to investigate the nutritional composition and phytochemical properties of red pitaya (Hylocereus polyrhizus) juices from Malaysia and Australia and to determine the optimum ethanol concentration (in the range of 0 “ 100 ethanol) for the extraction of phenolic flavonoid and betacyanin contents. The predominant macronutrient in red pitaya juice was carbohydrate while potassium and vitamin A were the major mineral and vitamin content. Red pitaya juice from Malaysia achieved optimal total phenolic content at 20 of ethanol (20 mL ethanol in 100 mL water v/v); total flavonoid content at 60 (v/v); and betacyanin content at 0 (v/v). Red pitaya juice from Australia achieved the maximum total phenolic content at 60 (v/v); total flavonoid content at 20 (v/v); and betacyanin content at 80 (v/v). Nutritional composition and the phytochemical properties of red pitaya in Malaysia and Australia were significantly different suggested the role of environmental factors like soil and climate on the phytochemical properties of red pitaya.
