Abstract

Problem statement: Dragon fruit (Hylecereus polyhizus) is well known for the rich nutrient contents and it is commercially available worldwide for improving many health problems. Several studies show the proximity value of red pitaya fruits but the nutrient composition of the stem has not been extensively studied. Approach: This study was carried out to measure the proximate analysis of moisture content, water activity, ash, crude protein, crude fat, crude fiber, glucose and ascorbic acids content in premature and mature of dragon fruit. The dried powder was produced from the stem of dragon fruit and the proximate analysis of dragon fruit stem was compared between freeze drying process and drying oven process. Results: Results of this study showed that 96% moisture; 0.270 g of protein; 0.552 g L-1 glucose and 132.95 mg L-1 ascorbic acid of dragon fruit stem found higher than the fruit flesh of the dragon fruit. Conclusion: The premature stem had higher values than the mature stem of the dragon fruit which may helpful in preventing the risk factors of certain diseases.
