Abstract

Dragon fruit skin has a very attractive red color that has the potential to produce anthocyanin pigments. Anthocyanin pigments are flavonoid compounds that are soluble in water and can be used as natural dyes in food and beverages. The purpose of this study was to see the effect of the number of multilevel extraction on the anthocyanin yield of dragon fruit peel extraction. 20 grams of dragon fruit peel powder with a mesh size of 20 was extracted in batches for 72 hours at room temperature using a mixture of distilled water and 10% citric acid (1:6) as a solvent. Variations in the number of stratified extractions were 1,2,3,4 and 5 times of extraction with the number of solvents respectively 500, 2 x 250 ml, 3 x 167 ml, 4 x 125 ml, and 5 x 100 ml. analysis of anthocyanin pigment levels using a spectrophotometer with a different pH method. The results obtained that the anthocyanin yield with samples 1 to 2 times of extraction increased by 6.35%, while the anthocyanin yield of samples 1 to 5 times of extraction increased by 35.65%. The highest yield of anthocyanin pigments was 4.1625 mg/20 grams in a multilevel extraction carried out for 5 times of extraction.

火龙果的果皮有一种非常吸引人的红色，有可能产生花青素色素。花青素色素是一种可溶于水的类黄酮化合物，可作为食品和饮料中的天然染料。研究多层提取次数对火龙果皮花青素得率的影响。以蒸馏水和10%柠檬酸(1:6)的混合物为溶剂，在室温下分批提取龙皮粉20克，孔径为20。分层提取次数的变化分别为1、2、3、4和5次提取，溶剂数分别为500、2 × 250 ml、3 × 167 ml、4 × 125 ml和5 × 100 ml。结果表明，提取1 ~ 2次样品的花青素得率提高了6.35%，提取1 ~ 5次样品的花青素得率提高了35.65%。经5次多级提取，花青素得率最高，为4.1625 mg/20 g。
