Analysis of the Mineral Elements and Organic Acid Contents of Shuijing Honey Pomelo and Sanhong Honey Pomelo
摘要
Abstract
To analyze the mineral element content,organic acid composition,and organic acid content of Shuijing honey pomelo and Sanhong honey pomelo—two main cultivated varieties of honey pomelo in Hainan—this study aims to provide a theoretical reference for honey pomelo production,cultivation,nutritional evaluation,and quality regulation.The mineral ele-ments in the fruits were determined via atomic absorption spectrometry and colorimetry.However,the composition and content of organic acids in the fruits were analyzed via high-performance liquid chromatography(HPLC).Both Shuijing honey pomelo and Sanhong honey pomelo fruits were rich in mineral elements,including P,K,Ca,Mg,Fe,Mn,Zn,and Cu.Among these elements,those with relatively high contents in Shuijing honey pomelo were P(6.79 mg·g‒1),K(0.50 mg·g‒1),Ca(439.09 μg·g‒1),and Mg(404.48 μg·g‒1).For Sanhong honey pomelo,the mineral elements with relatively high contents were P(6.13 mg·g‒1),K(0.46 mg·g‒1),Ca(747.41 μg·g‒1),and Mg(596.83 μg·g‒1).A total of 12 organic acids were identified in the two honey pomelo varieties,with citric acid and succinic acid being the dominant organic acids.The total acid content was 8 236.93 μg·g‒1 for Shuijing honey pomelo and 8 262.36 μg·g‒1 for Sanhong honey pomelo.Specifically,citric acid and succinic acid accounted for 72.82%and 6.58%of the total acid in Shuijing honey pomelo,respectively;in Sanhong honey pomelo,these two acids accounted for 74.71%and 6.92%of the total acid,respectively.In conclusion,both Shuijing honey pomelo and Sanhong honey pomelo fruits are rich in mineral elements such as P,K,Ca,and Mg.Citric acid is the main organic acid,followed by succinic acid.There are differences in the contents of mineral elements and organic acids between the two varieties.关键词
