Content Analysis of Sugar, Acid and Vc in the Fruit of Different Peach Varieties

doi:10.11923/j.issn.2095-4050.cjas16120019

Abstract

Abstract: To understand the characteristics of sugar, acid and Vc in fruits of different peach varieties, and compare the composition and content of sugar, 16 peach varieties with different types and different mature periods were collected to determine the content and composition of sugar, acid and Vc in fruits, and study and compare the differences and characteristics among different peach germplasms. The results indicated that the soluble sugar of peach fruit was mainly composed of sucrose, fructose, glucose and sorbitol, with an average content of 78.81 mg/g of sucrose as the highest, and peach fruit could be classified into sucrose accumulation model. The titratable acid content varied with different types of peach varieties, and that of nectarine were significantly higher than that of wild peach, the former could be 1.6 times of the latter, whereas the Vc content of different types of peach varieties was not significantly different. Due to the differences of sugar composition and the content of sugar and acid in fruits among different peach varieties, their flavor showed distinctive features.
