不同品种及大小规格桃果实营养品质及矿质元素差异分析OA

Fruit varieties and sizes are significant factors that influence consumer acceptance;however,few research has been conducted on the relationship between the nutritional quality of peaches and their varieties and sizes.This study focused on five main peach varieties produced in Jiangsu Province,China.Mature peach fruits were collected from the same orchard for each variety,and their nutritional quality and mineral element content across various varieties and sizes then compared.Results indicated that Zijinhong had the highest soluble solid content(12.27%),Xiacui exhibited the highest flavonoid content(0.24 mg·g-1),Baifeng had the highest vitamin C content(7.50 μg·g-1),and Jinling Huanglu demonstrated the highest total acid content(496.97 μg·g-1).Additionally,Xiacui had higher iron,boron,and zinc levels,Xiahui contained higher molybdenum levels,Zijinhong exhibited higher calcium and magnesium levels,and Baifeng generally had a low mineral content.For most of the varieties,medium-and small-sized fruits exhibited higher levels of vitamin C and most mineral elements,with medium-sized fruits demonstrating a higher soluble sugar content and small-sized fruits showing higher a flavonoid content.In summary,characteristic nutrient differences were observed among different varieties of peach fruits.In addition,compared to large-sized fruits,the medium-and small-sized fruits of most peach varieties had richer nutrient and mineral contents.The results of this study provide a scientific basis for the grading and quality evaluation of peach fruits.
