中文摘要: 为了解新疆几种主栽桑葚果实的品质差异,筛选适合深加工的桑葚品种,选择南疆地区7个主栽桑葚品种为材料,对供试样品的水分、pH值、总糖、总酸、还原糖、总酚、总黄酮、原花青素等指标进行分析。结果表明:7种桑葚果实的理化成分存在显著差异(P<0.05),其中紫玉一号的水分含量最高89.62%;药桑的总酸含量最高1.86%;大白桑总糖、还原糖含量最高,分别为17.39%、8.58%;小黑桑的VC、粗脂肪、粗蛋白含量最高,分别为0.35 mg/g DW、2.83%和1.93%;而紫玉一号的总酚、总黄酮、原花青素含量最高,分别为17.09 mg GAE/g DW、12.46 mg RE/g DW和3.47 mg/g DW。综上所述,7个果桑品种营养成分丰富,其中大白桑的总糖含量最高,适合加工桑葚酒;小黑桑的粗脂肪粗蛋白含量最高,适用于膳食补充剂;紫玉一号总酚、总黄酮和原花青素含量最高,适合开发功能性食品。
Abstract:This study aimed to clarify the quality differences of fruits of main mulberry cultivars in Xinjiang and screen the cultivars suitable for deep processing.To be specific,the water content,pH,total sugar content,total acid content,reducing sugar content,total phenol content,total flavonoid content and procyanidins content in fruits of seven main cultivars in southern Xinjiang were analyzed.The results showed significant differences in the physico-chemical components of the fruits of the seven cultivars(P<0.05).Moreover,the analysis suggested the highest water content(89.62%)in fruits of Ziyu 1,total acid content(1.86%)in fruits of Yaosang,total sugar content(17.39%)and reducing sugar content(8.58%)in Dabaisang,VCcontent(0.35 mg/g DW),crude fat content(2.83%),and crude protein content(1.93%)in Xiaoheisang,and total phenol content(17.09 mg GAE/g DW),total flavonoid content(12.46 mg RE/g DW),and procyanidins content(3.47 mg/g DW)in Ziyu 1.To sum up,the fruits of the seven cultivars are rich in nutrients.Among them,fruits of Dabaisang with high total sugar content are applicable to the processing of mulberry wine.Fruits of Xioaheisang,which have the highest content of crude fat and proteins,can be used as dietary supplement.Fruits of Ziyu 1,with the highest content of total phenols,total flavonoids,and proanthocyanidins,is suitable for the development of functional food.
