荔波野生梅果实营养成分的测定和研究

目的]为开发利用荔波野生梅提供依据。方法]于茂兰国家级自然保护区内的洞塘乡随机采取荔波野生梅果实,观察其基本物理性状,测定其主要营养成分。结果]荔波野生梅果实的果形指数平均值为1.16,单果重低于国内主栽品种,含水量80.00%左右,可滴定酸含量为5.3%~6.8%,可溶性糖含量为1.1%~1.5%,糖酸比为0.19~0.24,蛋白质含量为0.53%~0.66%,Vc含量为3.29~4.51 mg/100 g,K含量是国内主栽品种的10倍以上,Ca含量为国内主栽品种的4~6倍,Na含量则远低于国内主栽品种。荔波野生梅果实的主要营养成分含量与国内主栽品种相当。结论]荔波野生梅是一种很有开发利用价值的食品资源,且具有良好的适应性。

Detection and Study on Nutrition Components of Wild Plum Fruit in Libo

Objective] The study was to provide the basis for the development and utilization of wild plum in Libo.Method] The basic physical characters of wild plum fruit in Libo randomly selected from Maolan national nature reserve in Tongtang township were observed and its main nutritional components were detected.Result] The average value of fruit shape index of wild plum in Libo was 1.16.Its single fruit weight was lower than that of domestic major cultivar.Its water content was about 80%,titratable acid content was 5.3%-6.8%,soluble sugar content was 1.1%-1.5%,sugar acid ratio was 0.19-0.24,protein content was 0.53%-0.66%,Vc content was 3.29-4.51 mg/100 g.Compared with the domestic major cultivars,K content was above 10 times higher,Ca content was 4-6 times higher,Na content was lower,the content of the main nutritional components of wild plum fruit in Libo were equivalent.Conclusion] Wild plum in Libo was a food resource with well development and utilization value,and had a good adaptability.
