山葡萄是耐寒野生经济果树之一。东北地区已有大面积人工栽培,用以增加经济收入。山葡萄浆果紫黑色,是酿造优质山葡萄酒的“首选”原料。其红色素含量的多少直接影响山葡萄酒的色泽和质量。山葡萄色素大量存在于果皮中。不同品种(品系)的山葡萄浆果中,色素含量不同。从外观上难于判断果实色素含量的差异。因此,用国际食品农业组织(FAO)正式批准的色价法进行色素含量测定。目前,不同采收期山葡萄浆果中,色素含量变化的系统对比分析尚未见报道。为了
Mountain grape is one of the hardy wild economic fruit trees. Northeast China has a large area of artificial cultivation, to increase economic income. Mountain grape berry purple black, is the “preferred” raw material for making high-quality mountain wines. The amount of red pigment directly affects the color and quality of the mountain wine. Mountain grape pigment is abundant in the peel. Different varieties (strains) of mountain grape berry, pigment content is different. Judging from the appearance of the fruit pigment content differences. Therefore, with the Food and Agriculture Organization of the United Nations (FAO) officially approved by the color-price method for determination of pigment content. At present, the systematical comparative analysis of the pigment content in the berry of the grape in different harvesting periods has not been reported yet. in order to
