适宜晋中地区种植的彩色马铃薯品种营养品质分析与评价

In order to determine the nutritional quality of the two color potato varieties Hongmeigui and Heijingang, two color potato varieties suitable for cultivation in Jinzhong area were used as experimental materials with Holland No. 15 as the control. Their quality parameters (single potato weight, potato shape, skin color, flesh color, depth and number of bud eyes) and nutritional parameters (contents of dry matter, starch, soluble protein, anthocyanin, flavonoids and antioxidant capacity) were analyzed and evaluated. The results showed that the Hongmeigui showed red skinNutritional Quality Analysis and Evaluation of Color Potato Varieties Suitable for Planting in Jinzhong Area and red meat, and the Heijingang showed purple skin and purple meat. The single tuber weight of both of them was higher than that of Holland 15, and the number of bud eyes was less and the depth was shallow. The nutrient contents of the two potato varieties were significantly higher than that of Holland 15, and the contents of starch, anthocyanin, flavonoids and antioxidant capacity of Heijingang were higher than those of Hongmeigui. According to the comprehensive comparison, the two varieties of color potato suitable for planting in Jinzhong area have good quality and high nutritional value, and have a large space for development and utilization in enriching potato planting resources in Jinzhong area.
