在控制测试质量条件下,测定了大骨节病区和非病区麦面、玉米面和黄豆中硒铜锌锰铁钙磷含量。对比分析结果表明:病区麦面中硒铜量低于、铁锰钙量高于、玉米面和黄豆中硒锌量低于非病区。在病区里,黄豆富含铜锌钙磷、钙磷比值较合理,麦面次之,玉米面较差。麦面的铜锌钙磷锰铁量随碾磨度由粗到精依次减少。病区村民常食的麦面(80—90%)—玉米面(10—20%)主食中,锰铁偏多、锌磷不足、硒铜钙缺乏,是一种无机元素较不平衡的食物。文末讨论了提高病区村民主食中缺乏元素供应水平的方法。
Under control test conditions, the contents of selenium, copper, zinc, manganese, manganese and phosphorus in the KBD and non-wedged wheat noodles, cornmeal and soybeans were determined. The results of comparative analysis showed that the selenium and copper content in wheat flour was lower than that in fermented wheat flour, the content of ferromanganese and calcium in corn flour was lower than that in non-disease area. In the ward, soybeans are rich in copper-zinc-zinc-phosphorus, calcium-phosphorus ratio is more reasonable, followed by wheat noodles, corn is poor. The surface area of copper, zinc, calcium, phosphorus and ferromanganese decreased with the degree of grinding from coarse to fine. Ward villagers often eat wheat noodles (80-90%) - cornmeal (10-20%) staple food, ferromanganese is too much, zinc and phosphorus deficiency, lack of selenium and copper calcium, is a less balanced inorganic elements of food. At the end of the article, we discussed how to improve the lack of supply of elements in staple foods of ward villagers.
