玉米所含尼克酸,主要为结合型式,未经分解,不能为动物机体所利用[1,2]。于志深等[3]曾报告以玉米为主食的个别地区,仍有原发性赖皮病发生,这表明尼克酸缺乏是玉米主食地区尚未完全解决的问题。Kodicek等[3-6]认为玉米经石灰水或氢氧化钠溶液处理后,其所合结合尼克酸可以获得释放,且可为动物所利用。Laguna等[7]及Squibb等[8]也获得了类似的秸果。但是,Krehl等[9]未观察到玉米经用石灰处理后所制的薄饼具有任何促进大白鼠生长的作用,Goldsmith等[10]给四名成年女子每日食用玉米80克,也未见到用石灰水处理玉米在改进人体尼克酸营养方面的效果。Pellitt和Platt[11]认为石灰水处理玉米在营养上具有缺陷,它使玉米中乙族维生素遭受较严重的损失。因此,设法提高
Nickel acid contained in corn, mainly for the combination of type, without decomposition, can not be used for animal body [1,2]. Yu Zhishen et al. [3] reported that there are still some cases of primary dermatosis in some areas where maize is the staple food. This indicates that the lack of niacin is a problem that has not yet been completely solved in the staple food area of maize. Kodicek et al. [3-6] concluded that maize could be released after it was treated with lime water or sodium hydroxide solution and could be used by animals. Similar results have also been obtained by Laguna et al. [7] and Squibb et al. [8]. However, Krehl et al. [9] did not observe any effect of the pancake made from lime treated corn on the growth of rats. Goldsmith et al. [10] did not eat 80 grams of corn daily for four adult women Effect of Treating Corn with Lime Water in Improving Nutrients in Human Niacin. Pellitt and Platt [11] considered that lime-water treated maize has nutritional deficiencies that cause severe losses of vitamin B in corn. So try to improve
