棉酚(Gossypol)是一种黄色的毒性物质,主要存在于棉仁和棉根皮中。在棉籽压榨过程中,棉酚部分地溶入油中。棉酚在油中的含量随着制油工艺的优劣而不同。研究结果表明[①②],棉酚能刺激胃肠道粘膜、损害心肌、肝脏和肾脏等,而且能引起烧热病。一般认为长期食用含棉酚量高于0.03％的棉油对人的健康带来不良影响。目前农村社、队油厂加工的粗制棉油,棉酚含量一般都高于这个容许量,有的甚至高出几倍或几十倍。为了保障人民群众的健康,卫生人员需要对农村的食用棉油进行质量检查,社、队油厂也需要通过对棉酚含量测定来控制棉油制作的工艺条件,以提高棉油质量。鉴于上述原因,迫切需要建立棉油中棉酚的简易快速测定法。
Gossypol is a yellow, toxic substance found mainly in cotton bolls and cotton bolls. Gossypol partially dissolves into the oil during cottonseed crushing. The gossypol content in the oil varies with the quality of the oil refining process. The results show that [① ②], gossypol can stimulate the gastrointestinal mucosa, damage to the heart, liver and kidney, but also can cause fever. Generally believed that the long-term consumption of cotton oil containing more than 0.03% of cotton has a negative impact on human health. At present, the rural community, team oil processing crude cottonseed oil, gossypol content are generally higher than this allowance, and some even higher than several times or several times. In order to protect the health of the people, health workers need to carry out quality inspection of rural consumption of cottonseed oil, social and team oil plants also need to control the cottonseed oil production process conditions by gossypol determination to improve cottonseed oil quality. In view of the above reasons, there is an urgent need to establish a simple and rapid assay for the determination of gossypol in cottonseed oil.
