新型食品营养源--火麻仁

New nutritional food source——hempseed

食用火麻仁已经有数千年的历史。近年来,开发火麻仁作为营养保健品已经有了一定的基础。火麻仁大约有25%～35%油脂、20%～25%蛋白质、20%～30%的膳食纤维,还含有丰富的维生素和矿物质。火麻仁油含(多)不饱和脂肪酸(PUFAs)超过80%,更重要的是,油脂中油酸(18:2omega-6)和α-亚麻酸(18:3omega-3),而且omega-6和omega-3ratio(n6/n3)的比例在2:1.2和3:1之间,这个比例对人体健康最合适,临床试验证明火麻仁油也是一种功能性油脂。另外,火麻仁的两种蛋白质为麻仁球蛋白和白蛋白,这两种植物储藏蛋白都是具备人体所有必需氨基酸而且容易消化的全价蛋白质,火麻仁蛋白质与其他食物蛋白质不同的是其高含量的精氨酸,可作为提高耐缺氧和改善贫血的良好功能性食品。同时,可作为调味品和酸奶配料,可方便补充蛋白质成分。

Hempseed typically contains 25%～30% oil , 20%～25% protein, 20%～30% dietary fiber, with rich vitamins and minerals. Hempseed oil is over 80% in polyunsaturated fatty acids （PUFAs）, and is an exceptionally rich source of the two essential fatty acids （EFAs） linoleic acid （18 ： 2 omega-6） and alpha--linolenic acid（18 ： 3 omega-3）. The omega-6 to omega-3 ratio （n6/n3） in hempseed oil is normally between 2 ： 1.2 and 3 ： 1, which is considered to be optimal for human health. Recent clinical trials have identified hempseed oil also as a functional food. In addition, the two main proteins in hempseed are edestin and albumin. Both of these high--quality storage proteins are easily digested and contain nutritionally significant amounts of all essential amino acids. Hempseed has exceptionally high levels of the amino acid arginine. , which can be improved hypoxia and anaemia.
