3.1 Introduction Vitamins are classically defined as a group of organic compounds required in very small amounts for the normal development and functioning of the body. They are not synthesised by the body, or only in insufficient amounts, and are mainly obtained through food (Machlin and Huni, 1994). There are thirteen vitamins: four are fat-soluble, namely vitamins A (retinol)

Introduction two categories: wheat, oats, rice and sorghum, of which about 7% of the entire crop in each case is used for industrial purposes, and barley, rye, (12-15%) is used industrially. The wor1dwide usage Of all the cereds’ gathered Sheets, is about 4% for seed, and the remainder almost equally shared between human food use (49%) and animal feed plus ‘processing and other’ (principally industrial) use (47%). The last cate￾gory divides into about 37% for animal feed plus

糖类化合物是自然界分布广泛、数量最多的有机化合物,是食品的主要组成 成分之一,也是绿色植物光合作用的直接产物。自然界的生物物质中,糖类化合 物约占3/4,从细菌到高等动物都含有糖类化合物,植物体中含量最丰富,约占 其干重的85%~90%,其中又以纤维素最为丰富。其次是节肢动物,如昆虫、蟹 和虾外壳中的壳多糖(甲壳质) 糖类化合物的分子组成可用Cn(H2O)通式表示,统称为碳水化合物
