摘　　要：先对橡实淀粉、橡实果仁和橡实果壳3种原料进行了理化分析,对研究中所采用3种原料的各个组分的含量具有初步的认知,以期为开发橡实资源的不同用途提供依据。研究发现橡实果仁中含有69.40%的淀粉,其中支链淀粉含量高达59.01%,单宁含量为8.34%;橡实淀粉原料的淀粉含量高达87.21%,其中支链淀粉含量高达68.56%,单宁含量为5.67%;除此之外,橡实果仁和橡实淀粉中还含有部分可溶性糖、粗脂肪、粗纤维和蛋白质。橡实果壳中含有大量的纤维素、半纤维素、木质素和单宁,其中综纤维素含量高达56.69%,酸不溶木质素含量为32.45%,In the thesis,we firstly optimized the design of physical and chemical analysis of acorn starch, acorn kernel and acorn hull raw materials, and obtained a rudimentary knowledge of component content of these three kinds of raw materials to provide a basis fur developing different usages. The results showed that acorn kernel contained 69.40 % starch content of which the amylopectin content was up to 59.01% ; the tannins content was 8.34 %. Acorn starch raw materials contained 87.21% starch content of which the amylopeetin content was up to 68.56 % ; the tannins content of acorn starch raw materials was 5.67 %. In addition, a certain amount of soluble sugar, crude fat, crude fiber, and proteins were also included in acorn kernel and acorn starch raw materials. Acorn hull contained a large amount of cellulose, hemieellulose,
