摘要：目的研究鱼鳞制备物作为膳食纤维和食品包装纸的可行性。方法通过测定鱼鳞制备物对水、糖类、油脂吸附能力,研究鱼鳞制备物作为膳食纤维在食品及药品方面的应用；通过红外光谱和紫外光谱分析分析鱼鳞制备物的组成，通过电镜扫描测定鱼鳞制备物的外观形态，通过万能试验机测定鱼鳞制备物的最大应力，研究鱼鳞制备物在食品包装纸方面的应用。结果鱼鳞制备物的平均持水力为19。28g/g,平均持油力为23。17g/g,平均葡萄糖吸附力为43。54mg/g，60min时葡萄糖透析延迟指数为46，对水和油脂有较强的吸附能力,可以抑制人体对葡萄糖和油脂的吸收；由红外光谱可知鱼鳞制备物主要由蛋白质和羟基磷灰石组成，紫外光谱显示出鱼鳞制备物有高度有序的纤维晶体结构，电镜扫描显示出鱼鳞纸有较紧密的微观结构，最大应力的测试显示出鱼鳞纸有较大的物理强度。结论鱼鳞作为廉价的原料,可以较为容易地收集,经过一定的加工,作为膳食纤维加入到食品之中,可以起到吸附油脂,减少葡萄糖吸收的作用,有益于现代人的身体健康。鱼鳞制备物的纤维构造具有一定的强度，安全卫生可以制作食品包装纸。91510

Abstract;Purpose;To study the feasibility of fish scale product as dietary fiber, and to study the feasibility of making food packaging paper with fish scale product。 By measuring adsorption capacity of water, sugar, oil in fish scales, study the applications of scales in food and pharmaceutical。 Method; By measuring adsorption capacity of water, sugar, oil in fish scales, study the applications of scales product in food and pharmaceutical。 The feasibility of making food packaging paper with fish scale product was studied by scanning electron microscope and measuring maximum stress。Consequence; The water-holding power of fish scales product is

19。28 g/g, The oil-holding power of fish scales product is 23。17 g/g, for water and oil has strong adsorption ability, can inhibit the human body to absorb glucose。 Conclusion; Scales as cheap raw materials can be obtained easily。After certain processing, as a dietary fiber added to the food, it can play the role of oil absorption and reduce glucose absorption, which is beneficial to the health of modern people。 The fiber structure of scale product has certain strength, safe and hygienic, and can be used for making food packing paper。源G于J优L尔V论N文M网WwW.youeRw.com 原文+QQ75201`8766
