壳聚糖
别名：甲壳胺;脱乙酰甲壳质;可溶性甲壳质;几丁聚糖;脱乙酰几丁质;聚氨基葡糖
脱乙酰度：85% 90% 95%
物化性质：壳聚糖（Chitosan），也称几丁聚糖，学名为β-1,4-聚-葡萄糖胺，由阿拉斯加深海雪蟹经脱钙、脱蛋白、 脱色、脱乙酰等工艺加工而成，有人体第六生命要素之美誉。
外观：食品级白色粉末，高密度的淡黄色粉末
壳聚糖的种类多，应用也多，其中在食品这一个行业就有很多的应用，具体的情况大家一起来看一下
1、做为食品中的抗菌剂。壳聚糖以及它的一些衍生物都具有很好的抗菌活性，能够有效一直一些细菌、真菌和病毒的生长繁殖。
而且它本身是无毒无害的，只使用一点就能达到非常好的效果，给食品的杀菌保险起到了非常重大的作用。
2、做为水果蔬菜的保鲜剂。水果蔬菜要想既保持它的口感，又要保证它们的营养，采取合理的保险手段非常重要，特别是对于那些需要长途运输的果蔬来说，保险工作就更加的重要了。
使用壳聚糖对涂抹保鲜，而膜层又具有很好的通透性和阻水性，有效抑制了果蔬的呼吸环境，减弱了了它们的呼吸代谢作用，同时水分的散失也大大降低，使得果蔬的营养价值和外观都得到了很好的保护。
3、抗氧化剂。肉类食品放久了往往会出现腐败变质的现象，使得肉制品的口味和营养都大大的损失了，使用了壳聚糖处理过的肉制品，其抗氧化能力大大的增强，如今很多肉制品的保险中能够都会用到壳聚糖。
4、果汁的澄清剂。果汁中含的维生素和和各种矿物质都比较多，存放久了经常会出现浑浊的现象，加入一定令的壳聚糖，能够有效避免这种现象的发生，使得果汁得到很好的净化，同时也保住了果汁的色泽和口感。

Chemical Property: By the Alaska deep snow crab through decalcification, deproteinization, decoloration, deacetylation process into human life, reputation as the sixth elements. Many kinds of application, also
Usage:
1, as antimicrobial agents in foods. Chitosan and its derivatives have good antibacterial activity, can have some bacteria, fungi and virus growth.
And it itself is harmless, use only a few can achieve very good results, to food sterilization insurance plays a very important role.

Fruits and vegetables to maintain its taste, but also to ensure that their nutrition, to take reasonable means of insurance is very important, especially for those in need of long-distance transportation of fruits and vegetables, insurance is more important.
To apply fresh use of chitosan, and the film has good permeability and water resistance, effectively inhibit the fruit and vegetable breathing environment, reduced the respiratory metabolism of them, at the same time, water loss is greatly reduced, so that fruits and vegetables nutrition value and appearance are well protected.
3, antioxidant. The meat is placed for a long time will often appear corrupt phenomenon, make meat taste and nutrition are greatly loss, the use of the meat products of chitosan treated, the antioxidant capacity greatly enhanced, now a lot of meat products in the insurance can have used chitosan.
4, fruit juice clarifying agent. Fruit juice contains vitamins and minerals are stored for a long time, often appear turbid phenomenon, the addition of chitosan must make, can effectively avoid the occurrence of this phenomenon, the juice purification is good, but also keep the fruit color and taste.
