內(nèi) 容 簡(jiǎn) 介
殼聚糖是甲殼素脫去乙?；鶊F(tuán)后的物質(zhì)，又稱(chēng)脫乙酰甲殼素、幾丁聚糖、甲殼胺等。食品級(jí)殼聚糖采用深海阿拉斯加雪蟹殼為原料，100%無(wú)污染，安全可靠。
性狀：
外觀(guān)為灰白色，無(wú)毒、無(wú)味、有珠光色彩的片狀或粉狀固體，于185°C分解。不溶于水和一般有機(jī)溶劑，可溶于稀鹽酸、醋酸等多種無(wú)機(jī)酸和有機(jī)酸。
主要用途：
殼聚糖是自然界帶陽(yáng)離子的天然活性多糖，是繼蛋白質(zhì)、脂肪、糖類(lèi)、礦物質(zhì)、維生素以外的“人體第六生命要素’，可廣泛運(yùn)用在食品、醫(yī)藥、保健、化工等多個(gè)領(lǐng)域。
食品領(lǐng)域：可作為增稠劑，果蔬保鮮劑、果汁果酒澄清劑、中藥絮凝澄清劑、飲用水凈化劑、食品發(fā)酵液絮凝劑等。
醫(yī)藥、保健品領(lǐng)域：具有提高免疫力、降血脂、降血壓、調(diào)節(jié)血糖、抗衰老，改善酸性體質(zhì)等多種功能,并可用于膜材料和醫(yī)用材料等。
化工領(lǐng)域：
a.煙草領(lǐng)域：殼聚糖是性能良好的煙草薄片膠，具有改善口感，燃燒無(wú)毒無(wú)異味等特點(diǎn)。
b.輕紡領(lǐng)域：用于織物整理、保健內(nèi)衣等。
