Chitosan nano-selenium hydrosol with immune enhancement effect and preparation, preservation and application

Abstract

The invention relates to the technical field of nano-selenium hydrosols, in particular to a chitosan nano-selenium hydrosol with an immune enhancement effect and preparation, preservation and application. The chitosan nano-selenium hydrosol with the immune enhancement effect comprises the following components in concentration: 0.5mmol/L-5.0mmol/L of nano-selenium and 100.0mg/L-1000.0mg/L of functionalized chitosan. The chitosan nano-selenium hydrosol with the immune enhancement effect has immune activity, and can increase the selenium content in muscle tissue of aquatic organisms including fishes and the like; and when the chitosan nano-selenium hydrosol is added into aquatic organism feed and serves as an immune enhancer for aquatic organisms, a more effective scheme can be provided for disease control of aquaculture. 本发明涉及纳米硒水溶胶技术领域，尤其涉及一种有免疫增强功效的壳聚糖纳米硒水溶胶及制备、保存和应用。该有免疫增强功效的壳聚糖纳米水溶胶含有以下浓度的组分：纳米硒0.5mmol/L～5.0mmol/L；功能化的壳聚糖100.0mg/L～1000.0mg/L。该有免疫增强功效的壳聚糖纳米硒水溶胶具有免疫活性，且可提高鱼类等水产生物肌肉组织中硒含量，将其加入水产生物饲料中作为水产免疫增强剂时，可为水产养殖病害防治提供一种更加有效的方案。
