Supercritical mixed pectin coating process for improving stress resistance of probiotics

The invention relates to the technical field of microbial preparations, in particular to a supercritical mixed pectin coating process for improving stress resistance of probiotics. The supercritical mixed pectin coating process comprises the following steps: adding a probiotic product and a pectin coating agent into a supercritical carbon dioxide device, and carrying out supercritical carbon dioxide dissolving and mixing, so that pectin and the probiotic product are fully mixed, and finally, a pectin coated probiotic product is obtained. The supercritical carbon dioxide dissolving and mixing technology is adopted, the negative effects of uneven coating and easy agglomeration of probiotic products are effectively avoided, and due to operation in a low-temperature environment, the probiotics are not damaged, the activity of the probiotics can be ensured, and the stress resistance of the probiotics is improved. 本发明涉及微生物制剂技术领域，具体涉及一种提高益生菌抗逆性的超临界混合果胶包被工艺。所述超临界混合果胶包被工艺为将益生菌产品与果胶包被剂加入超临界二氧化碳装置中，进行超临界二氧化碳溶混，使果胶与益生菌产品
