Exogenous enzymes are extraneous enzymes that are not intrinsic to the subject. The exogenous enzyme industry has been rapidly developing recently. Successful application of recombinant DNA amplification, high-efficiency expression, and immobilization technology to genetically engineered bacteria provides a rich source of enzymes. Amylase, cellulase, protease, pectinase, glycosidase, tannase, and polyphenol oxidase are among the most widely used such enzymes. Currently, the application of exogenous enzyme technology in the development of natural plant resources mainly focuses on improving the taste and flavor of the product, enriching the active ingredient contents, deriving and transforming the structure of a chosen compound, and enhancing the biological activity and utilization of the functional ingredient. In this review, we discuss the application status of exogenous enzyme technology for the development of natural plant resources using typical natural active ingredients from plant, such as resveratrol, steviosides, catechins, mogrosides, and ginsenosides, as examples, to provide basis for further exploitation and utilization of exogenous enzyme technology.

外源酶是非受试者固有的外来酶。外源酶产业近来发展迅速。重组DNA扩增、高效表达和固定化技术在基因工程细菌中的成功应用提供了丰富的酶源。淀粉酶、纤维素酶、蛋白酶、果胶酶、糖苷酶、鞣酸酶和多酚氧化酶是最广泛使用的此类酶。目前外源酶技术在天然植物资源开发中的应用主要集中在改善产品的口感和风味，丰富有效成分含量，衍生和改造所选化合物的结构，提高生物活性和利用。的功能成分。在这次审查中，
