ABSTRACT
Phenol-pyranoanthocyanins, a structurally modified type of anthocyanin, has higher stability than anthocyanins. However, their conversion occurs slowly. Therefore, it is crucial to improve the conversion efficiency and production of pyranoanthocyanins. In this study, cranberry anthocyanin (CRAN) was fermented using two Lactobacillus strains along with caffeic acid to form cranberry-derived pyranoanthocyanins (PY-CRAN). PY-CRAN was characterized and identified. The physicochemical properties, antioxidant activity, and tyrosinase inhibitory capacity of PY-CRAN were assessed. The results showed that phenol-pyranoanthocyanins can be rapidly produced through fermentative transformation using Lactiplantibacillus plantarum and Lacticaseibacillus paracasei. Lacticaseibacillus paracasei exhibits a higher propensity for producing phenol-pyranoanthocyanins. PY-CRAN exhibits high stability under light and various pH conditions. Moreover, they possess excellent antioxidant properties and the ability to inhibit tyrosinase. These results suggest that fermentative biotransformation conducted by Lactobacillus is an ideal method for producing cranberry pyranoanthocyanins. The resulting anthocyanins have potential as antioxidant and whitening agents, making them promising bioactive ingredients.
