September 2020
To improve the industrial use of health-functional materials based on edible insects, the objective of this study was to establish optimal conditions for improving the quality of larval (PBSL) hydrolysates. PBSL was extracted using four methodologies: atmospheric pressure 50 °C-water extraction, atmospheric pressure 95 °C-water extraction, atmospheric pressure 50 °C-water enzymatic hydrolysis, and enzyme treatment under high pressure (HPE). The quality characteristics of soluble solid content, extraction yield, total protein content, protein yield, protein content with low molecular weight (LMW) (< 1kD), and the amino acid composition of hydrolysates were compared based on the different methods.

- UV exposure leads to increased reactive oxygen species and the production of matrix metalloproteinases, contributing to skin aging (photoaging).
- The study focused on testing a probiotic fermented plant extract (PELB) found in Kimchi for its potential anti-photoaging properties in skin cells exposed to UVB radiation.
- Results showed that PELB not only reduced elastase and collagenase activity but also increased collagen levels and antioxidant enzyme expression, indicating its potential as an effective ingredient in cosmetic products for UV-related skin protection.
