Abstract
|
|
|
The purpose of this study was to confirm the skin whitening and UV absorption effects of bioconverted Beta vulagaris (BBE) using Lactiplantibacillus plantarum SM4, and the effects were evaluated by measuring total polyphenol content (TPC), total flavonoid content (TFC), radical elimination activity (RSA), and tyrosinase activity inhibition (TAI).
TPC and TFC of BBE were 25.0 mg GAE/g DM and 8.05 mg QE/g DM, which were 1.3 and 1.1 times higher than hot-water extract (HWE) respectively. RSA, an indicator of antioxidant activity, and TAI, an indicator of skin-whitening effect, were 36.8%, and 68.6%, respectively, 1.1 and 1.2 times higher than that of HWE. UVA and UVB absorption of BBE were 21.4 and 87.6%, which was 1.4 and 1.7 times higher than that of HWE respectively. When main substances of BBE were analyzed using LC-MS/MS, kaempferol and isorhamnetin, a type of polyphenols known to have high antioxidant and skin-whitening effects, were identified. As a results, BBE is expected to be used as a functional cosmetic material as it has excellent antioxidant, skin whitening, and UV absorption properties.
