AI Technical Summary

Technical Problem

In existing quinoa fermentation processes, quinoa husks are not effectively utilized, and the fermentation products lack oil-controlling, soothing, and antioxidant effects. Furthermore, there are risks of unstable microbial fermentation and contamination.

Method used

Quinoa hulls were enzymatically hydrolyzed using a mixture of α-amylase, neutral protease, and maltose amylase, followed by lactic acid bacteria fermentation to prepare quinoa hull fermentation products. The efficacy of these products was improved by controlling the enzymatic hydrolysis and fermentation conditions.

Benefits of technology

The fermented quinoa husk product significantly inhibits sebum secretion from sebaceous gland cells, exhibiting oil-controlling effects, inhibiting skin cell damage, and demonstrating significant soothing and antioxidant effects, thus improving the utilization rate of whole quinoa.
