Storage and Quality Characteristics of Gryllus bimaculatus Powder Acorn Mook that Helps Sarcopenia

This study aims to evaluate the quality characteristics, antioxidant activity, and storage of acorn mook with Gryllus bimaculatus, which is reported to have excellent protein content. The storage and quality characteristics of acorn mook were analyzed. The proportions of Gryllus bimaculatus powder for each sample were set to 0%, 10%, 20%, and 30%. The pH of the acorn mook increased as the percentage of Gryllus bimaculatus powder increased, while the chromaticity of the acorn mook decreased in L-value, a-value, and b-value. As the percentage of Gryllus bimaculatus powder increased, the hardness, cohesiveness, springiness, gumminess, and chewiness decreased but adhesiveness increased. The final syneresis rate of acorn mook with 30% added Gryllus bimaculatus powder was controlled to around 10%, confirming its positive potential for storage and distribution. As the percentage of Gryllus bimaculatus powder increased, the total flavonoid content, total polyphenol content, ABTS and DPPH radical scavenging increased. The results showed that the addition of Gryllus bimaculatus powder to acorn mook enhances its storage stability and antioxidant activity, indicating its potential to mitigate sarcopenia caused by free radicals or oxidative stress. This research provides a basis for improving the storage stability and shelf life of acorn mook, which is beneficial for commercial distribution.
