| description | The study aims to evaluate the feasibility of using defatted <i>Tenebrio molitor</i> larvae proteins as substrates in microbial fermentation, targeting the development of high-value products to combat age-related health issues. Amid increasing demand for sustainable and nutrient-dense food sources, this study investigates the potential of extracts from <i>Tenebrio molitor</i> larvae as functional bioactive materials. Specifically, it compares the biological antioxidant activities of defatted <i>Tenebrio molitor</i> larvae extracts before (SMNFE) and after (SMFE) fermentation with <i>Saccharomyces cerevisiae</i>. Defatting removes lipids, while fermentation enhances the extract’s bioactivity. Biochemical analyses showed that SMFE had significantly higher total polyphenol (36.04 ± 1.04 μg GAE/mg) and flavonoid (12.69 ± 0.76 μg QE/mg) contents—over three times those of SMNFE. In addition, SMFE exhibited superior radical scavenging activity, reducing power, and electron-donating ability. The total amino acid content also increased by about 18% post-fermentation, with all measured amino acids except arginine showing elevated concentrations. These enhancements demonstrate the effectiveness of yeast fermentation in improving the nutritional and functional properties of insect-derived materials. The findings support the application of fermented insect extracts in medical foods and functional cosmetics, offering a promising direction for future bioconversion technologies. |
