This study determines the effect of cookies made from sea grapes (Caulerpa racemosa) on PGC-1α, total cholesterol, and blood glucose levels on mice fed with a Cholesterol- and Fat-Enriched Diet (CFED). The antioxidant activity, tyrosinase inhibition, α-glucosidase, and α-amylase inhibition is also analyzed in order to assess the in vitro anti-aging potential of sea grapes cookies. Forty male Mus muscullus albino mice weighing 20 g–30 g were used and randomly distributed into four groups of ten animals each. Group A served as a normal control (given a standard dry pellet diet), Group B was given CFED only, and mice in Groups C and D were given CFED with 100 mg and 200 mg/20 g body weight of sea grapes cookies, respectively for 4 weeks. In vitro study shows that the percentage of inhibition activity of antioxidant, L-Tyrosine, L-Dopa, α-glucosidase, and α-amylase inhibition were 45.65 ± 1.50, 8.95 ± 0.06, 21.31 ± 0.98, 77.12 ± 4.67 and 70.94 ± 0.98, respectively. This study found that group D had better activity in lowering blood glucose than group C (p < 0.0001). In addition, although there was not found significant difference between groups C and D in blood cholesterol reduction and PGC-1α (p = 0.1482), both groups experienced the same effect in total cholesterol reduction and PGC-1α in mice (significantly, p < 0001). Thus, we conclude that sea grapes cookies are proven to improve PGC-1α, total cholesterol, and blood glucose levels in mice fed with CFED. Hence, sea grapes cookies is a potential anti-aging novel-functional food.

AIM: This study aims to evaluate the nutritional content and physicochemical aspect of the combination of eel and tempe flour. METHODS: Samples of swamp eel and tempe flour were combined in a ratio of 1:1 (A), 1:2 (B), 1:3.5 (C), and 1 kilogram of Asian swamp eel meat without additional tempe (D), respectively. Homogenization was done using a sinmag planetary mixer. The sample analysis was performed at the SIG Laboratory (PT. Saraswanti Indo Genetech) on November 16, 2021. The samples were analyzed triple (triplicates). Statistical analysis was performed using GraphPad Prism version 9.3.0 for Mac OS. Variables were analyzed using multivariate ANOVA with 95% CI (0.05). RESULTS: There was a significant difference between Samples A, B, C, and D for every proximate analysis parameter (p = 0.000) p < 0.05. The results showed a significant difference in the unsaturated fatty acid parameter between the groups (p < 0.001). Sample C has the highest B9 (folic acid) content compared to other samples (1258.53 ± 1.39 mcg/100 g) and a significant difference was found between samples (p < 0.0001). CONCLUSION: Tempe flour enriched eel flour can act as a source of folate, due to its high folate content. Tempe flour enriched eel flour could be used as a flour mixture in any food products that require flour to increase folate content.
