Background and aimsA combined eel and soy-based tempe (CEST) flour is rich in nutrients, especially its high amino acid content in which bioactive peptides (BPs) are expected to be found. Hence, this research aimed to identify the BPs of CEST flour and CEST supplementation’s effect on improving nutritional status biomarkers by ameliorating serum protein, hemoglobin, and IGF-1 of malnourished rats.MethodsCEST flour with a ratio of eel and soy-based tempe of 1:3.5 was produced by applying the oven drying method. Amino acid sequences from six BPs were analyzed using a protein sequencer and spectrometer-electrospray ionization (MS-ESI). A total of thirty malnourished male Rattus norvegicus aged 3–4 weeks were given low-protein (LP; 4% w/w protein) diet treatment for 4 weeks. Afterward, rats were divided into 3 groups of 10 rats. Group A and B remained on a low-protein diet for 4 weeks, receiving an LP diet and getting doses of CEST of 100 and 200 mg/kg BW, respectively, via oral. Group C or control was given a Normal-protein (NP) diet (23% w/w of protein) and was allowed to feed ad libitum during the trial period without a dose of CEST.ResultsSix bioactive peptides were found, with WMGPY being the most abundant, along with a DPPH radical scavenging activity of 5.0 mg/mL. The results showed that serum protein, hemoglobin, and IGF-1 of group B were significantly higher compared to groups A and C (p = 0.0021). CEST dose of 200 mg/kg BW was more effective to increase serum levels of protein (p = 0.0052), hemoglobin, and IGF-1 (p < 0.0001) compared to a 100 mg/kg BW dose.ConclusionThis indicates that the CEST flour has six bioactive peptides, which may contribute to the improvement of nutritional status biomarkers. To establish its potential impact, a human clinical study is urgently needed.

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.

Background: Developing countries need funding for researchers to maximize the evidence base, especially in stunting research. This short policy is expected to provide opportunities for Indonesia to receive more research funding to stunt philanthropists. Policy and implications: Multi-sector cooperation is arguably the leading player in acceleration programs to reduce growth delays. The Stunted Reduction Acceleration Program, complemented by higher research and development expenditures (RDEs) and open policies to support philanthropic activities in Indonesia, will help improve the efficiency of stunted stunt reduction through adequate funding and investment. As evidenced by Singapore and Thailand, the increase in government budgets focused on research and development (R&D) and supportive environments, as shown by Global Philanthropy Environment Index (GPEI), prove that evidence-based and practical researches can lead to the reduction of estimated prevalence of stunting rather than innovation-stage research. Recommendations: Attention needs to be directed in proposing major changes in law and policy which regulate the allocation of research-development expenditure, which will initiate the creation of a supportive environment for philanthropy acts regarding stunting. The challenges associated with these issues are: (1) Stunted research and innovation are still left behind, (2) The availability of data and the lack of transparency, (3) Subpar performance in relation to philanthropists, (4) Inconsistent legal definitions and a lack of industry-specific guidelines, (5) Inadequate law enforcement, (6) Local leaders must engage in evidence-based advocacy, (7) Philanthropists have limited opportunities to learn.
