Sesaminol triglucoside (STG), the most abundant lignan glycoside existing in sesame cake/meal, has exhibited various biological activities. However, little information about its in vitro fermentation with intestinal microbiota is available. Therefore, the effect of STG from sesame cake on the fermentation of human fecal microbiota was evaluated. First, high-purity STG was successfully prepared from defatted sesame cake by extraction with 80% ethanol and simple purification procedures of polyamide column chromatography and Toyopearl HW-40S column chromatography. Then the influence of STG on intestinal microbiota was conducted by monitoring bacterial populations and analyzing the concentrations of short-chain fatty acids (SCFA). We found that STG could significantly induce an increase in numbers of Lactobacillus–Enterococcus group and Bifidobacterium in fermentation in vitro with human fecal microbiota, while it did not stimulate the bacterial growth of Eubacterium rectale–Clostridium coccoides group, Clostridium histolyticum group, and Bacteroides–Prevotella group. Furthermore, it was found that concentrations of formic, acetic, propionic, and butyric acids in STG culture increased significantly during the fermentation, and its total SCFA concentration was relatively higher than those of the control and glucose cultures at 6 and 12 h fermentation. Our findings provided further evidence for the importance of human intestinal bacteria in the bioactivity of STG and its metabolites in the maintenance of human health.

BACKGROUND Sesame meal, characterized by high moisture, viscosity and oxidative instability, presents utilization challenges and is frequently relegated to farmland fertilizer – a practice that underutilizes its rich protein content. METHODS This study developed three types of soy sauce using sesame meal supplemented with soybeans. For the first time, a dual-strain co-fermentation system employing Aspergillus oryzae 3.042 and Aspergillus niger AS3.350 was applied to sesame meal. The dynamic evolution of taste and volatile flavor compounds during fermentation was systematically analyzed via electronic tongue technology and gas chromatography–mass spectrometry. The sesame meal soy sauces were benchmarked against four commercial premier-grade products, with flavor profiles evaluated using principal component analysis and orthogonal partial least squares discriminant analysis. Notably, the physicochemical indices of the sesame meal soy sauce complied with Chinese premier-grade standards. RESULTS The dual-strain-fermented soy sauce demonstrated outstanding flavor complexity, sweetness and richness, achieving parity with premier-grade soy sauce. Notably, it contained 2,3,5-trimethylpyrazine and 3-hydroxy-2-butanone, key compounds imparting distinctive roasted grain and creamy flavors, which collectively defined its unique sensory profile. Conclusion This research significantly elevates the utilization value of sesame meal while establishing a viable pathway for its commercial adoption in soy sauce production. © 2025 Society of Chemical Industry.

This is the first study that explores blending polylactic acid (PLA) with various biomasses, including food wastes─brewer’s spent grain (BSG), spent coffee grounds (SCG), sesame cake (SC), and thermoplastic starch (TPS) biomass to create composite gastric floating drug delivery systems (GFDDS) through 3D printing. The aim is to investigate the influence of biomass percentage, biomass type, and printing parameters on their corresponding drug release profiles. 3D-printed (3DP) composite filaments were prepared by blending biomasses and PLA before in vitro drug release studies were performed using hydrophilic and hydrophobic model drugs, metoprolol tartrate (MT), and risperidone (RIS). The data revealed that release profiles were influenced by composite compositions and wall thicknesses of 3DP GFDDS capsules. Up to 15% of food waste could be blended with PLA for all food waste types tested. Delivery studies for PLA-food wastes found that MT was fully released by 4 h, exhibiting burst release profiles after a lag time of 0.5 to 1.5 h, and RIS could achieve a sustained release profile of approximately 48 h. PLA-TPS was utilized as a comparison and demonstrated variable release profiles ranging from 8 to 120 h, depending on the TPS content. The results demonstrated the potential for adjusting drug release profiles by incorporating affordable biomasses into GFDDS. This study presents a promising direction for creating delivery systems that are sustainable, customizable, and cost-effective, utilizing sustainable materials that can also be employed for agricultural, nutraceutical, personal care, and wastewater treatment applications.
