Abstract

With the evolving lifestyles and diets, natural bioactives with excellent nutritional value and specific health benefits are attracting increased attention. In this study, a bigel constructed by glycerol monolaurate (GML) and low acyl gellan gum (LA) was used as the co-delivery system to protect capsaicin (CAP) and gallic acid (GA). The results showed that CAP and GA in bigel exhibited higher stability than free ones. After 12 days at 4°C, the retention rates of CAP and GA in bigel were 71.13% and 83.34%, respectively, which increased by about 25.91% and 49.32% compared to that of free ones. In vitro digestion showed that the bigel exhibited significant controlled and sustained-release effects on CAP and GA. At the end of simulated intestinal digestion, >40% and 30% of CAP and GA were still not released from bigel. In the Caco-2 cell monolayers model, CAP and GA are mainly absorbed and transported by passive diffusion, and their bioavailabilities were increased by 1.35- and 1.77-fold compared to individually entrapped systems. Therefore, the stability and bioavailability of CAP and GA can be improved by co-encapsulating with GML-LA bigel.

Practical Application

Capsaicin (CAP) and gallic acid (GA) have multiple activities and are excellent bioenhancers. However, they are averse to application due to their low bioavailability. Bigel is an excellent co-delivery system that can effectively improve their bioavailabilities. In our previous study, based on monolaurate glycerides and low acyl gellan gum, a bigel with excellent properties was developed. This study further explored the effects of bigel on the stability, digestive release behavior and bioavailability of CAP and GA. Compared to free CAP and GA, bigel significantly improved their stability, achieved controlled release effects, and increased the bioavailability by 1.35 and 1.77 times, respectively. It provides a new perspective for the development of new functional foods.

Bigels作为辣椒素和没食子酸的共递送系统：控制释放和提高生物利用度

随着生活方式和饮食的不断发展，具有优异营养价值和特定健康益处的天然生物活性物质越来越受到人们的关注。本研究以单月桂酸甘油（GML）和低酰基结冷胶（LA）为共递送体系，对辣椒素（CAP）和没食子酸（GA）进行保护。结果表明，在bigel中，CAP和GA的稳定性高于游离体。在4°C条件下放置12 d， CAP和GA在bigel中的保留率分别为71.13%和83.34%，比游离菌分别提高了25.91%和49.32%。体外消化实验表明，bigel对CAP和GA具有显著的控释和缓释作用。在模拟肠道消化结束时，仍有40%和30%的CAP和GA未从bigel中释放。在Caco-2细胞单层模型中，CAP和GA主要通过被动扩散被吸收和运输，其生物利用度比单独包裹的体系提高了1.35倍和1.77倍。因此，与GML-LA bigel共包封可以提高CAP和GA的稳定性和生物利用度。辣椒素（CAP）和没食子酸（GA）具有多种活性，是优良的生物促进剂。然而，由于其生物利用度低，它们不适合应用。Bigel是一种优良的共给药系统，可有效提高其生物利用度。我们在前期的研究中，以单月桂酸酯甘油酯和低酰基结冷胶为原料，制备了一种性能优良的凝胶。本研究进一步探讨了毕格尔对CAP和GA的稳定性、消化释放行为和生物利用度的影响。与游离的CAP和GA相比，bigel显著提高了它们的稳定性，达到了控释效果，生物利用度分别提高了1.35倍和1.77倍。为新型功能食品的开发提供了新的视角。

期刊介绍： The goal of the Journal of Food Science is to offer scientists, researchers, and other food professionals the opportunity to share knowledge of scientific advancements in the myriad disciplines affecting their work, through a respected peer-reviewed publication. The Journal of Food Science serves as an international forum for vital research and developments in food science. The range of topics covered in the journal include: -Concise Reviews and Hypotheses in Food Science -New Horizons in Food Research -Integrated Food Science -Food Chemistry -Food Engineering, Materials Science, and Nanotechnology -Food Microbiology and Safety -Sensory and Consumer Sciences -Health, Nutrition, and Food -Toxicology and Chemical Food Safety The Journal of Food Science publishes peer-reviewed articles that cover all aspects of food science, including safety and nutrition. Reviews should be 15 to 50 typewritten pages (including tables, figures, and references), should provide in-depth coverage of a narrowly defined topic, and should embody careful evaluation (weaknesses, strengths, explanation of discrepancies in results among similar studies) of all pertinent studies, so that insightful interpretations and conclusions can be presented. Hypothesis papers are especially appropriate in pioneering areas of research or important areas that are afflicted by scientific controversy.
