摘要

苋是一种双子叶植物,现在被认为是一种促进健康的食物。全世界的食品工业都重新发现了它,他们越来越意识到苋在各种食品制剂中的许多用途和好处。对从面粉、蛋白质分离物和饮料中获得的Amaranth膳食纤维、可溶性和不溶性组分进行了物理化学表征,并评估了它们潜在的胆汁酸结合能力。初级胆汁酸与纤维结合可能有助于降胆固醇作用,而次级胆汁酸的结合可以最大限度地减少这些代谢产物对结肠的细胞毒性作用。苋纤维部分能够螯合胆酸盐、牛磺胆酸盐、脱氧胆酸盐和牛胆汁,其百分比不仅取决于所评估的苋纤维的来源和类型,还取决于所研究的胆汁酸。面粉纤维和分离蛋白不溶性组分对结合胆汁和胆汁酸最有效,其摄取值相对于消胆胺在29%和100%之间。此外,脱氧胆酸,一种疏水性的二级胆汁酸,被所有组分捕获最多,三种苋红产物的总纤维和不溶性纤维吸收率达到100%。这些结果表明,苋红纤维结合胆汁酸的主要作用对应于疏水相互作用介导的吸附作用。

Characterization and Bile Acid Binding Capacity of Dietary Fiber Obtained from Three Different Amaranth Products.

Amaranth is a dicotyledonous plant, now considered a health-promoting food. It has been rediscovered by the worldwide food industry, which is increasingly becoming aware of the many uses and benefits provided by amaranth in various food preparations. Amaranth dietary fibers, soluble and insoluble fractions, obtained from flour, protein isolate, and beverage were physicochemically characterized and their potential bile acid binding capacity was evaluated. Primary bile acids binding to fiber might contribute to a hypocholesterolemic effect, while the binding of secondary bile acids could minimize the cytotoxic effect that these metabolites exert on the colon. Amaranth fiber fractions were capable of sequestering cholate, taurocholate, deoxycholate, and bovine bile, with a percentage depending not only on the origin and the type of amaranth fiber evaluated but also on the bile acid studied. Flour fiber and the protein isolate insoluble fractions were the most efficient for binding bile and bile acids with uptake values between 29 and 100% relative to cholestyramine. Moreover, deoxycholate, a hydrophobic secondary bile acid, was the most captured by all the fractions, reaching 100% uptake with total and insoluble fibers of the three amaranth products. These results would suggest that the main effect through which amaranth fiber binds bile acids corresponds to an adsorptive effect mediated by hydrophobic interactions.

期刊介绍: Plant Foods for Human Nutrition (previously Qualitas Plantarum) is an international journal that publishes reports of original research and critical reviews concerned with the improvement and evaluation of the nutritional quality of plant foods for humans, as they are influenced by: - Biotechnology (all fields, including molecular biology and genetic engineering) - Food science and technology - Functional, nutraceutical or pharma foods - Other nutrients and non-nutrients inherent in plant foods
