Abstract

The tomato pomace obtained during processing as a residue of tomato processing from large industry. The interactions between tomato pomace and fecal bacteria, bile acids during in vitro digestion were studied. Digestion was carried out by using bioreactor in anaerobic conditions. Tomato pomace can significantly affect the count of fecal bacteria and the solubility of bile acids in in vitro digestion due to bonding ability of their proteins/peptides. The availability and use of bile acids does not only depend on the interactions between bile acids and bacteria, but also the interactions of bile acids with digested food components. Tomato pomace characterized high dietary fiber content and its fractions: 17.64-21.53% for cellulose and 13.48-18.63% for lignin. Given our results we supposed that fecal bacteria can use primary bile acids, as their source of energy in an environment where carbon availability is limited.

摘要

番茄渣是大型工业番茄加工过程中产生的残留物。研究了番茄渣与粪便细菌、体外消化过程中胆汁酸之间的相互作用。使用生物反应器在厌氧条件下进行消化。由于其蛋白质/肽的结合能力，番茄渣在体外消化中可显著影响粪便细菌数量和胆汁酸的溶解度。胆汁酸的可用性和利用不仅取决于胆汁酸与细菌之间的相互作用，还取决于胆汁酸与消化后的食物成分之间的相互作用。番茄渣的膳食纤维含量及其组分特征如下：纤维素为17.64 - 21.53%，木质素为13.48 - 18.63%。根据我们的研究结果，我们推测在碳源有限的环境中，粪便细菌可以利用初级胆汁酸作为其能量来源。
