AI Technical Summary

Technical Problem

Current probiotic delivery systems have low survival rates when facing harsh environments such as stomach acid and digestive enzymes, short intestinal retention time, and lack effective mucosal adhesion, resulting in weakened therapeutic effects.

Method used

A high internal phase emulsion system with synergistic stability of egg yolk particles and salted duck egg white is used, combined with the acid buffering capacity of eggshell powder, to construct a multi-scale protective structure, including interface stability, continuous phase network and chemical buffering, forming a multi-scale protection with dense interface layer, continuous support network and local chemical buffering.

Benefits of technology

It significantly improves the survival rate and intestinal retention capacity of probiotics in the gastrointestinal tract, enhances their colonization ability in the intestine, prolongs their residence time in the stomach, improves storage stability, and increases the number of live bacteria by six orders of magnitude after simulated gastrointestinal digestion.

Abstract

本发明公开了一种用于益生菌递送的高内相乳液的制备方法,属于益生菌递送系统技术领域。该方法通过咸鸭蛋清盐诱导解聚蛋黄颗粒,优化其界面性能,形成致密界面屏障(第一重保护);两者共同构建凝胶网络,提供整体结构支撑与滞留(第二重保护);蛋壳粉在凝胶网络中作为“微型缓冲站”,原位中和胃酸,创造局部友好微环境(第三重保护)。这三者有机结合,最终实现了从“被动屏蔽”到“主动缓冲”、从“局部保护”到“系统支撑”的全面提升,从而达成了显著提高益生菌胃肠道存活率并增强其肠道滞留能力的核心发明目的。
