报告题目：食品胶体营养学-透视食品与人体相互作用的新视角

报告摘要：

食品为典型的多分散相复杂体系，含有蛋白质、多糖、脂类等成分相互作用所形成的多尺度纳米颗粒。这颗粒不仅提供人体生命活动所必需的营养元素，也是食品结构骨架的物质基础。传统营养学研究认为，食品中的这些纳米颗粒只有被降解为小分子物质(如氨基酸、单糖、游离脂肪酸)后才能被细胞所吸收。针对完整食品纳米颗粒细胞吸收及胞内代谢行为相关研究鲜有报道。本课题组聚焦食品中多尺度纳米颗粒与细胞相互作用，跟踪其吸收过程并探究其胞内生物学效应，将相关研究定义为食品胶体营养学，对于开启食品与人体互作机制研究新思路具有重要意义。

TITLE：Colloidal Nutrition Science - A New Perspective to Understand Food-Body Interaction  

ABSTRACT：

Food is a typical complex system with multi-dispersed phases, which contains multi-scale nanoparticles formed by proteins, polysaccharides, and lipids. These particles not only provide essential nutrient elements for human life activities but also provide the material basis for the framework of food structure. According to traditional nutrition studies, these food nanoparticles can only be absorbed by cells after being degraded into small molecules (e.g., amino acids, monosaccharides, or free fatty acids). There are few reports on the cellular absorption and intracellular metabolic behavior of intact food nanoparticles. Our group focuses on the interaction between multi-scale food nanoparticles and cells, tracks their absorption process, and explores their intracellular biological effects. We coin the related research as “Colloidal Nutrition Science”, which is a new way of understanding the interaction mechanism between food and the human body.
