全谷物饮品稳定性的多尺度表征方法

随着全谷物健康认知和科学饮食概念的普及,消费者越来越关注形式各异的全谷物食品。全谷物饮品作为全谷物食品中的一种重要产品形式,其物理稳定性是研究开发过程中面临的主要挑战。由于全谷物饮品是一种以水为连续相,以淀粉、膳食纤维、蛋白质等为分散相的多相浊状液热力学不稳定体系,其分离速度快,严重影响消费者的可接受度。通过文献梳理,总结了全谷物饮品稳定性的宏观、介观、微观、纳观等多尺度表征方法及特征化学组分的表征方法,期望能为全谷物饮品的开发提供方法指导,特征化学组分助力全谷物食品的快速发展。

Multiscale characterized methods for the stability of whole grain drink

With the popularization of the concepts of whole grain health cognition and scientific diet, consumers are paying more and more attention to different forms of whole grain food. Whole grain drink is one of the important products made from whole grain, and the physical stability of whole grain drink is a major challenge in the process of research and development. Since whole grain drink is a thermodynamically unstable system of multiphase turbidite liquid with water as the continuous phase and starch, dietary fiber, protein as the dispersed phase, the separation speed of whole grain drink is fast, which seriously affected the acceptability of consumers. Based on literature review, the multiscale characterization methods of macroscopic, mesoscopic, microscopic and nano-scale for the stability of whole grain drink and characterization methods of the characteristic chemical components were summarized. This paper summarized the stability of whole grain drink characterized with multiscale methods, which could provide methodological guidance for the development of whole grain drink and facilitate the rapid development of whole grain foods.
