AFM为食品科学研究

使用原子力显微镜进行成像

原子力显微镜可以提供食品科学的独特数据。研究人员正在靠近天然条件的条件下观察分子的结构(例如明胶,酪蛋白,黄嘌呤多糖,果胶,直链淀粉和大豆蛋白)。还研究了较大的结构,例如多糖凝胶,淀粉,口香糖,巧克力和牛奶胶束。

AFM can provide high resolution images of small molecules and bigger structures. In food science, understanding the structure of foods such as chocolate can help improve the quality in terms of taste as a function of composition, additives, and processing variables. The unique ability of AFM to measure nanomechanical properties at the nanoscale can help distinguish different materials in blends. Samples can be investigated in air, at controlled humidity, or in a liquid environment. Finally, the effect of temperature can be investigated by heating or cooling the entire sample, or local thermal analysis can be used to probe phase transitions at the nanoscale.
