In the present study, the carambola and celery pomace which are available in large quantity as byproducts in juice production were used to prepare insoluble fiber materials. Different micronization treatments such as ball milling, jet milling and high pressure micronization were applied to reduce the particle size of IFs to micron scale. Particle size reduction resulted in lowered bulk density, increased surface area, alternation in functional groups, and enhanced physiochemical properties such as emulsification capacity, swelling ability, solubility and cation-exchange capacity. Particle size changes therefore significantly affected the properties of different pomace IF samples.
中文摘要本研究以果汁加工的副产物-杨桃及芹菜果渣作为实验主材料，制备非水溶性纤维(insoluble fiber，IF)，经过不同的微化处理方式，如：(1)球磨破碎、(2)气动式喷射破碎及(3)高压破碎等，得不同微米大小的纤维微粒，随者粒径的降低，会使得纤维的体积密度变小，表面积增大，外观结构明显不同，纤维的官能基亦发生结构性的变化，理化性质诸如乳化力、膨润力、溶解度及阳离子交换能力皆因而提高，粒径大小显著影响果渣纤维的物理化学性质。
