The effects of superfine grinding on the physicochemical and functional properties of asparagus pomace were investigated. The results showed that in terms of the specific surface area, water solubility, soluble dietary fiber content, and ratio of insoluble dietary fiber to soluble dietary fiber, finer samples usually possessed better physicochemical properties compared with coarse samples. However, grinding samples excessively to produce small particle sizes could reduce the water-holding capacity, oil-binding capacity, and swelling capacity. In addition, the extraction of both free and bound phenolics in asparagus pomace powder samples and the samples' absorption of both nitrite ion and glucose showed typical bell-shaped curves, demonstrating that superfine grinding could significantly impact the various properties of asparagus pomace. This study should provide insights into the effect of micronization on the functionalities of fiber-rich food materials. PRACTICAL APPLICATION: This article deals with the effects of superfine grinding on the physicochemical and functional properties of asparagus pomace. The results showed that the properties of asparagus pomace did not always improve gradually with decreasing particle size. With a decrease in granularity, some parameters showed a bell-shaped curve whereas others initially increased and then stabilized, indicating that in actual production, the crushing particle size should be determined according to actual needs or target parameters.

超细粉碎对芦笋果渣的影响。第一部分：物理化学和功能特性的变化

研究了超细粉碎对芦笋渣理化和功能特性的影响。结果表明，在比表面积、水溶性、可溶性膳食纤维含量和不溶性膳食纤维与可溶性膳食纤维的比例方面，较细的样品通常比粗样品具有更好的理化性质。然而，过度研磨样品以产生小粒径会降低持水能力、油结合能力和溶胀能力。此外，芦笋渣粉末样品中游离和结合酚类物质的提取以及样品对亚硝酸根离子和葡萄糖的吸收均呈现典型的钟形曲线，表明超细研磨可以显着影响芦笋渣的各种性质。这项研究应该提供关于微粉化对富含纤维的食品材料功能的影响的见解。实际应用：本文讨论了超细研磨对芦笋渣理化和功能特性的影响。结果表明，芦笋果渣的特性并不总是随着粒径的减小而逐渐改善。随着粒度的减小，有的参数呈钟形曲线，有的先增大后趋于稳定，说明在实际生产中，破碎粒度应根据实际需要或目标参数确定。本文介绍了超细研磨对芦笋渣理化和功能特性的影响。结果表明，芦笋渣的特性并不总是随着粒径的减小而逐渐改善。随着粒度的减小，有的参数呈钟形曲线，有的先增大后趋于稳定，说明在实际生产中，破碎粒度应根据实际需要或目标参数确定。本文介绍了超细研磨对芦笋渣理化和功能特性的影响。结果表明，芦笋果渣的特性并不总是随着粒径的减小而逐渐改善。随着粒度的减小，有的参数呈钟形曲线，有的先增大后趋于稳定，说明在实际生产中，破碎粒度应根据实际需要或目标参数确定。
