With a reduced particle size, the solubility of ultrafine powders increased significantly (P < 0.05), whereas the water holding and swelling capacities decreased with a reduced particle size and then increased. Fourier transform infrared spectroscopy analysis showed that ultrafine grinding did not damage the main cellular structure of GS powder.
The present literature review explores the energy-efficient ultrafine grinding of particles using stirred mills. The review provides an overview of the different …

1. Introduction. Diacylglycerol is a functional edible glyceride esterified by fatty acids at 1, 2 or 1, 3 hydroxyl groups of glycerol. DAG exists either as 1, 2-DAG or 1, 3-DAG (Miklos, Zhang, Lametsch, & Xu, 2013).As a by-product of the oil industry, DAG has been generally recognized as safe by the US Food and Drug Administration (FDA) (Morita & …
Ultrafine grinding is another method used to decrease grain flour particle size, while jet milling is an important alternative to the ultrafine grinding technique that is used to significantly reduce the flour particle size.
