This research emphasizes the application of ultrafine grinding technologies to optimize the extraction process of chitin from house crickets (), aiming to establish a more sustainable and efficient production method. This study evaluates the extraction efficiency of two advanced ultrafine grinding techniques: (1) fluidized bed jet milling (FBJM) and (2) graded impact milling (GIM), alongside a traditional hand sieving method. A comprehensive analysis of the chemical composition of the extracted chitin was performed, measuring critical parameters such as moisture content, residual ash, and protein levels, while also assessing its physicochemical properties. The results demonstrate that the implementation of ultrafine grinding methods significantly enhances both the yield and purity of chitin, while also reducing raw material consumption. This highlights the potential of house crickets as a sustainable source of biomaterials. The findings provide essential theoretical insights and practical guidance for the future development and application of chitin derived from insects.

Wheat germ is a by-product of wheat flour milling and processing, and is valued for being the nutrient-rich center of wheat grains. In this study, hot air-stabilized wheat germ with five different particle sizes (coarse, medium, fine, ultrafine, and very fine) was prepared and mixed with wheat flour (WF) in a ratio of 8:92. The study focused on the effect of particle size of stabilized wheat germ on the thermomechanical, dynamic rheological, and fermentation properties of wheat flour and the quality of steamed bread.

Atherosclerosis (AS) is a chronic inflammatory disease caused by buildup of plaques in arteries that are made up of lipids. The present study investigated the interventional effects of sea cucumber ultrafine powder (SCUP) prepared by ultrafine grinding on AS by determining the changes in lipid levels, plaque formation, and expression of key proteins in an AS mouse model induced by high-fat feeding. The results showed that ultrafine grinding could effectively increase its polysaccharide release rate (up by 21 %).

An extensive investigation in limestone and dolostone ground in a planetary ball mill was achieved bearing in mind the different paths often observed in particle size reduction and agglomeration between these rocks and their increasing use in ultrafine size ranges for eco-friendly engineering applications. Two samples ground (dry) in a planetary ball mill up to 32 h were examined using laser scattering, physisorption, electron microscopy, X-ray diffraction, infrared spectroscopy and thermal analysis. Static hardness and crystal grain sizes were measured in parent rock specimens.

Low-grade tea, often underutilized due to its coarse texture and limited bioavailability, represents a significant resource waste. This study systematically investigated the synergistic effects of steam explosion (SE) and superfine grinding on enhancing the structural deconstruction, powder property, instant solubility, and diffusivity of low-grade. SE treatment induced critical physicochemical modifications, including hemicellulose degradation, lignin recondensation, and cellulose crystalline reorganization, which significantly weakened the lignocellulosic matrix.
