In this study, the physical, chemical, structural, and antioxidant characteristics of selenium (Se)-enriched sweet potato leaves (SSPL) powder produced through shear breaking and superfine grinding were examined. The superfine grinding SSPL powder had a brighter color, smaller particle size, and spherical shape. The superfine grinding SSPL powder showed improved dispersibility and solubility but reduced liquidity. Superfine grinding destroyed the crystalline area and decreased the thermal stability, while Se application did not significantly change the ordered structure. Correlation analysis showed that superfine grinding could improve crude fiber, crude lipid, total flavonoids, total polyphenol, and significantly enhance the antioxidant activities compared to shear breaking. Se enrichment can enhance the content of the crude protein and the DPPH• scavenging activity and reducing power. The flavor characteristic was not altered with the different crushing methods and Se concentrations. SSPL powder could serve as a potential resource for a new solid beverage.

To prepare superfine longan powder (SLP) rich in polysaccharides without adding extra ingredients, the production condition was optimized via ethanol pretreatment and response surface methodology, and the characteristics of SLP were investigated in contrast with those of the coarse longan powder. The optimal condition was determined to be: the solid-liquid ratio of 1:2, soaking time of 48 h, and ethanol concentration of 75.80%.

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.

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.

In this study, the ball milling method was used to produce superfine green tea powder (SGTP). We used the contents of chlorophyll, caffeine, tea polyphenols, and total free amino acids as indicators and combined the analytic hierarchy process (AHP) and fuzzy comprehensive evaluation to establish an AHP-fuzzy comprehensive evaluation approach applicable to SGTP. The production process of SGTP was optimized using the response surface methodology (RSM).

Superfine recycled regenerated silk fibroin (RRSF) monofilament sutures are designed to minimize surgical incisions, prevent scar formation, and facilitate precise suturing in cosmetic and plastic surgeries. However, balancing fineness and strength remains a challenge because the RRSF extraction process disrupts the hierarchical structure of natural silk fibers, leading to suboptimal mechanical properties. This study employed mechanical peeling and grinding to exfoliate β-sheets-rich silk fibroin nanofibrils (SFNF), which served as homologous reinforcing materials uniformly dispersed in the RRSF spinning system.
