Soy protein has shown remarkable effectiveness in reducing fat mass compared with other protein sources, and exercise has the potential to further enhance this fat loss effect. Previous studies have demonstrated that soy protein intake leads to decreased fatty acid synthesis, which contributes to its fat-loss properties. However, the exact mechanism by which these lipids are consumed remains unclear. To investigate this, we conducted a comprehensive study using C57/BL6 male mice, comparing the effects of soy and casein proteins with and without exercise (Casein-Sed, Casein-Ex, Soy-Sed, and Soy-Ex groups) under high- and low-protein conditions (14% or 40% protein). Our findings revealed that combining soy protein intake with exercise significantly reduced epididymal white adipose tissue (eWAT) weight, particularly in the high-protein diet group. Further analysis revealed that exercise increased the expression of lipid oxidation-regulatory proteins, including mitochondrial oxidative phosphorylation protein (OXPHOS) complexes, in the plantaris muscle regardless of the protein source. Although soy protein intake did not directly affect muscle mitochondrial protein expression, the activity of OXPHOS complex I was additively enhanced by exercise and soy protein under the 40% protein condition. Notably, complex I activity inversely correlated with eWAT weight in the soy protein diet group. These results highlight the potential link between improved complex I activity induced by soy protein and fat mass reduction, which emphasizes the promising benefits of combining soy protein with exercise in promoting fat loss. The findings revealed that soy protein intake combined with exercise resulted in reduced adipose tissue weight compared with that obtained with casein protein intake. Furthermore, the joint impact of exercise and soy protein consumption resulted in enhanced activity of oxidative phosphorylation protein (OXPHOS) complex I in fast-twitch muscles, which appears to be associated with fat mass reduction. These findings elucidate the potential additive effects of soy protein and exercise on body weight management.

Although Tara tannins (TT) have given soy protein isolate (SPI) film antioxidant properties, the mechanical and barrier properties were not significantly improved. In this work, dialdehyde cellulose nanofibers (DACNF) were obtained through oxidation using sodium periodate and incorporated into SPI film with TT to obtain antioxidant and bacteriostatic properties. With increased DACNF content, the anti-swelling, mechanical and barrier properties of SPI film were enhanced due to a double-crosslinked structure based on the covalent and hydrogen bonds formed between DACNF, TT and SPI.

The rising demand for plant-based meat analogues presents challenges in replicating the sensory qualities of animal meat. This study investigates the impact of Pichia-derived porcine myoglobin (PMb) and bovine hemoglobin (BHb) on the flavor profile, sensory attributes, macrostructure, color, and texture of high-moisture extruded soy protein concentrate-wheat gluten. The addition of PMb and BHb significantly altered the flavor profile by decreasing aldehyde content (hexanal and nonanal), while the contents of ketones (2,3-octanedione and 3,5-octadien-2-one), pyrazines (2-ethyl-6-methylpyrazine), and furans (2-pentylfuran) were increased.

Legume leaves exhibit diverse compound forms, with various regulatory mechanisms underlying the development. The transcription factor-encoding KNOXI genes are required to promote leaflet initiation in most compound-leafed angiosperms. In non-IRLC (inverted repeat-lacking clade) legumes, KNOXI are expressed in compound leaf primordia but not in others (IRLC).

Common adhesives for nonstructural applications are manufactured using petrochemicals and synthetic solvents. These adhesives are associated with environmental and health concerns because of their release of volatile organic compounds (VOCs). Biopolymer adhesives are an attractive alternative because of lower VOC emissions, but their strength is often insufficient.
