The present work investigated effects of high-pressure homogenization (HPH) pressure (0, 40, 80 and 120 MPa) on physicochemical, functional and rheological properties of clam myofibrillar protein (CMP). Results showed that HPH changed the CMP secondary and tertiary structures. Absolute zeta potential and protein solubility increased but particle size and turbidity of CMP decreased after HPH treatment. Both of emulsifying properties and foaming properties were significantly improved. The shear stress, apparent viscosity and the viscosity coefficients reduced, but flow index increased. Application of HPH improved the physicochemical, functional and rheological properties of CMP, and 120 MPa was the optimal pressure for modification.

Agroforestry systems are known to enhance soil health and climate resilience, but their impact on greenhouse gas (GHG) emissions in rubber-based agroforestry systems across diverse configurations is not fully understood. Here, six representative rubber-based agroforestry systems (encompassing rubber trees intercropped with arboreal, shrub, and herbaceous species) were selected based on a preliminary investigation, including Hevea brasiliensis intercropping with Alpinia oxyphylla (AOM), Alpinia katsumadai (AKH), Coffea arabica (CAA), Theobroma cacao (TCA), Cinnamomum cassia (CCA), and Pandanus amaryllifolius (PAR), and a rubber monoculture as control (RM). Soil physicochemical properties, enzyme activities, and GHG emission characteristics were determined at 0-20 cm soil depth.

Vegetation ecological restoration technology is widely regarded as an environmentally sustainable and green technology for the remediation of mineral waste. The appropriate ratio of amendments can improve the substrate environment for plant growth and increase the efficiency of ecological restoration. Herbs and shrubs are preferred for vegetation restoration in abandoned mines because of their rapid establishment and easy management.

In this study, water-soluble fraction (WSF), chelator-soluble fraction (CSF), and sodium carbonate-soluble fraction (NSF) were sequentially fractionated from pear pulp, of which physicochemical properties and hypolipidemic activities in vitro were evaluated. They showed distinct monosaccharide composition, surface morphology, nuclear magnetic resonance (NMR), and Fourier transform infrared (FT-IR) spectrums. WSF and NSF were identified as high methyl-esterified pectic polysaccharides with degrees of methyl esterification (DM) of 85.

This study explores the innovative combined effects of alkaline isolation with ultrasound pretreatment on the physicochemical properties of acorn (Quercus brantii) starch. The optimal pH for maximizing the yield of alkaline-isolated acorn starch (AAS) was determined, followed by comparison with alkaline-isolated defatted acorn starch (ADAS), ultrasound-pretreated acorn starch (UAS), and ultrasound-pretreated defatted acorn starch (UDAS). The results demonstrated substantial improvements in yield and purity, with the highest yield (68.
