We experimentally and theoretically investigate the size effect of gelation using Resorcinol-Formaldehyde aerogels. We find a clear dependence of gelation time on the sample size under mild shear conditions. We developed a theoretical model based on Smoluchowski's aggregation model adding, however, a growth term which accounts for the continuous growth of the colloidal particles while clustering happens. The model is solved analytically and agrees with our experimental observations for base catalyzed RF-gels.

Chicken thigh is a popular and widely consumed meat product. However, its high moisture content and susceptibility to microbial spoilage limit its shelf life. To address this issue, we investigated the efficacy of an edible coating based on alginate nanoparticles (AlgNPs) containing menthol, essential oil (EO), or their combination for extending the shelf life of chicken thigh.

Anthropogenic and industrial activities have released large amounts of mercury (Hg) into the hydrosphere. Hg ultimately deposits in sediments and could be re-released into the water environment, threatening the ecological system. Active capping is considered a suitable remediation method due to its relatively low cost and in-situ decontamination feasibility.

This study investigates the effects of ultrasound synergistic pH shift modification on the structural and functional properties of Hericium erinaceus (HE) proteins. The modification resulted in significant changes in the molecular structure of HE proteins, including increased solubility (49.69 % at pH 1.

To ameliorate the limitations of corn starch (CS) processing, Radix Paeoniae Alba polysaccharide (RPAP) was used to modulate the physicochemical and digestive properties of CS. The main purpose of this paper is to investigate the effects of RPAP on the pasting, rheological, thermal, structural, and digestive properties of CS. The results show that the addition of RPAP could increase the peak viscosity and final viscosity of CS gel, and RPAP could increase the apparent viscosity, storage modulus, loss modulus, hardness, and strength of CS gel, implying that RPAP can effectively improve the pasting and viscoelasticity properties of CS.
