Article Abstract
The consumption of teas has been increasing with the dissemination of information regarding the health benefits of its constituents. Obtaining food products with healthier profiles is already a reality for industry with the increasing development of new functional ingredients, including the use of tea and its derivatives (extracts). This work aimed to evaluate the encapsulation of green tea extract powder in lipid microparticles (LMP) by the spray chilling method and in ionic gelation microparticles (IGMP) by the ionic gelation method to obtain polyphenol-rich water insoluble components. Microparticles were adequately obtained in both methods, with typical physical characteristics consistent with the results in literature results, 83.5 ± 2.8% encapsulation efficiency for LMP and 72.6 ± 0.4% for IGMP, and antioxidant activity (IC50 μg/mL) of 33,169.4 ± 123.8 (IGMP) and 2099.7 ± 35.3 (LMP). The microparticles samples were considered suitable as ingredients for add polyphenols in foods.

Background And Aim: Probiotic viability remains a critical challenge during gastrointestinal (GI) transit, storage, and feed processing. Conventional encapsulation materials often fail under acidic and thermal stress. This study aimed to develop and characterize a novel, eco-friendly microencapsulation system using (FP) seed extract as a natural encapsulating matrix for (LP) WU2502, enhancing its functional resilience and storage stability.

In this study, tannic acid (TA) was applied to remodel the structure of quercetin-loaded oat globulin fibrils (UF-Que), to form novel fibril-based composite hydrogels (UF-Que-TA) to encapsulate Que. The hydrogels were prepared by varying the [TA]/[UF] ratio to investigate the impact of TA on gelation behavior, microstructure, molecular interactions, and stability of Que. Physicochemical results indicated that the incorporation of TA significantly enhanced the gel strength and promoted non-covalent interactions including hydrogen bonding, hydrophobic interactions, and ionic interactions.

Kappa carrageenan (KC), a sulfated polysaccharide derived from red seaweed, exhibits distinct gelation properties that are influenced by ionic strength and thermal conditions. While its behavior in aqueous media is well-established, understanding KC's gelation mechanisms in non-aqueous solvents (like glycerol) remains limited. This study investigates the conformational and rheological properties of kappa carrageenan in glycerol, focusing on the effects of sodium salts (NaCl, NaHPO, NaPO) at varying concentrations and preparation temperatures (60 °C and 80 °C).

We present a microfluidic strategy for fabricating high-concentration alginate microgels through a combination of shell-mediated gelation and osmotic shrinkage. Using a water-in-oil-in-water double emulsion platform, we introduce a thermally responsive oil shell that undergoes a phase transition upon cooling. This phase change allows spatial control over calcium ion diffusion into the alginate core by forming transient diffusion channels, resulting in localized and uniform ionic crosslinking.
