Summary: The study found that oil droplets were always located in the casein-dominant regions regardless of the polymer types used for preparing emulsions. As Alg concentration increased, the gelation time of composite emulsion gels shortened, and the incorporation of oil droplets also affected the phase separation rate and extent between Alg and caseins.

Summary: The study demonstrated that pulsed-vacuum stimulation has a significant impact on the external gelation process of calcium-alginate hydrogel balls, particularly in the initial stages. Different working pressures directly affect the diffusion coefficient of Ca2+, weight reduction rate, and volume shrinkage rate, with a clear linear relationship between these parameters.

Summary: This study investigates the gelation behavior and properties of alginate samples in lithium, sodium, and potassium forms induced by calcium. The study finds that the effect of alkali metal counterions varies significantly with the calcium concentration regime. Four different regions were identified based on the molar ratio of calcium to guluronate. The study proposes a mechanistic model to explain the counterion dependence and advance the understanding and utilization of alginate gelation.

Summary: Macroscopic spatial patterns formed in calcium alginate gels consist of multi-concentric rings and streaks. The distance between concentric rings is proportional to the distance from which the calcium nitrate solution was dropped, and this proportionality factor depends on the temperature and alginate concentration. The patterns in the concentric rings are similar to Liesegang patterns, while the streaks resemble crack patterns resulting from inhomogeneous shrinkage during drying.

Summary: In recent years, strategies that partially replace animal proteins with plant proteins have been introduced. This study used microbial transglutaminase (MTGase) to crosslink lentil protein isolate (LPI) and casein, resulting in enhanced gelation properties. Increasing the concentration of casein in the LPI-casein binary gels led to improved mechanical and rheological properties, water holding capacity, and microstructural properties. Partial replacement of casein with 25% LPI in the MTGase-induced system yielded gels with similar properties to casein-alone gels, demonstrating the potential of LPI as a substitute for casein in food products.

Summary: This review introduces the extraction, structures, gelation behaviors and mechanisms of NPGP, PMTP, and CFP, while also summarizing the structure-property relation of major pectin types. It is found that both the intrinsic pectin structures and extrinsic environmental factors significantly affect the gelation of pectins, with the interplay between these factors sometimes resulting in unexpected gelation behaviors for pectins.

Summary: Designing composite food gels with polysaccharide-protein mixtures as building materials has gained attention in the food industry. The study fabricated composite gels with varying alginate addition amounts and fixed casein concentration. As the alginate concentration increased, the gel hardness initially increased, then decreased, corresponding to structural transitions of the composite gels.

Summary: This study developed novel gel beads with bigel structures based on alginate hydrogel and glycerol monostearate oleogel. The beads were able to encapsulate lipophilic and hydrophilic bioactives simultaneously. The increase in oleogel content led to larger bead size, higher oil filling level, and lower mechanical strength. The swelling of beads was inhibited by the increase in oleogel content. The gel structures provided good protection for curcumin, and about 70% of the original curcumin was retained after a 40-day storage test. The study provided valuable information for the development of functional food materials.

Summary: By constructing a soy protein isolate-chitosan-sodium alginate ternary complex coacervate phase, the interaction between soy protein isolate, sodium alginate, and chitosan was enhanced in the pH range of 5.0-7.0. The ternary coacervates showed viscoelastic solid behavior with honeycomb porous network structures, and increased stability to pH and ionic strength, particularly when prepared at pH 6.5. The in situ cross-linking of sodium alginate improved the structural properties, potentially offering a new carrier for incorporating bioactive ingredients into food products.

Summary: Insomnia is a common sleep disorder and natural sleep aids are gaining popularity as alternatives to prescription drugs. Recent studies have shown that marine polyphenols, specifically phlorotannins found in brown algae, have sedative-hypnotic effects. These effects are mediated through the gamma-aminobutyric acid type A-benzodiazepine receptor. The supplement containing phlorotannins from Ecklonia cava has been approved for improving sleep quality.

Summary: In this study, it was found that the ethanol extract of green kiwifruit peel (GKPEE) can promote sleep by increasing non-rapid eye movement sleep duration and decreasing sleep latency in mice. The sleep-promoting effects of GKPEE were comparable to diazepam, a commonly used sedative-hypnotic agent. Furthermore, GKPEE showed persistent effects even after sub-chronic administration, without tolerance phenomena. This suggests that GKPEE may be a promising natural sleep aid for treating sleep disorders, and its application can contribute to the utilization of food industry by-products and help solve environmental problems.

Summary: In recent years, more individuals have been staying awake and compensating for lack of sleep. Caffeine, the most extensively consumed compound globally, is mainly consumed through coffee. The arousal-inducing effects of green tea, which also contains high caffeine content, have not yet been studied. This study aimed to identify the arousal-inducing effect of green tea during a chronic administration period (three weeks) using sleep architecture analysis. Treatment with green tea significantly increased sleep latency and wakefulness for up to 3 hours. The arousal-inducing effect of green tea occurred without tolerance or withdrawal symptoms, similar to caffeine. However, green tea did not produce a better arousal-inducing effect than caffeine at a lower dose. These results suggest that green tea can control the arousal-inducing effects of caffeine due to the hypnotic effects of its other constituents.
