Summary: The research on exopolysaccharides of lactic acid bacteria (LAB EPS) has focused on their isolation, production, and applications, highlighting their improved texture and rheological properties in fermented foods. LAB EPS are recognized for their mouthwatering flavors, antioxidant activity, cholesterol-lowering, and antimicrobial properties, with potential for enhancement through genetic engineering. Glycosyltransferases (gtfs) play a key role in EPS biosynthesis by LAB, but knowledge of their manipulation is currently limited, emphasizing the importance of further research in this area.

Summary: Lactic acid bacteria (LAB) synthesize exopolysaccharides (EPS), which have diverse technological properties and health-promoting benefits. LAB, especially those producing EPS, are used as probiotics to improve human health and prevent/treat specific diseases. They also play a role in promoting growth and inhibiting pathogens in food-producing animal husbandry. This review discusses the characteristics, usage, biological role, and potential contributions of LAB-produced EPS in improving productivity, animal health, and public health.

Summary: The objective of this study was to investigate the relationship between the microbial communities of sourdoughs from Xinjiang and Gansu regions in China and the quality of steamed bread. The study found that sourdough-based steamed bread was superior to yeast-based steamed bread in terms of its hardness, adhesiveness, flexibility, and chewiness. Significant differences in volatile flavor substances were observed between the two sourdoughs. The microbial communities and dominant strains in the sourdoughs varied between the Gansu and Xinjiang regions, leading to differences in the quality of the sourdoughs.

Summary: This study examined the impact of in situ-formed exopolysaccharides (EPS) in red bean sourdough on dough fermentation properties, bread-making quality and aroma characteristics. The EPS and sourdough acidification improved the height of dough fermentation, gas retention coefficient and viscoelastic properties of the dough. The resulting breads showed improved quality, with reduced baking loss and hardness, increased specific volume, and lower moisture loss and staling rate. Although there was a reduction in the overall content of aroma compounds, new aroma compounds were enriched in red bean sourdough bread. The study enhanced understanding of EPS's role in improving bread quality and offered strategies for producing nutritious and clean-label products.

Summary: The exopolysaccharides (EPS) produced by LAB in fermented milk improve its stability and viscosity. The properties of EPS depend on the composition and microstructure, which are influenced by different strains of lactobacilli. Fructose and negative-charged uronic acid play a significant role in changing the properties of EPS.

Summary: Sourdough is the result of a fermentation process involving LAB and yeasts, which increase acidification, leavening and flavor in bread. The demand for healthier products has led to an increased use of sourdough in bread-making. Different process parameters can influence the microbiota of sourdough, resulting in changes in both the sourdough itself and the resulting bread. Fermentation of sourdough involving probiotics can provide extra health benefits.

Summary: Demand for vegan foods has led to the use of plant-based milks, such as walnut milk, in the production of dairy products like ice cream. This study found that using walnut milk significantly affected the physical and chemical properties of ice cream samples, increasing their fat content and improving their rheological properties. Although it decreased the brightness value, walnut milk introduced different volatile compounds to the ice cream samples. Sensory evaluation showed that ice cream samples made with walnut milk were well-liked by the panelists and received similar scores to the control samples. This study demonstrates the potential use of walnut milk in ice cream production.

Summary: Carob flour is widely used in bakery formulations due to its various bioactive compounds and high percentage of fiber, protein, vitamins, and minerals. This study investigated the potential usage of carob flour incorporated with Type I sourdough in bread making. The addition of carob flour increased water absorption capacity and dough development time, while decreasing energy and extensibility value. The yeast number of sourdough decreased with the increase of carob flour addition. Sourdough fermentation improved the sensory acceptance of carob flour incorporated breads.
