Summary: Sourdough fermentation is an ancient technique that improves bread quality and has nutritional and health benefits. The fermentation process produces metabolites and chemical reactions that give the product unique characteristics and high sensory quality. Mastery of fermentation allows for adjustments in gluten levels, starch digestibility, and the bio-accessibility of vitamins and minerals. This review focuses on the steps of sourdough fermentation, the microorganisms involved, and advances in bread production with functional properties, including the impact of probiotics on human health, metabolite production, and microbial enzymes used in the bakery industry.

Summary: This study investigated the effects of bacterial species and fermentation time on wheat bread quality, FODMAP content, and antioxidant activity. The results showed that adding lactic acid bacteria and extending fermentation time can effectively reduce FODMAPs and increase antioxidants. However, prolonged fermentation time may affect the sensory properties of the bread.

Summary: This study evaluated the impact of sourdough fermentation on eGI, in vitro starch digestibility, and texture of experimental breads. Fermentation type and temperature significantly affected RS, RDS, HI, and eGI values, with type-2 fermentation showing higher RS content and lower eGI values. These findings suggest that fermentation type and temperature can influence the nutritional and sensory properties of sourdough bread, with type-2 fermentation producing bread with higher RS and lower eGI.

Summary: Petroleum hydrocarbons and toxic metals are harmful to ecosystems, and fungi have the potential to be used in biological remediation due to their metabolic and morphological plasticity. Fungal bioinoculants can produce various bioproducts that can assist in mycoremediation, but their real application requires collaboration with bacteria, microalgae, plants, or animals. The rapid development of emerging technologies has boosted fungal bioprocesses and their potential application in the remediation of these contaminants.

Summary: This study compares the effects of microbial glycolipids and synthetic surfactant SLES on human keratinocyte cells. The results show that microbial glycolipids have different effects on the cells depending on their chemical structure. Acidic sophorolipids and mono-rhamnolipids have minimal effects on cell viability and morphology, while di-rhamnolipids can reduce inflammation and increase the production of immune factors.

Summary: The terms biosurfactants (BSs) and bioemulsifiers (BEs) refer to microbial-origin surface-active molecules that are widely used in various industries, including the food industry. BSs are low-molecular-weight compounds that significantly reduce surface tension, while BEs are high-molecular-weight molecules with efficient emulsifying properties. The toxic nature of chemical-based surfactants and the growing demand for green label additives have increased the interest in BSs/BEs in food formulations. However, the commercial production of BSs/BEs faces challenges such as optimizing fermentation parameters, high downstream costs, and limited adoption due to safety concerns. Further research and regulatory approvals are needed to assess the safety and potential risks associated with the use of BSs/BEs as food additives.

Summary: Aquatic habitats are highly vulnerable to chemical pollution, especially antimicrobials, leading to an increase in antimicrobial resistance (AMR) gene prevalence. Synthetic and biological surfactants, such as sodium dodecyl sulfate (SDS) and rhamnolipids, are being developed as alternatives to counteract pathogenic bacteria. In this study, the effects of rhamnolipid and SDS on aquatic biofilms were tested in a freshwater stream. The results showed that rhamnolipid exposure led to a greater number of unique taxa in the biofilms compared to SDS treatments and controls. Although not significant, surfactant-treated biofilms had a higher prevalence of AMR genes, with rhamnolipid-exposed biofilms showing the highest presence of AMR genes and classes.

Summary: This study proposes the use of freeze-dried sourdough adjuncts based on Lactiplantibacillus plantarum for making new types of sourdough breads. Three different adjuncts were used: Lactiplantibacillus plantarum alone, unfermented pomegranate juice, and pomegranate juice fermented by the same strain. The breads made with these adjuncts showed improved physicochemical, microbiological, and nutritional characteristics compared to commercial sourdough bread. The best results were obtained with the fermented pomegranate juice adjunct.

Summary: In this study, a wild-type Lacticaseibacillus paracasei SP5 (L. paracasei SP5) potential probiotic strain was used to ferment an apple-orange-carrot mixed juice for 1 day. After fermentation, the juice was refrigerated at 4 degrees C and analyzed for microbiological stability, volatile characterization, physicochemical properties, sensorial validation, and viability of the probiotic strain. The stored juice showed no yeast/fungi growth and retained a viability of 8.28 Log CFU/mL of L. paracasei SP5 even after 4 weeks of cold storage. The fermented juice exhibited changes in pH, TTA, organic acids content, residual sugar content, and volatile profile. The sensorial properties of the fermented juice were positively influenced.

Summary: This research proposes a method to produce sweet wine from the by-product of high-quality Corinthian currants, involving complete fermentation and the use of alcohol-tolerant yeast. Sugar extraction from the by-product or the addition of syrup made from the by-product can adjust sweetness, and fermentation can be stopped by adding ethanol at the desired sugar level. The non-fortified wines have better characteristics (mainly in terms of acidity, antioxidant capacity, and phenolic content) than fortified wine, and adjusting sweetness using the by-product is the simplest and least costly method. This method can produce high-quality sweet wines with a characteristic fruity flavor, which can be commercialized as specialty currant beverages or liqueurs.

Summary: This study investigates the variations in lipid digestion profiles among individuals of different ages using in vitro digestion models. The findings suggest that adults have a more comprehensive lipid digestion compared to infants, and infants tend to release shorter chain length and more saturated free fatty acids during digestion. Additionally, the particle sizes in the stomach of the elderly were consistently larger. This study enhances our understanding of how lipids with different degrees of unsaturation undergo digestion in diverse age groups.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
