Summary: This study investigated the effects of fermentation by Limosilactobacillus fermentum NCU001464 (Lm. fermentum NCU001464) on the physicochemical properties and biological activity of dried RRT fruit. After 48 hours of fermentation, the pH and monosaccharide content of RRT decreased, while the total phenolic content, antioxidant capacity, and xanthine oxidase (XO) inhibition increased. The binding interactions between fermented RRT and XO were confirmed to be stronger, with hydrogen bonds and van der Waals forces as the main binding forces.

Summary: This study analyzed the flavor compounds in Rosa roxburghii Tratt (RRT) that were fermented by different probiotics using headspace-gas chromatography-ion mobility spectrometry (HS-GC-IMS). The results showed that probiotics could improve the flavor of RRT, with Lactobacillus acidophilus having the largest effect. Additionally, after fermentation, RRT had increased levels of SOD and enhanced scavenging capacity of DPPH, ABTS, and OH free radicals.

Summary: By extracting and studying the free and bound polyphenols from Rosa roxburghii Tratt distiller's grains, it was found that the free polyphenols have higher antioxidant activity and can improve the gut microbiota structure and increase short chain fatty acid concentrations. The main components responsible for modulating the gut microbiota are quercetin, catechin, kaempferol, cyanidin, and baicalin. This research suggests that Rosa roxburghii Tratt distiller's grains are a promising source of natural antioxidants and prebiotic foods.

Summary: This study investigated the effects of high pressure processing (HPP) on various properties of Rosa roxburghii Tratt juice (RrT). HPP(>100 MPa) increased the levels of beneficial compounds such as SOD, ascorbic acid, total phenolics, and flavonoids. HPP also enhanced the aroma intensity of certain compounds while reducing the flavor concentration of nitrogen oxides. Overall, this study highlights the potential of HPP to improve the quality of RrT juice.

Summary: Endemic arsenism caused by coal burning is a unique biogeochemical disease in China, characterized by element imbalances. This study found that arsenic exposure increases the content of certain elements while decreasing others, and high levels of arsenic, iron, and lead, as well as low levels of selenium, increase the risk of arsenism. Additionally, the study reveals that Rosa roxburghii Tratt juice can reverse the element imbalances caused by arsenic and improve arsenism.

Summary: Lactobacillus acidophilus GIM1.208 (LA) can significantly improve the volatile flavor and sensory scores of Rosa rox-burghii Tratt (RRT). This study used widely targeted metabolomics to comprehensively analyze the effects of LA on flavor and activity of RRT. The results showed that LA fermentation increased the total phenolics and flavonoids content of RRT, while slightly decreasing the total triterpenoids content. The total antioxidant activity and hypoglycemic activity of RRT also increased.

Summary: In this study, three ethanol-tolerant non-Saccharomyces yeasts (Candida tropicalis, Pichia guilliermondii, and Wickerhamomyces anomalus) were isolated from Rosa roxburghii Tratt and found to have similar winemaking condition tolerances as Saccharomyces cerevisiae X16. However, they exhibited differences in growth, sugar metabolism, and sulphureted hydrogen activities. The mixed inoculation of these ethanol-tolerant yeast strains with Saccharomyces cerevisiae could regulate the volatile aroma characteristics of the fermented R. roxburghii wine, enhancing its aroma flavor. Therefore, these selected ethanol-tolerant yeasts have potential applications in the production of unique R. roxburghii wine.
