Abstract
ABSTRACTThis study evaluated the inhibitory effects of samples extracted by different solvents from bayberry on eight common foodborne pathogens and investigated the main bacteriostatic components of bayberry extracts using ultraviolet and ultraperformance liquid chromatographic-electrospray mass spectrometry. Among the different solvent extracts, the water-extracted sample (BE1) had the greatest average inhibition zone diameter for the tested foodborne pathogens, which reached 22.1 mm. Among them, Salmonella paratyphi, Listeria innocua, and Listeria monocytogenes were most sensitive to BE1, and the lowest minimal inhibitory concentration value was 2.07 mg/mL. The polyphenol content in BE1 was the highest at 24.11 mg/mL. In addition, the main bacteriostatic component in BE1 was identified as cyanidin 3-O-glucoside. As natural antimicrobial agents, the antimicrobial compounds in berries are likely to have many important applications in food and medical industries in the future.
Highlights
Chinese bayberry fruit (Myrica rubra Sieb. et Zucc.) is native to eastern Asia, mainly China, and it is very popular with the local consumers because of its sweet/sour taste, flavor, and color.[1,2] All parts of the bayberry plant are used in Chinese traditional medicines.[3]
The results showed that the bayberry extract had a significant inhibitory effect on Serratia marcescens and Pseudomonas aeruginosa, and the addition of plum extract could prolong the shelf life of the surimi products storage at room temperature.[31]
The antibacterial effects of samples extracted with different solvents from bayberry were studied and the water-based extraction had the greatest antibacterial effect and the highest total phenolic content
Summary
Chinese bayberry fruit (Myrica rubra Sieb. et Zucc.) is native to eastern Asia, mainly China, and it is very popular with the local consumers because of its sweet/sour taste, flavor, and color.[1,2] All parts of the bayberry plant are used in Chinese traditional medicines.[3]. Et Zucc.) is native to eastern Asia, mainly China, and it is very popular with the local consumers because of its sweet/sour taste, flavor, and color.[1,2] All parts of the bayberry plant are used in Chinese traditional medicines.[3] Bayberries are an important source of phytochemicals, such as phenolic acids, anthocyanins, and flavonol glycosides. Bayberry extract can prevent the metabolic disorders of C57BL/6 mice induced by a high-fat diet.[16] The flavonoid extract from Chinese bayberry has a protective role against ethanol-induced oxidative damage in mice livers.[17] In addition, the relevant researchers have proved that Myricitrin protects against peroxynitrite-mediated DNA damage and cytotoxicity in astrocytes.[18] there are many active components in bayberry extract, and the synergistic effects of functional components are complex. There are few studies on the effective functional components in bayberry extract
