Introduction from EGCG Supplier
Epigallocatechin gallate (EGCG) is one of the important active ingredients of polyphenols in tea. As a natural extract, it has strong activity, low toxicity and good safety. EGCG Supplier studies have shown that EGCG has a strong ability to resist oxidation, scavenge free radicals, inhibit bacteria and inhibit bacterial virulence. EGCG has broad-spectrum antibacterial ability and has a good inhibitory effect on Staphylococcus aureus, Bacillus subtilis, Escherichia coli, and Shewanella spp. However, different production processes are different. In the case of milk, EGCG Supplier finds be treated by three main food processing methods: high pressure steam sterilization, membrane filtration and pasteurization. Different treatment methods are used to inhibit EGCG. The effect of activity.
Staphylococcus aureus is widely distributed in nature and is one of the most common foodborne pathogens. It is caused by enterotoxin-induced bacterial food poisoning and is closely related to the safety of food processing and medicine. In China, the food poisoning incident caused by Staphylococcus aureus has increased year by year, and it has a high detection rate in various foods such as dairy products, raw milk, raw meat and aquatic products, resulting in food safety. The problem has become a key research topic. At present, chemical preservatives such as sorbic acid and benzoic acid are mainly used to inhibit the growth of microorganisms in foods by prolonging the cell structure, prolonging the storage time and maintaining the quality. At the same time, the research and application of natural plant-type preservatives has become more and more extensive, and the food safety and broad-spectrum antibacterial ability have been fully confirmed.
According to the Tests, EGCG Supplier have shown that EGCG has strong antibacterial and bactericidal ability after autoclaving, pasteurization and membrane filtration. Different treatment methods have certain effects on the activity of EGCG, and the antibacterial ability from the largest to the smallest is pasteurization > high pressure steam sterilization > membrane filtration method. Among them, the antibacterial activity of EGCG under the pasteurization treatment method is the strongest, and its MBC is 0. 062 5 mg/mL, when the lowest EGCG concentration (0.043 mg/mL) was used, the bacteriostatic rate was still 21%. Appropriate short-term high temperature enhances the solubility of EGCG, which is poorly soluble in water, in the culture medium, and the antibacterial ability is improved. However, the high temperature for a long time causes partial degradation of EGCG, thereby reducing the bacteriostatic effect.
