1. Tea Tree Oil Woolworths’ Antibacterial Research Tea tree oil, as a potential natural food antibacterial preservative, has unique advantages compared with chemically synthesized preservatives:
①Natural and environmentally friendly;
②High antibacterial activity, still has a killing effect on drug-resistant bacteria, and few factors affecting sterilization;
③ Non-toxic, harmless, less aggressive, no residue, in line with the social development direction of “green life, energy saving and environmental protection”. There have been reports in China that tea tree oil has been used in the field of food preservation and preservation. Try it as a new type of preservative for bananas and strawberries. The research on the bactericidal mechanism of Tea Tree Oil Woolworths is still in its infancy, and there is no clear method and method. Liposome studies have shown that terpenes have the ability to disrupt and penetrate lipid structures. Aromatic hydrocarbons and terpenes accumulate in the lipid bilayer of the cell membrane, affecting the structure and function of the membrane, causing the membrane to lose its integrity, increasing the permeability of protons and ions, causing the dissipation of proton kinetic potential, and causing intracellular damage due to intracellular changes. , lipophilic compounds have an effect on the lipid part of membrane proteins embedded in the cell membrane, and the effect on membrane proteins may cause a large change in the lipid environment, changes in the outer membrane lipopolysaccharide, and changes in the composition of the cell wall. Tea Tree Oil Woolworths and its components act on the microbial cell membrane to form perforations, so that the cell contents, especially potassium ions, seep out in large quantities, disrupt the normal distribution of lipid molecules in the double-layer structure of the cell membrane, and induce the hydrolase that degrades the cell wall to stimulate cell autolysis. Acting on normal cell membrane depolarization leads to cell death, resulting in increased sensitivity of cells to sodium chloride, inhibition of respiration, and electron microscopy observed cell morphological changes, loss of absorbed substances, formation of interstitial bodies, loss of cytoplasm, etc., indicating that after treatment with tea tree oil , the cell membrane is destroyed. Based on these data, it can be assumed that tea tree oil kills microorganisms in a manner similar to membrane-active disinfectants. Tea Tree Oil Woolworths acts as a membrane active disinfectant to kill many different microorganisms. Because Tea Tree Oil Woolworths contains a variety of components, the content of each component is different, the solubility and molecular weight are different, so the physical and chemical properties are different, and the rate of penetration through the cell wall and cell membrane structure is also different. In addition, the antibacterial activity of Tea Tree Oil Woolworths may exist at sites of action other than membranes or unknown components in tea tree oil, as well as other mechanisms of bactericidal action.
2. Antiviral activity of Tea Tree Oil Woolworths The antiviral activity of tea tree oil was first discovered in the research test of resistance to tobacco mosaic virus. On this basis, the researchers used eucalyptus oil as a control to study the effect of tea tree oil on the formation of herpes simplex virus types 1 and 2. The final results showed that Tea Tree Oil Woolworths inhibited the formation of herpes simplex virus by 50%, and found that Changes in concentration also had a significant effect on the inhibitory effect of the virus. In addition to this, Tea Tree Oil Woolworths has had the most significant impact on the virus in its free period. Since then, it has been explored whether tea tree oil can effectively inhibit influenza virus-induced dog kidney cells (MDCK). /8/34 induces apoptosis. It can be seen that Tea Tree Oil Woolworths can act on both enveloped and non-enveloped viruses, but there are few virus types reported so far.
