Nano antibacterial emulsion containing tea tree essential oil and preparation method thereof

Abstract

The invention discloses a nano antibacterial emulsion containing tea tree essential oil and a preparation method thereof. The nano antibacterial emulsion containing tea tree essential oil is preparedby an ultrasonic emulsification method, an emulsion system is prepared from 1-10% of tea tree essential oil, 1-6% of an emulsifier and water, and the emulsifier is Tween 80. In an antibacterial test,the nano antibacterial emulsion containing tea tree essential oil disclosed by the invention has a better antibacterial effect than unembedded tea tree essential oil, is longer in antibacterial time and has a slow-release effect. The nano antibacterial emulsion containing tea tree essential oil is novel in idea, simple in preparation method and high in practicability, the antibacterial activity ofthe tea tree essential oil is remarkably improved through the nano antibacterial emulsion containing tea tree essential oil, a safe and long-acting antibacterial agent is provided for the fields of food and medicine, and the application prospect is promising.

Description

technical field [0001] The invention belongs to the field of emulsion embedding and antibacterial technology, and in particular relates to a nano antibacterial emulsion containing tea tree essential oil and a preparation method thereof. Background technique [0002] Antibiotics have been the cornerstone of modern medicine since their discovery. Antibiotic resistance occurs when microorganisms such as bacteria become resistant to the drugs used to treat them. The continued overuse and misuse of antibiotics in human and animal health contributes to the emergence and spread of antibiotic resistance. Antibiotic resistance is occurring around the world, and new mechanisms of resistance are emerging and spreading globally, making it harder for a growing number of bacterial infections such as pneumonia, tuberculosis, sepsis, gonorrhea and foodborne illness Treatment, and sometimes no cure. Without urgent action, we will enter a post-antibiotic era where common infections and min...

Problems solved by technology

[0004] However, due to the volatilization, photolysis and oxidation of plant essential oils, the retention time in the environment is too short and the degradation is too fast to exert its biological activity, which will further reduce the control effect and duration of the preparation to a large extent; Due to its poor stability and solubility and long-term storage, it is easy to deteriorate and is rarely extracted directly.
