Abstract

The invention provides application of shiitake mushroom volatile oil in preparation of antibacterial drugs or food preservatives. Experimental results show that the shiitake mushroom volatile oil hasa wider antibacterial spectrum, has a better inhibitory effect on drug-resistant bacteria and especially methicillin-resistant staphylococcus aureus, is low in toxicity and convenient to extract, andhas great application prospects when being developed into drugs; and the shiitake mushroom volatile oil has certain antibacterial activity on the bacteria such as proteus species and typhoid bacilluscausing food deterioration, so that the shiitake mushroom volatile oil has certain application potential in the aspects of preventing food deterioration, preventing food poisoning and the like and hasdevelopment potential of serving as a natural preservative.

Description

technical field [0001] The invention relates to the application of the volatile oil of shiitake mushrooms in the preparation of antibacterial drugs or food preservatives. Background technique [0002] Mushrooms (Lentinus edodes), also known as mushrooms, shiitake mushrooms, flower mushrooms, and mushrooms, are known as the "Queen of Plants" and "The Meat of Vegetables". In addition, Lentinus edodes also has good medicinal value. Modern research It is believed that shiitake mushrooms have anti-tumor, anti-oxidation, and immunity-enhancing effects. The production, export and consumption of shiitake mushrooms in my country rank first in the world. However, shiitake mushrooms in my country are mainly dry and fresh products, with a single product form and additional The value is low, and the level of deep processing is relatively backward. [0003] With the continuous improvement of the comprehensive scale of my country's shiitake mushroom industry, its comprehensive utilization a...
