Description

technical field [0001] The invention belongs to the technical field of food preservation, and in particular relates to a natural preservative. Background technique [0002] In daily life, microbes such as bacteria, mold, and yeast are the root causes of food spoilage. Food and beverages are easily attacked by microbes during storage and lead to spoilage, so that a large amount of food loses its edible value and is wasted. In order to improve this situation, preservatives are often used in production to delay the spoilage of food and beverages. Preservatives are a class of food additives that can inhibit microbial activity and prolong food shelf life. Since most preservatives are chemical preservatives, which are artificially synthesized and have certain toxicity, excessive addition in food and long-term use will cause certain damage to human health. In recent years, with the continuous improvement of people's living standards and health awareness, the requirements for food...
