Method for preserving and fresh keeping of cherry tomatoes

Abstract

The invention discloses a method for preserving and fresh keeping of cherry tomatoes, belonging to the technical field of preservation and fresh keeping of fruits and vegetables. The method comprises the steps of: 1. harvesting cherry tomatoes; 2. preparing a preservative, wherein the preservative comprises the components by weight part: 0.0015-0.003 percent of eugenol, 0.5-1.5 percent of chitosan, 1.5-3.0 percent of citric acid and the balance of water; 3. soaking the cherry tomatoes; and 4. storing the cherry tomatoes, and the like. All components of the preservative are purely natural, thereby having the advantages of no toxicity, safety, no pollution to the environment, and the like. After the cherry tomatoes are processed, the skins of the cherry tomatoes are good in color, the incidence of diseases is reduced by 60-85 percent, the weight loss ratio is reduced by 30-50 percent, and the loss of VC is remarkably reduced. The method can be popularized and applied to a cherry tomato planting region.

Problems solved by technology

Although in order to ensure tomato production and post-harvest preservation, the use of chemicals is unavoidable, but due to the carcinogenic effects, toxic residues, environmental pollution, and microbial resistance caused by chemicals, and because people pay more and more attention to food safety, chemical The application of drugs in food production has been more restricted. Therefore, it is urgent to find drugs that are less harmful to human health, safety and the environment to replace traditional chemicals.
