Fruit and vegetable fresh-keeping agent containing trans-2-hexenoic acid, and application of fruit and vegetable fresh-keeping agent

Abstract

The invention discloses application of a fresh-keeping agent containing trans-2-hexenoic acid to fresh-keeping of fruits and vegetables, which is specific to preservation and fresh-keeping in the postharvest storage and transport process of the fruits and vegetables, and relates to the technical field of fresh-keeping of fruits and vegetables. Specifically, by using trans-2-hexenoic acid as the fruit and vegetable fresh-keeping agent, the fresh-keeping time of the fruits and vegetables such as strawberries, grapes, tomatoes in the storage process is prolonged, the rotting rate and nutrient loss are reduced, and the quality and appearance of the fruits and vegetables are kept. The used trans-2-hexenoic acid is a substance existing naturally in plants and meanwhile is also a flavoring substance permitted in the national standard, by using the trans-2-hexenoic acid as the fresh-keeping agent, the natural, safe, environment-friendly and convenient requirements are met, and the fresh-keeping agent has good development and application potentiality.

Description

technical field [0001] The invention belongs to the technical field of food preservation, and in particular relates to a fruit and vegetable preservation agent containing trans-2-hexenoic acid and its application. Background technique [0002] Fruits and vegetables are essential foods for people to maintain their health and improve their nutrition. The quality and safety of fruits and vegetables is the basic link of food safety, which directly affects people's health and life safety. Fruits and vegetables are easy to rot and deteriorate due to pathogenic bacteria infection, respiration and aging during storage and transportation, which is an important factor causing the deterioration of fruits and vegetables. The commonly used post-harvest fresh-keeping technologies for fruits and vegetables include physical measures and fruit and vegetable preservative treatment. Among them, the purchase and maintenance costs of physical fresh-keeping equipment such as low-temperature sto...

AI Technical Summary

Problems solved by technology

Among them, the purchase and maintenance costs of physical fresh-keeping equipment such as low-temperature storage and controlled-atmosphere storage are high, and chemical preservatives are mostly synthetic chemicals, which have problems such as low safety and large side effects.
