Abstract

The present disclosure belongs to the technical field of preservatives for fruits and vegetables, and in particular relates to a preservative for fruits and vegetables, a preparation method and applications thereof. Vegetables and fruits have a short shelf life and are perishable. The application of fruit and vegetable preservatives is of great significance to maintain the quality of vegetables and fruits and reduce the number of rotten fruits and vegetables. At present, the commonly used preservatives for fruits and vegetables are mostly chemical components, and there are certain safety hazards in long-term use. Studies have shown that there are traditional Chinese medicine extracts that can be used as preservatives for fruits and vegetables, which are safer than chemical preservatives. The present disclosure provides a fruit and vegetable preservative with mugwort extract as the main component, combined with effective components such as pueraria root and white chili, which can significantly reduce the decay rate of vegetables and fruits, and has important significance in practical production. The application of preservatives provides valuable reference experience.
