Abstract
The invention belongs to the technical field of daily chemical products and particularly relates to a fruit and vegetable preservative. The fruit and vegetable preservative comprises the following components in percentage by weight: 1%-3% of garlic essential oil, 0.5%-3% of chitosan, 2%-20% of an organic solvent; 1%-10% of a Chinese bulbul extract and the balance of sterile water. Compared with the prior art, the fruit and vegetable preservative has the advantages that through the synergy of the garlic essential oil, the chitosan and the Chinese bulbul extract, a protective film layer with permeability and water resistance can be formed on the surfaces of fruits and vegetables, and the fruit and vegetable preservative simultaneously has a good bactericidal effect; furthermore, the garlic essential oil, the chitosan and the Chinese bulbul extract which are used in the fruit and vegetable preservative are natural products extracted from plants, so that the fruit and vegetable preservative is safe to use, has no toxicity or side effects, is biodegradable and is in line with hygienic requirements.
Description
technical field [0001] The invention belongs to the technical field of daily chemical products, and in particular relates to a fresh-keeping agent for fruits and vegetables. Background technique [0002] In daily life, fruits and vegetables are the necessities of people's life, but the storage of fruits and vegetables is a big problem, which puzzles and affects people's normal life. Fruits and vegetables are not easy to store because fresh fruits and vegetables are still undergoing complex physiological, biological and physical changes after they are harvested. metamorphism etc. In order to solve the fresh-keeping problem of fruits and vegetables, some fruit and vegetable preservatives have appeared on the market. [0003] The currently used fruit and vegetable preservatives are mainly divided into two categories, namely chemically synthesized fruit and vegetable preservatives and natural fruit and vegetable preservatives. For a long time, people have mainly used chemical...
