Abstract

The present invention discloses a natural compound preservative for vegetables and a preparation method thereof, and relates to the technical field of preservatives. The biological preservative is prepared from the following raw materials in parts by weight: 6-12 parts of olive leaves, 4-10 parts of haw, 5-12 parts of haw leaves, 2-8 parts of dandelions, 2-10 parts of lotus leaves, 2-10 parts of pomegranate peels, 4-10 parts of folium perillae, 6-12 parts of celery leaves, 2-4 parts of an onion extract, 2-6 parts of a broccoli extract, 4-8 parts of licorice, 1-4 parts of allium chinenes, 2-6 parts of tea leaves, 12-18 parts of sodium alginate, 0.5-3 parts of citric acid, 0.5-2 parts of lauryl sodium sulfate, 0.5-2 parts of laurate monoglyceride and 60-100 parts of water. The various components having excellent bacterium-preventing and sterilization effects are combined together, an antioxidant, a film-forming agent, etc. are added to have synergistic functions, effect of the preservative is increased, a preservation time of the preservative is extended, the used natural plant ingredients are combined, and the preservative is non-toxic and harmless.

Description

Technical field [0001] The technical field of the antistaling agent of the present invention specifically relates to a natural composite antistaling agent for vegetables and a preparation method thereof. Background technique [0002] At present, China has become the largest "vegetable basket" in the world. In 2009, China’s vegetable sown area and output accounted for 43% and 49% of the world’s respectively, ranking first in the world. After vegetable picking, due to changes in environmental conditions and the lack of a complete cold chain system and quality assurance system, it is prone to deterioration, rot, and chlorosis. The loss rate of vegetables produced in my country from the field to the table every year is as high as 25 %~30%. [0003] Vegetables have the characteristics of large leaf area, high water content, and brittle tissue. After harvest, the water evaporates quickly, is susceptible to mechanical damage, has strong respiration, and produces a large amount of respira...
