Abstract

The invention provides a fresh keeping agent for fruits and vegetables. The fresh keeping agent consists of 80-90 parts by weight of a traditional Chinese medicine extract and 10-12 parts by weight of microcrystalline fibers, wherein the traditional Chinese medicine extract is an aqueous extract of a mixture of divaricate saposhnikovia roots, cortex magnoliae officinalis, herba asari and Chinese magnoliavine fruits, the weight ratio of the divaricate saposhnikovia roots to the cortex magnoliae officinalis, to the herba asari and to the Chinese magnoliavine fruits is (1-3) to (1-2) to (2-4) to (2.5-3.5), and the fruits and vegetables are honey peaches or parsley. The invention also further provides a fresh keeping method for the fruits and the vegetables by using the fresh keeping agent for the fruits and the vegetables. The fresh keeping agent disclosed by the invention has excellent fresh keeping effects on the honey peaches and the parsley, and particularly the fresh keeping period of the honey peaches can be as long as 45-47 days. All the raw materials of the fresh keeping agent disclosed by the invention are frequently-used traditional Chinese medicines, other chemical agents are not used, the preparation technology of the fresh keeping agent is simple, and the fresh keeping agent can be in mass production.

Description

Technical field [0001] The invention belongs to the technical field of fruit and vegetable preservation, and relates to a fruit and vegetable preservative and a fruit and vegetable preservation method, in particular to a preservative and a fruit and vegetable preservation method that have high-efficiency preservation effects on peaches and celery. Background technique [0002] At present, in the field of fruit and vegetable preservation, the commonly used preservation methods are refrigeration preservation, modified atmosphere preservation and chemical preservation. Among them, refrigerated preservation and modified atmosphere preservation have high requirements for equipment and difficult operation, making it difficult to promote and apply in economically underdeveloped areas. [0003] At present, the chemical preservation technology mainly focuses on the use of some bacteriostatic agents or growth regulators to inhibit bacteria on fruits and vegetables or control the metabolism o...
