Abstract

The invention discloses a fruit fresh-keeping agent prepared from a glycyrrhiza glabra extractive. The fresh-keeping agent comprises the following materials in parts by weight: 0.5-2 parts of glycyrrhiza glabra extractive, 8-15 parts of fennel extract, 3-8 parts of starch, 1-3 parts of salt, 0.5-1 part of vitamin C, 10-15 parts of ethanol, 2-4 parts of baking soda, 0.5-1 part of capsaicin, 1-3 parts of konjac gum, 1-3 parts of candelilla wax, and ozone of 0.1-0.15 ppm. All added materials are edible. Glycyrrhiza glabra is subjected to ethanol assisted supersonic wave extraction so as to obtain the glycyrrhiza glabra extractive. The glycyrrhiza glabra extractive contains rich glycyrrhiza glabra flavone, glabrene and gabridin, which are combined with the fennel extract, the starch, the konjac gum and the candelilla wax so as to form a compact layer of protective film with a significant antioxidation effect, increase the antioxidation capability of fruit peel, decrease free radicals, slow fruit metabolism, and prolong fruit fresh-keeping time.

Description

technical field [0001] The invention relates to the technical field of preservatives, in particular to a melon and fruit preservative prepared from Glycyrrhiza glabra extract. Background technique [0002] With the development of science and technology and the improvement of people's living standards, people's demand for melons and fruits produced in different regions and different seasons has gradually increased. Greenhouse melons and fruits are far from meeting the existing needs. They can be transported in other places or stored for a long time to meet people's needs. However, melons and fruits often contain more water, and if stored for a long time, the melons and fruits will be dehydrated and taste bad. , it will also cause the melons and fruits to rot due to moisture, or the dehydration or rot of the melons and fruits due to temperature changes during transportation, thus not only polluting the environment, but also bringing economic losses; the current preservation te...
