Method for extracting biological fresh-keeping agent from Scutellaria baicalensis, and applications of biological fresh-keeping agent in waxberry fresh keeping

Abstract

The present invention relates to a method for extracting a biological fresh-keeping agent from Scutellaria baicalensis. The method comprises: 1, sorting Scutellaria baicalensis root slices, and removing mud and other debris; 2, adding the Scutellaria baicalensis root slices to water according to a liquid material ratio of 1:3, and soaking for 1 h; 3, heating to achieve a boiling state, and cooking for 30 min; and 4, filtering the extraction solution to obtain the filtrate, storing at a temperature of 2-4 DEG C, and adding a phytic acid solution with a volume concentration of 0.1% to the filtrate so as to prepare the fresh keeping agent for spare, wherein the cooking is performed while stirring during the cooking process,. The present invention further provides applications of the biological fresh-keeping agent extracted according to the method of the present invention in waxberry fresh keeping. According to the present invention, the Scutellaria baicalensis is adopted as the raw material to extract the biological fresh-keeping agent to carry out fresh keeping on the waxberry, such that advantages of safety, no toxicity and no pollution are provided, the biological fresh-keeping agent can be used for replacing the chemical bactericidal agent and the preservative so as to be used for fresh keeping on the waxberry, and the problems of environmental pollution, food safety and the like of the chemical bactericidal agent are avoided.

Description

technical field [0001] The invention relates to the field of preservation of fruits and vegetables, in particular to a biological preservation agent extracted from scutellaria baicalensis and its application in preservation of bayberry. Background technique [0002] Scutellaria baicalensis is also known as camellia root and Tujin tea root. It is a perennial herb; the rhizome is thick, fleshy, up to 2 cm in diameter, elongated and branched. Scutellaria baicalensis is a perennial herb of Lamiaceae, and its root is used as medicine. Traditional Chinese medicine believes that Scutellaria baicalensis is bitter and cold in nature, enters the lung, heart, gallbladder, and large intestine meridians, and has the functions of clearing away heat and dampness, purging fire, detoxifying, and preventing miscarriage. , Damp-heat diarrhea, etc. have good effects. [0003] Red bayberry is a precious fruit, rich in protein, iron, magnesium, copper, vitamin C, citric acid and other benefici...

AI Technical Summary

Problems solved by technology

[0005] Red bayberry is delicious and rich in nutritional value, but the breathing intensity of red bayberry is high, the protective tissue is poor, it is difficult to store and keep fresh, and the storage period and shelf life are both short, which will bring great losses to fruit farmers and consumers.

At present, the conventional fresh-keeping method of berry fruits mainly adopts chemical fungicides, and the large-scale use of chemical fungicides will lead to drug resistance of pathogenic microorganisms and cause environmental pollution; in addition, because bayberry is difficult to clean, it is difficult to thoroughly Wash away the chemical fungicides, which will cause human health hazards after consumption
