Problems solved by technology

[0006] Cherry tomatoes belong to berry fruits with delicious taste and rich nutritional value. However, cherry tomatoes have high respiratory intensity, poor protective tissue, difficult storage and preservation, and short storage and shelf life, which will bring great harm to fruit farmers and consumers. to great loss
And the fresh-keeping method of conventional berry class fruit is mainly to adopt chemical bactericide at present, and a large amount of use of chemical bactericide can cause pathogenic microorganism to produce drug resistance, and cause environmental pollution; Difficult to wash off chemical fungicides thoroughly, which will cause hidden dangers to human health after consumption

Abstract

The invention relates to a method of extracting a biological fresh-keeping agent from scutellaria baicalensis, and further provides an application of the biological fresh-keeping agent in fresh keeping of cherry tomatoes. The method comprises the following steps that 1. scutellaria baicalensis roots are cleaned, and impurities such as soil are removed; 2. scutellaria baicalensis roots are smashed to 10-50 mesh; 3. water is added to scutellaria baicalensis root powder according to a liquid-to-solid ratio of 1 to (3-5), the mixture heated to be boiled for 10-20min; and 4. an extracting solution is filtered, and a filtrate is obtained and stored at 2-4 degrees. The invention also discloses application of the extracted biological fresh-keeping agent in preservation of cherry tomatoes. The method has the beneficial effects that the biological fresh-keeping agent is extracted by taking scutellaria baicalensis as a raw material and used for the fresh keeping of the cherry tomatoes, is safe, nontoxic and pollution-free, and can replace a chemical sterilizer and a preservative for the fresh keeping of the cherry tomatoes, so that the pollution of the chemical sterilizer to an environment is avoided and the food safety is ensured.

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 cherry tomatoes. 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] Cherry tomatoes are also called pearl tomatoes and cherry tomatoes, which can be both vegetables and fruits. ...
