Problems solved by technology

[0004] Fruits, because of their high moisture content, delicious taste, and rich nutritional value, but generally berry fruits have high respiratory intensity, poor protective tissue, difficult storage and preservation, and short storage and shelf life, which will affect fruit farmers and consumers. bring great loss
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 cleaning is difficult, it is difficult to thoroughly wash Remove chemical fungicides, which will cause human health hazards after consumption

Abstract

The invention relates to a method for extracting a biological fresh keeping agent from Artemisia argyi. The method comprises the following steps: cleaning Artemisia argyi to remove foreign materials; crushing Artemisia argyi; putting the crushed Artemisia argyi in a pot, adding water according to a solid / liquid ratio of 1:1-2, immersing for 2-4h, heating with intense fire until boiling, decocting with slow fire for 20-30min, filtering, collecting the obtained filtrate, and preserving the filtrate in a 2-4DEG C refrigerator; and adding water to residues according to a solid / liquid ratio of 1:0.5-1, immersing for 1-2h, decocting for 30-60min, filtering, mixing the above obtained filtrates, and preserving the obtained filtrate mixture in the 2-4DEG C refrigerator. The invention also provides an application method of the biological fresh keeping agent extracted from Artemisia argyi. The biological fresh keeping agent extracted from Artemisia argyi is safe, nontoxic and nuisanceless in fruit freshness keeping, can replace chemical bactericides and antiseptic to realize fruit freshness keeping, and avoids the problems of environmental pollution and food safety of the chemical bactericides.

Description

technical field [0001] The invention relates to the field of fresh-keeping of fruits and vegetables, in particular to a method for extracting a biological preservative from wormwood and its application in fruit preservation. Background technique [0002] Wormwood is bitter, pungent and warm in nature and taste, enters the spleen, liver and kidney. "Compendium of Materia Medica" records: Artemisia argyi leaves are used as medicine, warm in nature, bitter in taste, non-toxic, pure yang in nature, clears twelve meridians, restores yang, regulates qi and blood, expels dampness and cold, stops bleeding and relieves miscarriage, etc. It is also commonly used in acupuncture. Therefore, it is also called "medical herb". Most of the popular "herb baths" in Taiwan use wormwood. Regarding the performance of Artemisia argyi, "Materia Medica" contains: "Artemisia moxibustion can moxibustion all kinds of diseases." Meridians, go through the three yin, regulate qi and blood, dispel cold...
