Problems solved by technology

[0003] 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

Embodiment 1

[0013] A method for extracting biological antistaling agent from Cortex Phellodendri, the operation steps are as follows: 1. Clean the Cortex Cortex to remove impurities such as soil and leaves; 2. Pulverize the Cork Cork; , add ethanol solution at a ratio of 1:10 to the material-liquid ratio, install a reflux condenser, heat and reflux in a hot water bath for 0.5h, and cool and stand for 0.5h, filter with suction, and take the filtrate; 4. Filter the residue with The ratio of solid to liquid is 1:10, add ethanol solution, reflux again for 1h, cool and stand for 0.5h, filter with suction, and get the filtrate; 5, combine the filtrate twice, and steam the ethanol solution under the reduced pressure of the water pump; 6, with Add 3% acetic acid solution to the extract at a volume ratio of 1:1, heat to dissolve, and filter while hot to remove insoluble matter to obtain a biological preservative. Among them, Phellodendron cork was crushed to 100 mesh.

Embodiment 3

[0019] A method for extracting biological antistaling agent from Phellodendron, the operation steps are as follows: 1. Clean the Phellodendron to remove soil, leaves and other sundries; 2. Pulverize the Phellodendron; 3. Put the pulverized Phellodendron into a round bottom flask In the process, add ethanol solution at a ratio of 1:11 to the ratio of material to liquid, install a reflux condenser, heat and reflux in a hot water bath for 1h, and cool and stand for 0.5h, filter with suction, and take the filtrate; 4. Add ethanol solution at a liquid ratio of 1:11, reflux again for 1.2h, cool and stand for 0.5h, filter with suction, and take the filtrate; 5. Merge the two filtrates, and distill the ethanol solution under the reduced pressure of the water pump; 6. Add 3.5% acetic acid solution to the extract at a volume ratio of 1:1.5, heat to dissolve, and filter while hot to remove insoluble matter to obtain a biological preservative. Among them, Phellodendron pulverized to 150 m...

Abstract

The invention relates to a method for extracting a biological preservative from phellodendron barks. The method comprises the following operating steps: (1) screening the phellodendron barks, and removing foreign matters, such as soil and tree leaves; (2) crushing the phellodendron barks; (3) putting the crushed phellodendron barks into a round-bottomed flask, adding an ethanol solution into the round-bottomed flask in accordance with that the material / liquid ratio is 1: (10-12), mounting a refluxing condenser pipe, carrying out heating reflux for 0.5-1.5 hours in hot-water bath, cooling and standing for 0.5 hour, and carrying out suction filtration so as to obtain a filtrate; (4) adding an ethanol solution into filtrated residue in accordance with that the material / liquid ratio is 1: (10-12), carrying out condensation reflux for 1-1.5 hours, cooling and standing for 0.5 hour, and carrying out suction filtration so as to obtain a filtrate; (5) combining the filtrates obtained twice, and distilling the ethanol solution under water pump decompression; (6) adding a 3-4% acetic solution into an extract in accordance with that the volume ratio is 1: (1-2), heating to dissolve, and carrying out suction filtration while the solution is hot so as to remove insoluble substances, thereby obtaining the biological preservative. The biological preservative, extracted from the phellodendron barks which serve as a raw material, disclosed by the invention is used for preserving fruits, is safe, non-toxic and nuisance-free and can be used for keeping Chinese dates fresh instead of chemical bactericides and preservatives, and the problems of environmental pollution, food safety and the like caused by the chemical bactericides are avoided.

Description

technical field [0001] The invention relates to the field of biological preservation, in particular to a method for extracting a biological preservation agent from Cortex Phellodendri and its application. Background technique [0002] Cortex Phellodendron is the dry bark of the Rutaceae Phellodendron or Cortex Phellodendron. The former is commonly called "Sichuan Phellodendron", and the latter is commonly called "Guan Phellodendron". It can be used as medicine, with bitter and cold nature and flavor, and has the effects of clearing away heat and dampness, purging fire and removing steam, detoxifying and treating sores. Phellodendron amurense is distributed in Northeast China and North China provinces and other regions. It likes to grow in mountainous areas and miscellaneous forests. It has strong adaptability and is suitable for cultivation in sunny places and can also resist severe cold. Phellodendron Phellodendri is a commonly used traditional Chinese medicine. It is col...
