Embodiment 1

[0022] Put 498kg of water into the 500L reactor, then slowly add 0.5kg of coptis, 0.5kg of Phellodendron cortex and 1kg of licorice, stir evenly, soak for 6 hours, then heat to 120°C for 30-50 minutes and decoct, press filter for solid-liquid Separate and remove the dregs, collect the liquid part, add an appropriate amount of ethanol, let it stand at 4°C for 24 hours, filter through filter paper to remove the precipitate, recover the ethanol under reduced pressure at 75°C, and concentrate by rotary distillation at 85°C to obtain the Chinese herbal medicine extract, which is the final product.

Embodiment 2

[0024] Put 486kg of water into the 500L reactor, then slowly add 1.9kg of Coptidis Rhizome, 3kg of Baibu, 1.2kg of Cortex Phellodendron, 1.1kg of Angelica dahurica, 5kg of Licorice and 1.8kg of Poria, stir evenly, soak for 6 hours, and then heat to 120°C for Decoct for 30-50 minutes, press filter for solid-liquid separation to remove dross, collect the liquid part, add appropriate amount of ethanol, let it stand at 4°C for 24 hours, filter with filter paper to remove the precipitate, recover ethanol under reduced pressure at 75°C, and rotate at 85°C Distill and concentrate to obtain Chinese herbal medicine extract, which is the final product.

Embodiment 3

[0026] Put 490kg of water into the 500L reactor, then slowly add 1.5kg of Coptis chinensis, 2.5kg of Baibu, 1kg of Phellodendron cork, 3kg of licorice and 2kg of Poria cocos, stir evenly, soak for 6 hours, and then heat to 120°C for 30-50 minutes to fry Boil, press filter for solid-liquid separation to remove dregs, collect the liquid part, add appropriate amount of ethanol, stand at 4°C for 24 hours, filter through filter paper to remove precipitate, recover ethanol under reduced pressure at 75°C, and concentrate by rotary distillation at 85°C to obtain Chinese herbal medicine extract thing, the final product.

Abstract

The invention relates to a preservative composition containing Chinese medicinal herbs and application thereof, belonging to the technical field of preservatives. The preservative composition is prepared by adopting the steps of: 1, weighting 0.1-0.78 percent of goldthread, 0-1 percent of the tuber of stemona, 0.1-0.84 percent of golden cypress, 0-0.58 percent of liquorice root, 0.1-1.5 percent of liquorice, 0-0.8 percent of poria cocos and 94.6-99.6 percent of water according to the weight proportion, uniformly stirring, soaking for 6-8h, heating to 110-130 DEG C, preserving the temperature for 30-50min, decocting, press-filtering, and collecting filtrate for later use; and 2, adding alcohol, which is 1.5-2.5 times the volume of the filtrate, in the filtrate, standing at a temperature of 4 DEG C for 24-26h, filtering out sediment, decompressing and recycling the alcohol at a temperature of 75 DEG C, carrying out rotary distillation and condensation at a temperature of 85 DEG C until the volume is 8-15 percent of the original volume. The prepared preservative is natural and non-toxic, has no residual, good rot proofing effect on the foods, refreshing efficacy, low production cost and wide application range, and is safe in use.

Description

technical field [0001] The invention belongs to the technical field of preservatives, in particular to a preservative composition containing Chinese herbal medicine and its application. Background technique [0002] Anti-mold and anti-corrosion is an old topic. Before humans have chemically synthesized preservatives, they have found a large number of ways to extend the shelf life of food, such as high-salt pickling, high-molasses processing, acid, wine, smoking, and in water, underground storage etc. With the development of the food industry, traditional anti-corrosion methods can no longer meet its needs, and people have put forward higher requirements for food anti-corrosion methods: simpler operation, longer shelf life, and lower anti-corrosion costs. Based on this, the practice of using chemical products for food preservation became popular. The early chemical preservatives mainly included highly toxic products such as formaldehyde and nitrates. Later, dozens of chemic...
