Technical Field

The invention relates to the technical field of food preservation, in particular to natural compound preservative and fresh-keeping powder and a using method thereof.

Background

In the field of food processing and production, the existence of an indispensable preservative and an antistaling agent is essential, the quality of life of people is greatly improved nowadays, the requirement on healthy food is also improved, how to keep the freshness of the food to the maximum degree is an important research direction of the food production industry nowadays, most of the existing antistaling agents are artificially synthesized chemical preparations, and under the condition that the requirement on food health is increasingly remarkable, how to adopt a natural preservative and an antistaling agent becomes an inevitable trend.

Disclosure of Invention

The invention aims to solve the technical problem of providing natural compound preservative and fresh-keeping powder and a using method thereof, wherein the natural preservative and fresh-keeping powder is natural, safe, nontoxic and good in oxidation resistance, and can effectively preserve and keep food.

In order to solve the technical problems, the invention adopts the following technical scheme:

a natural compound antiseptic fresh-keeping powder comprises the following components by weight: 25-35% of rosemary extract, 15-25% of licorice extract, 15-25% of garlic extract, 10-20% of nisin and 10-20% of chitosan.

Preferably, the rosemary extract is prepared by drying and crushing fresh rosemary stems and leaves, and then adding the dried rosemary stems and leaves into an extraction tank to extract carnosic acid and rosmarinic acid.

Preferably, the licorice extract is glycyrrhizic acid.

Preferably, the garlic extract is garlicin, and is extracted by a supercritical extraction method.

Preferably, the prepared preservative and fresh-keeping powder is mixed and dissolved with water according to the proportion of 1-10: 1000mL, and then the meat food and the fresh-cut vegetables and fruits are sprayed for use.

The invention has the beneficial effects that:

the rosemary extract mainly comprises carnosic acid and rosmarinic acid, the carnosic acid is used as an antioxidant, the antioxidant is sprayed on the surfaces of fruits and vegetables to effectively slow down the oxidation speed of the fruits and vegetables, and meanwhile, the carnosic acid can inhibit the oxidative rancidity of meat products caused by the working procedures of heating, mincing, slicing, freezing and the like by slowing down the oxidation of lipid, ferric myoglobin and the like, so that the color and the meat quality of the meat products are effectively kept; the rosmarinic acid has antibacterial, antiviral, antioxidant, and antiinflammatory effects; the licorice extract has stronger oxidation resistance, and the garlic extract allicin has stronger bacteriostatic action and can effectively prevent the breeding of bacteria on the surface of food; the natural compound preservative and fresh-keeping powder prepared by mixing the extract, nisin and chitosan is safe and nontoxic, has good oxidation resistance, and can effectively preserve and keep food.

Detailed Description

The present invention will be further described with reference to the following examples for facilitating understanding of those skilled in the art, and the description of the embodiments is not intended to limit the present invention.

Examples

Uniformly mixing the following powder of each component by weight ratio of 30% of rosemary extract, 20% of licorice extract, 20% of garlic extract, 15% of nisin and 15% of chitosan, grinding for the second time, and sieving to obtain the natural compound preservative and fresh-keeping powder for later use.

Weighing 5g of natural compound antiseptic and fresh-keeping powder, adding 1000mL of purified water, dissolving and mixing uniformly, and spraying the mixture on the surfaces of meat and fresh-cut fruits and vegetables.
