Embodiment 1

[0023] A fresh walnut kernel film coating agent containing Artemisia annua extract, made of the following raw materials in parts by weight: 20 parts of Artemisia annua, 3 parts of Gardenia, 6 parts of clove, 3 parts of rhubarb, 5 parts of cinnamon, 3 parts of calcium chloride 0.15 parts of potassium sorbate, 0.15 parts of sodium isocitrate, 5 parts of film-forming agent, 1 part of antioxidant, 40 parts of water.

[0024] The film-forming agent is sucrose ester.

[0025] Described antioxidant is ascorbic acid.

[0026] The preparation method of the described fresh walnut kernel coating agent containing Artemisia annua extract is characterized in that, the steps are as follows:

[0027] (1) Grind gardenia, clove, rhubarb, artemisia annua, and cinnamon, pass through a 50-mesh sieve, add ethanol solution, and microwave-assisted extraction; after the extraction is completed, filter to remove the filter residue, evaporate and concentrate the extract, and volatilize to remove ethano...

Embodiment 2

[0031] A fresh walnut kernel film coating agent containing Artemisia annua extract, made of the following raw materials in parts by weight: 30 parts of Artemisia annua, 9 parts of gardenia, 9 parts of clove, 8 parts of rhubarb, 10 parts of cinnamon, and 8 parts of calcium chloride 0.3 parts of potassium sorbate, 0.3 parts of sodium isocitrate, 15 parts of film-forming agent, 3 parts of antioxidant, and 60 parts of water.

[0032] All the other are with embodiment 1.

Embodiment 3

[0034] A fresh walnut kernel coating agent containing Artemisia annua extract, made of the following raw materials in parts by weight: 28 parts of Artemisia annua, 6 parts of Gardenia, 8 parts of clove, 5 parts of rhubarb, 6 parts of cinnamon, 4 parts of calcium chloride 0.2 parts of potassium sorbate, 0.2 parts of sodium isocitrate, 10 parts of film-forming agent, 2 parts of antioxidant, 50 parts of water.

[0035] All the other are with embodiment 1.

[0036] Adopt the fresh walnut kernel coating film agent of the present invention to compare with existing general preservatives, and the storage time is as shown in the following table:

[0037] Table 1-1

[0038]

[0039] It can be seen from the above comparison that the fresh-keeping time of the present invention is increased compared with the existing general fresh-keeping agents.

Abstract

The invention relates to the technical field of food preservation, in particular to a fresh walnut kernel coating agent containing sweet wormwood herb extract and a preparation method of the agent. The coating agent comprises the following raw materials in parts by weight: 20 to 30 parts of sweet wormwood herb, 3 to 9 parts of cape jasmine, 6 to 9 parts of clove, 3 to 8 parts of rhubarb roots andrhizomes, 5 to 10 parts of cassia bark, 3 to 8 parts of calcium chloride, 0.15 to 0.3 part of potassium sorbate, 0.15 to 0.3 part of sodium DL-isocitrate, 5 to 15 parts of filmogen, 1 to 3 parts of anantioxidant and 40 to 60 parts of water. According to the fresh walnut kernel coating agent containing the sweet wormwood herb extract, the extract extracted from the sweet wormwood herb has an inhibition effect on pathogenic bacteria of a microbial disease, and retains the quality of fresh walnut kernels; Chinese herbal medicine raw materials are used as auxiliary materials which have no toxic or side effect and meets food safety requirements; and the fresh-keeping storage period of the fresh walnut kernels can reach 60 to 70 days according to the fresh-keeping method.

Description

technical field [0001] The invention relates to the technical field of food preservation, in particular to a fresh walnut kernel film coating agent containing Artemisia annua extract and a preparation method thereof. Background technique [0002] Walnut is one of the "four major dried fruits" in the world. It has extremely high nutritional value and health care function. Its main role is in the walnut kernel. health has a health care effect. [0003] At present, the walnuts sold on the market are all dry products of walnuts, and there is no such thing as fresh walnut kernels. The so-called fresh walnuts have a higher water content (30-40%). The taste is crisp and sweet, with the inherent aroma of walnuts.
