Technical Field

The invention belongs to the field of food storage, and relates to a food protective agent based on a folium artemisiae argyi extract and application thereof.

Background

The storage of food such as grains, agricultural and sideline products and the like is a great problem in daily life, for example, the grains such as wheat, rice and the like can be mildewed and grow insects in the storage process, and further, a great deal of loss of the grains is caused; other agricultural and sideline products such as beans, corns and the like can also generate insects in the storage process, so that the phenomenon of empty shells is caused.

At present, the common methods for preventing and controlling insects and mould in the food adopt methods of fumigating with toxic agents or controlling temperature, humidity, oxygen deficiency management and the like, although some effects are achieved, the methods cannot be eradicated, and meanwhile, the method also requires that a grain depot is sealed, has high cost and is not suitable for being used in families and common small-sized grain depots. Inorganic phosphorus and organic phosphide are used as a protective agent, but the phosphide is a highly toxic chemical component, so that the aim of preventing insects is fulfilled by spraying the inorganic phosphorus and the organic phosphide, and toxic residues are caused, and the content of phoxim in 1 kilogram of wheat flour is 0.19527mg according to detected data, so that the health of a human body is influenced.

Therefore, the development of a new non-toxic and non-residue food protective agent is a problem to be solved urgently.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides a food protective agent based on folium artemisiae argyi extract and application thereof.

In order to solve the problems, the invention firstly provides a food protective agent based on folium artemisiae argyi extract, and the main component of the food protective agent is the folium artemisiae argyi extract.

The preparation method of the food protective agent based on the folium artemisiae argyi extract comprises the following steps:

cleaning folium artemisiae argyi, crushing, adding distilled water for soaking, standing at normal temperature, heating to 90-98 ℃, preserving heat to obtain a water-oil mixture, centrifuging and taking an oil layer to obtain an folium artemisiae argyi extract for later use; mixing folium Artemisiae Argyi extract and adjuvants, granulating by wet method, naturally drying, and packaging solid granules to obtain the final product. Further, the mass ratio of the folium artemisiae argyi to the distilled water is 1: 28.

Further, the standing time is 2-3 h.

Further, the heat preservation time is 8-10 h, distilled water needs to be supplemented during the heat preservation period, and the water level of the distilled water is always kept near the initial water level.

Further, the auxiliary materials are mulberry leaf powder, corn starch or wheat starch.

Further, the mass ratio of the folium artemisiae argyi extract to the auxiliary materials is 1: 6-8.

Further, the package is a non-woven fabric bag package, and each 6-10 g of the non-woven fabric bag package is one bag.

The invention also provides an application of the food protective agent based on the artemisia leaf extract in food storage, wherein the food protective agent is used for preventing the food and agricultural and sideline products from being vermin, and the specific usage is that a bag of the food protective agent is placed in 100kg of food, so that the vermin can be prevented for 12 months.

The invention has the beneficial effects that:

(1) the food protective agent based on the folium artemisiae argyi extract is prepared on the basis of pure natural plants, and has the advantages of fragrant smell, lasting effect and long storage time; meanwhile, after the water-saving agent is used, the water-saving agent can be automatically decomposed when meeting air, water and the like, and cannot pollute the land and water.

(2) The food protective agent based on the folium artemisiae argyi extract is simple in preparation method and low in cost, is non-toxic and non-residue, does not cause secondary pollution, and has a good application prospect in storage of agricultural and sideline products.

(3) The food protective agent based on the folium artemisiae argyi extract is prepared into particles, so that the food protective agent is convenient to use and transport, and the sustained-release emulsion component can keep the drug effect more durable.
