Embodiment Construction

[0015] Below in conjunction with embodiment the present invention is described in further detail:

[0016] The method for fresh-keeping and storing nuts food raw materials of the present invention comprises the following specific steps:

[0017] 1) Selection: Use a selection machine to remove impurities, and then select nuts with full particles, complete shape, uniform size, and no mildew on the surface;

[0018] 2) Preparation of coating solution: dissolving the coating agent with a viscosity of 150cp in 0.2% acetic acid-water solution to make a coating solution with a concentration of 2.0% for subsequent use;

[0019] 3) Coating film: soak the above-mentioned selected nut food raw materials in the above-mentioned spare coating liquid, and gently stir to make the coating liquid evenly coated on the surface of the nut food raw materials;

[0020] 4) drying: put the coated nuts food raw materials in a ventilated place to dry naturally, so that the water content is 13%;

Abstract

The invention discloses a high-efficiency and low-cost preservation method of nut food raw materials, which comprises the steps of selecting, preparing coating liquid, coating a film, drying, aeratingpackaging and storage, and performing long-term preservation of the raw materials of the nut food. The fresh-keeping low-cost preservation method is characterized in that the nut-like food raw materials by using the coating liquid, the packaging bag is filled with CO2 or N2 gas with the 0.4-1.2 times of volume of the packaging bag, and then is sealed, so that the fresh-keeping effect of the nut food raw material is good, the effective storage period is long, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of food preservation, in particular to a high-efficiency and low-cost fresh-keeping and storage method for nuts and nuts food raw materials. Background technique [0002] Nuts and nuts are prone to mildew, discoloration, oil leakage and deterioration during storage. Among them, due to the problem of excessive aflatoxin, the export of nuts and nuts has been seriously affected. The toxicity of aflatoxin is one of the most toxic poisons among more than 100 known mycotoxins, among which aflatoxin B1 is the most widely used, most toxic and most carcinogenic. The International Center for Cancer Research has classified aflatoxin B1 as a class I carcinogen. In order to avoid the deterioration of nuts and nuts during storage, in recent years, the widely used storage techniques mainly include: simple storage method, temperature regulation method, radiation storage method, etc. But the effect is poor, the effective ...
