Embodiment 1

[0038] The preparation method of fishmeal amino acid component analysis standard substance of the present invention, the detailed steps of this preparation method are as follows:

[0039] a, impurity removal: first, commercially available fishmeal is screened by a 20-mesh woven sieve to remove impurities;

[0040] b, pulverization: pulverize the fishmeal after removing impurities in step a, and obtain the fishmeal with a fineness of 80 mesh after pulverization;

[0041] c. Degreasing: soak the fishmeal obtained after the pulverization in step b into the solvent anhydrous ether for 12 hours, fully stir every 4 hours during the soaking process, filter after soaking, and filter out the solvent anhydrous Ether;

[0042] The fish meal obtained after filtering for the first time is soaked for the second time according to the same soaking method, filtered after soaking, and the solvent anhydrous ether is filtered off to obtain degreased fish meal;

[0043] d, drying: the fish meal ...

Abstract

The invention discloses a preparation method of a fish meal amino acid component analysis standard substance. The preparation method comprises the following steps: removing impurities of fish meal, and smashing the fish meal after the impurities being removed; adding the smashed fish meal into a solvent, soaking, and degreasing; successively naturally drying and baking the degreased fish meal, andobtaining a fish meal sample; uniformly mixing the fish meal sample, sampling the mixture, and detecting the uniformity; and re-drying the uniformly-mixed fish meal sample, sub-packaging, deactivating the sub-packaged sample in an irradiation manner, finally vacuum packaging the sample, and storing at -20 DEG C. The preparation method of the invention is used for preparing the fish meal amino acid component analysis standard substance, so that the key problems in the prior art can be solved, the blank of no fish meal sample amino acid standard substance in China can be filled, and a foundation is set for improving the research level of the standard substance in the aspects of public health, food, environment and the like in China.

Description

1. Technical field: [0001] The present invention relates to a kind of preparation method of standard substance, particularly relate to a kind of preparation method of fishmeal amino acid component analysis standard substance. 2. Technical background: [0002] Fishmeal is rich in protein, among which the combination of amino acids is reasonable, rich in content and high in nutritional value, so it is widely used as feed. However, unscrupulous merchants mix low-priced high-protein raw materials such as feather meal, leather meal, blood meal, and meat and bone meal into inferior products, which affects the quality of fish meal, thereby affecting the growth and development of poultry and livestock and the quality of meat. With the improvement of people's awareness of the quality and safety of food raw materials and the growing pursuit of quality of life, the detection of food raw materials has attracted more and more attention from relevant departments. For the quality control ...
