Problems solved by technology

Therefore, the amount of phosphate added in surimi must be strictly controlled, and the method of determining the phosphate content according to the traditional method not only involves more experimental chemical analysis equipment and chemical reagents, but also needs to destroy the sample; especially the detection time is long and it is difficult to achieve The purpose of rapid quantitative determination in large batches

Embodiment Construction

[0022] In order to implement the present invention smoothly, so that those skilled in the art can fully appreciate the rapid determination of the phosphate content in the surimi and fish cakes, the most important thing is to obtain high-precision phosphate content in the surimi and fish cakes The standard curve, which needs to be done from two aspects:

[0023] On the one hand, several surimi or fish cake samples added with different contents of mixed phosphate and its additives are used as test samples, and the mixed phosphate consumption of each sample is recorded as the phosphate content of the surimi or fish cake sample. actual value. The mixed phosphate is prepared by sodium tripolyphosphate and sodium pyrophosphate in a ratio of 1:1, and the auxiliary agents are sucrose and sorbitol, each prepared by 4% of the total weight of fish paste.

[0024] On the other hand, it is also necessary to reasonably set some parameters in the near-infrared spectrometer that affect the f...

Abstract

The invention relates to a method for fast determination of the phosphate content in hairtail surimi and fish paste. The method provided by the invention comprises the following steps: getting a near-infrared spectrum of the phosphate content in the hairtail surimi and the fish paste and predicting the phosphate content in the hairtail surimi and the fish paste. By adopting the method disclosed by the invention, the problem that the existing method for detecting the phosphate content in the hairtail surimi and the fish paste can not detect a large batch of samples in a fast and non-destructive manner can be solved.

Description

technical field [0001] The invention belongs to the technical field of rapid food detection, and in particular relates to a method for rapidly measuring phosphate content in surimi and fish cakes. Background technique [0002] Hairtail is a kind of economic fish with the highest output in my country's coastal areas. Its meat is tender and fat, delicious, and has high nutritional value. The surimi obtained by pretreatment of fresh hairtail raw materials, meat picking, rinsing, dehydration, stirring and freezing is an intermediate material product with a long shelf life, and is widely used in the production of surimi products such as fish cakes and fish balls. High-quality surimi has the advantages of high protein, low fat, good taste, good whiteness, less miscellaneous spots, and good elasticity. Because of its high protein content, low fat content, easy digestion and absorption, it is very popular among consumers. In the past ten years, the production and export of frozen ...
