Problems solved by technology

However, the main disadvantage of NIR spectroscopy is that reflectance spectroscopy only provides information on the surface layer of the sample
Cannot measure intact samples, easily affected by surface properties

Embodiment Construction

[0028] The specific implementations of the present invention will be described in more detail below with reference to the accompanying drawings and embodiments, so as to better understand the solutions of the present invention and the advantages of various aspects thereof. However, the specific embodiments and examples described below are only for illustrative purposes, rather than limiting the present invention.

[0029] The experimental methods used in the following examples are conventional methods unless otherwise specified.

[0030] The materials and reagents used in the following examples can be obtained from commercial sources unless otherwise specified.

[0031] The specific implementation steps are as follows:

[0032] Sample collection: Collect 20 abalones from different origins, different sizes, and different seasons in different batches. In this way, the moisture and fat content of the abalone can be quite different, and the sample is representative.

Abstract

The invention provides a method for detecting the water content and fat content in abalone through a low-field nuclear magnetic resonance technology. The method comprises the following first step of collecting samples, the second step of carrying out low-field nuclear magnetic analysis on the sample, the third step of measuring the samples, the fourth step of establishing a model, the fifth step of evaluating the model, and the sixth step of measuring the water content and the fat content of the samples to be detected. By means of the method, the water content and fat content in abalone can be measured at the same time, detection is rapid and accurate and free of the influence of the surface feature of abalone, and abalone is not damaged in the measuring process.

Description

Technical field [0001] The invention relates to the field of food detection, and in particular to a method for detecting moisture and fat content in abalone by using low-field nuclear magnetic resonance technology. Background technique [0002] Abalone is a primitive marine shellfish, Mollusca, Gastropoda, Primordial Gastropod, Abalone, and single-shelled mollusk. It has only a half-faced shell with a thick, flat and wide shell. Abalone is a traditional Chinese precious ingredient, the first of the four great flavors. At present, the countries that produce abalone in the world are all developing artificial breeding. China cultivated variegated abalone seedlings in the 1970s. Artificial breeding has been successful and has a large breeding and sales market. At present, abalone is mainly processed into dried abalone, instant abalone and canned products. The fat and moisture content of abalone are important indicators to evaluate its quality and safety. The level of fat content n...
