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

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, in particular to a method for detecting water and fat content in abalone by using low-field nuclear magnetic resonance technology. Background technique [0002] Abalone is a kind of primitive marine shellfish, Molluscs, Gastropoda, Primitive Gastropoda, Baubaceae, single-shelled mollusk, with only half-sided shell, hard and thick shell, flat and wide. Abalone is a traditional and precious ingredient in China, and it is the first of the four seafood delicacies. Now, all abalone-producing countries in the world are developing artificial breeding. China bred variegated abalone seedlings in the 1970s, and artificial breeding was successful, with a large breeding and sales market. At present, abalone is mainly processed into dried abalone, ready-to-eat abalone and canned products. The fat and water content of abalone are important indicators to evaluate its quality and safety. The level of fat content...
