Abstract

The invention discloses a method for measuring soybean oil and water content using low-field nuclear magnetic resonance technology. The specific steps are as follows: measure the oil content of the sample, and measure the water content of the sample; use the low-field nuclear magnetic resonance technology CPMG sequence to measure the soybean sample, and use one-dimensional reverse Lapp Rass algorithm was used to process the relaxation spectrum data of each soybean sample; the actual oil and water content of each soybean sample was corresponding to the relaxation spectrum data; the chemometric method was used for fitting to obtain the prediction model of soybean oil and water content Using the same method to detect and process the soybeans to be tested to obtain the relaxation spectrum data of the soybean samples to be tested; to call the established soybean oil and water content prediction model to obtain the determination of the oil and water content of the soybeans to be tested. The method of the present invention does not require complex pretreatment, does not destroy samples, and conforms to the development direction of green chemistry; it can realize rapid detection and analysis of soybean oil and water content within a few minutes, which is faster and more efficient.

Description

technical field

[0001] The invention relates to the field of detection of soybean oil and water content, in particular to a method for measuring soybean oil and water content by using low-field nuclear magnetic resonance technology. Background technique

[0002] Soybean, also known as soybean, is one of the important economic crops in China. It has high nutritional value. Among the most respected by nutritionists. In addition, soybeans are the most commonly used oil crops in my country. Soybean oil can be obtained from soybeans by pressing and leaching. Therefore, the oil content of soybeans is often used as one of the important criteria for seed selection. At the same time, the moisture content of soybeans has strict requirements in soybean storage. In summary, soybean oil and water content is an important criterion for soybean variety selection.

[0003] In recent years, NMR has been widely used in many fields as an important modern analysis method. According to the pr...
