Data on the soybean infiltration process utilizing LF-NMR

This paper employs low-field nuclear magnetic resonance (LF-NMR) technology to meticulously analyze and explore the intricate soybean infiltration process. The methodology involves immersing soybeans in distilled water, with periodic implementation of Carr-Purcell-Meiboom-Gill (CPMG) pulse sequence experiments conducted at intervals of 20 to 30 minutes to determine the relaxation time T2. Currently, magnetic resonance imaging (MRI) is conducted every 30 minutes. The analysis uncovers the existence of three distinct water phases during the soybean infiltration process: bound water denoted as T21, sub-bound water represented by T22, and free water indicated as T23. The evolution of these phases unfolds as follows: bound water T21 displays a steady oscillation within the timeframe of 0 to 400 minutes; sub-bound water T22 and free water T23 exhibit a progressive pattern characterized by a rise-stable-rise trajectory. Upon scrutinizing the magnetic resonance images, it is discerned that t..., , , # Data on the Soybean Infiltration Process Utilizing LF-NMR

This data set contains all data for studying the penetration process of soybeans using LF-NMR technology, including the proportions of bound water, sub-bound water, and free water in soybeans under different soaking times, as well as the T2 times corresponding to these three water states.

The NMI20-015V-I nuclear magnetic resonance analyzer‘s (Fig 1) main function was magnetic resonance imaging and relaxation time analysis of water-containing samples. Its resonance frequency (SFOI) was set to 20.826112 MHz. The magnetic field strength was 0.5T±0.08T and the coil diameter was 15 mm. The equipment was equipped with a thermostat to control the temperature at 32±0.01℃ to ensure the accuracy of experimental results. The soybeans were equilibrated to room temperature to measure the relaxation time T2 using the LF-NMR analyzer to generate a Carr–Purcell–Meiboom–Gill (CPMG) pulse sequence. The measurement conditions were as follows...
