Embodiment

[0025] After cleaning and removing the stalk of Agaricus bisporus, cut it into thin slices of about 5mm along the growth direction, place it in the center of the radio frequency coil of the permanent magnetic field, and measure the transverse relaxation time T in the sample by using the CPMG pulse sequence 2 . The equipment parameters are set as follows: main frequency SF=23 (MHz), offset frequency Ol=425557.6Hz, hard pulse 90 degree pulse width P90=14(us), hard pulse 180 degree pulse width P180=30(us), spectrum width SW=200KHz, sampling points TD=828016, repeated scanning times NS=8, repeated sampling time TW=5000ms, echo number NECH=18000. Transverse relaxation time T using inversion software 2 value, such as figure 1 Shown, the transverse relaxation time of free water is 25 ~ 850ms. Then put the Agaricus bisporus slices into the far-infrared drying box for drying, the radiation distance is 150mm, and the radiation intensity is 2.1KW / m 2 . Scan the sample during the dry...

Abstract

The invention relates to a method for representing a far infrared dried agaricus bisporus drying end point on the basis of moisture distribution, and belongs to the field of deep processing of agricultural products. The method comprises the steps that fresh agaricus bisporus slices are selected as raw materials, far infrared drying is performed, the agaricus bisporus slices in the drying process are scanned with a low field nuclear magnetic resonance technique to obtain a moisture distribution inversion chart, and the drying end point is determined according to the size of the free water relaxation area. When the free water relaxation area is zero, the drying process is finished. Compared with a traditional drying oven method for determining the drying end point by measuring the moisture content, the method has the advantages that operation is easy, convenient, visualized and accurate, the drying time is saved, and resource waste is avoided.

Description

technical field [0001] The invention relates to a method for characterizing the drying end point of far-infrared dried Agaricus bisporus based on moisture distribution, and belongs to the field of deep processing of agricultural products. Background technique [0002] Agaricus bisporus (Agaricus bisporus), also known as oyster mushroom and white mushroom, belongs to the genus Basidiomycetes of the fungus genus. It is cultivated on a large scale in Anhui, Jiangsu, Shandong, Henan, Hebei and other provinces in my country. It is the main edible fungus for my country's export earnings. The export volume ranks first in the world. It is rich in nutrients such as protein, amino acid, multivitamins, ascorbic acid and vitamin D, and its nutritional value is 4-12 times that of vegetables and fruits. Fresh Agaricus bisporus is difficult to store after harvesting due to its high water content and delicate texture. Therefore, dehydration processing of Agaricus bisporus can effectively p...
