Method for detecting water absorption and retention capacity of soybean dietary fibers

Abstract

The invention discloses a method for detecting the water absorption and water retention capacity of soybean dietary fibers and relates to the field of soybean dietary fiber detection methods. The method comprises the following steps of selecting soybean dietary fiber powder with uniform powder, accurately weighing the selected soybean dietary fiber powder, mixing with water, and adding into a stirring container; uniformly stirring the mixture in the stirring container to form slurry, correcting the levelness of the Bostwick consistence meter by utilizing a leveling screw and a gradienter, thenpouring all the stirred slurry into a sample tank behind a spring door of the Bostwick consistence meter, and measuring the flowing progress of the fluid in the instrument through precise scales on abottom plate of the Bostwick consistence meter, and calculating the water absorption and retention rate of the soybean dietary fibers according to a calculation formula V=30 / L. The method is extremely simple in process step, easy to operate, convenient to implement, high in practicability and capable of rapidly, conveniently and accurately measuring the water absorption and water retention capacity of the soybean dietary fibers, and the problem that the water absorption and water retention capacity of the soybean dietary fibers is difficult to detect in the current industry is solved.

Description

technical field [0001] The invention relates to the field of detection methods for soybean dietary fiber, in particular to a detection method for the water absorption and water holding capacity of soybean dietary fiber. Background technique [0002] Soybean dietary fiber mainly refers to the general term of macromolecular sugars that cannot be digested by human digestive enzymes, mainly including cellulose, pectin, xylan, mannose, etc. Although dietary fiber cannot provide any nutrients for the human body, it has important physiological functions for the human body. Dietary fiber can significantly reduce plasma cholesterol, regulate gastrointestinal function and insulin levels and other functions. Dietary fiber is recognized as the "seventh largest nutrient" by the medical and nutritional circles. Soybean dietary fiber has the characteristics of rich nutrition, unique flavor, safe and convenient consumption, etc., and is the best among dietary fibers; [0003] The soybean...

Problems solved by technology

For the quality control work of production enterprises and the production of application-oriented terminal enterprises, the detection of the water absorption and water holding capacity of soybean dietary fiber needs to shorten the detection time and streamline the detection procedures. For methods that take too long analysis time, complicated procedures or inaccurate judgment results, the method will generally fail. In practical application, it causes great trouble to the enterprise
