The general category of crude fiber determination methods and analysis of their advantages and disadvantages

The general category of crude fiber determination methods and their advantages and disadvantages Analysis Crude fiber determination is an important indicator in a full food analysis project. Crude fiber has special physiological functions for the human body and is listed as the seventh largest nutrient in the human body. Its analysis and detection technology has received increasing attention. There are three main methods for detecting crude fiber content, namely, acid-base method, neutral detergent method, and acid detergent method. Each method has certain advantages, but also has certain limitations. The crude fiber analyzer is a loading instrument for the determination of crude fiber content. Its measurement principle is the acid-alkali digestion method to operate. Let's take a brief look at the advantages and disadvantages of these methods.
In the three methods of acid-base, neutral detergent, and acid detergent, many countries prefer neutral detergents and acidic detergents, so these countries will use neutral detergents and acidic detergents. The law is listed as a national standard. However, when the neutral detergent method is used, if the protein content of the sample is high, problems such as foaming and difficulty in filtration may occur. For starch-containing samples, amylase removal is also required, which brings great inconvenience to the operation. The acidic detergent method is simple and feasible, and the error of the measured value is small. When the acid-alkali method was used in the determination process, fiber components such as cellulose, hemicellulose, and lignin were degraded to varying degrees, the measured value was lower than the actual cellulose content, and the reproducibility of the results was poor. However, when the crude fiber analyzer is used, the disadvantages of the acid-base hairiness are avoided, and the accuracy of the measurement results is ensured. The crude fiber analyzer uses an accurate concentration of acid and alkali during the measurement, and the sample is decontaminated under specific conditions. Then, ethanol was used to remove soluble substances, and the amount of minerals was deducted after burning at high temperature.
The determination of the crude fiber content is helpful for the adjustment of our euhedral body. By using a crude fiber measurer to measure the crude fiber content, and after making a reasonable diet adjustment, I give extra points for our health.
