Comparison of Non-Enzymatic Gravimetry and Crude Fibre Assays The determination of crude fiber content, whether in the feed or in our regular diet, is of some help, through the use of crude fiber fibrometers or other methods on feeds. The determination of crude fiber content is a good quantitative package for animals, which can improve the quality of animals. For example, dairy cows, control of fiber content can increase milk fat content, and it is also helpful for the determination of our things. The daily intake of a certain amount of human body Crude fiber can help us to digest, but also a great help for patients with diabetes, but excessive intake of the stomach will be unfavorable, so the determination of the fiber content is still helpful. In this paper, two methods of measurement are known, namely non-enzymatic method and the use of crude fiber analyzer method for comparison.
Through the use of non-enzymatic heavy method for the determination of a variety of fruits, the relative standard deviation (RSD) of the total dietary fiber content was measured at 0.77 to 6.01%, which was far less than 10%. This was verified by digital verification. It was found that this method of determination is feasible for the determination of the total fiber content in fruits. Multiple tests on other fruits revealed that the non-enzymatic gravimetric method was used for fruits with high dietary fiber content (≥10% on a dry basis) and less starch content (≤2% on dry basis). Accurate and reliable It is easy to operate, can detect a large number of samples at the same time, the instruments and reagents used are easy to obtain, so it has good applicability. At present, the world chemical analysis mainly adopts this method.
The crude fiber analyzer is based on the current commonly used acid-alkali digestion method to boil the sample, and weight measurement to obtain the crude fiber content of the sample instrument. This measurement method is widely used at present, and the measurement accuracy meets the national standard, and the fiber content in the item to be tested can be accurately determined.
