Animal protein such as fishmeal should not contain crude fiber, but according to the current production process of fishmeal and general acid-alkali treatment crude fiber side set method, there will still be a small amount of crude fiber in normal fish meal. The problem lies in crude fish meal There is no clear standard for the content range. This has brought difficulties to monitoring, trading, etc. Therefore, this paper has determined more than 10 kinds of fishmeal, and comprehensively related literature to do a preliminary study.
Considering the results of the crude fiber tester and the literature values, it can be considered that the crude fiber content of most normal fishmeal does not exceed 1.5%. Considering the currently used acid-base treatment side method, there is a large error between laboratories. It is also feasible to use the number 2 as the limit value. However, the crude fiber content in fishmeal greater than 2% can be initially identified as a rare fish meal, and should be combined with other detection methods to further confirm.
Crude fiber as an important indicator to identify whether fish meal is doped with plant protein or other fillers is now commonly used in fish meal inspection. Therefore, it is necessary to do further research. The crude fiber analyzer is used to determine the crude fiber content of various items. The instrument's accuracy in the research work can not be underestimated and can fully meet the research needs.
