The quality of grain is largely related to the content of crude fat. Therefore, it is appropriate to use crude fat as an important indicator to evaluate the quality of grain. However, the traditional crude fat detection method has a long test cycle, is complicated to operate, and cannot be quickly detected. , It can no longer meet the needs of modern food production, trading and other testing work, and the advent of fat analyzers establishes a fast and accurate method for identifying food quality. Fat analyzers have also become important instruments for food quality inspection. product.
The fat analyzer is a technique perfected on the basis of Soxhlet extraction, which is comparable to classical Soxhlet extraction and fat analyzers. The traditional Soxhlet extraction method has complex operation procedures. The long operating time, the labor intensity of the test personnel, the energy consumption of water and electricity, etc., and the work efficiency is very low. For example, Soxhlet extraction method requires sample preparation, sample dressing, extraction and drying, result calculation, etc. Steps, and sometimes only 8 h or more are needed for extraction. Therefore, although this method has relatively accurate measurement results, it is inefficient and cannot meet the requirements of modern food testing, especially on-site testing, which is fast and accurate. Therefore, it is being used as a fat analyzer. Replaced by.
The fat analyzer is based on the classical Soxhlet extraction method, so it largely inherits the characteristics of the Soxhlet extraction method with accurate results and meets the relevant standards, but the fat analyzer does not perform the entire measurement process. It takes such a long time to save time, save water, and save electricity. It not only greatly improves efficiency and simplifies operations, but also reduces costs and saves energy. It is a fast and accurate way to identify food quality. Can better meet the daily production and trade transactions in the determination of fat content needs.
