Rice is a food with starch as the main ingredient, and there are two starch types in rice, namely amylose and amylopectin. The content of amylose is one of the important indexes that determine the taste quality of rice, and it is also an important factor that affects the sensory quality and processing characteristics of food. Therefore, it is of great practical significance to establish a sensitive, reliable and simple amylose determination method. The traditional rice amylose content determination method is generally very complicated, the operation procedure is very cumbersome, and the detection accuracy is not high, but the widely used amylose content meter has made a large improvement in these aspects, is a kind of rice The simplified method for the determination of amylose content is also a reliable method of detection.
Using pre stretching technique, to use a considerable effort and available for industrial, commercial, domestic, agricultural and other packaging protection and waterproof, dust proof, moisture proof. Packaging material surface layer is not easy to stick dust, clean health. Stretch Film roll, after using the universal recycling equipment can be used in 100% recycling plant. Packing plastic wrap can reduce environment pollution, but also save the cost of recycling packaging.

In the past, rice amylose content was determined and the error caused by human factors was always unavoidable. For example, the sampling was not performed according to the regulations, that is, the samples were mixed and the sampling was not uniform; when the dispersion was added, the amount of alkali was inconsistent with the time; When the coloring solution is used for constant volume, it does not operate according to regulations, etc., and it easily causes measurement errors, resulting in a deviation between the measurement result and the actual result. The use of amylose content meter instrument method to determine the amylose content of rice, one of the biggest advantage is to avoid the interference of human factors, coupled with the advanced nature of the instrument, measurement efficiency and measurement accuracy are obvious Improved, very efficient and convenient.
Amylose content meter as a simplified method for the determination of rice amylose content makes the determination of amylose content in rice more and more simple and does not need to be limited by many factors. In addition, the application of amylose content meter, It is conducive to the formation of a unified and reliable measurement standard, and promote the standardization of rice quality inspection. Over the past few years, as the utilization value of amylose has been further reflected, the application of amylose content meters for the cultivation of high-amylose maize and other crops has also become an important part of agricultural breeding. Therefore, the application of amylose content meter has also been applied. More and more extensive.
