Problems solved by technology

The main reasons for these problems are that my country does not pay enough attention to rice varieties for special rice noodle processing, and the research and development is insufficient. There are very few high-amylose rice varieties that are suitable for processing high-quality rice noodles. Without the demand for rice noodle processing, the price of rice noodle rice also remains high, leading unscrupulous businessmen to take risks

On the other hand, most of the local purple-black rice varieties in my country are glutinous rice. Even if there are local purple-black rice sticky rice varieties, or even a new purple-black rice sticky rice variety bred, not only the yield is low, but also due to insufficient amylose content, it is difficult to To meet the demand for high-quality raw materials in purple and black rice noodle processing
