Problems solved by technology

However, the traditional black rice production method has the following disadvantages: the active ingredients of black rice leaves are seriously lost, and the utilization rate of raw materials is low; the water consumption is large, and the remaining wastewater after soaking pollutes the environment; there are many processing links, long soaking time, and low production efficiency; The dyeing effect is not stable enough; because the picking of black rice leaves is limited by seasons, black rice cannot be made all year round, and the processed black rice is easy to deteriorate after long-term storage
