The optimizing condition of processing techniques of puffed Caragana korshinskii

It is important to seek an approach to effectively reduce the fiber content and improve palatability and the forage value of Caragana korshinskii for improving the current utilization status of C. korshinskii growing at the forbidden grazing and restgrazing areas. The puffed technique was used to effectively reduce the lignin and cellulose content of C. korshinskii in this study by comparing the nutrients of C. korshinskii. The atmospheric pressure, temperature, the moisture content of raw material, and the cut length were applied to optimize the processing techniques of puffed C. korshinskii in this experiment. The results of this study showed that the 1.0 MPa atmospheric pressure, 170 ℃ temperature, 30% of the moisture content of raw material, 2 cm the lengths was optimal conditions for the puffing C. korshinskii, in which the ADL content of C. korshinskii was the lowest and the digestibility of C. korshinskii was largest.
