Orthogonal test optimization Coix chinensis Tod polysaccharide leaching process conditions

摘要

Based on preliminary studies to optimize the ultrasonic extraction of polysaccharides Coix chinensis Tod. conditions using orthogonal test method, the test results showed that: In order to obtain a higher extraction rate, optimization of process parameters for each factor A_3B_3C_2D_1, namely ultrasonic temperature 55°C, extraction time 50min, ultrasonic power 280W, solid-liquid ratio of 1:10, in this condition polysaccharide extraction rate 2.158%. This method can provide a basis for future reference and process scale industrial applications.
