Study on heat-dehydrating technics of L. barbarum L
The experiment was carried out to investigate the technological condition of heat-dehydration with L. barbarum L. By the experiment, it is sure that the mixture of 0.04% Zn(CHCOO)2 and 0.02% Na2SO3 is the best green protection reagent and soakage in the solution of 0.3% CaCl2 for 20 min can keep the quality of texture.The result of L9(33) orthogonal design showed that soakage in the water of 95℃ for 2 min and heat-dehydration under 85～95℃ is the best technological condition.
