枸杞嫩茎叶干制工艺研究

Study on the Drying Process and Technology of Tender Stem and Leaves of Wolfberry

以枸杞嫩茎叶为材料,研究了热风干燥条件下的较优加工工艺参数。结果表明：采用0.04%的Zn（CH3COO）2＋0.02%的Na2SO3的混合液作为护绿剂效果好于锌铜护色;漂烫温度95-100℃、漂烫时间100 s有利于保持色泽和营养成分;用4%的蔗糖溶液浸泡30 min,可以明显改善制品的复水性。

Taking the tender stem and leaf of wolfberry as material, the parameter of excellent processing craft was studied under the hot wind and aridity condition. Result showed that effect of preserving green using mixed liquid of 0. 04% Zn （CH3COO）：and 0. 02% Na：SO3 was better than using Zn and Cu. The optimum bleaching temperature and bleaching time were 95 to 100 ℃ and 100 s, respectively. They were beneficial to maintain color, luster and nutrition. The resetting water could be improved evidently after soaked for 30 min with 4% sucrose solution.
