以青杏、青转黄杏2种成熟度的鲜杏为原料,采用真空渗透工艺进行护色、硬化,通过单因素试验和正交试验,分别研究了不同护绿剂、护色剂、硬化剂对2种成熟度的鲜杏护绿、护色、硬化效果的影响,以处理后鲜杏的色泽a值、硬度N值为评定指标,最终得出最佳复合护绿剂为ZnCl20.05％、Na2CO30.05％、Vc 0.05％；最佳复合护色剂为Vc 0.125％、柠檬酸0.20％、NaCl 3.0％、NaHSO30.100％、ZnCl20.10％;最佳硬化剂为生石灰,以此工艺参数处理后的鲜杏半成品的色泽与硬度最好.%With the fresh apricot as raw materials, chouse two maturity of green apricot and green-to-yellow apricot. Protect color and sclerosis by the way of vacuum penetration process. Use the single factor experiment and orthogonal test to study the influence of effect on green protected, color protected, sclerosis of different green protected agen,dillenii,Stiffening agent on two maturity of fresh apricot, measure the value a and value N for evaluation index after deal with the fresh apricot. The results show that;the best composite green protection agent is ZnCl2 0.05% ,Na2CO3 0.05% .Vc 0.05%;best composite color protection agent is Vc 0.125% .citric acid 0.20% ,NaCl 3. 0% ,NaHSO, 0. 100% ,ZnCl2 0. 10% ;best hardener for the quicklime. The apricot mad by this process had best color and hardness.
