摘　　要：以苹果为试材,选用氯化钠、氯化钙、柠檬酸、EDTA-2Na、异抗坏血酸钠为试剂,采用响应面法对苹果片干制过程中的褐变进行了护色研究。结果表明:氯化钠1.05%、氯化钙0.63%、柠檬酸0.94%、EDTA-2Na 0.16%、异抗坏血酸钠1.65%为最优护色工艺参数。Used apple as material,and NaCl,CaCl_2,citric acid,EDTA-2Na as test agent,response surface methodology (RSM)was used to study non-sulfur colour-protection technology during drying of apple pieces.The results showed that the optimal non-sulfur colour-protection compound formula was NaCl 1.05%,CaCl_2 0.63%,citric acid 0.94%,EDTA- 2Na 0.16%and sodium isoascorbate 1.65%.
