| 摘要: |
| 以新鲜“米邦塔”仙人掌茎片为原料，利用正交试验对仙人掌原汁的最佳护色条件和工艺进行了研究。结果表明：在85～90 ℃下，仙人掌在0.35 g/L醋酸铜溶液中热烫12 min后，再用1.0 g/L L-抗坏血酸和0.3 g/L柠檬酸进行协同护包，护色效果最好。 |

| Abstract: |
| With fresh Opuntia Milpa Alta as raw material,the optimum conditions were researched for keeping cactus juice green by orthogonal test.The result showed:The stalks of cactus were put into the 0.35 g/L copper acetate at 85-90 ℃ for 12 min,then added 1.0 g/L of Vitamin C and 0.3 g/L of citric acid for keeping green. |
