The present investigation was conducted to study the true retentions of α-tocopherol, tocotrienols and β-carotene in crown daisy, unripe hot pepper, onion, garlic, and red pepper as affected by various domestic cooking methods, those were, boiling, baking, stir-frying, deep-frying, steaming, roasting, and microwaving. Fatty acid compositions were determined by GC, and HPLC were used for quantification of α-tocopherol, tocotrienols, and β-carotene. True retentions of α-tocopherol in cooked foods were as follows: boiling (77.74-242.73%), baking (85.99-212.39%), stir-frying (83.12-957.08%), deep-frying (162.48-4214.53%), steaming (45.97-179.57%), roasting (49.65-253.69%), and microwaving (44.67-230.13%). Similarly for true retention of β-carotene were: boiling (65.69-313.75%), baking (71.46-330.16%), stir-frying (89.62-362.46%), deep-frying (178.22-529.16%), steaming (50.39-240.92%), roasting (73.54-361.47%), and microwaving (78.60-339.87%).
本研究旨在探讨不同家庭烹饪方法（煮、烤、炒、炸、蒸、焙烤和微波加热）对茼蒿、青椒、洋葱、大蒜和红辣椒中α-生育酚、生育三烯酚和β-胡萝卜素真实保留率的影响。采用气相色谱法测定脂肪酸组成，高效液相色谱法对α-生育酚、生育三烯酚和β-胡萝卜素进行定量分析。烹饪食品中α-生育酚的真实保留率如下：煮（77.74 - 242.73%）、烤（85.99 - 212.39%）、炒（83.12 - 957.08%）、炸（162.48 - 4214.53%）、蒸（45.97 - 179.57%）、焙烤（49.65 - 253.69%）和微波加热（44.67 - 230.13%）。β-胡萝卜素的真实保留率情况类似：煮（65.69 - 313.75%）、烤（71.46 - 330.16%）、炒（89.62 - 362.46%）、炸（178.22 - 529.16%）、蒸（50.39 - 240.92%）、焙烤（73.54 - 361.47%）和微波加热（78.60 - 339.87%）。
