摘要:
为探索烹调中油的添加对绿叶菜的抗氧化性保存、感官接受度以及二者间联系的影响,以芥蓝和菠菜为实验材料,测定在烹调中添加不同量的油、盐后水溶性抗氧化物质和ORAC、DPPH和FRAP三种抗氧化能力指标的保存效果,同时评定蔬菜样品的感官接受性。结果表明,盐的添加对抗氧化物质的保存有不利影响,而油的添加对其无显著影响。添加0.5g盐和2.5g油的处理组抗氧化成分和抗氧化能力保存效果较好,且符合少油少盐要求,且感官实验表明该处理条件下口感接受度良好。

Abstract:
Oil and salt may have impact on anti-oxidant capacity retention, sensory acceptance green and the relationship between these indicators of green leafy vegetables. The water-soluble antioxidants and 3 anti-oxidant capacity indices, namely ORAC, DPPH and FRAP, were measured for Chinese kale and spinach during the cooking process by added different levels of oil and salt. The sensory acceptance of vegetable samples was also evaluated. The results showed that salt had an adverse impact on the retention of antioxidants, while oil had no significant effect. When adding 0.5 gram of salt and 2.5 gram of oil to vegetables, the antioxidants and anti-oxidant capacity preserved best. Moreover this cooking method was most acceptable and met the dietary pattern of less fat and salt.
