摘要: 以紫甘蓝为对象,研究真空油炸和常压油炸对其微观结构、生理活性物质和抗氧化能力的影响。结果表明:相比于常压油炸,真空油炸能显著降低紫甘蓝的水分质量分数(P<0.05);真空油炸能使紫甘蓝叶片的结构变得疏松多孔,而常压油炸却使其变得更加致密;两种油炸方式都会降低紫甘蓝的L-抗坏血酸和硫代葡萄糖苷含量,但是在同样的热驱动力条件下,真空油炸对其保留率显著高于常压油炸(P<0.05);随着油炸温度的升高,真空油炸组紫甘蓝的总酚含量逐渐升高,抗氧化能力逐渐增强,且均显著高于同温度下常压油炸组(P<0.05)。综上所述,相比于传统的常压油炸方式,经真空油炸制得的紫甘蓝脆片在微观结构和生物活性方面具有更好的品质。

Abstract: The effects of vacuum and atmospheric frying on the microstructure, bioactive compounds and antioxidant capacity of purple cabbage were studied. The results showed that compared with atmosphere frying, vacuum frying could significantly reduce the water content of red cabbage (P < 0.05). The structure of vacuum-fried samples was more loose and porous, while the structure of atmospheric-fried samples was more dense. Both frying methods could reduce the contents of L-ascorbic acid and glucosinolates in red cabbage. However, under the same thermal driving force, the retention rate of vacuum frying was significantly higher than that of atmospheric frying (P < 0.05). With the increase of frying temperature, the total phenol content and antioxidant activity of the vacuum fried group were gradually increased, and the increments were significantly higher than those in the atmospheric fried group (P < 0.05). To sum up, compared with traditional atmospheric frying, the red cabbage crisp produced by vacuum frying has better quality in microstructure and bioactivity.
