摘要: 本文研究表明:碎核桃仁在加速氧化试验过程中,过氧化值和酸价持续不断增加;充氮包装和真空包装在防止单宁和维生素E含量减少方面与对照差异不显著,但是通过提高超氧物歧化酶(SuperoxidedismutaseSOD)和保持较高过氧化氢酶(CatalaseCAT)的活性,达到延缓核桃仁过氧化值和酸价上升的速度。

Abstract: The results showed that the fragment walnut kernel’s peroxide value and acid value are increasing in the time of accelerated oxidation. The package of nitrogen (N 2 ) or vacuum has no marked difference with the contrast in preventing the quantity of tannin or vitamin E decreasing, but they can delay walnut kernel’s peroxide value and acid value increasing by increasing the superoxide dismutase (SOD) activity and keeping high catalase (CAT) activity.
