摘要
研究金属离子对番茄汁特征性香气组分及其关键酶活性的影响。建立番茄汁中己醛、反-2-己烯醛、己醇、顺-3-己烯醇和反-2-己烯醇的测定方法,该方法日内和日间精密度分别为2.13%和4.66%;进一步评价Fe^2+、Fe^3+、Cu^2+、Ca^2+、Mn^2+和Na^+对番茄汁特征性香气组分及关键酶活性的影响。结果显示,Fe3+离子钝化番茄汁中醇酰基转移酶,促进番茄特征性香气组分己醛和反-2-己烯醛的积累,使香气活力值之和比未处理组提高了62.1%。因此,添加Fe3+离子有助于番茄汁特征性香气组分积累。
The effects of metal ions on typical aroma components and key enzyme activities of tomato juice were evaluated. A rapid method for the hexanal, trans-2-hexenal, hexanol, cis-3-hexenol, and trans-2-hexenol content in tomato juice was established. The intra-day and inter-day precision of the method were 2.13% and 4.66%, respectively. The effects of Fe^2+, Fe^3+, Cu^2+, Ca^2+, Mn^2+, and Na^+ on the typical aroma components and key enzyme activities of tomato juice were evaluated. Alcohol acyltransferase in tomato juice was inactivated by Fe3+ ions. The Fe3+ ion promoted the accumulation of the characteristic aroma components of tomato, including hexanal and trans-2-hexenal, and increased the sum of odor activity value by 62.1% compared with that of the control. Therefore, the addition of Fe3+ ions help the accumulation of the typical aroma components of tomato juice.
