不同品种萝卜芽苗菜生长过程中活性成分的变化研究

萝卜芽苗菜是抗癌蔬菜,生长过程中能形成具有抗癌功效的异硫氰酸酯等生理活性物质,在我国食用量相对较多。为探究不同品种萝卜芽苗菜在生长过程中活性成分的变化,为芽苗菜的工业化生产提供理论依据,本文对长春白萝卜、潍县青萝卜、抚顺红萝卜这三个品种萝卜芽苗菜生长过程中的生长情况、活性成分含量及抗氧化能力的变化进行了研究。结果表明,三个品种萝卜芽苗菜中潍县青萝卜芽苗菜的生长能力最强;三个品种芽苗菜抗坏血酸和花色苷含量均呈现先增加后减少的趋势,其中潍县青萝卜芽苗菜中抗坏血酸含量最高,抚顺红萝卜芽苗菜中花色苷含量最高;三个品种的总酚含量差异不显著,但都呈现下降的趋势。硫苷、异硫氰酸酯含量均在第3 d时达到最高,且潍县青萝卜芽苗菜的含量最高,分别达15.63μmol/g FW和2.8 mg/g;抚顺红萝卜芽苗菜的DPPH·清除率和还原能力最强。

Study on the Changes of Active Components of Different Radish Sprouts Varieties during Growth

Radish sprouts are anticancer vegetables,which can form isothiocyanates and other physiological active substances with isothiocyanates effects in the growth process,and the consumption of which is relatively large in China.In order to explore the changes of active compounds of different varieties of radish sprouts,and to provide theoretical basis for the industrialization of sprouts,the growth,content of active compounds and antioxidant capacity of three varieties of radish sprouts from Changchun white radish,Weixian green radish and Fushun red radish were investigated in this study.The results showed that Weixian green radish sprouts grew best.The contents of ascorbic acid and anthocyanin in sprouts of three cultivars increased firstly and then decreased during growth.The highest ascorbic acid and anthocyanin content was observed in Weixian and Fushun radish sprouts,respectively.There was no significant difference in total phenol content among the three cultivars,but all of them showed a decreasing trend.The highest glucosinolate content and isothiocyanate formation was found in 3-day-old Weixian radish sprouts,reaching 15.63 mol/g FW and 2.8 mg/g,respectively.Fushun radish sprouts had the best DPPH·scavening and reducing capacity.
