摘要: 为降低绿豆芽菜中抗营养物质植酸含量,探究氯化盐对绿豆芽菜植酸降解的影响,研究了KCl、NaCl和CaCl2处理下绿豆芽菜的长势、植酸酶活性及植酸含量的变化,筛选了具有降植酸效果的氯化盐并优化了浓度组合。结果发现,NaCl和CaCl2能够促进植酸降解同时促进绿豆芽菜生长;单因素试验结果表明,1.6 mmol/L NaCl和6 mmol/L CaCl2降植酸效果最佳,且NaCl和CaCl2促进植酸降解作用有叠加效应。响应面法优化得到NaCl、CaCl2浓度分别为1.68 mmol/L和6.40 mmol/L时,植酸含量降低至8.04 μg/株,为对照的10.84%。

Abstract: The objective of this study was to reduce the phytic acid content in germinated mung bean (Vigna radiata (Linn.) Wilczek). The effects of three chlorizated salts on phytic acid degradation were investigated. The growth performance, phytase activity and phytic acid content were studied in germinated mung bean sprouts treated with KCl, NaCl and CaCl2 (2 mmol/L), respectively. The phytase activity and phytic acid content were used to screen the optimal concentrations of chlorizated salts, which have function in reducing phytic acid content. The results showed that all three chlorated salts could promote the growth of germinated mung bean and both NaCl and CaCl2 reduced phytic acid content. NaCl at 1.6 mmol/L and CaCl2 at 6 mmol/L had the best effects on phytic acid degradation. Furthermore, a synergistic effect was found between NaCl and CaCl2, the optimal combination determined by response surface analysis were 1.68 mmol/L NaCl and 6.40 mmol/L CaCl2. Under this condition, the phytic acid content was reduced to 8.04 μg/plant, which was 10.84% of the control.
