- 摘要:
- 以绿豆种子为试材，研究了浓度为0.05%、0.10%、0.20%、0.50%的外源氮素（尿素）对绿豆萌发期氮素代谢与品质的影响。结果表明：随外源氮素浓度的逐步升高，产量呈现先增加再降低的趋势，但未达到差异显著水平；可溶性蛋白质、可溶性糖含量呈现先增加后递减趋势；游离氨基酸及硝态氮的含量呈现逐步增大趋势；随着发芽时间的延长，各处理绿豆芽中硝态氮含量均呈降低趋势，但各处理间降低幅度不同；高浓度氮素处理可导致绿豆芽内硝态氮含量严重超标，远高于432 mg/g的食品安全标准。
- Abstract:
- Taking mung beans seeds as materials,the effects of different exogenous nitrogen (urea) 0.05%，0.10%，0.20%，0.50% on nitrogen metabolism and quality during the germination of mung bean seeds were studied.The results showed that with the urea concentration increasing，yield showed the tendency of increase first and then decrease，but did not show significant difference;the contents of protein and soluble sugar tended to increase first and then decrease.The content of free amino acid and nitrate nitrogen showed increasing content.The content of nitrite in mung bean sprouts were decreased with germinating time running，but their ranges were different.The nitrate nitrogen concentration of mung bean sprout were seriously exceeded food safety standard (432 mg/g) in the treatments of high urea application.
