摘要
本文研究了渥堆发酵时表层、中层和底层梅干菜中的营养成分、氨基酸组成以及挥发性成分含量的变化.结果表明:渥堆发酵20 d后,表层和中层梅干菜中的粗纤维和可溶性糖含量显著下降(P<0.05);表层、中层和底层梅干菜中的总氨基酸含量、鲜味氨基酸含量和甜味氨基酸含量显著增加(P<0.05),其中渥堆中层梅干菜中的总氨基酸和呈味氨基酸含量最高.挥发性成分分析显示渥堆发酵显著降低梅干菜中烃类、酚类和硫化物等的含量(P<0.05),显著增加酮类、醇类和酯类化合物的含量(P<0.05).其中中层梅干菜中的烃类、醛类、酮类、酯类和硫化物的含量高于表层和底层.本研究表明渥堆发酵有助于提升梅干菜中风味物质的含量.
We studied the variations of the content of nutrient,amino acids,and volatile compounds at the surface,the middle and the bottom of fermented mustard material.The results show that the crude fiber and soluble sugars significantly decreased(P<0.05)at the surface and the middle of fermented mustard material,while the total content of amino acids,especial those umami amino acids and sweet amino acids,significantly increased(P<0.05)after 20 days’fermentation.The volatile compounds,including total hydrocarbons,total phenols and total sulfide compounds,significantly decreased(P<0.05),while the content of total ketones,total alcohols and total esters significantly increased(P<0.05).The content of total hydrocarbons,total aldehyde,total ketones,total esters and total sulfide compounds in the middle were higher than that at the surface and the bottom.Our study demonstrates that fermentation was beneficial to the improvement of the content of flavor compounds in pickled and dried mustard.
