摘要: 研究了柠檬酸、富马酸、酒石酸、琥珀酸4种酸味剂及不同浓度酒石酸溶液浸泡处理对油炸牛干巴中丙烯酰胺含量及其他指标的影响.结果表明,富马酸、酒石酸、琥珀酸均显著降低了牛干巴中丙烯酰胺的含量,其中酒石酸溶液对丙烯酰胺抑制率达到最大,为92.0%;随酒石酸溶液浓度的增加,牛干巴中丙烯酰胺的抑制率下降,酒名酸溶液浓度为0.25 wt%时,丙烯酰胺抑制率最高,达92.5%;牛干巴的水分、还原糖、游离氨基酸、蛋白质含量,也因酸味剂种类的不同及酒石酸溶液浓度的改变而存在显著差异(P<0.05).在油炸牛干巴的生产过程中可以用0.25 wt%浓度的酒石酸溶液浸泡的方法来抑制丙烯酰胺的生成.Abstract: The inhibition of the different kinds of acidulants,such as citric acid,fumaric acid,tartaric acid and succinic acid,and the different concentrations of tartaric acid on the acrylamide of soaking cured beef were studied.The results showed that the fumaric acid,tartaric acid and succinic acid,all of them had significantly effects of reducing the acrylamide contents on cured beef,tartaric acid solution could inhibit 92.0% of the formed acrylamide.With the increase of tartaric acid solution,the inhibitation rate of acrylamide in fried cured beef decreased.When tartaric acid solution concentration was 0.25 wt%,the inhibitation rate of acrylamide was the highest and reached 92.5%.With the changes of the types and concentrations of acidulants,the moisture concent,reducing sugar content,free amino acids and protein content of cured beef had significant differences(P<0.05).In the actual production process could be soaked into 0.25 wt% concentration of tartaric acid solution to inhibit formation of acrylamide before frying.
