摘要: 利用自行设计的高压交流电场处理新鲜猪肉。结果表明:经1000Hz的频率下5kV/cm的场强作用10s,猪肉浸出汁中谷氨酸含量增加了82.3%,总氨基酸含量增加了14.89%,必需氨基酸含量增加了12.08%;同条件处理20s,谷氨酸含量只增加了28.48%,总氨基酸含量增加了37.56%,必需氨基酸含量增加了38.17%;当频率不变而场强降低到0.5kV/cm时,浸出汁中谷氨酸、总氨基酸及必需氨基酸均有不同程度的增加,但增加幅度不如高场强明显。

Abstract: The effect of high electric field on enhancing pork’s delicate flavour was studied. Results showed that: when the frequency is 1000 Hz and the electric field intensitg is 5kV/cm,after treating 10 seconds the content of Glu on pork’ soaked extract is increased by 82. 3%,and the whole amino acid content increased by 14. 89%,the essential amino acid content increased by l2. 08%;after treating 2O seconds the Glu content is increaed by 28. 48%, the whole amino acid 37. 56%,and the essential amino acid 38. 17%. When the frequency was same as above and the electric field intesisity low to 0. 5% kV/cm,the Glu,whole amino acid and essential amino acid contents were increased by some extent but not so obvious as under high electric fie1d infensity.
