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.

• 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。
