A SIMPLE METHOD FOR DETERMINATION OF K VALUE AS AN INDEX OF FISH FRESHNESS |
| |
| Abstract: | A simple method for determination of K value as an index of fish freshness was developed by using anion exchange resin. A series of ATP chemicals from fish was absorbed and seperated and the K value was caculated through the absorbance of different eluting solutions. This analysis is a simple and quick, the recoveries of which was 94.3-104.8%. The relative standard variation of this work was 2.72-3.46%(n=3). |
