| Abstract: | Phosphate content in frozen surimi and frozen surimi-based products was determined.The best coloured conditions and characteristic absorption peak of phosphate were determined by using spectrophotometer.The characteristic absorption peak of Phosphate was at λ=825 nm.The Phosphate /ABS Standard equation was y=0.006x-0.005.A good linear relationships(R2=0.999) was found within 0.8 μg~100 μg of Phosphate concentration.The Phosphate rate of recovery was 90.78%~94.00% and RSD was 1.38%~4.01%.The lowest detection limit of was 83.5 mg/kg.This method of detection was easy and suit for use to detect phosphate in frozen surimi and frozen surimi-based products. |
