| Abstract: | VC consisistence of 11 species fruit were measured by indirect I3s method d absorption spectrotometry for ultraviolet spectrum and also repeated and recoreried triMs.The results showed that the VC consistence was 0.116-10. 872nmol/kg the recovery rate was 92.05%-107.09%. The method was simplified but the accuracy and semsitivity was less difference. The sensitivity was little to 0.025mmol/kg, it is simple immediate method to measure for VC consistence of fresh fruit. |
