Using spectrophotometric and light scattering method,the different cleaning water turbidity was measured,and the stability and adaptability of these two test methods were compared;the relationship between cleaning water turbidity and vegetable carried sediment were studied.The results showed that the turbidity of cleaning water can represent vegetables sediment and by light scattering method;the stability of cleaning water was proved to be superior;turbidity test method was not only suitable for leafy vegetables but also fruits vegetables.
