This experiment was investigated on weight loss, vitamin C content, and its relationship to evaluate visual quality during spinach consignment from a viewpoint of consumer. Vitamin C content of spinach leaf, 35.38mg% fresh weight, was 3 times higher than those of stem. Under $20^{circ}C$ of spinach consignment, the spinach was edible in a half day of unpackage and 3 days with package. However, under $10^{circ}C$ of spinach consignment, it was good through 6-7 days with unpackged and 10 days with package. Weight and vitamin C content of stem and leaf in spinach during consignment were closely related to the temperature condition at $20^{circ}C$ than at $10^{circ}C$ in both of package and unpackage. The regression equation of relationship between loss(X) and vitamin C loss(Y) of spinach, during consignment with Package and unpackage at $20^{circ}C$ and $10^{circ}C$ was Y=21.30X+40.32(r=0.69.)
