Abstract: The soluble solid content，total acid content，color value，sensory evaluation and vitamin content betweenthe new vitamin functional beverage and the competing beverage were compared through thermal preservation to forecastthe new product’s shelf life. The deterioration of the new product was studied and the processing was modified bysubstitute high fructose corn syrup（HFCS）for 40% sucrose. The characteristics of the two beverage product were incommon，and the cost of the new product was relatively lower，implying that the new product has a broad marketprospect.

Key words: vitamin functional beverage；thermal preservation；shelf-life；stability
