Outcomes were exhibited the significant reduction of the Alicyclobacillus growth with the addition of an amount of 150mg/lit of vitamin C and head space finishing of thermosetting container. While, initial bacterial count was controlled by ozonated and ultraviolet light processed water. Savor and color impermeability in the pasteurised Hot-fill orange juice were significantly (p < 0.05) pompous by both addition of vitamin C and leaving no head space. While in contrast the non- significant effect on acidity, pH, 0Brix, reducing and non-reducing sugar were observed during the storage.
