Effect of head space on pasteurized hot filled orange juice in storage

Preservation of food products without the chemical preservation is world need today. This study is divulged on pasteurised Hot-fill orange juice the sequel of ascorbic acid processed water and head space for 90 days during storage at room temperature. 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. Hence concluded that during processing as well as in storage the microbial growth especially Alicyclobacillus could be inhibited by processed water leaving no head space and ascorbic acid fortification.
