Abstract
Abstract A sweetened fluid yogurt beverage having a relatively low acidity which will remain stable during storage without separation is provided. A base mix of non-fat milk solids, fat and sugar is provided. The base mix is inoculated with a yogurt culture and is permitted to ferment to provide a sweetened yogurt beverage having from about 0.75% to about 1.25% titratable acidity. The coagulum is broken by agitating the coagulum to provide a fluid yogurt. A stabilizing composition containing xanthan gum and guar gum is added to the fluid yogurt. The stabilized fluid yogurt is then pasteurized to stop any further bacterial fermentation. The fermented fluid yogurt is then homogenized and packaged.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
122 words
A process for manufacture of a fluid yogurt composition comprising providing an aqueous base mix of non-fat milk solids, fat and sugar, pasteurizing and homogenizing said base mix, innoculating said base mix with a yogurt culture, fermenting said base mix to provide a coagulum, breaking said coagulum by agitating said coagulum to provide a fluid yogurt, adding to the fluid yogurt a stabilizing composition in an amount of from about 0.15 percent to about 0.40 percent by weight of said fluid yogurt, said stabilizing composition comprising xanthan gum and guar gum and pasteurizing and homogenizing said stabilized fluid yogurt to stop any further fermentation and to provide a fluid yogurt composition having an extended shelf life with a lessened tendency to separate.
Claim 2
Dependent Claim
122 words
A process for manufacture of a fluid yogurt composition comprising providing an aqueous base mix of non-fat milk solids, fat and sugar, pasteurizing and homogenizing said base mix, innoculating said base mix with a yogurt culture, fermenting said base mix to provide a coagulum, breaking said coagulum by agitating said coagulum to provide a fluid yogurt, adding to the fluid yogurt a stabilizing composition in an amount of from about 0.15 percent to about 0.40 percent by weight of said fluid yogurt, said stabilizing composition comprising xanthan gum and guar gum and pasteurizing and homogenizing said stabilized fluid yogurt to stop any further fermentation and to provide a fluid yogurt composition having an extended shelf life with a lessened tendency to separate.
