Sweetened Plain and Flavored Carbonated Yogurt Beverages

Abstract

Sweetened plain and strawberry-flavored carbonated yogurt beverages without free whey were developed. Yogurts, after blending with a 12% sucrose solution and additionally with flavor extract, were carbonated under .5 kg/cm2 at 4°C. Sweetened flavored yogurt beverages contained 15.5% total solids, 2.8% protein, 1.5% fat, .5% ash, and 10.7% carbohydrates.Carbonation of chilled sweetened plain yogurt beverages at .5kg carbon dioxide/cm2 at 4°C retarded acid development during cold storage with excellent quality being maintained in the product for 4 mo at 4.4°C. Sweetened plain noncarbonated yogurt beverage controls were unacceptable within 30 days.A consumer acceptance test statistically conducted with strawberry-flavored carbonated yogurt beverages showed that 89.8% of the respondents liked the product and 5.1% disliked it. A hydrolyzed whey concentrate as a replacement for the 12% sucrose solution produced less acceptable, flavored carbonated yogurt beverages.
