The present invention provides improvements in dairy products especially cultured dairy products such as stirred style yogurt. The improvement provides aerated or whipped yogurt products and methods of preparing such improved whipped yogurt products. The improvement resides in part in the post fermentation addition of a hydrated emulsifier blend to cultured yogurt.

Whipped yogurt products and method of preparation

The present invention provides methods for preparing at least pasteurized hydrated emulsifier compositions. The methods for preparing an aseptic hydrated emulsifier comprise the steps of: A. Preparing a hydrated emulsifier blend of lactylated mono- and di-glycerides; B. Treating the hydrated blend to at least pasteurize the blend to form an at least pasteurized hydrated emulsifier blend; and, C. Cooling the at least pasteurized hydrated emulsified blend to refrigerator temperatures forming a cooled pasteurized hydrated emulsifier blend. The hydrated emulsifier described herein is also useful in the aeration of food products such as yogurt, other refrigerated milk products, ready-to-spread frostings, fermented and unfermented soy, rice and nut milk products, beverages, and whipped toppings.

Food products and their method of preparation

The present invention provides methods for preparing at least pasteurized hydrated emulsifier compositions. The methods for preparing an aseptic hydrated emulsifier comprise the steps of: A. Preparing a hydrated emulsifier blend of lactylated mono- and di-glycerides; B. Treating the hydrated blend to at least pasteurize the blend to form an at least pasteurized hydrated emulsifier blend; and, C. Cooling the at least pasteurized hydrated emulsified blend to refrigerator temperatures forming a cooled pasteurized hydrated emulsifier blend. In preferred embodiments, the present methods comprise substeps for preparing the hydrated emulsifier blend of lactylated mono- and di-glycerides, comprising: admixing a first wetting agent emulsifier comprising sodium stearyl lactate with hot water to form a clear mixture; admixing a second emulsifier comprising a blend of lactylated mono- and di-glycerides with the clear mixture; and, maintaining the lactic ester blend of mono- and di-glycerides at about 43&#xb0; C. to 95&#xb0; C. for sufficient time to disperse and hydrate the lactylated mono- and di-glyceride in the clear mixture to form a hydrated emulsifier blend. The hydrated emulsifier described herein is also useful in the aeration of food products such as yogurt, other refrigerated milk products, ready-to-spread frostings, fermented and unfermented soy, rice and nut milk products, beverages, and whipped toppings.

Refrigerated cultured dairy products such as yogurt having enhanced anti-mold stability are prepared by including minute quantities of a cultured dairy ingredient having been cultured with a propionic acid forming culture. The propionic bearing cultured dairy ingredient such as whey is added to a milk base that is then heat treated prior to inoculation and fermentation with a yogurt culture. Premature protein coagulation that can occur during the heat treatment step is minimized by adding minute quantities of a calcium sequestrant to the milk base.
