  • Patent number: 4752494
    Abstract: A bland, intermediate water activity matrix suitable for use in preparing a thermostable, edible creme, is produced by dispersing Ca.sup.++ ions, caseinate ions, corn syrup, lactose and maltodextrin in water; and heating the dispersion to a temperature sufficient to gel the Ca.sup.++ ions and caseinate ions. The bland, intermediate water activity matrix can be converted to a low water activity thermostable creme by admixing it with modified starch, a fat and an emulsifier, and a flavoring material. The thermostable, edible creme can be incorporated into shelf-stable, ready-to-eat bakery products.
