Abstract
An aqueous dispersion containing both acidic and basic proteins and gives better foaming, gelling and emulsion properties than solutions of acidic proteins alone. The basic protein may be made by modifying an acidic protein. Improved aerated products such as meringues and nougat may be made using the solutions.
Claims14
An edible aqueous dispersion capable of forming a foam, a gel or an emulsion comprising at least one non-aqueous phase selected from the group consisting of air, an edible lipid and an edible protein matrix, and an aqueous phase, wherein the aqueous dispersion contains at least one edible globular acidic protein having an isoelectric point of less than 7 and at least one edible basic protein, wherein the basic protein has an isoelectric point of at least 9.5 and a molecular weight of at least 4,500, and wherein the ratio of the concentration of the acidic protein to the concentration of the basic protein is from about 25:1 to 5:1.
An edible aqueous dispersion capable of forming a foam, a gel or an emulsion comprising at least one non-aqueous, insoluble phase selected from the group consisting of edible lipids and an aqueous phase containing at least one edible globular acidic protein having an isoelectric point of less than 7 and at least one edible basic protein, said basic protein having an isoelectric point of 9.5 and a molecular weight of at least 4,500, the ratio of the concentration of the acidic protein to the concentration of the basic protein being from about 100:1 to 5:1, said non-aqueous phase further comprising air, said dispersion defining cells containing said air, each of said cells being surrounded by a cohesive film formed of said lipid, said acidic protein, and said basic protein, the concentration of said acidic protein being at least 0.5%.
