Abstract
Abstract This invention resides in the discovery of a fluent food emulsifier concentrate comprising a normally liquid partial glycerol ester food emulsifier vehicle in which is stably dispersed ethoxylated fatty acid esters and solid phase fine crystalline food emulsifier components, said concentrate being mechanically dispersible into a comestible mixture for the emulsification thereof. The present invention is particularly suitable for the preparation of a stable fluid shortening containing the emulsifier concentrate and a liquid edible oil suitable for bread and dough mixtures providing both dough conditioning and anti-staling properties. In an example of the present invention, the fluid concentrate comprises a fluent monoglyceride such as glycerol monooleate admixed with ethoxylated mono- and diglyceride and a solid phase ester emulsifier such as a succinylated mono- and diglyceride, or the alkali or alkaline earth metal salt of an acyl lactylate.
