Abstract
Abstract The invention encompasses intermediate, starch-containing products in which the starch thickening capacity is inhibited by an aqueous dispersant system. These intermediate products can be readily converted into a starch thickened end-product by combining the intermediate product with additives which dissipate the inhibitory effect of the aqueous dispersant. The intermediate products may be provided as a concentrate which contains cold-water swelling starch granules suspended in an aqueous media adapted to effectively maintain the starch granules in an unswollen form. The intermediate products may be suitably formulated with all the desired recipe ingredients except the amount of water needed to convert it into a starch thickened end-product.
