Abstract
Abstract A composition useful for the production of a rehydratable rice product and a method of making such product. The composition includes ungelatinized 90.0 to 99.5 by weight rice flour, 0.2 to 5.0 percent of an aeration agent, 0.1 to 3.5 percent of an emulsifier, and, optionally, up to 1.5 percent by weight of an edible gum. The composition is mixed with water and extruded at temperatures not in excess of 220° F. and dried to make a rehydratable rice product. The extrudate is sized, preferably after drying, into lengths simulating the lengths of rice grains. The product is rehydratable in boiling hot water in 1 to 4 minutes and is particularly suitable for making a rice pudding, in 3-6 minutes.
