Abstract
Abstract A rice or other starch based product is provided which is manufactured from either broken rice or whole rice which is first ground and then pressure-formed into rice-shaped pieces. The pressure formed pieces are then heated by exposing them to saturated steam at a super atmospheric pressure above 0.5 psig in an autoclave for a sufficient time to gelatinize a major portion of the starch. After further processing, the rice pieces can be reconstituted by a consumer for consumption.

Claims Analysis
Total Claims: 45
Claim 1
Independent Claim
100 words
A process of manufacturing a starch-based food item comprising the steps of: providing a mixture of ground material, with said material comprising at least about 20% starch by weight of mixture on a dry basis; hydrating said mixture to form a blend, said mixture being hydrated sufficiently to provide pressure formability to said blend; pressure forming said blend to form individual pieces; and heating the pressure formed pieces by exposing said pieces to substantially saturated steam at a super atmospheric pressure above about 0.5 psig in an autoclave for a time sufficient to gelatinize a major portion of said starch.
Claim 2
Dependent Claim
100 words
A process of manufacturing a starch-based food item comprising the steps of: providing a mixture of ground material, with said material comprising at least about 20% starch by weight of mixture on a dry basis; hydrating said mixture to form a blend, said mixture being hydrated sufficiently to provide pressure formability to said blend; pressure forming said blend to form individual pieces; and heating the pressure formed pieces by exposing said pieces to substantially saturated steam at a super atmospheric pressure above about 0.5 psig in an autoclave for a time sufficient to gelatinize a major portion of said starch.
