A method for manufacturing a swelling-inhibited starch, the production method including a step for performing a heating treatment at 55-205° C. on a starch for which the value of M.sub.1−M.sub.0 is within the range from −10 to 20 and setting a breakdown value of a starch paste solution to no greater than 75% of the value before the heating treatment. The heating treatment is performed using closed heating equipment without implementing a moist-heat treatment. M.sub.1: Moisture content (%) of starch before heating treatment M.sub.0: Equilibrium moisture content (%) of starch at normal temperature and normal humidity

A method for producing pregelatinized cereal flour according to the present invention includes: a pregelatinization step of heating a slurry containing 100 parts by mass of cereal flour and 500 parts by mass or more of water under a condition that the temperature of the slurry is 90° C. or more, to pregelatinize starch contained in the cereal flour; and a drying step of drying the slurry from the pregelatinization step to obtain a solid. In the pregelatinization step, the slurry is stirred while heating the slurry. In the pregelatinization step, the slurry is preferably heated under a condition that the temperature of the slurry is 100° C. or more. According to the present invention, there is provided pregelatinized starch that can improve the taste and texture of food and impart aging resistance to the food.

A novel dry mill process for producing pure starch, which can be used as a feed stock for bio tech processes. Corn feedstock is sent through a particle size reduction device, such as a hammer mill, to produce corn flour. The corn flour is screened into a small particle portion (which mainly contains “free” starch from the floury endosperm) and a larger particle portion (which mainly comprises the horny endosperm, germ pericarp and tip cap). The small particle potion is sent to a liquefication and a saccharification process to produce high Be corn syrup. A mud phase (mixture of oil, germ, and any light solid) is centrifuged. The light phase is sent to precoat drum filtration to produce clean corn syrup. Further, a novel wet mill process to produce starch and alcohol is disclosed. A three-section paddle screen can be used to separate starch from grit and fiber.

A process for making a starch-based resin from a starch-based plant feed stock generally comprising the steps of extracting starch content from prepared feed stock, preparing a dried starch from the extracted starch content that may be polymerized in a reactor with a catalytic material, a petroleum-based plastic resin, a quantity of glycerol, and an oil which is high in free hydrogen, and partially cross-linking the polymerized starch with a petroleum-based plastic resin to form a starch-based resin that may be used to produce starch-based film and bag products and other articles of manufacture that have unique degradation properties is disclosed herein.
