Abstract: PURPOSE: Provided are RS 4 type crosslinked resistant starch increasing the yield of resistant starch by annealing raw starch and adding a surfactant, and a process for producing the crosslinked resistant starch. CONSTITUTION: The crosslinked resistant starch is produced by the process comprising the steps of: controlling the concentration of the raw starch to be 10-50% and annealing at 10-70deg.C for 1-48 hours; shaking the annealed starch in a constant temperature water tank with 30-50deg.C for 5-20 minutes and adding 0.1-0.5wt% of the surfactant and reacting for 1-16 hours: adding 5-20wt% of sodium sulfate and mixing and shaking for 10-40 minutes and adding 10-20wt% of a crosslinking agent such as sodium trimetaphosphate and sodium tripolyphosphate and shaking for 10-30 minutes and adjusting pH to be 10.5-11.5 with 1N NaOH and reacting for 3-5 hours; neutralizing the resultant starch with HCl and washing with water four times or more and drying in an oven with 30-50deg.C and performing abrasion.
