Claim:
1. A method of making a modified starch product, comprising: providing a dry starch; adding water to the dry starch to make a slurry; adding a non-sodium, chloride salt to the slurry; raising a pH of the slurry with a non-sodium alkali to make an alkaline slurry; hydroxypropylating the starch by adding propylene oxide to the alkaline slurry, to result in a hydroxypropylated starch slurry; reducing the pH of the hydroxypropylated starch slurry with an acid, to make a reduced pH slurry; and drying the reduced pH slurry to recover the modified starch product, wherein the modified starch product comprises hydroxypropylated starch and includes a salt residue from the non-sodium, chloride salt, wherein no wash step is applied to the modified starch product, thereby retaining the salt residue in the modified starch product, and wherein the modified starch product has gelatinization onset, peak and end temperatures that are at least 10° C. higher than gelatinization onset, peak and end temperatures of a conventionally hydroxypropylated starch made using a sodium alkali, a sodium salt, and a washing step to remove the sodium salt.
