Abstract

PURPOSE:To obtain an oxidized starch having an improved flavor and suited for food in all respects by adding a specified alkalified lower alcohol to an oxidized starch, filtering said alcohol from the mixture and adjusting the pH of the product to a slightly acidic or neutral pH value. CONSTITUTION:An alkalified 2C or higher lower alcohol is added to an oxidized starch produced by reacting starch with an oxidizing agent. After the mixture is kept at a temperature <= the b.p. of said alcohol, said alcohol is filtered from the mixture and water is added to the product. The pH of the product is adjusted to a slightly acidic of neutral pH value and the product is filtered and washed with water to obtain the purpose oxidized starch. Although the temperature of the alkalified lower alcohol used may be in the range of room temperature to the b.p. of the alcohol, it is preferably 40-60 deg.C. Although the length of time for which the mixture is held at said temperature is 2hr or longer, a length of 3-5hr is the most efficient.

(Function) The present invention is characterized in that an alkaline lower alcohol having 2 or more carbon atoms is used to improve the flavor of oxidized starch. When removing starch, treating starch with hot ethanol is recommended as described in R.W.
and Industry of Starch” No. 260
This is a well-known fact that has been practiced for a long time, as described in the page. However, even when this is used to improve the flavor of oxidized starch, it is somewhat effective, but not completely. Only the use of alkaline lower alcohols having 2 or more carbon atoms will completely improve the flavor.

A further advantage of the present invention is that not only the flavor of oxidized starch can be improved, but also the transparency of the oxidized starch gelatinization liquid (paste or gelatinization solution) can be increased. Generally, the gelatinized liquid of cereal starch (wheat starch, corn starch, etc.) is not transparent and is cloudy.

A gelatinized solution of oxidized starch produced from cereal starch is transparent at high temperatures, but becomes translucent and loses transparency when cooled. In the present invention, the gelatinized liquid of oxidized starch treated with an alkaline lower alcohol is not only transparent at high temperatures, but also maintains its transparency even when cooled, and is extremely excellent in forming a clear gelatinous liquid. . The high transparency of this paste liquid is a great advantage when used in food products.
