Example Embodiment

[0022] Embodiment 1: at first 100 kilograms of tapioca starch, 15 kilograms of sodium sulfate and 180 kilograms of water are adjusted into 20-23Be starch slurries in the reactor, constantly stirring, adding mass concentration in the still is 3-4.0% sodium hydroxide solution to regulate The pH value was 11.0, alkalized for 40 minutes, added 4.5 kg of propylene oxide, kept the temperature at 42 ° C and made it react, reacted for 10 hours and added 5ml of epichlorohydrin, continued to react for 25 hours, and added a mass concentration of 8-10% hydrochloric acid solution Neutralize to pH 6.0-7.0, add 200 kilograms of water to the kettle to wash, settle, and then wash in the same way to remove impurities (sodium sulfate, sodium chloride or other chemical residues) to obtain the finished product.

Example Embodiment

[0023] Example 2: The steps are the same as those in Example 1, except that the amount of propylene oxide added in the etherification process is 4.0 kg, and the reaction temperature is maintained at 40°C.

Example Embodiment

[0024] Example 3: The steps are the same as those in Example 1, except that the amount of propylene oxide added in the etherification process is 4.0 kg, and the reaction temperature is maintained at 45°C.

Abstract

The present invention discloses a preparation method of cassawa hydroxypropyl distarch glyceryl ether. It is made up by using water as medium and using cassawa starch, propylene epoxide, epoxy chloropropane, hydrochloric acid and sodium hydroxide as raw material through the processes of mixing paste, alkalization, etherification, neutralization, washing, drying, screening and packaging. It can be used in the products of fruit paste, oyster cocktail, sauce, milk product and flavouring material.

Description

technical field [0001] The invention relates to a method for preparing modified starch, in particular to a method for preparing cassava hydroxypropyl digarch glyceryl ether. Background technique [0002] With the development of the times, people are increasingly aware of the importance of modified starch in the field of food processing, especially in terms of thickening and stability in food applications, anti-aging and increasing transparency, and improving the taste of products. The incomparable advantages of raw starch, especially hydroxypropyl diglyceride, which is widely used in various jams, oyster sauce, sauces, dairy products, soy sauce, etc., and the application effect is relatively good in the market. The products are mainly produced abroad, and their starch raw materials are specially treated and cultivated on a large scale, which ensures the high quality of these products and the stability of quality between batches. The small planting area and large differences...
