Problems solved by technology

Acetylated distarch phosphate is very popular due to the above advantages and low cost, but at present, similar domestic products generally have shortcomings such as poor transparency and poor water retention capacity, and many manufacturers require to simplify the process and save production costs. The modified starch used must have the characteristics of cold water gelatinization, which are not available in the current domestic similar products

Embodiment 1

[0029] First, 100 kg of waxy starch, 10 kg of sodium sulfate, and 180 kg of water were adjusted into a 20-23Be starch slurry in the reactor, stirring continuously, and 3-3.8% sodium hydroxide solution was added to the kettle to adjust the pH value to 11.5, and 0.06 Kg of sodium trimetaphosphate, heat up to 45°C, react for 4 hours, cool down to 20°C, adjust the pH value to 8.5-9.0 with 8-10% hydrochloric acid, add 4.5 kg of acetic anhydride, keep the temperature at 20±1°C to react, During the reaction process, continuously add 3-3.8% sodium hydroxide solution dropwise to maintain a pH value of 8.5. After the addition of acetic anhydride, continue to react for 1 hour, add 8-10% hydrochloric acid solution to neutralize to a pH value of 6.0-7.0, and pour into the kettle Add 200 kg of water to wash and settle, and then wash and settle in the same way to remove impurities (sodium sulfate, sodium chloride or other chemical residues) to obtain the initial product of acetate starch, and...

Embodiment 2

[0031] The steps are the same as in Example 1, except that the pH value of the esterification process is maintained at 8.0, and the reaction temperature is maintained at 20±1°C.

Embodiment 3

[0033] The steps are the same as in Example 1, except that the pH value of the esterification process is maintained at 8.5, and the reaction temperature is maintained at 25±1°C.

Abstract

The present invention discloses a kind of pregelatinized acetylated distarch phosphate and its preparation method. It is made up by using water as medium and using waxy starch, acetic anhydride, hydrochloric acid, sodium hydroxide and sodium trimetaphosphate as raw material through 13 processes of mixing paste, alkalization, cross-linking, esterification, neutralization, washing, drying, screening, mixing paste, pregelatinizing, pulverizing, screening and packaging. It can be used as thickening and stabilizing agent in the flavouring material and snack food, etc.

Description

technical field [0001] The invention relates to a modified starch and a preparation method thereof, in particular to a pregelatinized acetylated distarch phosphate and a preparation method thereof. Background technique [0002] In recent years, with the increasing pace of people's life, various sauces and leisure foods have emerged as the times require, and the market scale is increasing. Such products must be added with modified starch to thicken, retain water, and expand. , which requires that the modified starch must have strong water retention capacity, high viscosity, strong transparency and other advantages. Acetylated distarch phosphate is very popular due to the above advantages and low cost, but at present, similar domestic products generally have shortcomings such as poor transparency and poor water retention capacity, and many manufacturers require to simplify the process and save production costs. The modified starch used should have the characteristics of cold ...
