Distarch Phosphate Powder Usage and Synthesis.

Phosphate double starch is a kind of modified starch obtained by cross-linking reaction between starch and phosphorylated reagent. GB2760 of China stipulates that it can be used as a thickener in the production of various types of food products according to the appropriate amount of additive use. The introduction of cross-linking bonds in the molecular structure inhibits the degree of water-absorbing and swelling of starch granules, and is able to enhance the aging properties of starch, gel strength of pastes, and thermal stability and other characteristics. Compared with the original starch, phosphate double starch is widely used in frozen food, canned food, and pudding products.

Uses of Distarch Phosphate.

Double starch phosphate is a chemical substance that is toxic and decomposes into pungent fumes when heated.[3] It is often used in the food industry as a thickener, stabilizer, and gelling agent. Double starch phosphate is often used as a thickener, stabilizer and gelling agent in the food industry.

It can increase the viscosity and stability of food, and improve the taste and texture of food.[1] However, due to its toxicity, it is not suitable for use in food. However, the use of double starch phosphate is limited due to its toxicity.

Preparation of Distarch Phosphate.

A process for the preparation of a double starch phosphate ester, comprising the following steps: injecting process water into a feeding tank, putting in raw starch, adjusting the concentration of starch emulsion to 18 boe, and hitting the adjusted starch slurry into a reaction tank;

Add anhydrous sodium sulfate of 0.5% by mass of starch, adjust the pH to 10.0 with sodium hydroxide solution, and subsequently add trichlorophosphorus of 0.15% by mass of starch, and after 40 min of reaction, add dilute hydrochloric acid solution to adjust the pH to 4.5, and abort the reaction to obtain the crude product, and then subsequently enzymatically process it, with the content of ɑ-amylase in the crude product at 300 U/g, for 1 h, at a temperature of 81° C., and a pH 6.5, and then washed in a disk centrifuge, the conductivity of starch milk after washing ≤ 3000 μs/cm, and then squeegee dehydration, and then dried in an air dryer, drying tail air temperature of 35 ℃-70 ℃, drying the finished product of moisture <18%, and then sieved to a fineness of ≥ 99.0%, and then packaged the finished product, finished product net content of 25 kg, and then warehoused.

Product Method of Bulk Distarch Phosphate Powder.

It is made by neutralizing, washing and drying starch milk with sodium trimetaphosphate or phosphoryl chloride, or sodium tripolyphosphate plus sodium trimetaphosphate after cross-linking reaction under alkaline conditions.
