Hydroxypropyl Distarch Phosphate Powder Usage and Synthesis.

The application of hydroxypropyl diastarch phosphate in the production of jelly with hydroxypropyl diastarch phosphate partially replacing agar as a gelling agent for jelly, the elasticity and transparency of the product has a certain effect. However, the indicators are close to the quality of commercially available jellies, and the conformability and cutting elasticity of the products are better.

The test also showed that all with hydroxypropyl dihydroxystarch phosphate instead of agar, transparency and elasticity can still meet the requirements of commercially available jellies, but the texture has a mushy feeling, so it is not applicable. It can be seen that hydroxypropyl diastarch phosphate in the production of jelly partially replacing agar as a gelling agent is feasible.

Hydroxypropyl dihydroxypropyl starch phosphate and hydroxypropyl starch in the jam in the general production of jam with pectin as a gelling agent, which needs to be added 40% to 60% of the sugar to control a certain degree of acidity in order to get the ideal gel.

Hydroxypropyl diastarch phosphate and hydroxypropyl starch gel has a certain transparency and consistency, and their gelling process does not require the participation of sugar. It was found that the cost of jam made from hydroxypropyl di-amyl phosphate and hydroxypropyl starch was greatly reduced, and its flavor, consistency and texture were similar to those of commercially available jams.

However, there is a difference between the products made from hydroxypropyl di-amyl phosphate and hydroxypropyl starch, the former products have good coating performance while the latter products are more tough and have less coating performance than the former.

Uses of Hydroxypropyl Distarch Phosphate.

Hydroxypropyl Phosphoric Acid Double Starch is a modified starch obtained by cross-linking starch molecules through ether bonds or diester bonds.

The introduction of hydroxypropyl, carboxymethyl, phosphate and acetate groups gives it better hydration, forming a uniform and transparent paste in water, increasing viscosity and stability.

Therefore, hydroxypropyl phosphoric acid double starch has good thickening, suspending and stabilizing effects and is widely used in food, pharmaceutical and cosmetic industries.

In addition, prebiotics such as oligosaccharides and inulin can also promote the proliferation of beneficial bacteria such as bifidobacteria in the human intestinal tract, inhibit the reproduction of harmful spoilage bacteria, regulate the intestinal flora, and improve the health functions of yogurt and other foods.

Fat also plays an important role in the flavor and taste of milk, and the fat-soluble vitamins in milk also depend on fat.

Preparation of Hydroxypropyl Distarch Phosphate.

Hydroxypropyl diastarch phosphate is prepared from potato starch by slurry adjustment, cross-linking, esterification, neutralization, washing, drying, sieving and packaging. Through the precise process control system, it improves the deficiencies of common starch, such as poor water retention, stability, etc. It also has the characteristics of heat resistance, low temperature resistance, acid and alkali resistance, and extremely strong adhesion.

Its application effect can completely reach the level of similar products abroad.

And low cost, in addition to a wide range of raw material sources is also one of its major advantages. Realized the use of domestic potato starch as raw materials for the production of high-grade products, effective control of the cost of such products (foreign similar products priced at 20,000 yuan / ton, the price of this product is 9,000 yuan / ton). Specific process steps are as follows:

1), adjust the slurry: in the reaction kettle will be potato starch and accounted for the proportion of potato starch quality of 5-25% of sodium sulfate or sodium chloride with water to modulate the starch slurry into 20-23Be, stirring evenly.

2)、Cross-linking: add 3-3.8% sodium hydroxide to the starch slurry under constant stirring to adjust the pH value to 11-12, and then add sodium trimetaphosphate at 0.2-0.5g/ton of potato starch, stirring for 30 minutes.

3), etherification: add propylene oxide to the above crosslinked starch slurry at 50-70 kg/ton potato starch, raise the temperature to 45-49, and continue the reaction to 21 hours.

4), neutralization: adjust the PH value to 6.0-7.0 with hydrochloric acid at a mass concentration of 8-10% at the end of the above etherification reaction.

5) Wash: Wash with cyclone scrubber.

6)、Drying: firstly, use scraper type centrifugal dewatering machine to dewater to ≤45% moisture, and then use air flow dryer to dry to ≤18.0% moisture.

7) Sieving: 80-100 mesh vibrating sieve is used for sieving.

8)、Packaging: 20-25kg/bag is used to pack the final product.

Product Method of Bulk Hydroxypropyl Distarch Phosphate Powder.

The finished product is obtained by esterifying sodium trimetaphosphate or phosphoryl chloride (≤0.1%) and ethylene oxide (≤10%) with starch.
