Abstract:
modified starch, also known as modified starch or modified starch, is based on the original characteristics of the original starch, in order to adapt to the modern industrial production process or quality requirements and improve its performance and expand the scope of application, the use of physical methods, chemical methods or biological methods and other treatment methods, improve the natural properties of starch, increase its performance or the introduction of new characteristics and the preparation of starch derivatives. According to the "national food safety standards for food additives," the use of modified starch in table A2 allows the use of 13 "acetate starch, phosphate double starch, oxidized starch, acidified starch, acetylated distarch phosphate, hydroxypropyl starch, hydroxypropyl distarch phosphate, acetylated distarch adipate, oxidized hydroxypropyl starch, aluminum octenyl succinate starch, phosphorylated distarch phosphate, sodium starch phosphate, sodium carboxymethyl starch", and the amount of use is not limited. Combined with the product characteristics and production requirements of flour improver, the commonly used modified starch is hydroxypropyl distarch phosphate, phosphate double starch and oxidized starch. In this paper, the production of phosphate double starch and its use as a flour improver in the Help flow dilution were studied.

Abstract:
The invention discloses a preparation process of hydroxypropyl distarch phosphate, which comprises the following steps: Step 1: injecting process water into a feeding tank, feeding cassava starch to adjust the concentration of starch milk, subsequently, the adjusted starch milk was poured into the reaction tank, and then anhydrous sodium sulfate was added. The pH value was adjusted with dilute alkali solution, and then protein powder was added. In this project, anhydrous sodium sulfate is used as swelling inhibitor to adjust pH value with dilute alkali, and propylene oxide and starch are subjected to bimolecular amphiphilic reaction under alkaline conditions to activate starch hydroxyl groups and improve etherification reaction, to further improve the degree of substitution; In the original hydroxypropyl starch process by directly increasing the cross-linking reaction, so as to develop hydroxypropyl distarch phosphate process.

Abstract:
The invention discloses a method of double-matrix super absorbent resin, which is characterized in that under cooling in an ice water bath, the acrylic acid of the polymerization inhibitor is neutralized with a sodium hydroxide solution, carboxymethyl starch and starch phosphate are mixed with deionized water and stirred, and acrylic acid and its sodium salt solution, potassium persulfate and N,N & prime;-methylenebisacrylamide solution are added, then, under the protection of nitrogen, the Graft polymerization of carboxymethyl starch and starch phosphate with acrylic acid and its sodium salt is carried out by stirring and heating in a water bath, and the temperature is maintained in a water bath within a certain range, then the nitrogen gas flow is stopped, the product is taken out, dried and crushed, and the double matrix super absorbent resin is obtained. The super absorbent resin prepared by the method can be used as a soil water retaining agent and an amendment, and has a broad application prospect in agriculture, forestry, horticulture and the like, and the super absorbent resin contains phosphorus nutrients, the soil fertility can be improved while the drought resistance of plants is enhanced.

overview | double starch phosphate is a chemical substance with certain toxicity. it will decompose pungent smoke when heated. it is white powder, with high gelatinization temperature and low wetting degree. the Chinese alias is phosphate double starch; distarch phosphate; starch phosphate; when the strength, adhesion and hardness of phosphate double starch are poor, it has great influence on the taste and performance of flour and other products. Therefore, it is of great significance to prepare the best phosphate double starch in the field of flour. |
application | phosphate double starch is a modified starch obtained by cross-linking reaction between starch and phosphorylation reagent. GB2760 in China stipulates that it can be used as a thickener in various food production according to appropriate amount, and cross-linking bonds are introduced into the molecular structure, thus inhibiting the water absorption and swelling degree of starch particles, it can enhance the aging performance of starch, gel strength and thermal stability of paste. Compared with the original starch, phosphate double starch is widely used in frozen food, canned food and pudding products. |
preparation | a preparation process of double starch phosphate ester, which includes the following steps: injecting process water into a feeding tank, putting raw starch into a feeding tank, adjusting the concentration of starch milk to 18 bami degree, and beating the adjusted starch slurry to a reaction tank; Adding anhydrous sodium sulfate with 0.5% starch quality, adjusting the pH to 10.0 with sodium hydroxide solution, and then adding phosphorus oxytrichloride with 0.15% starch amount, after the reaction for 40min, dilute hydrochloric acid solution is added to adjust the pH to 4.5, the reaction is stopped, and the crude product is obtained, and then enzymatically hydrolyzed. The content of α-amylase in the crude product is 300U/g, the time is 1h, the temperature is 81 ℃, and the pH is 6.5. Then it is washed in a disc centrifuge. After washing, the conductivity of starch milk is less than or equal to 3000 μs/cm, then the scraper is dehydrated, and then dried in an air dryer, the drying tail air temperature is 35 ℃-70 ℃, the moisture content of the dried finished product is less than 18%, then the finished product is screened to fineness ≥ 99.0%, then the finished product is packaged with a net content of 25kg, and then put into storage. |
