Embodiment 1

[0032] Low degraded starch 100kg

[0033] Macrogol 4000 1g

[0034] Make 1 g of polyethylene glycol 4000 into 1 L of aqueous solution. The low-degradation starch is put into a high-speed mixer, and the polyethylene glycol 4000 aqueous solution is added in portions under stirring, and stirred for at least 3 hours to obtain the product.

Embodiment 2

[0036] Low degraded starch 100kg

[0037] Polyacrylic acid 10g

[0038] The low-degradation starch and polyacrylic acid are respectively prepared into solutions, wherein the mass concentration of the low-degradation starch solution is 10%, and the polyacrylic acid solution is 0.1%, and the two are mixed with a sprayer and dried.

Embodiment 3

[0040] Hydroxypropyl starch 100kg / h (feed speed)

[0041] Polyethylene glycol 4000 50g / h (feed rate)

[0042] step

[0043] The parameters of the extruder are: the length-to-diameter ratio of the screw is 15:1, the rotation speed is 200rpm, the temperatures of the inlet and outlet and each slider are respectively:

[0044] Feed inlet: room temperature,

[0045] Slider 1: 60°C

[0046] Slider 2: 90°C

[0047] Slider 3: 140°C

[0048] Slider 4: 150°C

[0049] Slider 5: 145°C

[0050] Slider 6: 130°C

[0051] Outlet: 80°C.

[0052] Put the hydroxypropyl starch into the hopper of the extruder, start the extruder, the material enters the barrel under the drive of the screw, pour pure water into the extruder on the second slider, and connect the third slider to polyethylene Alcohol 4000 feeder, the fifth slider connected to vacuum for exhaust. The material is extruded into long strips through a die, and cut into pellets.

Abstract

The invention discloses an instant water-soluble starch film-forming composition, which comprises water-soluble starch and water-soluble auxiliary materials. The inner packaging in contact with food or medicine has the advantages of fast dissolution and controllable concentration after dissolution.

Description

technical field [0001] The invention relates to an instant water-soluble starch film-forming composition, in particular to the field and application of starch derivatives. Background technique [0002] Starch is formed by the aggregation of glucose molecules. It is the most common storage form of carbohydrates in cells. It is hydrolyzed to disaccharide stage to maltose, and glucose is obtained after complete hydrolysis. [0003] There are two types of starches, amylose and amylopectin. The former is an unbranched helical structure; the latter is formed by connecting 24 to 30 glucose residues end-to-end with α-1,4-glycosidic bonds, and α-1,6-glycosidic bonds at the branched chains. Starch is a nutrient stored in plants, stored in seeds and tubers, and the content of starch in all kinds of plants is relatively high. [0004] Native starch is insoluble in cold water, gelatinizes in hot water, and forms a viscous liquid. This process is often time-consuming. After starch has...
