Yellow Dextrin is a carbohydrare that is a water-solube polysaccharide formed by the hydrolysis of starch ,itself a carbohydrarte .We cleave or break the very long chain called starch via hydrolysis ,we get a bunch of shorter but still pretty long chains ,that is dextrins .Yellow dextrin ,which is also called canary dextrins ,it is easy mixed with water than original starch .DM-yellow tapioca dextrin is artificially produced from high quality tapioca starch using acid ,which can be used for food and industrial.

1. Determination of thermal viscosity

Weigh 150.0g of sample and place it in a 1000mL iron cup. Add 350mL of distilled water to make starch milk. Place the iron cup in a boiling water bath for heating. At the same time, use an electric mixer to stir the starch milk. The speed of the mixer is 300r · min-1. Keep the temperature at 90~95 ℃ for 30min. Pour the above starch emulsion into a 500mL beaker, cool it to 25 ℃, and test it with DV-S viscometer. Viscometer parameters: 3 # rotor, 30r · min-1 speed. The reading value is the thermal viscosity.

2.Determination of cold viscosity

Control the room temperature at 25 ℃, weigh 150.0g of sample and place it in a 1000mL iron cup, add 350mL of distilled water to make starch milk, and use an electric mixer to stir the starch milk. The speed of the mixer is 1300r · min-1, and the mixing time is 30min. Pour the above starch milk into a 500mL beaker, and use DV-S viscometer to test. Viscometer parameters: 3 # rotor, 30r · min-1 speed. The reading value is the cold viscosity.

Yellow dextrin has strong applicability and wide application

It is widely used in sewage treatment, textile industry, printing and dyeing industry, paint industry, construction industry, packaging industry, chemical industry, etc.
