| Detailed Product Description： | Pre-gelatinized starch: Pre-gelatinized starch is a simple process, uses a wide range of modified starch, as long as the application into a paste with cold water transfer, eliminating the heat gelatinization of trouble. Widely used in medicine, food, cosmetics, animal feed, oil drilling, metal casting, textiles, paper and many other industries. Gelatinization of starch: starch grains at the appropriate temperature (the temperature required for a variety of different sources of starch, generally 60 ~ 80 ℃) in water swelling, splitting to form a uniform paste the role of the solution is called gelatinization. Gelatinization of starch granules is the essence of order and disorder (crystalline and amorphous) state of the hydrogen bonds between starch molecules break, dispersed in water a colloidal solution. Gelatinization process can be divided into three stages: (1) reversible phase water, water into the amorphous part of starch grains, a slight volume expansion, then cooling and drying, particles can be recovered, the same birefringence; ( 2) irreversible water phase, with the temperature, the moisture into the starch, microcrystalline gap, a lot of water is not reversible, fading and even the disappearance of birefringence, also known as crystal "dissolved", starch grains expansion to the original 50 to 100 times the volume of ; (3) the final dissolution of starch granules, starch molecules into the solution of all. Gelatinized starch, also known as α-starch. The freshly prepared dehydrated gelatinized starch slurry can be easily dispersed amorphous powder with cold water, that is "soluble α-amylase." Determination of starch gelatinization: an optical microscopy, electron microscopy, optical transmission method, viscosity measurement method, the determination of swelling and solubility, enzyme analysis, nuclear magnetic resonance, laser light scattering method. Determination of viscosity commonly used in industry, swelling and solubility determination of pre-gelatinized starch (α-amylase) Application materials level: mainly used for interior wall putty powder is 821, with a cold water solubility, CMC for powder coatings to replace. Feed Grade: eel feed use can show its features, it is non-toxic, easy to digest, nutritious, transparent, has been maintained in the eel after eating before the overall shape of particles. Casting Grade: sand cores for die casting. Adhesives, rubber and strong into the molten metal when complete combustion does not produce bubbles, products do not contain "trachoma" smooth surface. |
