Gelatin CAS 9000-70-8

Molecular Formula: AlH3KO8S2 Molecular Weight: 261.229 CAS No.: 9000-70-8 Description Gelatin is a white or light yellow, translucent, micro-glossy sheet or powder that is degraded by collagen in connective tissues such as animal skin, bone, sarcolemma, and muscle. It is tasteless and odorless. Swelling in cold water. Soluble in hot water. Soluble in glycerin and acetic acid, insoluble in ethanol and ether. Application 1) Edible gelatin: Gelatin is an important ingredient and additive in the food industry. It is often used as a gelling agent, stabilizer, emulsifier, thickener and clarifier in the production of meat products, cakes, ice cream, beer, juice, etc. 2) Biofilm materials: The most researched gelatin-based film materials are chitosan-gelatin blended film, gelatin-silk fibroin blended film, polylactic acid-gelatin blended film and polyvinyl alcohol-gelatin blended film, etc. These blend materials greatly improve the physical and chemical properties of gelatin and make the gelatin-based polymer membrane materials more functional. 3) Medical fiber: use other composite materials and gelatin for blending and spinning to improve the mechanical properties of gelatin-based medical fiber materials. 4) Tissue repair and replacement: Gelatin-based composite materials used as tissue engineering scaffold materials and signal molecular carriers are one of the current research hotspots of biomaterials. The gelatin solution is cross-linked to form a hydrogel, in which water is a porogen, which forms a porous scaffold material after freeze-drying, and the porosity and pore size can be adjusted by changing the freezing parameters. Therefore, ideal gelatin-based tissue engineering materials can be designed according to different tissue repair requirements. 5) Industrial gelatin: used in the manufacture of fiber textiles, insulating materials, paper, holographic materials, etc. Specification Appearance Yellow to light yellow powder Jelly Strength, 6.67% 10 °C 110-130 Bloom g Viscosity, 6.67% 60 °C ≥2.2 mPa•s Transmission 450nm: ≥30% 620nm: ≥50% Transparency ≥300mm Moisture Content ≤12.0% Ashes Content ≤1.0% PH Value 3.8-7.6 Conductivity ≤1.0mS/cm Insoluble Particles ≤0.20% Particle Size 8-60mesh Reducing Substances ≤30mg/kg Peroxide ≤10mg/kg Heavy Metals(Pb) ≤50mg/kg Arsenic (As) ≤1.0mg/kg Chromium ≤2.0mg/kg Lead（Pb） ≤1.5mg/kg Iron（Fe） ≤30mg/kg Aerobic Plate Count ≤1000cfu/g Yeast and Mould ≤100cfu/g Coliform ≤3MPN/g E.Coli Negative in 10g Salmonella Negative in 25g Packing 25kg/kraft paper bag or as customer’s requirements.
