Genipin with CAS number 6902 - 77 - 8 is a natural iridoid compound. It is obtained from the fruit of Gardenia jasminoides Ellis. This product is offered at the best price by our factory supply. The chemical formula of genipin is C₁₁H₁₄O₅, and its molecular weight is approximately 226.22 g/mol. The appearance of genipin is usually a white to light - yellow powder. It has a relatively high purity, and our factory ensures strict quality control to meet the high - standard requirements of customers.
Genipin is soluble in some polar solvents such as methanol, ethanol, and water to a certain extent. Its stability is affected by factors like temperature, light, and pH. It is recommended to store it in a cool, dry place away from light to maintain its quality over time.
1. **Food Industry**: Genipin can be used as a natural cross - linking agent and color - forming agent in the food industry. It can react with amino - containing compounds in food proteins to form blue - black complexes, which can be used for food coloring. For example, it can be used to color meat products, giving them a unique appearance and improving their marketability.
2. **Biomedical Field**: In tissue engineering, genipin is widely used as a cross - linking agent for biomaterials. It can cross - link natural polymers such as chitosan and gelatin to improve their mechanical properties and biocompatibility. This makes it suitable for the preparation of scaffolds for tissue repair and regeneration. Additionally, genipin has shown some potential in drug delivery systems, as it can be used to modify carriers to control the release of drugs.
3. **Cosmetics Industry**: Due to its antioxidant and anti - inflammatory properties, genipin can be incorporated into cosmetics. It can help protect the skin from oxidative damage and reduce skin inflammation, which is beneficial for skin health and anti - aging.
1. **Food Application**: When using genipin in food, first, accurately weigh the required amount of genipin according to the formula. Dissolve it in a small amount of appropriate solvent (such as ethanol or water) at a low temperature. Then, add the solution to the food material under stirring conditions. Make sure to control the reaction time and temperature to achieve the desired coloring effect. After the reaction is complete, the food can be further processed according to normal procedures.
2. **Biomedical Application**: In tissue engineering, when using genipin as a cross - linking agent for biomaterials, prepare a solution of genipin with a suitable concentration. Immerse the biomaterial in the genipin solution for a certain period of time, usually several hours to overnight, depending on the specific requirements of the application. Then, wash the cross - linked biomaterial thoroughly to remove the unreacted genipin. For drug delivery systems, genipin can be used in the synthesis or modification process following specific chemical reaction procedures.
3. **Cosmetics Application**: In cosmetics, genipin can be added to the formulation during the production process. It should be added under gentle stirring at a suitable temperature to ensure uniform dispersion. The concentration of genipin in cosmetics should be determined according to relevant regulations and product performance requirements.
**Food Coloring in Sausages**: A meat processing company wanted to develop a new type of sausage with a unique appearance. They added genipin to the sausage formulation. First, they dissolved 0.1% genipin (by weight of the sausage meat) in a small amount of ethanol. Then, they added the solution to the minced meat during the mixing process. After stuffing the sausage casings, they let the sausage sit at room temperature for 2 hours. The resulting sausage had a distinct blue - black color, which was very popular among consumers. The cross - linking effect of genipin also improved the texture of the sausage, making it more elastic.
**Tissue Engineering Scaffold for Bone Repair**: A research team was working on a bone tissue engineering project. They used chitosan as the base material for the scaffold. They prepared a 2% genipin solution in phosphate - buffered saline. The chitosan scaffolds were immersed in the genipin solution for 12 hours at 4°C. After cross - linking, the mechanical strength of the scaffolds increased significantly, and the biocompatibility was also improved. When seeded with bone - forming cells, the scaffolds supported cell adhesion, proliferation, and differentiation, showing great potential for bone repair.
