The main differences between edible gelatin and medicinal gelatin are their production requirements, application fields and quality control standards.
- Production requirements: Edible gelatin and medicinal gelatin are both made from animal skin, bone and other raw materials. However, the production requirements of medicinal gelatin are more stringent, with higher standards for the selection of raw materials and hygiene control in the production process. For example, leather waste cannot be used in the production of medicinal gelatin to avoid contamination by harmful substances such as chromium, because the leather may be tanned with chromium salts in the tanning process.
- Application fields: Edible gelatin is widely used in the food industry, such as jellies, candy, sausages, etc., as a thickener, stabilizer or emulsifier. Medicinal gelatin is mainly used in the manufacture of hollow capsules and tablet coating, and can also be used for medical purposes such as plasma substitute and coating of drugs.
- Quality control standards: The quality control standards of medicinal gelatin are usually more stringent than those of edible gelatin. Medicinal gelatin needs to meet specific requirements for physical properties, chemical properties and microbial limits. For example, the chromium content of medicinal gelatin needs to be controlled within a safe range to prevent harm to human body.
In summary, although edible gelatin and medicinal gelatin have similarities in raw materials and production processes, medicinal gelatin is more strict and professional in terms of production requirements, application fields and quality control to ensure its safety and effectiveness in medical and pharmaceutical production.
