Applications
- Food and nutrition: controlled protein hydrolysis, meat tenderisation and digestive enzyme blends.
- Nutraceutical and supplement formulations standardised on GDU activity.
- Cosmetic and personal-care exfoliating and skin-soothing products.
Handling and Storage
Store in a cool, dry, well-ventilated place with the container tightly closed, away from heat and humidity. Bromelain is a protein and loses activity on prolonged exposure to heat or extreme pH, so keep it within the temperature and pH limits given in the safety data sheet. Use appropriate personal protective equipment to limit dust and avoid inhalation.
FAQ
What is bromelain used for? It is a proteolytic enzyme used in food processing, nutrition supplements, cosmetics and other applications that call for controlled protein hydrolysis.
What is the CAS number of bromelain? CAS 9001-00-7.
How is bromelain activity measured? Activity is normally stated in GDU/g (gelatin digesting units per gram); this grade is standardised at 2400 GDU/g minimum.
Where can I read more? See the bromelain technical article for properties, production and applications.
