Antioxidants

Antioxidants are substances that can prevent or slow damage to cells caused by free radicals. Polyphenols are commonly found in food as natural antioxidants. Synthetic phenolic antioxidants are also added such as BHA (butylated hydroxyanisole), BHT (butylated hydroxytoluene), and TBHQ (tert-butylhydroquinone). Synthetic phenolic antioxidants are used in food systems for the prevention of lipid oxidation during processing and storage. This oxidation is responsible for the production of volatile compounds forming unpleasant flavors, so food and beverage companies need to test the antioxidants in their products and ensure consumer safety
How SIG can Help
SIG laboratory can perform analysis of the antioxidant and simultaneous testing for the analysis of the BHA, BHT and TBHQ antioxidants.
The types of antioxidants that can be tested in the SIG laboratory are:
- Tanine
- Caffeine
- Polyphenol
- Carotene
- Beta Carotene
- Ascorbyl Palmitate
- Butylated Hydroxyanisole (BHA)
- Butylated Hydroxytoluene (BHT)
- Tertbutyl hydroquinone (TBHQ)
Method of Analysis
