Natural antioxidant VS Traditional antioxidant:substitution and new choice.
1.Traditional Antioxidant,what is TBHQ?
Amerol TBHQ is an antioxidant which offers excellent solubility in fats and oils. Used alone or in combination with other Amerol antioxidants it adds stability to fats, oils, cereals and packaging materials.
TBHQ:tert-Butylhydroquinone; Mono-tert-butylhydroquinone
Chemical:C10H14O2 Formula wt 166.22 INS: 319 CAS:1948-33-0
Description:A white, crystalline solid having a characteristic odor. It is soluble in alcohol and in ether, but is practically insoluble in water.
Functional Use in Foods: Antioxidant.
2,why substitution?
Not safe?
Both BHA and BHT have undergone the additive application and review process required by the US Food and Drug Administration.
However, the same chemical properties which make BHA and BHT excellent preservatives may also be implicated in health effects.
The oxidative characteristics and/or metabolites of BHA and BHT may contribute to carcinogenicity or tumorigenicity; however the same reactions may combat oxidative stress.
There is evidence that certain persons may have difficulty metabolizing BHA and BHT, resulting in health and behavior changes.
BHA and BHT may have antiviral and antimicrobial activities. Research is underway concerning the use of BHT in the treatment of herpes simplex and AIDS.
3,And suggestive idea from green opinion:
Substitution of oil-antioxidant TBHQ(C10H14O2):natural rosemary antioxidant[ROSEMARY EXTRACT(ANTIOXIDANTS)]

2.Good Stability: stable in high temperature and environment, even could be in good condition at 240 deg C.
3.Easy Carry:Powder state and easy for packing and shipment.
4.Safe and no harm:no any harm and safe for final application.
5.Food Preservation:rosemary slows the growth of a number of bacteria such as E. coli and S. aureus that are involved in food spoilage, and may actually perform better than some commercially used food preservatives.
6.Alopecia:As stated above, one traditional use of rosemary has been to try to stimulate hair growth.
7.Anti-Cancer:Both laboratory and animal studies suggest that rosemary's antioxidant properties may have activity against colon, breast, stomach, lung, and skin cancer cells.
8.Reduce serum total cholesterol and fatty tissue : not only effectively decreases serum cholesterol levels, but also reduces the cholesterol content in different tissues such as liver, heart and fatty tissue
Application: show good effect when add before the period of oxidation , add rate 200 to 1000ppm(0.02% ~0.1%) according to the concentration of fat content in base oiladd directly in base oil.
