Natural antioxidant VS Traditional antioxidant: substitution and new choice?
¡ó¡ó¡ó¡ó¡ó¡ó¡ó¡ó¡ó¡ó¡ó¡ó¡ó¡ó¡ó¡ó¡ó¡ó¡ó¡ó¡ó¡ó¡ó¡ó¡ó¡ó¡ó [Description]:Rosemary (Rosmarinus officinalis L)P.E.RosA4.5%(Water Soluble [Botanical Source]:Rosmarinus officinalis L,leaves [Common name]:Rosemary [Effective Content]:RosA.
1,Traditional Antioxidant,what is TBHQ? Amerol TBHQ is an antioxidant which offers excellent solubility in fats and o ils. Used alone or in combination with other Amerol antioxidants it adds stabilit y 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 so luble 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 r equired by the US Food and Drug Administration. However, the same chemical properties which make BHA and BHT excellent preser vatives may also be implicated in health effects. The oxidative characteristics and/or metabolites of BHA and BHT may contribut e to carcinogenicity or tumorigenicity; however the same reactions may combat oxi dative stress. There is evidence that certain persons may have difficulty metabolizing BHA a nd BHT, resulting in health and behavior changes. BHA and BHT may have antiviral and antimicrobial activities. Research is unde rway 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)]
Description:ROSEMARY EXTRACT - (ANTIOXIDANTS) Apperance: Light Brown to Brown standard fine powder extracts, Oil/Water solu ble. Functional Use in Foods: Antioxidant. Superiority: Super and Strong restrain and control ability for lipoid-oxid;
<1>.Highly Effective£º Highly Effective£º Rosemary Antioxidant effect 2 to 4 times as BHT or BHA as Antioxidant in different base oil, more effective than VC, and could be 1 to 2 ti mes. <2>Good Stability: stable in high temperature and environment, even could be in good condition at 240 ¡æ. <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 a s E. coli and S. aureus that are involved in food spoilage, and may actually perf orm 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 ant ioxidant properties may have activity against colon, breast, stomach, lung, and s kin cancer cells. <8>Reduce serum total cholesterol and fatty tissue : not only effectively dec reases serum cholesterol levels, but also reduces the cholesterol content in diff erent tissues such as liver, heart and fatty tissue
Application: show good effect when add before the period of oxidation , add r ate 200 to 1000ppm(0.02% ~0.1%) according to the concentration of fat content in base oiladd directly in base oil.

[Result of Comparative Analysis] Comparative Analysis shows that:
<1>.Rosemary Antioxidant is more functional both in tallow and plant oil(pean ut oil or soy bean oil) than other chemical antioxidant such as BHA,BHT,and also more funct-ional than famous antioxidant natural Tea polyhenols. <2>.And Rosemary Antioxidant could effective 2 to 4 times as same amount of B HA in peanut oil or other plant oil such as soy bean oil, and the ability of Rose mary Antioxidant in Tallow(such as lard) could be 1 to 2 times as Tea polyphenols and 2 to 4 times as BHA. <3>.Rosemary Antioxidant could be more effective when Temperature higher than 100¡æ,of course also best solubility and stability.
