Present study clearly indicate that, both oil soluble and water dispersible
carnosic acid (CA) extracted from dried rosemary leaves
exhibited similar effects in inhibiting lipid oxidation in ground raw
and cooked buffalo meat patties and chicken patties. Total phenolic
content of these extracts had no effect on their antioxidant activity,
however CA dosage showed that lower dosage (22.5 ppm) was efficient
in limiting lipid oxidation equivalent to that of BHT, but failed
to protect the raw buffalo meat color during prolonged refrigerated
storage. On the other hand, CA higher dosage (130 ppm) was highly
effective in controlling lipid oxidation and metmyoglobin oxidation,
thereby stabilizing ground buffalo meat and chicken lipids and raw
buffalo meat color. However, higher dosage of standard oleoresin
(OxiKan-S10) exhibited slightly “Spicy” flavor which shows the significance
of refining of antioxidants in the meat applications
