    Gender of dairy cattle did not influence all studied traits (P>0.05). Age at slaughter did not influence the most meat traits, except L* value (P<0.05). Meat from the oldest animals, 5 yr old, exhibited significantly lower L* value than the younger animals, 2, and 3 yr old (P<0.05). Marbling score significantly affected traits (P<0.05), except pH, a* and b* color values (P>0.05). The muscle obtained higher marbling scores had more dry matter and ether extracted (intramuscular fat content). Increased marbling score was related to decrease shear force. The lightness of muscle with the highest marbling score had the highest mean L* =52.8. There was strongly positive correlated between %DM and %EE (r= 0.91, P<0.01). The positive relationships between %EE, and L* and b* were found. Shear force was positively correlated with cooking loss (P<0.01), but it was negatively related to L* (P<0.01).

    Virgin coconut oil was used as green solvent for the extraction of total phenolics from I. herbstii (I. herbstii: coconut oil, 1:10 (w/w)). I. herbstii extract-containing coconut oil (ECC) had dark red in color. Acid value (AV), peroxide value (PV), thiobarbituric acid-reactive substances (TBARS), ρ-anisidine value and volatile compounds were taken as parameters for evaluation of oxidative stability of EEC sample. All parameters of EEC sample were lowered, in comparison with the control sample during storage for 7 weeks. ECC sample produced less TBARS value than the control (p<0.05). Abundance of volatile compounds in all samples correlated well with the TBARS value. Results revealed the use of coconut oil as green solvent for extraction of bioactive compounds and natural red pigment from I. herbstii, where I. herbstii as antioxidant to prevent lipid oxidation in vegetable oil.
