Quality of Sika Deer Venison during Antler Growing Period
The quality of sika deer venison varies with the growth and development status of sika deer.In order to identify the nutritional composition and quality changes of sika deer venom during the antler growth period,the meat color(L*,a*,b*),pH24h,shear force,pressurized water loss rate,and moisture,fat and protein contents were determined at the early stage of sika deer antler growth,the middle stage of sika deer antler growth and the saw antler stage.The results showed that there were significant differences in moisture,fat and protein contents among foreleg,outer ridge,hind leg and neck meat of sika deer during antler growth period.In the same stage,the fat content in the outer ridge and neck meat was relatively high;the protein content was 23.15％,24.25％,23.73％,23.67％and 23.44％in the outer ridge at the early antler growth stage,middle antler growth stage and saw antler stage,respectively.During the whole antler growth period,the a*value of neck meat was the highest in the middle stage of antler growth,and there were no significant differences in L* value and b* value.At pH24h,neck meat was higher in the middle and saw antler growth stages of pilose antler.The water retention ability and tenderness of neck meat were better,and the water loss rate under pressure at different stages was the highest in the middle stage of pilose antler growth(26.70％).The results provide data support for the development of sika deer with both antler and meat.
