Abstract
Two experiments were performed to study the use
of papaya leaves as a meat tenderizer.The first experiment was to evaluate the
effect of papaya dry leaves added to hens’ diet before slaughter. Spent hens
(n=48) were used, half of them were fed a concentrate ration containing10% dried
papaya leaves powder (DPLP) while others received layer ration (Control), for 10
days. The second experiment involved a comparison between papaya leaves juice
(PLJ), fresh papaya leaves (FPL) and vinegar solution (VS) as marinades applied
to meat for one or two hours before cooking. Spent layer hens (n=42) were used
for tenderness evaluation method. After slaughtering and preparing the chickens
two methods of cooking were used (oven and moist cooking). The cooked parts
(breast, thigh and drumstick) were subjected to a panel test evaluation
according to a designed questionnaire. Addition of dried papaya leaves powder to
spent layer hens ration significantly (P≤0.05) increased the level of meat
tenderness. Moist cooking had significantly (P≤0.05) improved meat tenderization
compared to oven cooking. Meat treated with fresh papaya leaves had
significantly (P≤0.05) improved tenderness. It was concluded that wrapping the
tough meat of spent layer hens with fresh papaya leaves for one hour and moist
cooking improve tenderness of meat.
