The proteolytic activity of the
enzyme in papaya peel was about 10 times lower than that in
the latex. Taking into account the activity of the enzyme, spice
batches were mixed with 30% and 45% papaya peels, in order to
formulate meat tenderizers. According to the sensory evaluation
of the cooked samples, the meat marinated with 30% of green
papaya peel, for 2 h at room temperature had the highest level
of acceptance for its soft texture and good flavor. In conclusion,
green papaya peel, dried, ground, and mixed with various spices
showed a great potential for use as a low-cost meat tenderizer.
Furthermore, the process described here allows the conversion of
papaya peels with a negative value to an essential value added
ingredient.
