Its called "diffraction grating"!.
The muscle fiber structure of the meat, when combined
with water droplets, creates a reflection of
light off the water!.The fibrous structure of the meat causes separation of
colors much like happens with a prism!.
In the meat industry, it is known that the effect is enhanced when
phosphates are used to increase the amount of water held in the meat!. A
dry meat surface scatters rather than diffracts or reflects light!.
