Surface Reflectance Related with Color Characteristics for Pig x Wild Boar Meat
M. Irie, M. Nishimori
Abstract
Color characteristics of pig 횞 wild boar meat were determined with a fiber-optic spectrophotometer. The spectrophotometric characteristic of reduced-myoglobin observed after cutting immediately changed to the spectrophotometric characteristic of oxymyoglobin after 15 minutes of cutting. The spectrophotometry at 400 to 700 nm after 30, 45, 60, 90 and 120 minutes of cutting changed slightly. Compared with M. longissimus thoracis, M. rhomboideus had higher reflectance around 400 nm and from 650 to 1,100 nm and M. spinalis was lower in the visible light region after 60 minutes of cutting. The pig 횞 wild boar meat was similar in reflectance shape with pork but was lower in intensity. The differences depended on the anatomical location. The M. rhomboideus from pig 횞 wild boar had greatly lower reflectance than that from pig, the M. longissimus thoracis reflectance was lower, but M. spinalis reflectance hardly differed. These results showed that pig 횞 wild boar meat had no special characteristic of blooming but had distinguishing characteristic of meat color among anatomical locations.
