on average consumers will consider the meat colour acceptable. However a and L values must be much higher (14.5 and 44, respectively) to have 95% confidence that a randomly
selected consumer will consider a sample acceptable. For aged meat, when the wavelength ratio (630/
580 nm) and the a values are equal to or greater than 3.3 and 14.8, respectively, on average consumers
will consider the meat acceptable. These thresholds need to be increased to 6.8 for ratio (630/580 nm)
and 21.7 for a to be 95% confident that a randomly selected consumer will consider a sample acceptable.
