2. Materials and methods
The set-up of the experiment will reflect that the goal of the study is
to establish whether the two types of equipment for color assessment
actually measure meat color in a similar manner. As stated in the intro-
duction, it has been concluded that the two instruments assess color
equally well when a color checker is concerned. The experiment is
therefore set up such that the possible differences in assessment will
be evident.
2.1. Samples
The experiment involved meat samples chosen such that they repre-sented the natural color variation in different meat types. Samples rang-
ing from dark red filet steak to lighter red pork loin and turkey breast
are included as well as different products of processed meat. In the latter
group of samples the meat samples have been processed by mincing,
boiling and frying. In total, 12 different meat products were investigat-
ed: Seven fresh and five processed products. Within each product cate-
gory there were five samples, giving a total of 60 samples. Table 1 gives
an overview of the samples considered in the study.
The non-processed meat types have been frozen and thawed in a re-
frigerator at 5 °C prior to the experiment. The five samples within each
type of product, originate from larger products. The larger products
were cut into slices of approximately 2 cm in height. Since the scope
