The effect of selected methods of heat treatment on the chemical composition, colour and texture parameters of longissimus dorsi muscle of wild boars

Abstract

The aim of this study was to analyse the impact of differentiation of cooking and baking temperatures on the chemical composition, colour, sensory evaluation, shear force and muscle texture parameters of the longissimus dorsal muscle of wild boars. It was shown that the increase in the final temperature during cooking and baking caused a decrease in the water content in the muscle, and as a result of the density of the tissue structure after the loss of this component, the fat content in the meat after heat treatment increases. Cooking at 80–90°C and baking at 150–175°C contributed to more favourable texture parameters such as hardness of cycles 1 and 2 and gumminess. In addition, it was found that the heat treatment affects the increase of the yellow colour and meat brightness, and at the same time the reduction of the a* parameter.
