Texturní vlastnosti drůbežího masa a výrobků
Radomská, Silvie
Texture is taken as a complex of properties that can be divided into mechanical, geometrical and surface. Among the mechanical properties include hardness, cohesiveness, adhesiveness, elasticity, viscosity and brittleness, chewiness and gumminess. The group of geometric properties include attributes relating to size and shape. Among the surface properties include juiciness. Textural properties of poultry meat and meat products are affected by factors such as species, breed, sex, age, method and level of nutrition, health, stress or post-mortem effects. They are also textural properties affected by the chemical composition and structure of meat. Evaluation of textural properties may be using sensory and instrumental methods. Sensory evaluation methods nowadays serves as a supplement to instrumental methods. Instrumental methods can be divided into basic, empirical and imitation. Empirical methods incorporate shearing test using a Warner-Bratzler and Meullenet-Owens razor blade, a compression test using a Kramer cell and penetration tests. Imitating methods are represented by texture profile analysis.
