【 摘 要 】

The purpose of the study is to determine the structural characteristics of the texture of chilled and frozen meat of chickens and turkeys. The object of the study were chicken and turkey breast and legs frozen and refrigerated. Research was carried out using two methods - the analysis of the profile of texture (TPA) and shear Warner-Bratzler (WB). The total chemical composition determined by methods: total protein - Kjeldahl, carbohydrates, fats and total ash down in the relevant known methods. Samples have similar protein containing identical anatomical sites, have some differences in the content of fat and minerals. The results show that the water content of the turkey breasts and legs lower than with the chicken at about equal protein content. According to analysis of variance (ANOVA), a statistical difference was observed between the shear forces of refrigerated and frozen chicken legs, but no significant differences in the results of the shear characteristics of the refrigerated and frozen chicken breast samples were detected. Parameters produced by Warner-Bratzler correlates well with the characteristics of strength, hardness and wiry, obtained by texture profile analysis. The results indicate that the test samples have different textural characteristics depending on the type of meat and the thermal state. Methods of Warner-Bratzler and ATP method in combination with others, may be used to determine in which the thermal state (chilled or frozen) were meat turkey and chicken.
