The Study of Changes in the Structural and Mechanical Properties of Turkey Fillet During Storage

Abstract

The method and equipment for the study of changes of structural-mechanical properties of turkey fillet at storage were offered. The improved express-method of the study allows determine the relaxation effort and time at axial deformation and the firmness limit of meat fibers using penetration. The selection of registering equipment and sensors for the study of structural-mechanical properties of turkey fillet was grounded. The methods of compensation of axial displacement of sensors at the study of penetration and relaxation were described. The principal scheme, appearance and example of work of setting were given. The changes of firmness and relaxation effort of cooled turkey fillet at different storage terms were characterized. It was established, that organoleptically perceptible changes of structural-mechanical properties of turkey fillet take place after 46 hours of storage. In first turn, relaxation is decelerated, the firmness limit is lowered that together with less firmness limit of fibers allows recommend it for formation of natural culinary goods of the given form, for example, rolls. The offered equipment and methodology of getting results of axial relaxation and penetration allows make conclusions about the essence of changes of rheological properties of turkey fillet and also recommend the studied samples for one or another type of culinary processing.

Improved method to determine structural-mechanical properties of turkey meat at axial deformation

“…The research was performed in the modules "rheology" and "Penetration" of the installation MIG 1.3 [13], Ukraine, made jointly by TOV "ITM", Kharkiv, Ukraine and KNTEU, Kyiv, Ukraine. A detailed description of methods and equipment is in [14].…”

“…When processing results of the penetration, we rejected those results of penetration, in which it was impossible to isolate a clear strength maximum [14]. In the process of mathematical-statistical processing, we discarded unreliable results (slips), which is why the number of credible results (n d ) for each sample was individual.…”
