EFFECT OF TOTAL LIPIDS, TRIACYLGLYCEROLS AND PHOSPHOLIPIDS ON MALONALDEHYDE CONTENT IN DIFFERENT TYPES OF CHICKEN MUSCLES AND THE CORRESPONDING SKIN

Total lipid extracted from chicken breast, thigh, drumstick and wing muscles and the corresponding skin was analyzed for triacylglycerols and phospholipids as well as their fatty acid composition and also for malonaldehyde and lipid oxidation fluorescent products (LOFP) content.
Muscles consist of only 1.2–3.2% lipid, but lipid concentration in the skin ranges from 22.2–31.7%. The percentage of phospholipid in muscle lipid was 20 times more than that of the skin. The fatty acids of triacylglycerols from muscles and skin contained less than 2% of polyunsaturated fatty acids (PUFA). Fatty acids from phospholipid of the meat contained over 15% arachidonic acid and substantial amounts of PUFA with 22 carbon atoms. Skin phospholipid had 10.6–13.2% of all PUFA.
Differences in the lipid composition of muscles and skin resulted in a concentration of malonaldehyde in muscle lipids of 30–50 mg/g, a value more than 15 times greater than in lipids of the skin. However, the TBA number of the skin was the same or a little bit lower as compared to muscles. The relative levels of LOFP in the organic phase of Folch-extracted muscle and skin tissues paralleled the trend found for malonaldehyde concentrations.
It was concluded that the simultaneous determination of total lipid content and malonaldehyde concentration in lipid extracted from various chicken muscles and corresponding skin was the most informative method for evaluation of precursors of lipid oxidation in fresh tissue.     

VARIATION IN STIMULI ASSOCIATED WITH ORAL EVALUATION OF THE VISCOSITIES OF GLUCOSE SOLUTIONS

Abstract. Previous observations suggesting that different stimuli are associated with oral evaluation of the viscosity of fluid and of viscous foods have been confirmed. The change in stimuli begins at a viscosity of about 70 cp. In the initial study sensory evaluation of viscosity was by paired comparisons, while in this study distance measures and ratio scaling were used. The agreement between the data indicates that the observations are independent of the evaluation procedure employed.     

Investigation of the System CaO-MgO-V2O5: I, Phase Equilibria

The ternary subsolidus phase equilibria were determined for the system CaO-MgO-V₂O₅. Limits of crystalline solubility were determined along the meta- and orthovanadate joins. The metavanadate join was characterized as two large solution regions with the end-members as host structures separated by a small two-phase region. The orthovanadate join was characterized as a small solution region in the center with the defect garnet structure. Eighteen compatibility triangles were found to make up the proposed subsolidus equilibrium diagram.
