It had a higher nutritional value (higher fibre content and protein retention] (p 〈 0.05) and better cooking characteristics (higher cooking yield and moisture retention) (p 〈 0.05) than the control. The colour (a*, b*) increased; lightness and whiteness index decrease (p 〈 0.05). Hardness increase (p 〈 0.05) occurred because of CSF addition. Differential scanning calorimetry showed that fibre fortification did not interfere with the thermal transitions of the restructured meat. No significant differences were detected with the preference test scores of 4% or 8% CSF compared with the control. Restructured (4%-8% CSF) had a higher content of fibre and fat, which could be linoleic and linolenic acid, and an increase in the content of protein compared with those of commercial products, among had 1.62 and 2.25 mg AGE/g. Therefore, the restructured properties of common carp were governed by CSF addition.展开更多

Technological schemes and parameters are offered to obtain restructured carbamide. Possible versions of degradation of different structure prolonged action fertilizers are considered. It was shown that the most favorable conditions for degradation of polymer molecules are created when molar ratio of the initial carbamide and aldehyde is within 1:1-1.3, correspondingly. At such terms the linear structure molecules with rare cross-links are formed. Such structure is more accessible for penetration of ureasive ferments into polymer molecules.展开更多
