Rheological properties of fruit fillings to yoghourts
Języki publikacji
Abstrakty
Badano wpływ temperatury w zakresie 25 – 60 st. C na właściwości reologiczne wsadów owocowych do jogurtu. Model Sisco najlepiej opisywał krzywe lepkości badanych wsadów owocowych (R2 = 0,997). Współczynnik konsystencji obniżał się istotnie wraz ze wzrostem temperatury, natomiast wskaźnik płynięcia był niezależny od temperatury i wyniósł 0,3. Najwyższą wartość energii aktywacji (Ea) posiadał wsad o smaku porzeczek czarnych, wynoszącą 27,88 kJ/mol. Natomiast Ea dla wsadu o smaku brzoskwiń wyniosła 16,18 kJ/mol, a dla wsadu o smaku truskawek 14,82 kJ/mol.
The effect of temperature at range 25 – 60 st.C on the rheological properties of fruit fillings to yoghourts was investigated. The Sisco model fits the best (R2?=,0997) the shear rate and apparent viscosity data. The consistency index essentially decreased with increase in temperature, while the flow index was independent from temperature (average value 0,3). The highest activation energy of flow 27,88 kJ/mol had a black-currant filling, whereas Ea for peach and strawberry fillings was 16,18 and 14,82 kJ/mol, respectively.
