Optimization of the bioactive compounds content in raspberry during freeze-drying using response surface method
The production of high-quality freeze-dried raspberry was studied by response surface method. Two independent variables, temperature (X1) and time (X2) were determined as the most important factors affecting the final product quality estimated by the responses: total phenol (Y1), total anth...

| description | The production of high-quality freeze-dried raspberry was studied by response
surface method. Two independent variables, temperature (X1) and time (X2)
were determined as the most important factors affecting the final product
quality estimated by the responses: total phenol (Y1), total anthocyanin
(Y2), vitamin C (Y3) and total bioactive compounds (Y4) content. A two-factor
central composite design was used for freeze-drying experiments. The second
order polynomial models obtained were found to be significant (p<0.05) for
all responses. The statistical analysis of experimental data indicated that
only quadratic time variable (X22) had significant (p<0.05) effect on all
responses. The optimal conditions for all responses combined were found to
be: -31 ºC and 35 h. The experimental values of all responses obtained under
optimal conditions were in good agreement with predicted values which enables
the use of the proposed mathematical models for optimization of investigated
process. [Projekat Ministarstav nauke Republike Srbije, br. TR31044] |
