Abstract:

The aim of the study was to examine physicochemical characteristics of fish oil microcapsules produced at different temperatures and estimate the optimal ratio of BG, CS and spray drying temperature. Only the interaction between spray drying and β-d-glucan content played a significant role in influencing the encapsulation efficiency and spray drying itself (p ≤ 0.001 and p ≤ 0.05). Temperature played a significant role in increasing particle size as well, but the coefficient for this parameter was lower (0.179). The observed differences in particle size of microcapsules could be caused by the differences in glass transition temperature of the polymers (β-d-glucan and modified starch) used as wall material. It could be seen that the lowest TBARS content was observed when the β-d-glucan in the wall material was at relatively high level (85%) with moderate temperature applied (154 °C) - 0.56 mg of malonaldehyde/kg of powder. The highest amount of EPA was present in the sample with 50% share of β-d-glucan and spray dried in 150 °C (10.22 ± 0.24). After examination of all runs of the experiment, we have made optimization study to obtain the wall material composition and spray drying temperature values which will be most appropriate for fish oil encapsulation.
