บทคัดย่อ

Selection of wall materials is one of the critical steps for the successful encapsulation of polyunsaturated oils such as Sacha Inchi oil (SO) using spray drying. In this study, wall material composition was optimized from 10 experimental runs with different combinations of maltodextrin (MD), modified starch (MS), and whey protein concentrate (WPC) using a mixture design. The encapsulation efficiency (EE), process yield (PY), particle size, and hygroscopicity of SO microcapsules (SOMs) were first determined for individual runs with wall material concentrations being 0–15% w/w in the feed and the oil loading being 30% w/w of total solids. The results showed that WPC negatively affected the EE and PY. The R2 and desirability when predicting EE, PY, and hygroscopicity based on formulations using the mixture design model were relatively high 0.92, 0.77, and 0.92, respectively, with the optimal formulation predicted to be 9.25% w/w MD and 5.75% w/w MS in the feed. Microcapsules produced with the predicted optimal formulation had values close to the predictions (EE: 88.87% vs 87.79%; PY: 53.27% vs 60.51%; and hygroscopicity: 5.56% vs 5.23%). SOMs had a red blood cell shape without surface cracks or holes. Additionally, encapsulation extended the oxidative stability of SO up to 1 month at 25 °C. The strong non-acceptable volatile compounds initially present in SO, including hexanal, 2-heptanal, 2,4-heptadienal, and 2-octenal, become undetectable in the SOMs prepared with a ternary blend of MD, MS, and WPC. Therefore, formulations optimized in the present study may be applied to utilize SO in the form of spray-dried microcapsules. © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
