Abstract
In this research, the impact of short-path molecular distillation (SPMD), as a green and solventless method, in the deacidification of cold-pressed camelina oil (CPCO) was investigated. Physical refining of crude vegetable oils with high free fatty acids (FFA) content leads to healthier oils, preventing excessive oil loss and minimizing waste production. Using central composite design approach-based response surface methodology (RSM-CCD) analysis, optimized SPMD process parameters were determined and verified. The investigated factors were evaporation temperature (ET: 160–200 °C), feed flow rate (Q: 0.50–3.00 mL/min), and feed temperature (FT: 80–120 °C). Deacidification efficiency (DE) and distillate-to-feed mass ratio (D/F) were selected as the separation performance responses. In addition, to monitor the qualitative effect of the SPMD, peroxide value (PV) and total polar compounds (PC) were designated as the complementary responses. The optimized values for ET, Q, and FT could be considered to be 200 °C, 0.50 mL/min, and 100 °C, respectively. At the optimum operating conditions, DE, D/F, PV, and PC were determined as 63.27 %, 5.78 %, 24.5 meq/kg, and 11.4 wt%, respectively. The SPMD were compared with conventional fractional distillation (FD), steam stripping distillation (SSD), and alkali neutralization (AN). It was validated that SPMD could efficiently and sustainably deacidify the CPCO. Additionally, the effect of two successive SPMD treatments at the optimum conditions was also examined. By double deacidification, the DE, D/F, PV, and PC values were 74.34 %, 6.88 %, 27.6 meq/kg, and 16.0 wt%, respectively.
期刊介绍:
Official Journal of the European Federation of Chemical Engineering:
Part C
FBP aims to be the principal international journal for publication of high quality, original papers in the branches of engineering and science dedicated to the safe processing of biological products. It is the only journal to exploit the synergy between biotechnology, bioprocessing and food engineering.
Papers showing how research results can be used in engineering design, and accounts of experimental or theoretical research work bringing new perspectives to established principles, highlighting unsolved problems or indicating directions for future research, are particularly welcome. Contributions that deal with new developments in equipment or processes and that can be given quantitative expression are encouraged. The journal is especially interested in papers that extend the boundaries of food and bioproducts processing.
The journal has a strong emphasis on the interface between engineering and food or bioproducts. Papers that are not likely to be published are those:
• Primarily concerned with food formulation
• That use experimental design techniques to obtain response surfaces but gain little insight from them
• That are empirical and ignore established mechanistic models, e.g., empirical drying curves
• That are primarily concerned about sensory evaluation and colour
• Concern the extraction, encapsulation and/or antioxidant activity of a specific biological material without providing insight that could be applied to a similar but different material,
• Containing only chemical analyses of biological materials.
