Special Issue Information

Dear Colleagues,

Food consumers are changing their attitudes towards nutrition and health by promoting an appreciation of food value and sustainable cost. Preferences towards eco-friendly manufacturing and products that contribute to human health and wellbeing are progressively modifying the food system chain. Supercritical Fluid Technology appears as an alternative to attain these goals, i.e., green processing that results in high-quality foodstuffs.

Supercritical carbon dioxide (SCCO2) is the most commonly used supercritical fluid, leading to innovative applications in food science and technology. Extraction, fractionation, chemical and enzymatic reaction, analytical and preparative separations, particle formation, encapsulation, preservation, etc. are most recognized operations in which supercritical technology set up eye-catching food applications.

The upcoming Special Issue aims to gather innovative applications and the most recent advances in the field of the Supercritical Fluid Technology applied to food system development, processes and products. Theoretical and applied research describing original experimental data, advances in process applications, products particularities and characteristics, singular case studies, etc., are welcome.

Main topics include, but are not limited to:

  • Extraction, fractionation and purification
  • Microbial inactivation
  • Biological activities of products
  • Micronization, impregnation and encapsulation
  • Chemical and enzymatic reactions
  • Analytical and preparative chromatography
  • Process simulation and optimization
  • Process scaling up
  • Economic and environmental impact assessment and marketing

Heather (Calluna vulgaris L.) and marigold (Calendula officinalis L.) are two rich sources of bioactive pentacyclic triterpenes. The supercritical carbon dioxide (SCCO2) extraction of these two plants was explored at a pressure range of 25–50 MPa, 50 °C, with or without fractionation, different extraction times (1.5–4.0 h) and using ethanol as a co-solvent (0 and 10% w/w). In order to determine potential synergisms, a combined extraction (heather + marigold 50:50) was also studied. In general, higher extraction yields were achieved when the co-solvent was added. Higher concentrations of total triterpenic acids were obtained in heather extracts, specially using ethanol. The co-solvent did not increase the terpene concentration in marigold extracts. For the combined extraction, an antagonist effect in the triterpene concentration was observed in absence of a co-solvent, whereas a synergistic effect was exhibited in its presence, especially for ursolic acid. In general, the extracts showed a certain anti-inflammatory effect, although a straight correlation with the analyzed triterpenic acids concentration was not exhibited. Moreover, the combined extraction exposed a similar anti-inflammatory activity in comparison with the individual plant extracts. Full article
