BAC2FOOD : Study and modelling of novel processing of foods to optimize nutritional functionality and bioaccessibility – The enginomic approach PI: Professor Dr. PETROS TAOUKIS 2nd Call for H.F.R.I. Research Projects for the Support of Faculty Members and Researchers (Project ID: 3591) P3: LCA Analysis: Environmental Impact of Extraction Technologies • Extraction methods compared: • MAE (Microwave-Assisted Extraction) • HPAE (High-Pressure Assisted Extraction) • PEF (Pulsed Electric Field) • CE (Conventional Extraction) • Impact per kg of extract: • MAE: Highest environmental impact due to low efficiency and high energy consumption. • HPAE: Lowest overall impact per kg extract, thanks to reduced energy use. • PEF: Best environmental footprint, combining low energy use and high extract efficiency. • CE: Relatively good impact; 2nd best after PEF. • Impact per g of phenolic content (GAE): • Switching from“per kg extract” to “per g GAE” changes rankings. • CE and HPAE: Lower environmental burden per g GAE due to high phenolic concentration in extracts. • PEF and MAE: Higher burden per g GAE because of lower phenolic yield per mass of extract. • Consistency: • Trends hold across all midpoint categories (climate change, water use, fossil depletion), supporting robust comparative conclusions.
