Screening of bioactive compounds in truffles and evaluation of pressurized liquid extractions (PLE) to obtain fractions with biological activities

Truffles, besides the appreciated aromatic compounds, contain other molecules with interesting bioactive properties. A screening of fungal sterols and β-glucans within different truffle species and locations was carried out. These compounds were extracted with pressurized liquids (PLE) generating enriched fractions. Extraction efficiency was studied with a full-factorial experimental design (Response surface methodology, RSM), using water and...
