Summary

ANTHOCYANIN EXTRACTION FROM ELDERBERRY POMACE IS IMPROVED BY MECHANICAL DISINTEGRATION AND USE OF AQUEOUS HYDROGEN CHLORIDE, WITH PH BEING IMPORTANT IN DETERMINING EXTRACTANT EFFECTIVENESS. EXTRACTION AT LOW SOLVENT: POMACE RATIOS GIVES EXTRACTS OF HIGHER CONCENTRATION AND LOWER VOLUME, BUT WITH REDUCED EFFICIENCY. ENZYME PRETREATMENTS DO NOT IMPROVE EXTRACTABILITY FROM EXTENSIVELY CRUSHED POMACE, AND IF OF EXTENDED DURATION, CAN RESULT IN ANTHOCYANIN BREAKDOWN. VACUUM EVAPORATION GAVE LITTLE LOSS OF ANTHOCYANINS, AND COMBINED WITH FREEZE-DRYING, PRODUCED MATERIALS WITH HIGH ANTHOCYANIN RETENTION.
