100 g of berries were hydrated and milled with 1000 g hot water (80-100° C.). Paste was centrifuged 3 min at 3000 Rpm. Settling with 5-71 Bx and moisture less that 82% was extracted 3 times with 400 g ethyl acetate at a temperature of 60° C. The extracts were combined, filtered and evaporated under reduced pressure to apparent dryness to form an organic solvent-free homogenous oleoresin containing zeaxanthin dipalmitate for saponification. Zeaxanthin dipalmitate concentration in oleoresin 13-15%.
