α-cyclodextrins have special

application in food industry,

especially as a natural soluble

dietary fiber

Plant cell cultures resulted valuable sources of bioactive

compounds (pharmaceuticals, nutraceuticals…)

ConclusionsLecce

Encapsulation in sodium alginate and α-cyclodextrin and storage

Extraction by SC-CO2 obtained enriched sources (wheat bran oil)

of bioactive compounds

Encapsulation in sodium alginate and α-cyclodextrin and storagein the dark at 4°C had synergistic effect in preventing the

degradation of bioactive compounds

Wheat bran encapsulated oil could be used as high-quality ready-

to-use stable ingredients in the preparation of novel functional

foods simultaneously enriched with:

• antioxidants• PUFA• fibers
