Lycopene is very susceptible to degradation once released from the protective chromoplast *** this study,oil-in-water(O/W)nanoemulsions coupled with spray drying technology were applied for the encapsulation and stabilization of lycopene extracted from tomato *** extract was obtained by ultrasound-assisted *** were prepared by a high-speed rotor stator using isopropyl myristate as the oil phase and Pluronic F-127 as the emulsifier for the aqueous external *** effect of emulsification process parameters was *** drying of the produced emulsions was attempted to obtain a stabilized dry powder after the addition of a coating *** effect of different coating agents(maltodextrin,inulin,gum arabic,pectin,whey and polyvinylpyrrolidone),drying temperature(120-170℃),and feed flow rate(3-9 ml·min^(-1))on the obtained particles was *** revealed that the emulsion formulation of 20/80(O/W)with 1.5%(mass fraction)of Pluronic F-127 as stabilizer in the aqueous phase resulted in a stable nanoemulsion with droplet sizes in the range of 259-276 nm with a unimodal and sharp size *** extract in the nanoemulsion was well protected at room temperature with a degradation rate of lycopene of about 50%during a month of storage *** most stable emulsions were then processed by spray drying to obtain a dry *** drying was particularly successful when using maltodextrin as a coating agent,obtaining dried spherical particles with mean diameters of(4.87±0.17)μm with a smooth *** possibility of dissolving the spray dried powder in order to *** original emulsion was also successfully verified.
