The stability of fresh emulsions was analyzed using the LUMiSizer dispersion analyzer (LUMiSizer-651 12 channelsBerlinGermany) at 4 °C25 °C 8 more and 40 °C.LS2108Lutein XanthanPropylene glycol alginateO/W emulsionLutein is a hydrophobic carotenoid with diverse bioactivities. For encapsulating the molecule in a novel methodwe prepared two emulsions from xanthan and propylene glycol alginate at the ratios of 3:7 and 4:6. The instability index and particle size of the emulsions were determined using a stability analyzer and laser particle size analyzer. The influence of crystallization on the emulsions was observed under a polarizing microscope. The effects of centrifugal force and storage on the lutein emulsions were analyzed by measuring the changes in absorbance. More details Edition152 Internal reference2108 Open publication →
