Nano-lipid carriers stabilized by hydrophobically modified starch or sucrose stearate for the delivery of lutein as a nutraceutical beverage model

[Display omitted] In this study, nanoemulsions were formulated as nano-lipid carriers (NLCs) for lutein, a bioactive compound. Two different beverage grade emulsifiers, i.e. octenyl modified starch (OMS) and sucrose monostearate (SMS), were compared to evaluate their effect on different physicochemical characteristics of the fabricated nanocarriers. The results suggested that pre-heating of SMS had no significant effect on the droplet size and physical stability of the NLCs, including their creaming rate and rheological behavior. On the other hand, the nanoemulsions containing 5% SMS showed a shear thinning behavior. Although, SMS was able to create smaller lutein-loaded NLCs as compared to OMS, the accelerated stability analysis revealed that OMS stabilized carriers had considerably (p
