Effect of the emulsifier type on the physicochemical stability and in vitro digestibility of a lutein/zeaxanthin-enriched emulsion

Enhancing the stability of lutein emulsions with a water-soluble antioxidant and a oil-soluble antioxidant

“…Besides the oil and emulsifier, the preparation method may be much more critical to improve the lutein stability. Compared with the emulsions without any antioxidants [ 21 , [36] , [37] , [38] , 39 , 40 ], the lutein retention rates of this study under three temperature conditions are similar or better than them. The current study focused on the usage of combination of binary antioxidants.…”

Fabrication and characterization of nanoemulsions for encapsulation and delivery of vitexin: antioxidant activity, storage stability and in vitro digestibility

“…7(c). Different results in lipolysis of nanoemulsions may be obtained depending on the experimental conditions such as oil type and concentration, type and concentration of emulsifier, nature of encapsulated compounds and simulated small intestinal fluid compositions 10,12,45,60,62 …”

“…Different results in lipolysis of nanoemulsions may be obtained depending on the experimental conditions such as oil type and concentration, type and concentration of emulsifier, nature of encapsulated compounds and simulated small intestinal fluid compositions. 10,12,45,60,62 Typically, emulsified oil tends to show higher lipid hydrolysis during simulated intestinal digestion compared with bulk oil. This occurs because dispersed oil as droplets in emulsion systems produces a larger surface area for the binding of lipase and bile salts facilitates oil hydrolysis.…”

“…Oil‐in‐water nanoemulsions are suitable for less hydrophilic or lipid‐soluble compounds to control their stability, release and absorption 8,9 . Nanoemulsions can also prevent and reduce deterioration or retard the loss of bioactive compounds during processing, storage and in vitro digestion 7,10‐12 . Therefore, oil‐in‐water nanoemulsions containing vitexin in the oil phase is presumed to maintain functionality for longer storage times, with improved dispersion ability in aqueous medium systems.…”

“…The stability and delivery efficiency of encapsulated bioactive compounds in the nanoemulsion depend on many factors, including the method of preparation, type and concentration of emulsifier, type and concentration of oil phase and loading mechanism of the substance. [10][11][12][13][14] Using small-molecule emulsifiers to prepare nanoemulsions by a high-pressure homogenizer can result in an emulsion with smaller oil droplet size than using large molecule emulsifiers. This absorbs and creates a thin layer at the surface of the oil droplets faster and prevents the agglomeration of oil droplets.…”
