Sodium caseinate (SC)-stabilized 40% oil-in-water nanoemulsions (NEs) could be transformed into elastic gels below a critical droplet size due to increase in ϕeff by a thicker steric barrier of SC, while whey protein (WPI)-stabilized NEs remained liquid due to thinner steric barrier of WPI.

Water-in-oil (W/O) emulsions are dispersed systems which are often used in the pharmaceutical, cosmetic and food industries as products, or as carriers of active substances. It is well known that they are very unstable, so that selection of the emulsifier and properties of the oil and water phase are main factors affecting their stability. The aim of this paper was to examine the possibility of application of a lipophilic, polymeric emulsifier, PEG 30-dipolyhydroxystearate (CithrolTM DPHS), for stabilization of W/O emulsions. Behaviour of the emulsifier at W/O interfaces was determined by means of tensiometry. A series of emulsions were prepared with 20% (w/w) of water and different types of oil. Droplet size, droplet size distribution, viscosity, and sedimentation stability during 30 days of storage at room temperature of the emulsions prepared with paraffin oil, olive oil, grape seed oil, and medium-chain triglycerides, stabilized with 1% CithrolTM DPHS, were determined. All investigated emulsions were stable for 30 days, except the one prepared with paraffin oil. The results of this study confirmed that PEG 30-dipolyhydroxylstearate is a good emulsifier and stabilizer of W/O emulsions which contain different types of oil.

Sea buckthorn oil-in-water emulsions were prepared through high pressure homogenization, and the effects of droplet size, oil content, and emulsifier type on emulsion properties and the overall antioxidant activity of the emulsions were evaluated. Emulsions with different droplet size were obtained by varying homogenization pressure, and higher oil content resulted in bigger droplet size of the emulsions. Among three tested emulsifiers, sodium caseinate and sugar ester were able to form emulsions with much smaller particle size than soy protein isolate. The emulsions with bigger droplets tended to cream in an accelerated centrifugation test. The antioxidant property of the emulsions was expressed as their DPPH radical scavenging activity. The emulsions processed at lower pressure or contained higher oil content had higher DPPH radical scavenging activity. The soy protein isolate-stabilized emulsion presented higher antioxidant activity than sodium caseinate- and sugar ester-stabilized ones. Upon storage, the antioxidant activity of the emulsions was decreased due to the changes in emulsion stability and the degradation of antioxidants. The knowledge obtained in this study would be useful in developing healthy food containing sea buckthorn oil.

ABSTRACTAlthough fruits and vegetables, sources of carotenoids, are widely available in Brazil, hypovitaminosis A constitutes a serious public health problem. There is lack of information available to the population about the dietary sources of carotenoids and factors affecting their bioavailability.The carotenoids also known as bioactive compounds have been associated with the reduction of the risk for degenerative diseases, such as cancer (modulators of immunological responses), cardiovascular diseases, macular degeneration and cataract.In Brazil the utilization of buriti fruit is not widespread; it is consumed only by the local population of some parts of the North and Central regions. Among those foods, out the foods of buritizeiro, the buriti has the highest content of β-carotene among the numerous foods already analyzed, as well as a source of oleic fatty acid, similar to olive oil.The buriti fruit provides the needs of DRI.s (Dietary Reference Intake) of vitamin A for adult, being a good source of nutrition, knowing the variety of foods that composes a balanced diet. Also, the buriti fruit is a natural source of β-carotene (provitamin A). Also, it has antioxidant power by having carotenoids, polyphenols, vitamin C compared to other vegetables, can be considered a functional food.
