β-carotene and resveratrol loaded glycerol monostearate-based oleogels: Physico...

Oleogels are semi-solid systems that can function both as replacers of trans and saturated fats and/or as carriers of lipophilic bioactive compounds. However, bioactive compounds can affect the structure of the oleogel matrix and this effect depends on the properties of such compounds. Therefore, the aim of this study was to develop oleogels loaded with -carotene (BC) or resveratrol (R), with low concentrations...

Encapsulation of Active Pharmaceutical Ingredients in Lipid Micro/Nanoparticles...

Nanoencapsulation via spray cooling (also known as spray chilling and spray congealing) has been used with the aim to improve the functionality, solubility, and protection of drugs; as well as to reduce hygroscopicity; to modify taste and odor to enable oral administration; and many times to achieve a controlled release profile. It is a relatively simple technology, it does not require the use of low-cost solve...

Self-organizing structures of phosphatidylcholine in nonaqueous solvents: tailo...

In this paper, we investigated the role played by solvent type and additives (water [W] and citric acid [CA]) on the self-assembly of phosphatidylcholine (PtdCho) into gels. Soybean lecithin (L) served as the PtdCho source used in this study. Lecithin was combined with different oils: hexadecane (HEX), sunflower oil, and medium-chain triacylglycerol to explore its ability to form organogels. Among the solvents,...

Perspective on oleogelator mixtures, structure design and behaviour towards dig...

The concepts of either multi-component supramolecular gels or structures derived from oleogels have not yet been fully investigated to their respective potentials. The study of hybrid structures might cover technological points such as (i) how to vehiculate hydrosoluble and/or liposoluble bioactive components simultaneously? (ii) How could the framework of an oleogel contribute to a specific structure design st...

Tuning phytosterols-based oleogels properties by soybean lecithin addition in d...

Lecithin and phytosterols-based mixtures as hybrid structuring agents in differ...

In this study the effect of lecithin (L) addition and solvent quality in a well-established oleogel system formed by -sitosterol and -oryzanol (BG) was investigated. Medium chain triglycerides (MCT) and sunflower oil (SFO) were used as triglycerides and hexadecane (HEX) as a model of linear hydrocarbon. Lecithin was proposed due to its natural and versatile properties, showing different functionalities such as ...

Synergistic interactions between lecithin and fruit wax in oleogel formation

In this study, the effect of lecithin (LEC) on the crystallization and gelation of fruit wax (FW) with sunflower oil was researched. A synergistic effect on the gel strength was observed at FW : LEC ratios of 75 : 25 and 50 : 50, compared to the corresponding single component formulations (100 : 0 and 0 : 100). Even below the critical gelling concentration (Cg) of FW, the addition of lecithin enabled gel format...
