Water-induced self-assembly of mixed gelator system (ceramide and lecithin) for edible oil structuring

Abstract

In the presence of a small amount of water, CER and LEC were self-assembled to form oleogels in sunflower oil. This can be used to produce hard-stock fat replacers as well as for incorporating water-soluble nutrients into oil-based products.

Modulating edible-oleogels physical and functional characteristics by controlling their microstructure

“…In this circumstance, water molecules interacted with OH groups in GS molecules as well as polar moieties in lecithin molecules. Using lecithin and ceramide as oleogelators, Guo et al 39 found that adding water entirely changed the crystal shape of the oleogel. In the presence of water in the oleogel system, they noticed that the large 3D crystals transformed into 2D crystals with smaller sizes and larger surface area, resulting in a harder structure.…”

The nutritional functions of dietary sphingomyelin and its applications in food

“…However, their application as food-grade oleogelators is limited due to their extremely crystalline fibril structures and high melting points. Guo et al added phosphatidylcholine to the mixed gel system of ceramides, and optimized the gel performance by changing the molar ratio of the components and the gel formation temperature ( 197 – 199 ). Generally, the effect of multi-component systems of oleogelators is often better than that of a single-component, and the gel performance can be optimized by changing the ratios of the components.…”

Preparation of Protein Oleogels: Effect on Structure and Functionality

“…Examples of LMWOGs that have been shown to form oleogels are monoglycerides [10][11][12][13][14][15][16][17][18], natural waxes [17,[19][20][21][22][23], enzymatically synthesized wax esters [24], ceramides [25], hydroxylated fatty acids [26,27], lecithin [28,29], and oligopeptides [30]. Additionally, combinations of LMWOGs have been studied, such as fatty acids and fatty alcohols [31,32], oleic acid and sodium oleate [33], sorbitan tri-stearate, tocopherol, phytosterol, β-citosterol or ceramide in combination with lecithin [34][35][36][37][38], γ-oryzanol and β-sitosterol [39][40][41][42][43], monoglycerides and phytosterols [44], beeswax and β-carotene [45], wax and monoglycerides [46], and combinations of fully hydrogenated oil, candedilla wax and monoglycerides [47].…”
