Importance of lecithin for encapsulation processes

Abstract

The crude soy and rice lecithin are used in studies of liposome formulation. They have been used as flavor encapsulators, flavor masking, antioxidants, and nutrient protective against degradations in the gastro intestinal tract. This study aimed to show the importance of rice and soy lecithin in its varied uses as liposomes in different areas. The paper indicates the importance of soy and rice lecithin, both crude and purified (phosphatidylcholine) ones, as feasible for the encapsulation of various materials, from medical and pharmaceutical to food ones.

Lecithin - Bifidobacterium probiotics interactions: a case study

“…Phosphatidyl choline is part of the molecular structure of the biological membranes. It is formed by two hydrocarbon chains, one saturated and one unsaturated, which constitute the hydrophobic part of the molecule and a glycerol, phosphate group, and choline that constitute the hydrophilic part (Adriana et al, 2014). Lecithin has also surface-active properties and it has been widely used as surfactant in the food and pharmaceutical industry (Adriana et al, 2014;Belitz et al, 2009).…”

Lecithin has also surface-active properties and it has been widely used as surfactant in the food and pharmaceutical industry (Adriana et al, 2014;Belitz et al, 2009). Since commercial lecithin's are complex mixtures of lipids, their HLB (Hydrophilic-Lipophilic Balance) values lie within a wide range (Belitz et al, 2009).…”

“…Since commercial lecithin's are complex mixtures of lipids, their HLB (Hydrophilic-Lipophilic Balance) values lie within a wide range (Belitz et al, 2009). Lecithin has the ability to protect various bioactive compounds (hydrophilic or hydrophobic) due to its ability to self-assemble into lipid vesicles (Adriana et al, 2014). It has been proved as stabilizer for vitamins (e.g.…”

Development of Biodegradable/Biocompatible Nanoliposome-Encapsulated Antimicrobial Essential Oils for Topical Creams and Gels

“…The primary structural component of the NLPs prepared in this study was food grade soy lecithin which is an inexpensive and safe source of phospholipid. Soy lecithin is also an excellent emulsifier, a nontoxic surfactant, and a stabilizer for vitamin E that was used in our application as one of the other structural components of the biodegradable biocompatible NLPs . In place of cholesterol, another typically used component in liposome preparations, we used phytosterol, which provides the same functionality as cholesterol in the preparation of NLPs but also other functional benefits related to the proposed topical end use. , Phytosterol is an agent used in skin care preparations supporting skin by improving moisture content and keeping the epidermis from drying while also stimulating the absorption of topical actives. − Encapsulating liposomes and their contents has been reportedly degraded by oxidation or hydrolysis .…”

Opportunities and Challenges for mRNA Delivery Nanoplatforms

“…Emulsion solvent evaporation method is also the main traditional technique to prepare mRNA delivery nanoplatforms, especially lipid polymer hybrid nanoparticles, mainly including single emulsification and double emulsification . Single emulsification refers to the monophasic nanoparticle structure of “oil-in-water” or “water-in-oil” formed by ultrasonic treatment between the aqueous phase and the organic phase containing lipids .…”
