Effects of Phytosterol Butyrate Ester on the Characteristics of Soybean Phosphatidylcholine Liposomes

Abstract

IntroductionThere has been an increase in research investigating the role of liposomes in drug delivery and sustained release of bioactive compounds in the pharmaceutical, cosmetics, and food industries 1, 2 . Liposomes have been widely used to incorporate essential oils 3 , vitamins 4 , minerals 5 , enzymes 6 , antioxidants 7 , antibacterial agents 8 , etc. Liposomes are constituted amphiphilic lipid/phospholipid molecules and are well known as spherical vesicles with an aqueous core. These vesicles have several advantages, such as high bioavailability, biodegradability, and biocompatibility 9, 10 . The characteristics of liposomes depend on their composition, preparation method, and environmental conditions. Traditionally, cholesterol was added to the lipid membrane to improve the characteristics of the lipid

Effect of beta glucan coating on controlled release, bioaccessibility, and absorption of β-carotene from loaded liposomes

“…All these major bands associated with the soy phospholipid NLs were also reported in previous studies. 58,59 In the FTIR spectra of pure β-carotene (βC), a sharp peak observed at 966.5 cm −1 (represents the Trans C–H conjugated alkene group) is the characteristic peak used to identify βC. In βC-NLs, this characteristic peak can be observed at 1064.4 cm −1 , which confirms the presence of βC in the NLs structure (Fig.…”

Liposomes as Delivery System for Applications in Meat Products

“…The incorporation of cholesterol can influence lipid bilayer fluidity, reduce their permeability, and increase their in vitro and in vivo stability. Besides, there are still many components that can enhance the stability of liposomes, including propylene glycol and polyethylene glycol (PEG), phytosterols (PS)/phytosterol esters (PEs) [18], sea cucumber sulfated sterols [19], gum arabic (GA)/sodium alginate (SA) [20], guar gum (GG) [21], pectin [22], even chitosan [23] as coating materials.…”
