Oxidation in Low Moisture Foods as a Function of Surface Lipids and Fat Content.

Lipid oxidation is a major limitation to the shelf-life of low moisture foods and can lead to food waste. Little is known of whether the surface lipids in low moisture foods are more susceptible to oxidation since they are exposed to the environment. Therefore, the purpose of this research is to compare the rate of oxidation in surface and total lipids.

In vitro digestion of edible nanostructured lipid carriers: Impact of a Candelilla wax gelator on performance.

In this study, food-grade nanostructured lipid carriers (NLCs) were used as delivery systems to overcome some of the limitations of solid lipid nanoparticles (SLNs) and liquid lipid nanoparticles (LLNs). Organogel NLCs were prepared using an oil phase consisting of a hydrophobic gelator (Candelilla wax) dispersed in liquid corn oil. The oil phase undergoes a gel-to-sol transition when heated, which means that oil-in-water nanoemulsions can be used as templates to form the NLCs.

Impact of legume protein type and location on lipid oxidation in fish oil-in-water emulsions: Lentil, pea, and faba bean proteins.

Emulsion-based delivery systems are being developed to incorporate ω-3 fatty acids into functional foods and beverages. There is interest in formulating these delivery systems from more sustainable and label-friendly ingredients. The aim of this study was therefore to examine the impact of plant-protein emulsifiers on the oxidative stability of 1wt% fish oil-in-water emulsions.

Natural emulsifiers - Biosurfactants, phospholipids, biopolymers, and colloidal particles: Molecular and physicochemical basis of functional performance.

There is increasing consumer pressure for commercial products that are more natural, sustainable, and environmentally friendly, including foods, cosmetics, detergents, and personal care products. Industry has responded by trying to identify natural alternatives to synthetic functional ingredients within these products. The focus of this review article is on the replacement of synthetic surfactants with natural emulsifiers, such as amphiphilic proteins, polysaccharides, biosurfactants, phospholipids, and bioparticles.

Lutein-enriched emulsion-based delivery systems: Influence of pH and temperature on physical and chemical stability.

Lutein may be utilized in foods as a natural pigment or nutraceutical ingredient to improve eye health. Nevertheless, its use is limited by its poor water-solubility and chemical instability. We evaluated the effect of storage temperature and pH on the physical and chemical stability of lutein-enriched emulsions prepared using caseinate.
