Abstract:
Fish with higher nutrient qualities can be used to solve malnutrition problems in Africa. So the aim of this study was to evaluate the effect of local smoking on proximate composition and lipid oxidation of Chrysichthys nigrodigitatus collected in Cameroon. The proximate composition was assessed using standard methods while lipid quality assessment was based on the determination of biochemical indexes. A change on fatty acid composition was evaluated by gas chromatography while minerals composition was evaluated by spectrophotometer. On nutritional point of view, raw fish have high protein, li

Abstract:
Abstract Lipids are essential energy sources in nearly every animal’s diet. However, lipids used in feed formulations today are highly variable in both composition and susceptibility to oxidation – a major source of decreased lipid quality. Feeding oxidized lipids negatively influences animal health and performance, yet data on the oxidative status of commercially used lipids is limited. Herein, the oxidative stability results of lipid samples submitted to Kemin Customer Laboratory Services (CLS) for analysis since 2018 is summarized.

Human beings need macronutrients (lipids, carbohydrates, and proteins) in their diets. Among them, lipids are more susceptible to oxidative deteriorations. Oxidation and hydrolysis are two major lipid deterioration reactions that occurred during their processing and storage.

Lipid oxidation is a major cause of quality deterioration in food or cosmetic products. In these matrices, lipids are often present in a bulk or in emulsified forms.

In bulk oils, reverse micelles (association colloids) are present and are believed to play a crucial role on lipid oxidation. Conversely, in emulsions, surfactant micelles are present that also play a major role in lipid oxidation p

Abstract:
Food fortification is an efficient strategy to prevent vitamin A deficiency, a widely occurring health issue. However, vitamin A is rapidly degraded during food processing and storage, mainly due to oxidation. Therefore, there is a strong need for stabilising agents. In this study, we showed that wheat bran can be used as a natural, healthy and affordable stabilising agent slowing down vitamin A oxidation and lipid oxidation, which are closely related. The stabilising vitamin A-bran interaction was shown during an accelerated storage experiment (60°C, 70% relative humidity) using a model syste

Abstract:
In industrial fish filleting, around 30–70 % of the total weight of the fish end up as side streams (often called by- or co-products), such as the head, backbone, caudal fin, skin, and intestines. Currently, these fractions are dedicated to low value uses as fodder meals or mink feed, even if they contain significant amounts of protein, long chain (LC) n-3 polyunsaturated fatty acids (PUFA), and other nutrients such as vitamins and minerals. However, most fish processors mix their side streams, not least when it comes to small pelagic species like herring. This practice limits use of the side

Abstract:
Pickering emulsions have garnered great interest in food science lately. These systems are characterized by the use of colloidal particles as physical stabilizers, that strongly anchor at the oil-water interface, instead of conventional emulsifiers. Many biobased particles have recently been identified as useful for this application, which holds potential for revolutionizing the field of food emulsion formulation [1,2]. However, although the potential in terms of physical stabilization of oil-in-water (O/W) emulsions has been thoroughly explored in the past years, how such emulsions may resist

Abstract:
Elevated levels of low-density lipoprotein (LDL) are associated with increased risk of coronary heart disease (CHD). Although smaller LDL particles are more atherogenic, it is not clear how LDL particle size influences atherogenesis. Smaller particles may be more prone to macrophage uptake and plaque formation. Alternatively, increased rates of lipid oxidation may explain the atherogenic effects of smaller LDL. We have developed a mimic of LDL that allows independent examination of the effect of LDL size and oxidation. We have engineered LDL mimics using liposome-encapsulated gold nanoparticle

We have demonstrated that dinitrosyl iron complexes (DNICs) eliminate free radicals formed during the interaction of hemoproteins with tert-butyl hydroperoxide, as well as during the co-oxidation of lipids and glucose. Thus, DNICs act as antioxidants under conditions simulating different types of oxidative stress.

Abstract:
The oxidative chemical degradation produced by reactive species (free radicals, oxygen, etc.) is responsible for the deterioration of most of the formulated products. One of the main properties of an antioxidant lies in its capacity to limit the chemical propagation of oxidation by reducing free radicals. Another strategy to prevent oxidation is binding transition metals, since they are ubiquitous and deeply involved in the initiation and propagation of lipids oxidation. Naturally occurring phospholipids, polyphenols, proteins, or peptides that can bind metal ions could be more valued than syn

Abstract:
Food is an essential to our existence but under certain conditions it could become the origin to the accumulative health damages. Technological processes as heating, chopping, mincing, grounding, promote the lipid oxidation process in muscle tissues and meat foodstuffs. Lipid oxidation occurred rapidly in turkey muscle, intermediate in duck, and slowest in chicken during frozen storage. Depletion of tocopherol during frozen storage was more rapid in turkey and duck compared to chicken. These processes developed from lipid peroxides produce many cytotoxic compounds including malondialdehyde (MD

Several grape varieties and red wines were found to contain large concentration of phenolic compounds which work as antioxidant in-vitro and in-vivo. Wastes from wine production contain antioxidants in large amounts, between 2-6% on dry material basis. Red wines but also white wines were found to prevent lipid peroxidation of turkey muscle tissues stored at 5oC. The antioxidant reaction of flavonoids found in red wines against lipid peroxidation were found to depend on the structure of the molecule. Red wine flavonoids containing an orthodihydroxy structure around the B ring were found highly

Abstract:
General The final goal and overall objective of the current research has been to modify lipid hydroperoxidation in order to create desirable phenotypes in two important crops, potato and tomato, which normally are exposed to abiotic stress associated with such oxidation. The specific original objectives were: (i) the roles of lipoxygenase (LOX) and phospholipids hydroperoxide glutathione peroxidase (PHGPx) in regulating endogenous levels of lipid peroxidation in plant tissues; (ii) the effect of modified lipid peroxidation on fruit ripening, tuber quality, crop productivity and abiotic stress

Biological oxidations are almost exclusively metal ion-promoted reactions and in ths respect iron, being the most abundant, is the commonly involved. The effect of dietary iron levels on pork, turkey and chick muscle lipid peroxidation and various other related compounds were evaluated. Crossbred feeder pigs were fed to market weight on corn-soy rations containing either 62, 131 or 209 ppm iron. After slaughter, the muscles were dissected, cooked and stored at 4°C. Heavily fortifying swine rations with iron (>200 ppm) increase nn-heme iron (NHI), thiobarbituric acid reactive substances (TBA
