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 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. This article provided an overview of major deteriorations of lipids and several pathways for their protection. The following conclusions were made: (i) oxidation and hydrolysis of lipids result in chemical, physical, nutritional and quality changes; (ⅱ) the oxidation rate varied by level of oxygen, composition of fatty aci

Specificity of targeting of the oxidative stress towards lipid and protein fractions in a model of estrogen-induced Syrian hamster nephrocarcinogenesis was evaluated. The amount of proteins modified by oxidative stress was significantly elevated as early as one month after the initial implantation of estradiol to the experimental versus the control group, while the stress did not affect lipids. Subcellular localization of the oxidative stress target was determined by the analysis of protein oxidation in subcellular fractions of kidney cells. The endoplasmic reticulum membranes were the fractio

The issue of lipid changes in muscle foods under the action of atmospheric oxygen has captured the attention of researchers for over a century. Lipid oxidative processes initiate during the slaughtering of animals and persist throughout subsequent technological processing and storage of the finished product. The oxidation of lipids in muscle foods is a phenomenon extensively deliberated in the scientific community, acknowledged as one of the pivotal factors affecting their quality, safety, and human health. This review delves into the nature of lipid oxidation in muscle foods, highlighting mec

Cholesterol (Ch) is one of the most important components of biological membranes, which has a significant impact on their biophysical properties. As a key component of lipid membranes, Ch along with other unsaturated lipids present in a biological membrane undergoes oxidation reaction during oxidative stress. Cholesterol oxidation products, cholesteryl esters and metabolites are also localise in lipid membranes, where they may modify membrane properties. In this work the impact of cholesterol, selected cholesteryl esters, cholesterol oxidation products and metabolites on lipid peroxidation ind

The diary industry uses various technologies to extend the shelf life of milk products. However, longer shelf life of foodstuffs frequently results in their lower nutritional levels. Milk fat contains more than 400 fatty acids, which are involved in the development of the human nervous system and other biochemical processes. Similar to other fats, milk fat is susceptible to oxidative damage during storage. This affects such basic components of milk fat as fatty acids and triacylglycerides. At present, milk is used for the production of functional foods for infants and children. The shelf life

ROS are highly reactive and cause in single cells: protein alteration, DNA damage, cellular senescence and apoptosis; while the effect of ROS in biological tissues leads to a harmful oxidation effect on all their biochemical components: lipids, proteins, carbohydrates, and nucleic acids.

Lipids are present in muscles as structural components of the muscle membranes, as storage droplets of triacylglycerol between muscle fibres and as adipose tissue (marbling fat). These lipids, or more precisely their fatty acids, contribute to a wide range of quality attributes. For fresh meat these are colour stability, drip loss and the development of oxidative rancidity. Meat colour and level of marbling are the two major factors relevant to the selection of meat by the consumer. Eating quality of meat is judged by texture and flavour.
