Prevention of Oxidative Stress and Diseases by Antioxidant Supplementation.

Excessive and uncontrolled oxidative stress can damage biomacromolecules, such as lipids, proteins, carbohydrates, and DNA, by free radical and oxidant overproduction. In this review, we critically discuss the main properties of free radicals, their implications in oxidative stress, and specific pathological conditions. In clinical medicine, oxidative stress can play a role in several chronic noncommunicable diseases, such as diabetes mellitus, cardiovascular, inflammatory, neurodegenerative diseases, and tumours.

Oxidative stress, aging, antioxidant supplementation and their impact on human health: An overview.

Aging is characterized by a progressive loss of tissue and organ function due to genetic and environmental factors, nutrition, and lifestyle. Oxidative stress is one the most important mechanisms of cellular senescence and increased frailty, resulting in several age-linked, noncommunicable diseases. Contributing events include genomic instability, telomere shortening, epigenetic mechanisms, reduced proteome homeostasis, altered stem-cell function, defective intercellular communication, progressive deregulation of nutrient sensing, mitochondrial dysfunction, and metabolic unbalance.

Effects of microbial transglutaminase levels on donkey cheese production.

Microbial transglutaminase (MTGase) is an enzyme widely used in the dairy sector to improve the functional properties of protein-based products via the formation of a network between protein molecules. The aim of this study involving cheese from the milk of donkeys was to evaluate the effects of treatment with MTGase at the concentrations of 0 (control), 5, 8 and 10 U/g milk protein on the cheese-making process parameters, as well as the physical and chemical characteristics of the resulting cheese. MTGase influenced the time of gel formation from rennet addition (P < 0.

Milk Products from Minor Dairy Species: A Review.

Milk processing is one of the most ancient food technologies, dating back around 6000 BC. The majority of dairy products are manufactured from cows, buffaloes, goats, and sheep; their production technologies are mostly standardized and have been widely investigated. Milk and dairy products from minor species are less important under the economic point of view, but they play a fundamental social role in many marginal and poor areas.

Chemical-Sensory Traits of Fresh Cheese Made by Enzymatic Coagulation of Donkey Milk.

Making cheese from donkey milk is considered unfeasible, due to difficulties in coagulation and curd forming. Two recent studies have reported the protocols for making fresh cheese by using camel chymosin or calf rennet, but the chemical and sensory characteristics of the products were not thoroughly investigated. The present paper aims to give a further contribution to the field, by investigating cheesemaking with microbial rennet and evaluating the chemical composition, total fatty acid, volatile organic compounds (VOCs) and sensory profile of the resultant product.

Progress in nutritional and health profile of milk and dairy products: a novel drug target.

There is an increasing focus on diet as a tool to maintain human health and prevent disease. Milk and milk products of ruminants are important source of fat and saturated fatty acids, which are not considered to be very favourable to human health, but are valuable sources of nutrients including bioactive fatty acids (FA), vitamins, and minerals, which can promote positive health effects. The nutritional characteristics of milk and dairy products are related to their composition, which depends on the source species, and varies due to numerous factors, among which the animal diet is the most important.

Fat content, energy value and fatty acid profile of donkey milk during lactation and implications for human nutrition.

Background And Aims: Milk contains numerous nutrients. The content of n-3 fatty acids, the n-6/n-3 ratio, and short- and medium-chain fatty acids may promote positive health effects. In Western societies, cow's milk fat is perceived as a risk factor for health because it is a source of a high fraction of saturated fatty acids.

Major whey proteins in donkey's milk: effect of season and lactation stage. Implications for potential dietary interventions in human diseases.

According to current literature, donkey's milk has been suggested as a hypoallergenic substitute in children affected by cow's milk protein allergy as well as a promising nutraceutical for aged people. However, the biologically active components of donkey's milk have not yet completely elucidated. In this framework this study is aimed at measuring α-lactalbumin (α-LA), β-lactoglobulin (β-LG), and lysozyme (LYS), the principal whey proteins in donkey's milk, in relation to lactation stage and production season.
