Background. The aim of this study was to assess the influence of the consumption level of plant sterols naturally occurring in diet on the lipid profile in obese women with dyslipidemia. Materiał and methods. The study population was primarily comprised of 120 obese women aged over 55 from Poland, with twenty seven subjects dropping out of the study due to the inclusion and exclusion criteria. Anthropometric...
Background. Osmotic dehydration is a process of the partial removal of water which is based on immersion of materiał having cellular structurc in a hypertonic solution. Osmotic dehydration is used as a pretreatment for the dehydration of foods before they are subjected to further processing such as freezing, freeze drying, vacuum drying. Management of spent syrup is one of the most important problems...
Introduction. One side effect of antihypertensive drugs is their impact on nutritional status and metabolism. The purpose of this study was to assess the nutritional and biochemical parameters in spontaneously hypertensive rats following treatment with antihypertensive drugs. Materiał and methods. The experiment was performed on 50 male spontaneously hypertensive rats (SHR), which were assigned to...
Background. Drying of terebinth fruit was conducted to provide microbiological stability, reduce product deterioration due to chemical reactions, facilitate storage and lower transportation costs. Because terebinth fruit is susceptible to heat, the selection of a suitable drying technology is a challenging task. Artificial neural networks (ANNs) are used as a nonlinear mapping structures for modelling...
Although it is weli known and identified that drug-drug interactions exist, the recognition of importance of food and drug interactions to practice has been growing much slower. On the other hand, drug-food/nutrient interactions continue to grow with the common use of medications. Beside the awareness of this type of interactions, food-drug interaction studies are critical to evaluate appropriate...
Background. Yoghurt is a fermented milk of unique sensory, nutritive and dietetic value offered in a variety of types and in different flavours. Vegetables belong to the group of food products rich in antioxidant substances (e.g., vitamin C, carotenoids, tocopherols, polyphenols) which regular consumption lowers the risk of many diseases including cancers and cardiovascular disorders. The aim of the...
Background. Healthy foods have been met with marked success in the last two decades. Lupine flours, protein concentrates, and isolates can be applied as a substance for enriching different kinds of food Systems such as bakery products, lupine pasta, ice cream, milk substitutes. Imitation processed cheese is made from mixtures of dairy and/or non dairy proteins and fat/oils and is variously labeled...
Background.Bread can be a good source of nutrients as well as non-nutrient compounds. This study was designed to assess the effect of adding of sourdough and whey proteins to wholemeal (WM) bread produced by bake-off technology on Chemical composition and bioavailability of proteins, calcium, phosphorus, mag- nesium and iron content in Wistar rats. Materiał and methods. Wholemeal breads were baked...
Proteins are one of the primary components of the food, both in terms of nutrition and function. They are main source of amino acids, essential for synthesis of proteins, and also source of energy. Additionally, many proteins exhibit specific biological activities, which may have effect on functional or pro-health properties of food products. These proteins and their hydrolysis products, peptides,...
Background. Protein quantity in diet including the digestibility and bioavailability of protein is of importance to eradicate undemutrition in developing countries. Bread protein is an incomplete source as it lacks an essential amino acid lysine. When they are combined with other plant foods like pulses and legumes, they become a complete source of protein. Since bread is most common staple food the...
Background. Fłaxseed (Linum usitatissimum L.) is an important source of phenolic compounds, mainly lignans. Antioxidant capacities of flaxseed extracts that contain the compounds have been reported earlier. However, there is a lack of accessible information about their activity against lipid oxidation in meat products. Therefore, the effect of ethanolic flaxseed extracts (EFEs) on lipid stability...
Background. Quince has many health benefits. Dried quince has been used as a tea for centuries. The aim of this study was to investigate the influences of two drying methods on the antioxidant activity of the quince. Materiał and methods. Fifty two fresh Iranian quinces (Cydonia oblonga) were obtained from different parts of Shiraz. Half of the quinces were peeled and both peel and flesh immediately...
Dietary fibre is a group of food components which is resistant to digestive enzymes and found mainly in cereals, fruits and vegetables. Dietary fiber and whole grains contain a unique blend of bioactive components including resistant starches, vitamins, minerals, phytochemicals and antioxidants. Dietary fiber which indigestible in human smali intestinal, on the other hand digested completely or partially...
Background. The study aimed to assess the risk related to consumption of low-fat dairy products by expectant and lactating women. Material and methods. A survey was used to verify the popularity of such products among expectant and lactating women and then the content of Cd and Pb in low-fat dairy products was determined. Results. In the group of expectant women consuming dairy products, nearly 93%...
Background. 6-Gingerol is one of the most pharmacologically active and abundant components in ginger, which has a wide array of biochemical and pharmacologic activities. In recent years, the application of microwave-assisted extraction (MAE) for obtaining bioactive compounds from plant materials has shown tremendous research interest and potential. In this study, an efficient microwave-assisted extraction...
Background. Proteomic analysis is emerging as a highly useful tool in food research, including studies of food allergies. Two-dimensional gel electrophoresis involving isoelectric focusing and sodium dodecyl sulfate polyacrylamide gel electrophoresis is the most effective method of separating hundreds or even thousands of proteins. In this study, albumin and globulin fractions of pea seeds cv. Ramrod...
Background. Parsley leaf is a rich source of natural antioxidants, which serve a lot of functions in human body and prevent food from oxidation processes. The aim of the study was to investigate the influence of different extraction solvents and times of extraction on natural antioxidants content. Owing to the knowledge of the properties of extracted components and solvents, as well as their interactions,...
Background. The purpose of this study was to investigate the relationship of biochemical (enzymes) and nutritional components in the selected honey samples from Malaysia. The relationship is important to estimate the quality of honey based on the concentration of these nutritious components. Such a study is limited for honey samples from tropical countries with heavy rainfall throughout the year....
It is known, that lipid peroxidation is one of the main factors limiting the quality and acceptability of meat and other animal tissues. The current data conceming connection of heme and peroxidation were summarized and analysed here. The muscle food compounds that are most influenced by oxidative processes include unsaturated fatty acids of lipids, amino acids of proteins and heme groups of pigments...
Background. Epidemiological research has identified a relationship between maternal physical activity, early nutrition and infant birth weight with likelihood of developing future diseases. The aim of the study was to determine a relationship between gestational weight gain and physical activity during pregnancy to the nutritional status of newborns. Material and methods. The presented study was conducted...
