Background. Arisarum vulgare is screened and its total phenolic compounds and total flavonoid contents were measured. In addition, the antioxidant capacity of the methanol-water (7:3) extract of this plant is evaluated by DPPH (2,2-diphenyl-l picrylhydrazyl) and ABTS (2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic)) tests expressed by Vitamin C Equivalent Antioxidant Capacity (VCEAC). HPLC analyses...
Background. Tarhana, a wheat-yoghurt fermented mixture, is considered as a good source of saccharides, proteins, some vitamins and minerals. Moreover, their preparation is inexpensive and lactic acid fermentation offers benefits like product preservation, enhancement of nutritive value and sensory properties improvement. The aim of this work was to evaluate changes of some chemical parameters during...
Introduction. As regards a significant intake of wild growing edible mushrooms, especially in East and Central Europe, concentrations of toxic elements should be periodically analysed. The aim of the study was to assess changes in concentrations of selected trace elements (Ba, Cd, Co, Cu, Fe, Hg, Mn, Ni, Pb, Sr and Zn) in a mushroom species, Xerocomus badius. Material and methods.Xerocomus badius...
Introduction. The ageing in men, the most frequent pathologic lesions affecting the prostatic gland in this period are benign prostatic hyperplasia (BPH) and prostate cancer (PC), the course of which may be influenced by the improper nutritional status of patients and their nutritional habits. The aim of this study was, therefore, to evaluate the nutritional status and eating habits of men diagnosed...
Background. The present work was designed to appraise how different extraction solvents and techniques affect the extractability of antioxidant and antimicrobial components from Lantana camara (L. camara) flowers. Material and methods. Four extraction solvents including 100% methanol, 80% methanol, 100% ethanol and 80% ethanol coupled with three extraction techniques namely stirring, microwave-assisted...
Background. The quality of dairy products, raw milk in particular, depends on many factors. Low bacterial and somatic celi counts are basic determinants of the appropriate raw milk quality. The objective of the work was to assess the effect of selected factors, that is, the age of cows and their daily milk performance, on cytological quality (somatic celi count) and energy value of milk produced at...
Background. Legumes are a good source of protein, and are also abundant in carbohydrates, B-group vitamins, dietary fibre and mineral compounds. Material and methods. This work evaluates the retention of ash, eleven minerals and two heavy metals in products obtained from two common bean cultivars harvested before reaching fuli maturity, with a dry matter content of about 40%. Analyses were conducted...
Background. There is increasing evidence to suggest that a vegetarian diet low in fat and high in complex carbohydrates offers the potential for decreasing the risk of chronie disease. However, there is little information about the effect of vegetarian diets on resting metabolic rate (RMR). The objective of this study was to determine the association of vegan diet with RMR and body composition and...
Background. Due to the health-promoting value of black radish, authors decided to investigate the feasibility of forming - from its roots - chips, using the process of microwave-vacuum puffing. In order to produce desirable quality of chips, there is a need to determine the most advantageous values of process parameters. The main goal of the paper is to investigate the possibility of determining the...
Introduction. Fish quality is traditionally controlled by chemical and microbiological analysis. The non-destructive control presents an enormous professional interest thanks to the technical contribution and precision of the analysis to which it leads. This paper presents the results obtained from a characterisation of fish thawing process by the ultrasonic technique, with monitoring thermal processing...
Background. Microwave heating is one of the most attractive cooking methods for food preparation, commonly employed in households and especially in restaurants for its high speed and convenience. The chemical constituents of oils that degrade during microwave heating do so at rates that vary with heating temperature and time in a similar manner to other type of processing methods. The rate of quality...
Background. Performic acid has recently become available on a commercial scale for potential use in wastewater disinfection and can become an innovative biocide for various purposes in food processing. The aim of our study was: 1) to investigate the antimicrobial resistance of performic acid as high active and non toxic Chemical disinfectant against Escherichi coli (hygiene indicator test microorganism...
Background. Chemical composition and medicinal potential of Centella asiatica (C. asiatica), Cedrus deodara (C. deodara) and Artemisia persica (A. persica) prompts the need to investigate antioxidant attributes of these species as altemative source of natural antioxidants. The main aim of the present investigation was to evaluate the antioxidant potential of methanolic extracts of these plants towards...
Background. Kunun-zaki is an indigenous non alcoholic beverage in Nigeria which has been reported to contain high nutritional values because of the raw materials from which it is made. Therefore, this research was carried out to investigate the antioxidant and antimicrobial activities of extracts of some of the spices used in the production of the beverage. Material and method. The spices; Xylopia...
Introduction. This study evaluated the correlation between selected socioeconomic and lifestyle characteristics and 10-year risk of fracture in persons aged 65+, living in small towns in the north-east of Poland. Material and methods. 267 individuals (76 males and 191 females) aged 76.9 ±2.5 years, living in small towns in the north-east of Poland in independent households, took part in the study...
Introduction. This paper constitutes a supplementary study of the research conducted to assess accumulation efficiency of selected trace elements by Xerocomus badius fruiting bodies picked in some regions of Poland in selected years. Material and methods. Atomic absorption/emission spectrometry techniques (FAAS and AES) were applied to determine in the fruiting bodies of this mushroom species the...
Background. Texture is probably the single most critical quality factor associated with the consumers’ ultimate satisfaction with a poultry meat product and can be affectcd by several factors including the type of feed used for chickens fattening. The use of probiotics for meat and carcass quality improvement has been questioned, while the possibility of deposition of essential oils in various muscle...
Background. High consumption of food products rich in rapidly digested starch, saccharose, glucose and fructose, animal fat and low physical activity are the major risks of overweight, obesity and cardiovascular diseases. The aim of this study was to evaluate the effect of resveratrol on the activity of selected enzymes, heme oxygenase-l (Hmoxl) and glutathione reductase (Gsr) gene expression, as...
Background. Recent epidemiological studies show a high incidence of diseases associated with disturbances in protein metabolism, causing gluten intolerance and consequently the occurrence of celiac disease. Gluten, as a specific protein fraction of wheat, rye, barley and oats, cannot be metabolized in gastrointestinal tract of patients suffering from celiac disease. The prevalence of this disease...
Background. Roselle seeds are waste that is left behind during processing of roselle for juices or other roselle related products. Disposing of waste is highly undesirable both economically and environmentally. Roselle seeds contain high amount of protein, crude fibers, fats, and carbohydrates. The objective of this study was to determine the effect of different processing techniques (roasting using...
