The aim of the study was to analyse the potential pea-peanut cross-reactivity using the mice BALB/c as a biological in vivo model in the research on immune response to peanut proteins (PnE). BALB/c mice were three-fold sensitised (on days 1, 7, and 21) by oral or intraperitoneal (IP) administration of PnE in 0.5 mg or 1 mg dose, with or without adjuvant – aluminum hydroxide gel (Alum). Serum immunoglobulins...
The effect of brewer’s spent grain addition (5, 10, 15 and 20% w/w) on selected properties of extrudates produced from corn grits with various moisture contents (12.5%, 13.5%, 14.5% and 15.5%) was analysed in this study. It was shown that an addition of brewer’s spent grain (BSG) to extrudates reduces expansion and increases density of the product. The changes are dependent on raw material moisture...
The aim of the study was to examine to what degree the consumers’ attitudes towards food and health influence their interest in sweets with special health-promoting properties, and to evaluate the effect of age, gender, education and family income on the interest in this kind of sweets. The research was carried out on a representative sample of 1000 adult Polish consumers. The survey instrument consisted...
The aim of this study was to evaluate the effect of rye flour extraction rate on the protein amino acids content and protein quality indexes (chemical score, CS, protein efficiency ratio, PER) of traditional rye bread and ginger cake and to compare them with conventional wheat bread. Rye flour with extraction rates of 1000 g/kg and 920 g/kg (F-1000 and F-920, respectively), were used. Amino acid content...
The hot convective drying of fresh tilapia fillets was evaluated in a heat pump dryer. The influence of the drying temperature (35, 45 and 55°C), hot air velocity (1.50, 2.50 and 3.50 m/s) and thickness (3, 5 and 7 mm) of the tilapia fillets on the moisture ratio and drying rate has been studied. It shows that drying process took place in falling rate periods. The experimental drying data of fresh...
This study was focused on substituting a part of wheat flour (WF) with whole meal barley (WBF), gelatinized corn flour (GCF) and both of them in balady bread, as an attempt to solve the shortage in wheat production. Chemical, rheological, color and sensory properties were determined. Stalling of balady bread was evaluated. It is found that the incorporation of WBF and GCF into balady bread improved...
Cashew is a tropical tree with immense commercial value and the use of its various parts in the confectionary, food, herbal and tanning industry has gained tremendous importance. Thus, the development of quality control method for routine analysis of various products of this widely used plant would be a great help to analysts. The phytochemistry of this plant has not been explored in detail. Anacardium...
Wild caught shrimp can have a shortened shelf life compared to farm raised shrimp due to handling and on-ship limitations. The loss of freshness in shrimp is partly due to autolytic reactions caused by endogenous enzymes such as polyphenol oxidase. The objective of this study was to determine the effect of sulfi tes combined with Modified atmosphere packaging (MAP) on the shelf life of non-frozen...
The aim of this study was to obtain starter cultures for fermenting sweet pepper, pattypan squash and tomatoes, composed of the autochthonous lactic acid bacteria (LAB), selected from spontaneously fermented vegetables of each particular species. Antibacterial activity of the LAB strains against eight test strains of pathogenic and undesirable in food bacteria, as well as good organoleptic quality...
Recently the supply situation of agricultural products has received increased attention due to a growing world population, the rising demand for animal products, an increased use of biomass for bioenergy production, highly volatile market for agricultural and food products and climate change, among other things. Therefore, a proper method to represent the total agricultural production is required...
The study aimed to determine associations between diet’s composition and serum antioxidant potential in 29 women aged 19–22 years. The participants completed self-report questionnaires concerning health condition, body measures, dietary habits and supplements taken, and 3-day detailed diet records. Fasting blood samples were collected to assess total antioxidant status (TAS) and ferric reducing antioxidant...
The study of secondary metabolism in plants is an important source for the discovery of bioactive compounds with a wide range of applications. Today these bioactive compounds derived from plants are important drugs such as antibiotics, and agrochemicals substitutes, they also have been economically important as flavors and fragrances, dyes and pigments, and food preservatives. Many of the drugs sold...
Increasing the potency of antihypertensive food-derived peptides is a critical and important step in the development of natural drugs for cardiovascular diseases prevention. We have proposed the egg-white protein precipitate (EWPP) obtained as a byproduct of cystatin and lysozyme isolation as a potential source of ACE-inhibitory peptides derived by pepsin digestion. The results indicated that hydrolysis...
Microbiological and sensory evaluations of bread and ketchup supplemented with β-D-glucan hydrogels isolated from wheat, oat, barley, and rye were carried out. Adding hydrocolloids did not affect sensory parameters of bread negatively; moreover rye and oat β-D-glucans improved the total tastiness of bread. Water activity values in fortified breads showed β-D-glucans, except isolated from oat, as elements...
Flavonols and flavones are antioxidants of plant origin with a benefi cial role in the prevention of different diseases. Therefore it is important for their content in various foods to be measured in order to be able to judge on their potential for disease prevention. The aim of the study is to present precise and representative data for flavonols and flavones content of Bulgarian foods from Malvaceae...
The eating disorders have been reviewed based on state-of-art of contemporary psychology, medicine and nutrition science, with a special emphasis put on different symptoms and forms, origins and testing methods. Among promoting eating disorders, bulimia nervosa, binge eating disorder, night eating disorder, sleep-related eating disorder are among offi cially approved and investigated. Among disorders...
Phenolic compounds are important plant metabolites associated with the plant’s defence reactions in conditions of biotic and abiotic stress. Heterotrophic organisms are not capable of synthesizing phenolic compounds, but absorb them with foods of plant origin. Many of them exhibit antioxidant activity in chemical and biological assays. This study examined whether these compounds are able to protect...
The objective of this study was to evaluate the quality and nutritive value of meat of bulls receiving wheat or maize DDGS (distillers dried grains with solubles) as a source of protein in a feed ration. The Hereford bulls were fed maize silage, hay and concentrates. The factor differentiating the feeding of experimental groups was the composition of concentrates. All concentrates contained cereal...
The purpose of present study is to investigate the efficiency of different kinds of Turkish commercial bleaching earth materials for changes in different colour pigment concentrations in neutralized sunfl ower oils. The bleaching experiments were performed in a pilot system under at stable vacuum (50 mmHg) and temperature (100ºC) for 30 min. By examining the changes in chlorophyll, β-carotene and...
