The aim of the study was to determine the possibility of reducing fat content in fatty sponge-cake products by addition of inulin. 200 g/kg, 440 g/kg, 680 g/kg and 100% of fat was substituted with 20 g/kg, 35 g/kg, 50 g/kg, and 62.5 g/kg of inulin, respectively. The authors used two types of fat: with low and high content of trans isomers – containing 2.1 g/kg and 511.2 g/kg of fatty acid methyl esters...
Five percent of consumed oxygen produces a number of reactive oxygen species (ROS) including free radicals and other chemical products such as malondialdehyde (MDA). MDA increases lipid peroxidation such as low density lipoproteins cholesterol (LDL-c). Melatonin can decrease MDA and lipid peroxidation, but there are limited data about melatonin supplementation on MDA and lipid peroxidation of women...
The aim of this study was to reduce the level of homocysteine (Hcy) by high-methionine dietary supplementation of folic acid and to evaluate changes in lipid parameters in blood serum of experimental rats. The animals were randomly divided into seven groups (n=6, male), and were fed seven different diets for 52 days. The rodents were fed with the AIN-93G semi-synthetic diet (group I), supplemented...
Brassica vegetables, including caulifl ower, are characterized by a high number of valuable metabolites, which act effectively in the cancer chemoprevention, as was already revealed by several studies. This work investigates the effect of the type of container: low density polyethylene (PE-LD) packages and oriented polystyrene (OPS) packages on selected quality parameters in frozen caulifl ower. The...
This study intended to provide biopolymer films used as food packaging, which will result in reducing environmental pollution produced by the activities of synthetic food packaging. We used zinc oxide nanorods (ZnO-nr) and we prepared nanocomposite films by means of solvent casting. FTIR and SEM were employed to characterize the final films. SEM images revealed that ZnO-nr particles were homogenously...
The objectives of this article were to determine the content of total dietary fibre (TDF) as well as of its fractions – soluble dietary fibre (SDF) and insoluble dietary fibre (IDF) of different cereals grown by conventional and organic farming in Macedonia, as well as to fi nd out the influence of the cereal type and farming method on their values. Standardized enzymatic-gravimetric method (Megazyme...
Ice cream was prepared with exopolysaccharide (EPS)-producing Lactobacillus plantarum YW11 by direct inoculation (DI), addition of prefermented skim milk (FSM), or addition of the lyophilized powder of the YW11 strain (LP) into the ice cream mix. After 4 weeks of storage, viable counts of the YW11 strain decreased in all groups by 0.8–1.61 log cfu/g. Furthermore, ice cream made using the LP method...
This study evaluated the antioxidant activity of ethanol extracts of Osmanthus fragrans (Thunb.) Lour. flowers (EOF) and identifi ed phenolic compounds in EOF using liquid chromatography-mass spectrometry. Nine compounds, 3-O-caffeoylquinic acid, caffeic acid 4-O-glucoside, salidroside, 5-O-coumaroylquinic acid, 4-O-coumaroylquinic acid, acteoside, ligustroside, fucosterol and arjunolic acid were...
Microalgae are a group of microorganisms used in aquaculture. The number of studies regarding their use as a functional food has recently increased due to their nutritional and bioactive compounds such as polysaccharides, fatty acids, bioactive peptides, and pigments. Specific microalgal glucans (polysaccharides) can activate the immune system or exert antioxidant and hypocholesterolemic effects....
This study was aimed at determining the effect of acetylation degree and crosslinking of retrograded starch with adipic acid on selected rheological properties of prepared pastes and gels. The esterification of retrograded starch allowed obtaining preparations with various degrees of substitution with residues of acetic (0.7–11.2 g/100 g) and adipic acids (0.1–0.3 g/100 g). Acetylation and crosslinking...
The presented study revealed that there were changes in the phenolic compounds profile of extract of wild thyme (Thymus serpyllum L.) after γ-irradiation at the dose of 5 kGy. Ethanolic extracts of irradiated and non-irradiated herb were prepared and their compounds were analyzed by RP- -HPLC-DAD technique. Between thirty two detected constituents, twelve phenolic compounds classifi ed as hydroxybenzoic...
Rosemary (Rosmarinus officinalis L.) transglutaminase (RTGase) was used to cross-link whey protein isolate (WPI) and its ability to induce gelation was investigated. The rheological and textural properties of WPI were improved with RTGase treatment. Set-type yoghurts fortifi ed with 1% WPI powder treated with RTGase at the level of 2.5 and 10 unit/g protein were studied. Chemical, rheological, textural...
The objective of this study was to determine the sensory quality of a specific Polish traditional product made from cured and then smoked goose meat (półgęsek) in relation to its volatile compounds and chemical composition. In general, the examined samples contained 66.2% water, 12.2% fat, 17.9% protein, 1.8% connective tissue, and 2.3% NaCl. Moreover, 47 volatile compounds were identifi ed and quantified...
The objective of this study was to investigate the colour stability and lipid oxidation of beef under different packaging methods. The muscles longissimus lumborum were randomly packed in vacuum or modifi ed atmosphere packaging (MAP, 80% O2 , 20% CO2 ). Both packages were aged at 4°C for 7, 14 and 21 days. After each ageing time, samples were displayed in a refrigerator for 2, 4 and 6 days. Colour...
