In order to ensure microbiological safety of food stuffs a comprehensive and integrated approach needs to be applied to production process, comply with all obligatory quality standards at each step.In present work a microbiological quality of selected ripened cheeses (5) and liquid dairy products (5) was analyzed using following tests available in TEMPO system: YM – yeasts and molds, STA – the number...
The aim of this study was to investigate changes of volatile compounds in Rokpol blue cheeseduring storage under different temperature conditions (4℃, 25℃, 35℃). Headspace solid-phasemicroextraction (HS-SPME) was used to isolate volatile compounds from the matrix and GC/MS wasused for compounds separation and identification. Received aroma profiles were showed in the analyzed cheese and statistical...
An evaluation of lesions in the livers of Black and White cattle, aged 4 to 7, naturally infested with Fasciola hepatica was performed. The studies included a comprehensive analysis of histological lesions and liver enzyme activities determined with histochemical methods depending on the degreeof natural Fasciola hepatica in festation. The studies revealed increased number of reticular fibres, an...
The grain of winter rye (Secale cereale L.) originated from a field experiment conducted in the years 2011–2013 at the Didactic-Experimental Centre of the University of Warmia and Mazury inTomaszkowo (53⁰72 N; 20⁰42 E) in Poland. The aim of the study was to determine the yield of winterrye and its components and the content of proteins, starch and selected mineral components (P, K,Ca, Mg, Cu, Fe,...
In order to increase amaranth oil availability to the consumers an encapsulation process by spraydrying was applied. Based on the confocal Raman microscopy imaging technique supported bycomputer image analysis an algorithm for detailed visualization of oil presence on the surface orinside of aggregated microcapsules was performed. Those information are crucial in terms of oilbioavailability as well...
The goal of the experiment was to specify the impact of glycerides of medium-chain fatty acid (AveMix MCT) additives and a herbal additive (AdiSan) on production results in turkeys. The research material covered 160 BIG-6 turkeys (hens) divided into 2 groups, 4 series in each group. The experiment lasted 15 weeks. The control group received compound feed, without additives, of organicacids and herbs...
The aim of study was to evaluate the sensitivity of selected microbial groups cultured on solidmedia and soil-dwelling microorganisms to metazachlor (Fuego 500 SC), a mixture of diflufenican+ mesosulfuron-methyl + iodosulfuron-methyl-sodium (Alister Grande 190 OD), and a mixture of terbuthylazine + mesotrione + s-metolachlor (Lumax 537.5 SE). The tested microorganisms were: Azotobacterspp.,Arthrobacterspp...
The effects of increasing nickel contamination of soil on selected macroelement uptake byIndian mustard (Brassica junceaL. Czern) and application of natural zeolite, raw and modified halloysite were investigated in this experiments. In a vegetative-pot experiment, four different level of nickel contamination, i.e., 0 (control), 80, 160, 240, 320 mg · kg–1were applied in an analytical grade NiSO4·7H2O...
The paper presents the results of a 3-year-long (2008–2010) study on the dynamics of weedinfestation of spring barley sown after different previous crops (potato, spring wheat and springbarley, in 1- and 2-year sequences of the same crop) in four-field crop rotation systems with 25, 50 and75% shares of spring barley. Weed infestation was evaluated at the barley tillering stage and beforeharvesting,...
Two pig fattening trials were conducted, one in summer and one in winter. A total of 96 crossbred pigs were analyzed, including 48 animals in each experiment. The pigs were randomly assigned to 4 groups: group 1 – pigs kept in litter-less pens and fed a complete dietad libitum, group 2 – pigs kept in litter-less pens and fed a complete diet supplemented with fresh alfalfa(experiment 1) or alfalfa...
The aim of the study was to compare the share of hatchery-reared lake trout Salmo truttam.lacustrisin catches of fingerlings in the upper Wda and the Pilica Rivers in Autumn, following the stocking fish in spring 2005. Larvae in number of 40 thousand had been previously exposed to the thermal shock procedure (temperature decrease from 8.0 to 2.5oC for 2 hours, and back to initialvalue), then released...
In this study comparison of quality parameters and chemical composition between cold-pressedoils obtained from 6 different rapeseed varieties, including double improved (RO), high-oleic (HORO)and yellow-seeded (YSRO), has been conducted. A clear correlation between fatty acid composition and oxidative stability of oils was observed. Variety-dependent variation in the content of individual tocopherols...
The aim of this study was to determine the state of hygiene of milk supplied through various forms of direct sales; purchased from the individual producer, a dairy delivering products to the consumer’s home, and from the milkomats located in the Tri-City. The milk samples were marked todetermine the OLD at 30℃, the presence and enumeration of Staphylococcus aureusand the presenceand number of E. coli...
The aim of this work is an attempt to define the role of intelligent packagings to make the course of logistic food processes more efficient. The implementation of the aim happened by conducting the surveys concerning the meaning of intelligent packagings advantages for the chosen participants of logistic processes in the chain of supply.The studies were questionnaires and included the following elements...
The aim of this study was to determine seasonal changes in the occurrence of carbon forms inwater and bottom sediment in lakes with a different type of mixing. The study was conducted in five urban lakes located in Olsztyn: Track, Sukiel, Podkówka, Redykajny and Tyrsko. The research was carried out in March, April, August and November. We analyzed TOC, DOC and IC in samples of water collected near...
The experimental materials comprised 180 carcasses of European roe deer (bucks, does and kids) hunter-harvested in forest (90 carcasses) and field (90 carcasses) habitats. Zoometric measurements of carcasses were carried out and the percentage shares of edible and non-edible components were determined.Significant differences were found in carcass size and weight between roe deer from different sexand...
The object of the study was to compare the effect of low- and high-pressure homogenization of milk on fat digestion in vitro. The extent of lipid digestion by lipase with and without addition of bile salts and phospholipid was monitored by determining the release of fatty acids. Additionally changes in the milk fat emulsion were monitored during the process of lipolysis. Higher amounts of fatty acids...
This paper analysed the impact of rapeseed size and storage conditions on content of phosphorus and phospholipids in seeds and oils.
