ASSESSMENT OF FREEZING PRE-TREATMENTS FOR THE FREEZE DRIED OF APPLE SLICES

Publié en ligne: 31 Dec 2013
Pages: 3 - 14

Résumé

Abstract

The effect of freezing rate on the quality of dried Jonagold and Idared was studied. Apple slices underwent various pre-treatments, i.e. freezing in household freezer (freezing rate: 0,5 °C/min), contact plate freezing (2 °C/min) and vacuum-freezing (3 °C/min). The quality of the freeze dried product was then evaluated in terms of water activity, hardness, color and rehydration. The freezing in household freezer (slow freezing rate) significantly reduces the duration of the freeze drying process and consequently the process costs. The slow freezing rate allows the growth of large ice crystals at the beginning of the freeze-drying process, this fact should consequently lead to larger pores and injured cell walls and thus to shorter freeze drying time. Quality of the freezing in household freezer product was assessed as higher than the quality of the other freezing pre-treated material. Slow freezing rate resulted softer texture and higher rehydration capacity, than that of other pre-treated samples. In all cases, slow freezing lead to lower final moisture content, total color difference and water activity.

Pages: 129 - 136

Résumé

Abstract

the paper deals with verification of the effects of the electrolyzed NaCl-water solution where a new possibility for an alternative procedure to disinfect water is provided. The experiment was done in two chicken breeding halls where the solution was used to disinfect the stable premises and at the same time it was applied into the feed water. The effects of disinfection were verified directly in the stable premises at the interval of 20, 40, 60 minutes after application. Staphylococci and Streptococci and Enterococci were inactive always after 60 minutes of effect. There was significant decrease in the number of total number of microorganisms. An evaluation of the qualitative features of the produced chicken meat, focused mainly on the PSE meat disorder, was a part of the examination, too. After the research was finished, the chickens were slaughtered at the industrial slaughterhouse and samples of the meat were taken (gradually 157 pieces in total) from the individual halls and analysed. The determined share in water loss by dripping was the most significant of the monitored indicators, which could suggest a possible development of the PSE problem, however, the meat colour and the pH values did not confirmed this. The values of pH, colour and loss of water (dripping) ascertained, processed by the T-test did not confirm the hypothesis of the assumed possible differences in occurrence of critical values of these indicators in both groups observed.

Pages: 115 - 119

Résumé

Abstract

Relevance of the study is associated with reduced energy intensity of the process heat demand by improving the systems and control algorithms of automatic energy management in buildings. This paper presents a system for power management of individual modules with interaction via the Ethernet, allowing measuring the qualitative and quantitative performance of network communication protocols of different levels of performance monitoring in real time. The difference of the developed intellectual automatic control system consisting of separate modules with interaction via the Ethernet, there is no separation devices for simple and intelligent - all the devices are intelligent, the controller is a separate module, and its functions are performed by the control unit.

Pages: 121 - 127

Résumé

Abstract

the aim of our study was to evaluate influence of probiotic agents (Lactovita) and seaweed extracts (Biopolym) with antidiarrheal effects on the prevention of diarrhoea in calves. In the experiment 22 experimental and 22 control calves were observed. The results of the observed incidence of diarrhoea in the control and experimental groups showed a positive effect of probiotic Lactovita and seaweed extracts Biopolymer. 32% of calves in the experimental group and 45% of calves in the control group became sick. Unfortunately, we could not demonstrate the statistical significance of these differences. The weight gains found in the 4th week after birth were by 37.6% higher in the group with Lactovita and Biopolym than in the control group.

Pages: 129 - 136

Résumé

Abstract

the paper deals with verification of the effects of the electrolyzed NaCl-water solution where a new possibility for an alternative procedure to disinfect water is provided. The experiment was done in two chicken breeding halls where the solution was used to disinfect the stable premises and at the same time it was applied into the feed water. The effects of disinfection were verified directly in the stable premises at the interval of 20, 40, 60 minutes after application. Staphylococci and Streptococci and Enterococci were inactive always after 60 minutes of effect. There was significant decrease in the number of total number of microorganisms. An evaluation of the qualitative features of the produced chicken meat, focused mainly on the PSE meat disorder, was a part of the examination, too. After the research was finished, the chickens were slaughtered at the industrial slaughterhouse and samples of the meat were taken (gradually 157 pieces in total) from the individual halls and analysed. The determined share in water loss by dripping was the most significant of the monitored indicators, which could suggest a possible development of the PSE problem, however, the meat colour and the pH values did not confirmed this. The values of pH, colour and loss of water (dripping) ascertained, processed by the T-test did not confirm the hypothesis of the assumed possible differences in occurrence of critical values of these indicators in both groups observed.

Pages: 137 - 144

Résumé

Abstract

up to date information systems collect data from technological process, facts about production, reproduction and health of animals. On the base of all figures of these measurable values and evaluation of observable characteristics we can do the classification of the total rate of animal welfare. Physical activity of animals is affected by many factors during the day, especially satisfying basic needs, i.e. feed intake, social manifestations, etc. Vitalimeter is recording physical activity of the animal, including the type of movement, standing and lying time, number of leap.

Pages: 145 - 151

Résumé

Abstract

The article view on the effect of the extensive breeding conditions on health state of sheep in foothill areas of the South Bohemian region. Very negatively affects the health of sheep presence of parasitic infection in the herd. Among the factors indicative of the normal process of physiological functions and thus the health of sheep include haematologic and biochemical parameters of blood. Samples of blood and excrements were collected and divided by breeds of sheep and sampling time. It was done Faeces examination of excrements and was determined number of erythrocytes and leukocytes, haematocrit, haemoglobin, content of zinc and copper in blood and differential leucocytes count. Haematological and biochemical parameters were observed for all samples in the physiological range, despite the simultaneous parasitic contagions of examined animals.
