Ozone treatment allow inactivate microorganisms to achieving lower survival rates by ozone dose The results demonstrated that a linear correlation between parameters p and k in Weibull distribution, providing an opportunity to calculate a fitted equation of the process.
The aim of this study was to evaluate the influence of different starch liberation and saccharification methods on microbiological contamination of distillery mashes. The quality of agricultural distillates was also evaluated.
When applying the pressureless liberation of starch PLS and malt as a source of amylolytic enzymes, the lactic acid bacteria count in the mashes increased several times during fermentation.
The mashes obtained using the pressure-thermal method and malt enzymes revealed a similar pattern. Samples prepared using cereal malt exhibited higher concentrations of lactic and acetic acids, as compared to mashes prepared using enzymes of microbial origin. As a result, fermentation of both mashes prepared with microbial origin enzyme preparations and with barley malt resulted in satisfactory efficiency and distillates with low concentrations of aldehydes.
Suitability of the probiotic lactic acid bacteria strains as the starter cultures in unripe cornelian cherry Cornus mas L. This study examines the influence of lactic acid fermentation on iridoid and polyphenolic compounds in unripe Cornus mas L. Fermentation was carried out at room temperature over 6 weeks. Eight versions of the fermentation process were conducted: The polyphenolic compounds, iridoids and antioxidant activities were examined in the products obtained.
After fermentation, the polyphenols detected were: Loganic acid and cornuside were found to be present in both the fermented fruits and the brines. The tested microorganisms produced varying amounts of lactic acid and had varying degrees of impact on the content of biologically active compounds. Unripe cornelian cherries fermented with probiotic strains could be used as an innovative pro-health product. Ozone in the Food Industry: The food contamination issue requires continuous control of food at each step of the production process.
High quality and safety of products are equally important factors in the food industry. They may be achieved with several, more or less technologically advanced methodologies. In this work, we review the role, contribution, importance, and impact of ozone as a decontaminating agent used to control and eliminate the presence of microorganisms in food products as well as to extend their shelf-life and remove undesirable odors.
Several researchers have been focusing on the ozone's properties and applications, proving that ozone treatment technology can be applied to all types of foods, from fruits, vegetables, spices, meat and seafood products to beverages.
A compilation of those works, presented in this review, can be a useful tool for establishing appropriate ozone treatment conditions, and factors affecting the improved quality and safety of food products. A critical evaluation of the advantages and disadvantages of ozone in the context of its application in the food industry is presented as well.
Implementation of chemometrics in quality evaluation of food and beverages. Conventional methods for food quality evaluation based on chemical or microbiological analysis followed by traditional univariate statistics such as ANOVA are considered insufficient for some purposes. More sophisticated instrumental methods including spectroscopy and chromatography, in combination with multivariate analysis - chemometrics, can be used to determine food authenticity, identify adulterations or mislabeling and determine food safety.
The purpose of this review is to present the current state of knowledge on the use of chemometric tools for evaluating quality of food products of animal and plant origin and beverages.
The article describes applications of several multivariate techniques in food and beverages research, showing their showing their role in adulteration detection, authentication, quality control, differentiation of samples and comparing their classification and prediction ability.
The character of plum brandies depends on a unique aroma profile of the plum and the microbiota present on the surface of the fruits, as well as yeast used for fermentation. An estimation of the odour activity values OAVs of the volatile compounds was also conducted. Regardless of whether the fermentation was carried out using Saccharomyces bayanus wine yeast or by native microflora present on plums as well as raisins, the efficiency of this process was high and ranged between An evaluation of the individual aromatic effect of chemical compounds present in tested distillates, in terms of their OAVs, revealed that the highest OAVs were reached with isovaleraldehyde.
Polyphenolic extracts of cherry Prunus cerasus L. The objective of this study was to evaluate the possibility of using polyphenolic extracts from cherry and blackcurrant leaves as natural antimicrobial agents in meat products. The polyphenolic composition of the extracts was analyzed and their impact on the microbial quality, lipid oxidation, color, and sensory evaluation of pork sausages was studied.
Polyphenolic extracts were obtained from leaves collected in September. The total polyphenolic content in sour cherry leaf extract was 1. Analysis of the polyphenol profile of each extract revealed two major groups: After chilling the sausages for 14 and 28 days, the extracts caused significantly lower MDA generation, indicating an antioxidant effect.
Color changes after 28 days of storage were perceptible in the case of all treatments, with and without polyphenols. The application of sour cherry and black currant leaf extracts increased the shelf life of vacuum-packed sausages.
Both extracts enhanced the microbial quality of the pork sausages over 14 days of refrigerated storage. Sour cherry leaf polyphenols were more effective against almost all studied groups of microorganisms. The development of the parameters of ozone decontamination method assuring the least possible losses of biologically active substances essential oils and polyphenols and their activity in common juniper Juniperus communis L.
This process was examined in two mountain areas in Polish Carpathians: Lower Beskid and Gorce. It was found out, in both cases, that secondary vegetation succession and forest encroachment are taking place. The area covered by forest has increased significantly in the relation to non-forest area with the course of time. Two different approaches to investigate vegetation succession are presented. Glades may be treated as areas where reforestation occurs or the forest patches might be treated as the type of land cover which expands.
Models of reforestation processes. A climax community in the Beskidy Mountains is a forest. The natural mountain landscape has been changed considerably by agriculture, which lasted for many centuries. Reforestation is a quite common phenomenon in case of exclusion from agricultural use. Lower Beskid and Gorce Mts. It was found out that there is a few specific ways in which reforestation may occur. As a result of field research in Gorce, four models of succession were created. Apart from that, the phenomenon of frontal reforestation was examined in detail in Lower Beskid.
This resulted in distinction of four types of forest-field boundary and two types of elements configuration. The nature of settlement in the Hutsulshchyna region has changed considerably over time. Historically, farms were established in isolation and were mostly self-sufficient; the distance between them being considerable. Farms were concentrated only in villages nestled deep in valleys.
During the war, a large number of people were killed or deported because of their support for the Ukrainian Insurgent Army. Under Soviet occupation, a policy of collectivization was put into effect and kolkhozes collective farms were established. Following the collapse of the USSR , a gradual economic transformation brought about many changes, notably that the descendants of former land owners regained their lost property. Today, the region is becoming depopulated and spatial patterns are changing once again.
In this paper, Kosarysche Ridge is taken to be the area above the anthropogenic timberline. The purpose of the research was to analyze the contemporary spatial distribution of farms as well as land use on Kosharysche Ridge. Reasons for the abandonment of farms were examined, and factors such as elevation, distance to the village center and administrative units were taken into account.
Land use changes were analyzed in relation to the slope of the surrounding area. Key factors affecting the intensity and direction of these processes were searched.
In addition, the present state of farms in existence prior to was investigated. Research has shown that the settlement system has changed substantially. Today, the establishment of farms off the beaten track and far away from each other is no longer as important as it used to be.
Urbanization is taking place and an increasing number of people are moving to villages and towns. The depopulation rate increases with increasing elevation and distance to the village center. On the other hand, there is no unambiguous link between farm abandonment and administrative unit.
Mowed areas are located on the gentlest of slopes. Only half of the 51 farms in existence in have survived. Animal husbandry has become unprofitable due to lack of demand and low product prices, which has resulted in an increasing number of fallow meadows and pastures.
This can be surmised to be the leading cause of new plant growth in the region.
