Research applications of osmotic dehydration to food processing in technology and in component transfer mechanisms are being carried out in several countries. Osmotic dehydration is a traditional process applied to food dewatering. It leads to attractive products that are ready to eat or can be applied as a pretreatment to the next process such as drying or freezing. The new osmotically dehydrated products and industrial applications require appropriate manufacturing procedures at the industrial level. Thus, an understanding of factors affecting mass transfer during osmotic dehydration is required for the process optimisation. In this review, the mechanism of osmotic dehydration is described. In addition, some factors that affect on mass transfer during osmotic dehydration such as types of osmotic agent, concentrations of osmotic agent, processing temperatures, agitation or stirring process, pretreatment methods and edible coating were reviewed.

Factors affecting mass transfer during osmotic dehydration of fruits.

Wetlands are very vulnerable ecosystems and sensitive to changes in the ground water table. For the last few thousand years, hydrological balance has also been influenced by human activity. To improve their cropping features, drainage activity and fertilizing were applied. The drainage process led to an abrupt change of environment, the replacement of plant communities and the entire ecosystem. The problem of carbon sequestration is very important nowadays. A higher accumulation rate is related to higher carbon accumulation, but the intensity of carbon sequestration depends on the type of mire, habitat, and climatic zone. The main aim of this article was an examination of the changes in poor-fen ecosystem during the last 200 years in relation to natural and anthropogenic factors, using paleoecological methods (pollen and macrofossils). The second aim was a detailed investigation of the sedimentary record to aid our understanding of carbon sequestration in the poor fen of temperate zone. This case study sh...

Intersectoral and intermunicipal cooperation are still underdeveloped spheres of public and economic development policies This also applies to the natural economy to a large extent Scientific discussions are invariably focused on pro-competitive activities, the economic efficiency of which is not always sufficient In this paper the authors attempt to identify factors leading to cooperation between local government authorities and economic entities focusing on the forestry and wood-based sector in Poland These processes were analyzed within the framework of the Spatial Economics and New Institutional Economy, both in the theoretical and practical context The aim of the research was to identify the ability to create intersectoral and intermunicipal partnerships in already existing and newly established functional areas, as this may determine the development of the forestry and wood-based industry

Intersectoral and Intermunicipal Cooperation as a Tool for Supporting Local Economic Development: Prospects for the Forest and Wood-Based Sector in Poland

Atlas of the forest sector in Poland

Forestry and the wood-based sector, including the wood industry, which is an important element of economic systems and a source of budget revenues for many countries in the world, found itself in the first quarter of 2020 in a situation of a serious threat of a prolonged crisis as a consequence of the pandemic. In this perspective, it is necessary to review existing sector strategies and look for new solutions to ensure first survival, then functioning and finally development of entities forming the wood market. In the scientific research, which is the subject of this work, an attempt was made to multi-criteria analysis of the selection of the optimal anti-crisis strategy for actors from forestry and the wood-based sector in the face of a pandemic. Preparatory studies were conducted on the example of Poland, where both forestry and the wood industry belong to the dominant sectors of the economy, conducting them at the turn of March and April 2020. The research was referred to the primary wood raw material market in Poland, which is the main link in the value chain, created first by the dominant owner: Państwowe Gospodarstwo Leśne “Lasy Państwowe” the “State Forests” National Forest Holding (SFNFH), and then forest service entrepreneurs, to entities representing the wood industry. The work uses a concept modified for the purposes of the author's research scenario, based on the method of multi-criteria hierarchical analysis AHP (Analytic Hierarchy Process). The best possible decision was to be searched that would allow the selection of the optimal anti-crisis strategy for enterprises actors of the sector concerned. Based on the collected results and their expert discussion, recommendations for sectoral policy for forestry and the wood-based sector were then formulated. The proposed solutions are located against the background of a dispute between the concept of institutional intervention and a model taking into account the effects of market factors. The work is both cognitive (optimization and adaptation of the research method) and practical up-to-date. An accurate development strategy for forestry and the wood-based sector is urgently needed and necessary to implement as quickly as possible.
