1. Sensory characterization of pu-erh tea beverages Sensory characterization of pu-erh tea beverages.pdf

Dmowski P., Karwowska K., Śmiechowska M.
The aim of this study was to develop a sensory profile of pu-erh tea beverages. Additionally, sensory evaluation results were compared with the color of the beverages measured in the CIE L*, a*, b*. The results showed that the color of infusions was a combination of black and brown with a high proportion of copper (15.00 – 63.75). The most fresh were Bio-Active and UNO-Foods. In turn, the strongest brew was prepared from Grande tea. All products were characterized by citrus flavor. Principal component analysis helped reduce the number of variables that describe presented tea, to just two. The first includes differentiators describing flavor infusion and infusion appearance, while the second cover the citrus flavor of beverages. Both groups represent 51% of the inputs.
2. German trade balance surpluses – cause or effect of macroeconomic instability in Europe? German trade balance surpluses – cause or effect of macroeconomic instability in Europe?.pdf

Feldmeier G.
In the course of the recent economic crises in various EU member countries current account balances are in the focus of political and economic debates next to discussions about public budget deficits and total national indebtedness. While the focus there is traditionally in an analysis of the causes and negative consequences of twin deficits of high public debt and negative trade balances, economies with persistent trade balance surpluses are also critically examined and blamed for being responsible for global financial and national debt crises. Thus high German trade balance surpluses are expected to be a main reason for macroeconomic imbalances within the EMU countries. However, a closer look at the target regions of German exports within this perspective modifies this assumption, also the fact that there is a strong correlation in between strong export surpluses in Germany's trade balance and positive effects for European partner countries in the form of imported intermediate input supplies from them. Another limitation of the criticism of the German trade balance surpluses results from a supply-side consideration of global export industries. According to this Germany with its remaining high share of manufacturing industry in GDP achieves traditional trade balance surpluses, whereas southern European countries with a lower share of production industry tend to be more trade balance deficit countries. These facts suggest that a politically constrained reduction of German trade surpluses and a subsequently weakening of the German economy hardly favor trade deficit countries, but would rather cause a collateral damage for global economic development.
3. The availability of fresh and frozen fish in the urban and rural areas The availability of fresh and frozen fish in the urban and rural areas.pdf

Kukułowicz A., Klawikowska M.
Eating fish is an indispensable element of a proper and well balanced diet. Despite the benefits of consuming fish, their consumption in Poland is still at a low level. At present, buying fresh fish in the urban areas is not much of a problem for consumers, because they can be purchased in fish stores, as well as in large commercial networks or at marketplaces. The aim of the study was to compare the consumers’ opinions on the availability of fresh and frozen fish in urban areas and in rural areas of Wejherowo district. The study was conducted with the use of a questionnaire survey in the group of 180 not randomly chosen people. According to respondents’ opinions on the availability of fish it appears that urban areas of Wejherowo district are characterized by high availability and a wide range of fresh and frozen fish, while rural areas have limited access to those products.
4. Assessment of knowledge of Gdynia’s citizens on the possible usage of organic foods in the prevention of health Assessment of knowledge of Gdynia’s citizens on the possible usage of organic foods in the prevention of health.pdf

Suszek-Namroży A., Platta A.
The aim of this study was to obtain information about the state of consumer awareness about organic food and its impact on health and the perception of this type of product and to determine on the basis of what factors are critical for the development of retail sales of products from organic farming system and associated with this development of organic farming. The majority of subjects had a satisfactory level of knowledge about organic products. The results indicate that the citizens of Gdynia know that organic food is characterized by high nutritional values. Centers that are efficiently informing about organic food are television and radio. Most consumers make their purchases of organic products in supermarkets and specialty stores. The majority of respondents are familiar with the EU's Euro-leaf logo, and can identify units responsible for the certification of organic food. Consumers choose organic food mainly because of concern about the health of their own and their families. Behind the main disadvantage of organic food among non-consuming subjects, was the price difference between organic products from their equivalents coming from conventional production.
5. Labelling of food products as a determinant of shopping decisions Labelling of food products as a determinant of shopping decisions.pdf

Suszek-Namroży A., Zabrocki R.
Proper labelling is an important source of information for the consumer and it is also the fulfilment of an obligation imposed on manufacturers, distributors and importers. Poland’s accession to the European Union boosted the importance of legibility of information and correct labelling in compliance with the valid regulations. The objective of this study was to examine the awareness of a contemporary consumer with respect to labelling food product packaging and the effect of encoding on product purchase. A questionnaire survey was conducted with 130 respondents (male and female). It found that a considerable portion of Polish consumers pay attention to how food product packages are labelled, particularly for dairy products, meat products and beverages. Consumers regarded the absence of information in Polish and placing illegible signs on labels as the most important packaging defects.
6. Technological and commodity science related aspects of cider production Technological and commodity science related aspects of cider production.pdf

Witt P., Śmiechowska M.
Remarkable changes in terms of alcohol consumption have taken place in Poland in the recent years. These changes refer not only to the amount of the alcohol consumed but also to the structure of the alcohol beverages. Cider is one of beverages whose production and consumption has increased remarkably. The objective of this study is to present some selected aspects of manufacturing as well as the factors determining the quality of cider. Attention has been drawn to the economic conditions of cider production in Poland. The present studies have shown that the further increase of cider production depends on the development of orchards of apple trees suitable for cider production and on the legal regulations. Reduction of excise tax on cider as a drink made of apple juice of 5% alcohol content, general community action supporting the consumption of Polish apples in 2014 as well as the change in Polish people’s preferences and choosing weaker alcohols, have caused a rise in interest among cider manufacturers and consumers.
