Preface

According to the long-term plan accepted by the Editorial Board, at the end of December 2013 we present to our readers the 37th issue of the Polish Journal of Commodity Science. Continuing efforts to widen the group of our readers we present some papers in English version. As before, regardless the language of the original publication, each paper contains a wide summary in both Polish and English. The summaries of all the works published one can find on our webpage http://www.tpj.uniwersytetradom.pl. The series of 16 articles in the current issue of our magazine begins with the work by Skawinska on analysis of the barriers to the progress of the transfer units on the example of companies from Wielkopolska. The author highlights the diverse activities in the development of innovation in technology transfer units and different future barriers to developement. The following three types of units with a specific role in the growth of innovative region: entrepreneurial, conservative and defensive were introduced in the paper. Limited information about innovations in the market, imperfection of innovation measures applied and scope of the proposed improvements were discussed. In the consecutive work Pamfilie et al. discussed the innovation activity of Romanian companies. It was found that the companies with the highest number of inventions combined their innovation activity mainly with the establishment of partnerships, with the implementation of inside-in and inside-out processes, research centers within universities, investing in start-ups. Although the use of open innovation in Romania is at an early stage of development there is a strong correlation between the innovation activity of Romanian companies and the results achieved in relation to the competitors. Jastrzębska paid attention to nanofillers and their influence on the properties of composites with high content of polyester and glass waste. The study showed that Polish modified bentonites improved the performance of polyester composites with polyester-glass waste. It was observed that the addition of nanofillers tested increased the strength parameters and the reduced water absorption by polyester composites. In the next paper Kafel discusses the issue of protection against unfair practices. The author analyzed the texts of the specifications registered by the European Commission for Polish traditional and regional products with respect to the provisions concerning the labeling of these products. The study was supposed to determine the extent to which the requirements set out by the manufacturers associations help to guarantee the authenticity and recognition of the products on the market. It was found that the benefits of the regulation of labeling in specifications of traditional and regional products were not fully utilized by the Polish associations registering such products. It is believed that the implementation of the quality management system according to ISO 9001 makes it possible to improve the organization at all levels. Zimon and Sikora conducted surveys to determine the conditions affecting the decision on implementation a quality management system in small and medium-sized organizations. The research shows that the management of small and medium-sized construction and commercial organizations puts much attention to improving the image of the company and the quality of customer service and hopes that comply with the requirements of ISO 9001 will allow them to improve the functioning of their organizations. In the next article Ozkan discusses the problem guarantying the quality and prices of agricultural products in Turkey by identifying the factors that determine the size of their reserves. Author considered the effect of the sale form (timely and premature) of agricultural products on maintaining the size of reserves of these products. The quality of manuka honeys available on the Polish market is the subject of Wilczyńska experiments. The author identified the organoleptic characteristics and selected physico- -chemical parameters of commercial honeys and compared them with the requirements set out by the Polish legal regulations. It was found that manuka honey quality was satisfactory. The physical and chemical parameters of these honeys in most cases fall within the guidelines for the Polish varietal honeys. The strategy of democratic values as a tool to promote sustainable development and the creation of green jobs are the subject of interest of Matarazzo et al. The authors treat the strategy of democratic values as a new tool which should guarantee not only the rational management of human resources, but also a high quality of human capital and profits for companies and organizations that focus on training and motivating their teams of employees. Ice creams belong to the group of products exhibiting a high seasonality. Their producers take a lot of marketing and organizational measures to reduce the seasonality. A study of consumer preferences, which is the subject of the article by Palki, can be an example of such action. Based on the survey author suggests that the ice cream market in Poland still has a lot of potential, as the consumers in addition to traditional flavors also show interest in completely new ones. Production waste pose a threat to the natural environment. On the other hand, they can often provide a valuable raw material. In the consecutive work Rypińska and Biegańska discuss the possibility of using industrial waste of vegetable origin. The authors discuss the quality and environmental aspects of the use of wood, fruit and vegetable wastes. They suggest that the latter may be a convenient raw material for the production of natural dyes. In the next paper Swat and Zielinski present the results of research concerning the evaluation of antiradical activity of several fruit juices on the Wielkopolska market. It was found that in most cases higher antiradical activity corresponded to a higher content of phenolic compounds in the juices examined. Evaluation of the antioxidant activity of food products is the subject of research by Sielicki and Małecka. The authors tested rosemary extract in linseed and cold-pressed rapeseed oils. It was found that the oxidative processes in linseed and rapeseed oils run in a different way. In relation to oils tested, the 0.1% rosemary extract showed higher antioxidant activity than the 0. 02% synthetic antioxidant BHT. Evaluation of antioxidant plant products is the subject of the Newerli-Guz research. The author investigated the antioxidant properties of the herbes de Provence. The herbal mixture consists of thyme, rosemary, and other leafy herbs. It was found that apart of seasoning, the herbes de Provence exhibited strong antioxidant properties. The last three works relate to the issue of raw materials and quality of cosmetics. In the first one Cieszyńska discusses essential oils as ingredients in cosmetic products. This paper provides an overview of the literature on essential oils and their antioxidant, antibacterial and antifungal activities. These properties allow the potential use of essential oils as a preservative and antioxidant substances in cosmetic formulations. In the next article Wybieralska and Jeńć present the results of research on the possibility of using plant extracts from blueberry, tangerine, pomegranate and young green wheat as preservatives in cosmetics. The authors investigated the stability of cosmetic creams infected with Candida albicans, Pseudomonas aeruginosa and Staphylococcus aureus. It was found that the juice of tangerine and pomegranate added to cosmetic creams inhibited the growth of these microorganisms. The subject of the last article by Janiszewska and Dawidziuk is the possibility of application of macerate carrot in sunless tanning cosmetics. It was observed that the lotion containing the carrot macerate significantly improved the condition of the skin and its hydration. It was found that the presence of carrot macerate in sunless tanning lotions did not affect the stability of the forms of these lotions, both in accelerated aging tests and load tests. The thirty-seventh issue of our quarterly is closed by the regular column “TPJ Announcements”. It contains the report from the VIII National Symposium on “Quaternary ammonium salts and their application areas”, which was held in July 2013 in Poznan.

 I wish you a nice reading.
