 According to the long-term plan accepted by the Editorial Board, at the end of September 2011 we present to our readers the 28th issue of the Polish Journal of Commodity Science. It was assumed that the new trends in commodity science would be the leading motive of the current issue. 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.pr.radom.pl. The series of 12 papers in this issue of the journal is opened by Urbaniak’s work on the role of so cial responsibility standards in business activity. The following tools: SA 8000, GRI, the Dow Jones Sustainability Indexes for assessing the introduction and effective implementation of the concept of corporate social responsibility, were presented. The general guidelines published by the International Organization for Standardization document contained in ISO 26000 were commented. It is suggested that application of these rules contributes to building a positive image of the company as an ethical em ployer and as an organization worthy of confidence to investors and customers. Innovativeness in companies is the subject of the article by Zalewski and Talaga. The results of re search on innovativeness in enterprises of Greater Poland in the period 2004-2006 were discussed on the bases of the information contained in the forms PNT-02. The role of different sources of information for innovative activity and forms of cooperation in the field of innovation were analyzed. The authors pay attention to the lack of cooperation between actors in the exchange of information for innovation and the presence of barriers to their application and effectiveness. On the basis of the research performed the barriers to business innovativeness were identified. The consecutive paper by Dubis deals with the problem of product quality development in compli ance with legal and normative requirements and customer's expectations. The paper discusses the legal requirements, standards and quality expectations posed by the consumer to new products. The author notes that consumers read little information published on the packaging by the manufacturer. This can lead to the conclusion that most of the information is irrelevant to the consumer, and its presence on the package in the eyes of most buyers does not affect the improvement of the quality of the product. Fur thermore, the author concludes that the multiplicity of demands posed to producers makes the process of producing new goods more and more complex and complicated. The authors of the next paper, Olbrych and Łopyta present the results of their research on assess ment of quality of health care services rendered by selected medical units. The authors conducted a survey of patient satisfaction with medical services provided in a large hospital in Radom. IPA technique was employed in the research. It was found that the technique used can help to determine which part of the service offered requires more effort, improvement, or even a complete change. In the next work, Michalak-Majewska presents the results of research on sensory assessment and consumers’ desirability of sprout seeds of selected plants. Sensory analysis was performed and the con sumers’ desirability was determined for mung bean, alfalfa, cress and radish sprouts. It was proved that the sensory quality of the sprouts is varied and depended on the species of the seeds used. Statistical analysis indicates significant differences in sensory profiles of the products. Assessment of consumer desirability showed that the most acceptable by consumers are radish sprouts, cress and mung bean. The next article by Stand and Kolman is a summary of the evaluation of the quality of selected or ange juices on the Lublin market. In this paper the quality of orange juice reconstituted from concentrate and fresh juice was assessed. On the basis of sensory evaluation and measurements of physicochemical parameters the rank of juice quality was made. It was proved that usually more expensive branded or ange juices are qualitatively better than the cheaper juices. It was found that one of the orange juices produced some hypermarket did not meet basic quality requirements. The two consecutive papers deal with the quality of cosmetic products. It has been repeatedly stated that the quality of cosmetic products often depends not only on the quality of the raw materials but also on the method of their acquisition, particularly the intermediates of plant origin. In the work by Wage mann and Zielinski's the influence of the parameters of extraction process of chamomile flowers (Chamomilla recutita) on the antiradical activity of extracts that can potentially by used in cosmetic products. The paper is a record of the findings regarding the influence of duration of the extraction of chamomile in water-alcohol systems and composition of the extrahents used on the parameters character izing the activity of antiradical extracts obtained. It was found that in the systems containing aqueous solutions of ethyl alcohol, water proved to be more effective extrahent of antiradical substances than a mixture of these extrahents. In the second work on cosmetics, Malinowska presented the results of research on market supply of skin-whitening cosmetics and cosmeceuticals in Poland 2011. The active agents and UV absorbers of skin-whitening products were examined. The physicochemical forms of the preparations offered were analzyed. The commercial products were found to contain more than 20 pure substances and several natural plant extracts having skin lightening properties, such as vitamin C, hydroxy acids, vitamin PP, octadecadienoic acid and undecylenoyl phenylalanine. The most commonly used skin whitening natural ingredients include extracts of plants such as bearberry, water lily, licorice, white mulberry and lemon. Fat oxidation processes result in many unfavorable changes of sensory features of meat products. In the next paper Szczepanik et. al. present their results on effect of rosemary extract on the inhibition of lipid oxidation in freeze-dried muscle tissue of rainbow trout during storage. On the basis of test results conducted under two various storage conditions it was concluded that the application of rosemary bath efficiently reduces the oxidation of lipids. Authors postulate that aqueous rosemary extract can be a good source of natural antioxidants for fishery products. The issue of competitiveness of enterprises in the field of packaging is the subject of work by Ucherek and Białek. The results of surveys on the determinants of competitiveness development in the field of packaging are presented. The concept of consumers’ understanding the competitiveness and innovativeness of packaging, the method of obtaining a competitive advantage, barriers to obtaining a competitive advantage in innovation, channels of transmission of information about innovations and packaging elements that attract the attention of consumers to the greatest extent were analyzed. It was shown that the biggest barriers for the packaging industry are the costs of implementation of innovative solutions, imprecisely defined regulations on the quality of packaged products entering the market and increasing competition both nationally and internationally. The authors conclude that only a unique offer can be an effective way for companies to obtain high recognition among current and potential buyers. An often defect in fabrics is the pilling phenomenon that occurs during the use of fabric as a result of wear and friction, but also maintenance of textile products. This phenomenon not only affects the appearance of the fabric but also user’s comfort. In the next article Deminowicz deals with the pilling phenomenon. This paper reviews the literature data on factors affecting pilling and methods of its as sessment. It was found that the standard evaluation methods for pilling resistance of textiles are mostly time-consuming and labor-intensive, while the results are often subjective in nature. The last work of the current issue of the journal, by Bereznenko et. al. concerns the practical appli cation of nanotechnology in the manufacture of thread. The authors studied the possibility of obtaining a bactericidal effect by the introduction to textile materials in the stage of forming the structure of the strands of synthetic nanoparticles of selected metals such as silver, copper and iron. The study also ex- amined the properties of the modified thread compound in a mixture of synthetic threads likeable. It was found that the proposed modification of silver nanoparticles and a mixture of nanoparticles of silver and copper can produce anti-microbial properties and respective strength threads. 28th issue of our quarterly is closed by the column „TPJ announcements”. It contains a report on the Days of Young Commodity Scientists that took place on the Faculty Of Commodity Science, University of Economics in Poznań.

I wish you a nice reading.
