Private brands are representing an important vector for retailers, helping them to build sustainable relationships with their customers. Usually, private brands are perceived as products differentiated by lower prices. The purpose of this research is to identify consumers' trust level in private brands used in food retail and their perceptions about the quality of retailers' own products. The research question is: What are consumers' perceptions about using private brands in food retail? Pursuing this question, a survey based on a questionnaire was carried out. Research findings showed that the main reason why people buy private brands' products is lower price rather than high quality. The interviews showed that the typical private brand user is male, aged between 45 and 65 years old, with middle-level income, and employees with secondary education. These results are useful for retailers in their efforts to decide strategies for their private brands and for building consumers' trust. The findings are useful for food producers as well, because they should reconsider their marketing strategies in order to adapt themselves to the continuous growth of retailers' private brands.

The sustainable food consumption topic is a comprehensive one, including under its research area several perspectives, from the individual onesconsidering health benefits, income restrictions or educational factors, to collective perspectivesconsidering availability of sustainable food, marketing strategies or even national and international policies in favour of sustainable food consumption. In this case, it is obvious that research does not stand on the sole ground of consuming ecological products, but it has many more anchors and strings, so it should be a topic of interest for many researchers. In this case, this paper presents a bibliometric analysis of the sustainable food consumption topic as it appears in all the abstracts on Web of Science data base and a word network mapping of the main themes and sub-themes mostly used by the researchers in this area of knowledge, with the help of the Vosviewer software.

Romanian agrifood sector has experienced a profound paradigm change during the last period, especially after the accession to the European Union (EU). Starting from the need to be convergent to the EU agricultural model requirements and valuing the domestic agricultural potential, numerous developments and constraints have occurred. The objective of the study is to further examine the competitiveness constraints of Romanian wine sector. The study reveals that the wine production has suffered a dramatic improvement both on quantity and quality. The paradigm change imposed by replacement of the hybrid vines with noble vines has triggered both a quality and competitiveness increase. The domestic wine producers have adapted their production to the new market demands. Now they must fulfill both the national and European competitiveness constraints and they should stay as a new quality wine promoter.
