Food security is one of the main concerns in the context of a global crisis such as the COVID-19 pandemic. The reduction in people’s mobility determined changes in consumers’ behavior and underlined the need for the re-organization of the food supply chains. This paper aims to summarize the effects of the COVID-19 pandemic on the global, Romanian and mountain food markets, as well as to discuss the mountain agriculture potential and the food democracy model. The trend in the post-pandemic era is heading toward the digitalization of agriculture and food distribution, with great attention on product sustainability. People are more and more aware of healthy food and the environmental impact of this sector. Many studies revealed the need for specific policies to counteract the effects of the pandemic on food quality and security and on the economic welfare of people. In the post-pandemic period in mountain areas, there is a need for the valorization of food products that originate from here since they have great health and financial potential. Supporting mountain agriculture could ensure the production of high-value products, which are generally preferred by consumers. The COVID-19 pandemic contributed to the re-orientation of consumers towards local and organic foods. Future research regarding the efficiency of the programs and policies implemented in some mountain areas after the pandemic is necessary.

Emmental or Swiss cheese is a hard, ripened cheese appreciated by consumers for its appearance and taste. This study aimed to investigate the profile of Swiss cheese consumers and producers from Ţara Dornelor area, Romania, along with the sensory analysis of the Dorna Swiss cheese produced there. For this purpose, a questionnaire was applied to 268 participants to evaluate consumer behavior. Consumers were grouped depending on consumption frequency (low—once or a few times a year, medium—once a month, and high—once a week or more), and the behavior of groups was evaluated. Producer opinion was assessed by interview and Swiss cheese sensory characteristics in two seasons were determined by sensory analysis using a semi-trained panel. The results showed that the main factors affecting consumer purchase decision are the ingredients (4.43), taste and flavor (4.41), appearance and texture (4.23), producer (3.98), nutritional value (3.88), and product history (3.67). Clustering of consumers depending on consumption frequency revealed significant differences (p < 0.05) regarding the purchase place and some factors influencing the purchase decision such as price, health benefits, and nutritional value. Producers asserted that the quality of milk is the main problem in Swiss cheese production. They consider that the raw material quality and origin, hygiene, utilities, and legislation have the greatest impact on the production process, while the trading is mainly affected by the product taste and flavor, appearance and texture, quality label, price, and product history. The sensory characteristics differed significantly (p < 0.05) between producers and seasons, with the sample produced in a stainless-steel tank and without exogenous microflora being the most appreciated in summer. These results could help producers adapt their product quality and marketing policy to consumer preferences.

This paper aimed to investigate the amino acid, fatty acid, proximate composition, total phenolic content (TPC), texture, color, and sensory properties of an Emmental type cheese from Ţara Dornelor, Romania as influenced by the processing technology (CA sample made in a stainless steel tank, with spontaneous microflora and ripening of 70 days, and TC sample made in a copper tank, with standard culture and 90 days ripening) and season (winter or summer). The results revealed that the winter samples had higher dry matter content, and were richer in some fatty acids such as palmitoleic acid, isooleic acid, 13-octadecenoic acid, and linoleic acid compared to summer. The season factor influenced significantly (p < 0.05) the amino acid profile, while the processing technology did not have a major impact. The TPC was affected by the processing technology, with the TC sample being the richest. The texture and sensory properties showed significant differences (p < 0.05) depending on the processing conditions and season. TC samples showed lower luminosity, greener, and less yellow nuance compared to CA. A reduction in the color parameters was observed in summer compared to winter. The global acceptance was correlated with the white index, the most appreciated sample obtained in summer, in a stainless steel tank.
