A list of 16 quality and safety attributes of milk products based on previous studies was compiled and used in this study. The balanced incomplete block design technique was used to build the questionnaire administered to respondents in the data collection. The multinomial mixed logit was employed to analyze the data. Results suggest that nutritive value, shelf life, availability, purity and safety are the most important attributes of milk product; while origin, fat content, food miles, packaging and handling convenience are the least importance attributes of milk products to consumers The study concludes that demand for dairy products can be significantly stimulated in the study area when these most important attributes have been considered by producers, processors and marketers.展开更多

The healthy and balanced diet preferences of people play an important role in each human life parts. Especially milk and dairy products are necessary for human health because of their nutrition value and body functions. One of the parts of people life is university life. Starting university is a turning point in terms of eating habits, since food choices responsibility of university students increases in this period. According to the researches, increasing availability of fast foods, changes in living arrangements, life experiences, expectations, preferences and beliefs related with food selections are most common reasons regarding dietary choices in this young adults group. University students had drinking milk habits in primary school but most of them lose their habits during university life. The students' first preferences were cheese and then yogurt and finally milk. A very little part of university students consume milk and dairy products regularly. The consumption habits and milk and dairy product catering of university students were examined. The consumption preferences of milk and dairy products of the students in different Universities are reviewed in this review.展开更多
