This study focuses on female college students majoring in food and nutrition . There are various factors in the process of preparing for employment. Our study finds factors of empirically verifying how they affect major satisfaction and how their perceived career preparation behavior affects major satisfaction. As a result of the study, it was confirmed that career exploration, information collection, and job preparation were in the order of ranking affecting the major satisfaction of students in the Department of Food and Nutrition. Providing accurate and high-quality data to students in their career fields so that they can complete their major curriculum in food and nutrition and get a job in their major fields has the most positive impact on students' major satisfaction. However, we found that practical experience in the field did not have a major positive effect on students' major satisfaction. Students' job experiences are generally conducted in the form of practice for major companies, and during the practice period, students feel more disappointment about their major than their pride and future job hopes. Therefore, it is necessary to systematize the department's field training curriculum because it is likely to lead negative perceptions of the major in students of the Department of Food and Nutrition. It is essential to provide detailed and percise curriculum to make a prepared field practice.
