My advice would be that a Masters degree is like a roller coaster. You will have your ups and downs in your research but that is all apart of being a scientist! There is no such thing as a 'bad' discovery.
Try your best to reach out to faculty and make connections with people who share the same passions as you. Everyone at the University of Guelph is happy to share their expertise and provide guidance, and those connections are very valuable in expanding your knowledge and reaching your goals.
The faculty profiles page, on the Food Science Department website, is very useful to help find research projects that you may be interested in. Do not hesitate to email or talk directly to the faculty members. They are always welcoming, and can even help you apply for scholarship funding!
Get involved in the community. Grad school is more than your research project; expand your contributions beyond your field of research and into the community where you are working.
