Attended The University of Western Ontario
London, Ontario, Canada
I just thought for a start I would give you some information to work with. Although I have completed my degree in the sciences it is difficult for me to answer specifics in chemistry a field that I am aware of, but have not specialized in.
That being said I just did a quick Google search for salaries of food/flavor chemists and found this... http://education-portal.com/articles/Flavor_Chemist_Salary_Job_Description_and_Duties.html
However, you will notice on the site that there is a range in salary from about 30,000-103,000. The type of profession you choose within the field of Chemistry will make a difference in terms of your salary as well as your site of employment ie.retirement residence, hospital, laboratory etc. And the numbers I just provided you with are based off of the U.S Bureau of Labor Statistics. Thus, the location you wish to work in will also make a difference!
As you see some decisions need to be made in terms of the specifics of the profession you choose. I am sure if you major in Chemistry there will be a lot of options for you. I suggest you explore the internet for some options. A general search of some key words would be good. ie.professions in chemistry.
Hope that helps, at least a little!
