From a young age I knew that I loved culinary, I think it was seeing the joy on everyone’s faces during family gatherings. I thought it was my destiny to become a restaurant chef but after high school I decided to take my college education down a more scientific path. During my undergraduate studies I learned about food from a new interesting perspective; science, technology, sustainability and safety.
I must admit that I had no idea one could become a professional food scientist. Normal people don’t realize what a major role in the development of food products we play in the global market. The plethora of disciplines in the food industry is vast and fascinating! Common products that you purchase each day have been researched, designed and scrutinized by a team of food industry professionals.
As a Food Scientist we make sure that what you purchase is consistent in quality and most importantly, safe to eat! I want to share with you my journey of becoming a food scientist, and my experience on obtaining my Certified Food Scientist credentials through the Institute of Food Technologists (IFT).
What is Food Science?
Food science is the study of the physical, biological, and chemical makeup of food. It draws from many disciplines in an attempt to better understand food processes and ultimately improve food products for the general public. Food technology applies food science principles for the selection, preservation, processing, packaging, distribution, and use of safe food.
Food Science Disciplines:
Food chemistry – the molecular composition of food and the involvement of these molecules in chemical reactions
Food engineering – the industrial processes used to manufacture food
Food microbiology – the positive and negative interactions between micro-organisms and foods
Food packaging – the study of how packaging is used to preserve food after it has been processed and contain it through distribution
Food preservation – the causes and prevention of quality degradation
Food safety – the causes, prevention and communication dealing food-borne illness
Food technology – the technological aspects
New product development – the invention of new food products
Sensory analysis – the study of how consumers’ senses perceive food
What is a Food Scientist?
A Food Scientist uses science and engineering skills to research and develop food products and ensure the safety of our food supply. By applying their findings, they are responsible for developing safe and nutritious foods, while incorporating innovative packaging that line the supermarket shelves.
Food products that are available in the market are the result of extensive food research; a systematic investigation into a variety of food properties and compositions. After the initial stages of research and development comes the mass production of food products using principles of food technology. All of these interrelated fields contribute to the food industry – the largest manufacturing industry in the United States.
Becoming a Food Scientist:
There are numerous universities that offer food science degrees in the United States and internationally. There are many resources online to find schools and details on their program offerings. I recommend you request information and tour the school campuses if you can. If you know someone in the food science industry, then pick their brain and find out what schools they recommend. The IFT knowledge center is also a great resource for information on food science programs.
Here is my education path:
- California Polytechnic University, San Luis Obispo, CA- Bachelor of Science, Food Science and Nutrition
- California Polytechnic University, San Luis Obispo, CA- Master of Science, Agriculture Specialization in Dairy Products Technology- Dairy Products Technology Center
- The Art Institute of California, Orange County, CA- Associate of Science, Culinary Arts
Becoming a “Certified” Food Scientist:
The Institute of Food Technologists (IFT) is an international, non-profit professional organization for the advancement of food science and technology, and is the largest food science organization in the world. For over 70 years, IFT has strived to “feed the minds that feed the world”, growing a food science based community and global forum to connect, share and learn. IFT is a visionary organization actively advocating and ensuring safe and abundant food supply for people around the world.
In 2012, The Institute of Food Technologists announced they would be offering a Certified Food Scientist (CFS) credential. Through this program, the food science profession provided a formal certification program to recognize the applied scientific knowledge and skills of food scientists.
CFS is a globally recognized certification program designed to meet the International Standards Organization (ISO) 17024 standard for personnel certification programs, and is a way for food scientists to demonstrate their expertise and commitment to the profession. The International Food Science Certification Commission (IFSCC) was established to oversee the governance and policy-making for credentialing activities.
To obtain and maintain a food science credential, you need the following:
- Meet the eligibility based on degree(s) earned and work experience in food science (see chart below).
- Complete the application ($550-750 fee to take the exam)
- Take the CFS examination (Computer based exam, 120 questions)- Results available in approximately 6 weeks from the last day of the exam testing window.
- Maintain your certification- A recertification cycle occurs 5 years from the date of certification and completion of 75 contact hours over 5 year ($300-425).
Certified Food Scientist Eligibility:
In order to become a Certified Food Scientist, you must first meet the minimum requirements before taking the exam:

Now if you have met the requirements, it’s time to prepare for the exam!
Certified Food Science Exam Prep:
IFT provides a Certified Food Scientist Candidate Handbook, which is meant to guide you during your study preparations for the test. It contains detailed information on the exam content outline, testing windows and exam delivery information.
I personally felt that the content was very broad, especially if your career path has been more specialized and focused. However, the test is meant to cover the basic breadth of food science and current laws and regulations, specifically testing the applied scientific knowledge and skills of food scientists. You may not be an expert in each area, however in your career you have likely had exposure and experiences, therefore your basic understanding and awareness is what is important.
The certified food scientist candidate handbook provides the following competency areas on the Exam and percentage of questions asked in these areas:
- Product development (34%)
- Quality Assurance and Control (17%)
- Food Chemistry and Food Analysis (10%)
- Regulatory (10%)
- Food Microbiology (9%)
- Food Safety (9%)
- Food Engineering (6%)
- Sensory Evaluation & Consumer Testing (5%)
During my test preparation I took the following steps:
1) Attended the Certified Food Scientist Preparatory Course, offered by IFT- This course was designed to review each competency area in the certified food scientist candidate handbook. This is accomplished with excellent expert lecturers, printed lectures, practice questions, quizzes, follow up webinars and review sessions. The course lasted 1 1/2 days and 5 weekly webcasts with a cost of $630-845.
During the course, you are able to gain valuable perspectives from other industry professionals. A nice perk is the access to numerous practice questions modeled after the content in the exam. This helped to get a feel for how questions were structured, an advantage if you are willing to pay the cost. I would highly recommend this course to CFS candidates, as it will definitely refresh your knowledge and streamline your studying.
Wondering if you should take the course? The prep course is recommended but is not essential for you to pass. For being the first class to ever take the CFS exam I thought the course was very helpful in passing.
2) I created a study guide- I used the certified food science handbook as a study guide outline, and conducted more research on sections that I did not have as strong competency. I also heavily reviewed the lecture information I received from the CFS preparatory course.
3) Note Cards- For some of the detailed information and concepts, I created note cards to review and quiz myself. I used this method throughout my education, however it is laborious so it may not be for everyone. I just tend to remember small chunks of information best if I break them down.
4) Websites and Books- The USDA, FDA, Code of Federal Regulations and WHO Codex Alimentarius government websites are great resources to find food safety and current laws and regulations on food. I did not buy any of the books on the recommended resource list because I had many similar books from college. However if you would like to purchase some reference materials, I would recommend:
- Food Science: Fifth Edition
- Food Safety for the 21st Century
- Food Processing Technology
- Sensory Evaluation Techniques
5) I gave myself at least 3 months to study and prepare for the exam- Attending the CFS preparatory course was a great way to kick start the studying. Luckily the exam was offered between 2-3 months after the course. I created a workable schedule, and made a point to study at least 2 hours each night during the week, and longer hours on the weekend. It was certainly a challenging time, reminding me of those late night cram sessions in college! If you are not taking the CFS preparatory course, you may want to give yourself a few extra months to study.
Taking the CFS Exam:
The exam is offered three times per year and may be taken within approximately a 3 week testing window. The exam is a 3 hour computer based test, administered at Pearson Professional Centers.
- 120 multiple choice questions (100 that will be scored, the remaining to be used in possible future exams).
- You are given an erasable note board or small notebook to use. There is also a scientific calculator available on the computer.
- You can add comments for each question, providing additional justification if needed for your answers for the exam reviewers. I recommend not spending too much time with comments, answer all of the questions you can with confidence first.
- You can electronically mark any questions you are unsure about, go back, and review at the end of the exam before you submit your answers. This helps to pinpoint exactly what questions need more thought.
Benefits of Food Scientist Certification:
The Institute of Food Technologists highlights the numerous benefits of the CFS certification. The CFS examination focuses on the practical applied knowledge that food scientists need to be competent professionals. The exam was developed by evaluating the global practice of food science and is firmly grounded in the established fundamental knowledge and skills food scientists apply in all aspects of their jobs. The purpose of the CFS certification is to:
- Demonstrate the professions’ commitment to safe and quality foods for consumers
- Reinforce IFT’s commitment to ensuring a strong talent pipeline to meet the scientific needs of the food science & technology community
- Promote lifelong learning that complements both academic learning and work experience
