FOOD SCIENCE AND TECHNOLOGY 101

CHOCOLATE SCIENCE

  2 Credits

3-4:36 Wednesdays

 

 

 

 

 

Chocolate Science is designed to introduce the student to the science and business behind food.  Believe it or not, there is a Department that concerns itself exclusively with food -- its safety, quality, preservation, nutrition and business.  The Department of Food Science and Technology offers majors in Food Science and Food Business Management for students interested in a career in the food industry or governmental regulatory agencies.  This course will focus on chocolate. Each session will cover an aspect of chocolate’s composition, business, safety, quality or manufacture.

 

Student Learning Objectives:

1.     To development an awareness of the breadth of chocolate flavors and textures available, while developing skills in sensory science.

2.     To recognize the complexity of the production, manufacturing and marketing of the chocolate industry.

3.     To learn team work skills by forming a virtual company and developing a chocolate product in class.

Grading:

The grading breakdown is:       

Participation                                         20%

Reading assignments                             30%

In class assignments                              20%

Final presentation of project                  30%

 

The class is graded on a straight scale: 

            A = 93-100%                    A- = 90-92%         B+ = 87-89%              B = 83-86%    

            B- = 80-82%                     C+ = 77-79%        C = 73-76%                C- = 70-72%  

            D+ = 67-69                       D = 63-66%          E = 62% or less

 

It is acceptable (and desirable) for every student to receive an “A,” if earned.

 

Participation:

Participation is graded based on attendance and participation in the project.  Attendance is expected at all classes.  In cases where attendance is not possible, a written excuse is required. Participation in the project includes working on your team’s assignments, as well as coordinating with the other teams to be sure the entire project is successfully completed.

 

Reading assignments:

Each week, one to three chapters from the book are assigned.  Approximately 10 questions will be handed out for those chapters.  The written answers to those questions are due at the start of the next class period.

 

In class assignments:

Most weeks, there will be in class writing assignments.  Those assignments are due at the end of the class period.

 

Project:

The class will form a virtual chocolate company.  The company will design, label, package, produce and market a chocolate product.  At the end of the quarter we will discuss the lessons learned during the process, and take home our chocolate product to share with our friends.

 

Academic Misconduct:

See University rule #3335-31-02.  Plagiarism and cheating are grounds for dismissal from the University.  Students are allowed to work on their lab reports together, but each student must write their own report in their own words. 

 

Statement on Disability:
If you are a student with a disability and you have been certified by the Office for Disability Services (ODS), I will gladly accommodate you so please inform me as soon as possible of your needs.  The ODS is located in 150 Pomerene Hall, 1760 Neil Ave.; telephone 292-3307, TDD 292-0901; http://www.ods.ohio-state.edu/.
