LEARNING GOALS

Course Learning Goals

At the end of the course, students will

SAFETY

• All students are expected to wear safety glasses, lab coats, gloves and hair covering during all labs.
• Wear approved safety glasses for all labs (you will not be admitted to class without them -- you each must purchase your own from bookstore, Home Depot, etc., keep track of them, and bring them to each lab).
• Lab coats and hair covers will be provided (part of your lab fee). These are required to cover your clothes and prevent contamination of foods from outside microbes. Thus, lab coats can only be worn in class. Remove whenever you leave the laboratory.
• Gloves will be provided in class when needed

HAND WASHING AND HAIR

• Disease is transferred rapidly by hand contact.
• Because everyone will share in tasting the foods prepared in each lab, students are required to wash their hands with soap and hot water at the dedicated handwashing station in the pilot plant before handling food.
• If you remove your gloves and handle clothes, back packs, etc, or leave the pilot plant during the lab, you must wash your hands again before handling food ingredients

CLOTHING

• Appropriate attire must be worn at all times.
• This means slacks (preferably, although knee-length skirts will be allowed) and closed-toe shoes.
• Sandals, shorts, skimpy tops, or other clothing deemed unsafe and unprofessional are not allowed.
• Students wearing such attire will be sent home to change, with deduction of participation points.

LAB NOTEBOOKS

• Print lab exercises and compile in a 3-ring binder.
• Bound notebooks with lab directions should be brought to each lab and used for all records; data should NOT be recorded on scraps of paper and then transferred to the notebook.
• Do not tear out pages. If errors are made, cross them out and note what the error was. Do not bring single pages of lab instructions to class.

LAB REPORT FORMAT

General Information:

• Reports are due one week after completion of laboratory. Two points are deducted for each day late. If you have a problem completing the lab for any reason, see Dr. Schaich. Reports will not be accepted beyond one week past due date unless a formal extension is granted from Dr. Schaich.
• Write reports in past tense
• DWrite in third person. Do not use personal pronouns I, We, you.
• Type reports in a PC Word file, single spaced, 1 inch margins.
• Submit reports on Canvas under ASSIGNMENTS

Report Structure: Approximately 5 page summary of laboratory and observations Include:

1. Title of laboratory
2. Student name
   Group # and Names of all other students in research group (or version of experiment performed at home)
   date lab was conducted
   date lab was due and date submitted
3. Introduction: General description of the purpose of the lab with some background on the scientific principles involved
4. Methods: General description of the methods used and what each is to accomplish. Step by step details of methods are not required. However, note any changes from conditions prescribed in lab write-up. On-line students: describe the version you tested and what adjustments were necessary for working at home.
5. Results and Discussion:
• Present key data that illustrates principles studies in the lab
• Integrate the data posted on Canvas for all 7 variations of the experiment to show how varying conditions or composition changes structures and properties of foods.
• Manipulate and present data so you can tell a story about the science involved, write a logical discussion, and present supporting evidence.
• Transform raw data to a graphical form that shows the relationships you want to discuss. Examples are shown on the next page. You may use Excel, MatLab, or any other program with which you are familiar.
• If you need help with software, contact a TA or the Rutgers computer lab. Make sure you label both axes of graphs.
• Along with graphs, describe results verbally and discuss what they mean and what they show in terms of scientific principles, whether they followed expectations, and possible reasons for discrepancies. “Other groups made mistakes” is not an acceptable explanation
• Describe the mistake and the consequences. For example: balances were not tared so weights were inaccurate. pH electrodes were not cleaned between jelly samples so calibration drifted. Make a significant effort to sort out the data and find points to demonstrate the principles being studied
• Questions at the end of each lab section are specifically focused on important issues and principles you should recognize. Answers to questions should be incorporated into the discussion of results.

Examples of how to develop graphs from raw data:





What can you learn from this data?

• Goals of exercise were to study effects of freezing rate on ice crystal size and resulting damage to products.
• We cannot measure ice crystal size but we can deduce the size from extent of damage from them based on the assumption that larger ice crystals caused more damage to cells, and hence greater release of cell liquids (drip loss).
• In addition, acids are released and tissues become exposed to air, both of which can later pigments.
• Cell damage leads to collapse of tissues after the sample is thawed.
• These effects can be seen in increased drip loss, color changes (red color fades – lightness (L) increases and red color (a) decreases), and texture deterioration (lower scores, increasing mushiness) in samples with slower freezing rates (chest freezer)
6. Conclusions: Briefly summarize what was learned from the experiment. "Data was chaos" is not an acceptable summary. Relate the key points that demonstrate scientific principles and are related to the objectives of the experiment.
7. References. List all references cited in the report. Any format may be used as long as consistency is maintained, e.g. see style guides for authors in J. Food Science, Cereal Science, J. Agric. and Food Chemistry.

Extra points will be awarded for lab reports that go beyond listed questions and course notes to integrate additional outside material relevant to the laboratory, including explanations or observations from “Good Eats” or “Food Detectives” (with appropriate citations) or from journal articles or books in the library.

To begin this process, please complete the Registration form on the ODS web site at: Rutgers Office Of Disability services Registration form.

Absence Policy

The University does recognize that temporary conditions and injuries can be problematic and may adversely affect a student’s ability to fully participate in class.

The Dean of Students Office at Rutgers University-New Brunswick provides solutions, services, and support to help students navigate Rutgers University. By focusing on students’ educational, social, and personal development, staff in the Office promote academic success and student retention. The Office serves as a student support network by providing advocacy, problem resolution, and critical incident intervention for those times when additional assistance is needed.

ACADEMIC INTEGRITY

The university's policy on Academic Integrity requires that a student:

Failure to uphold these principles of academic integrity threatens both the reputation of the University and the value of the degrees awarded to its students. Every member of the University community therefore bears a responsibility for ensuring that the highest standards of academic integrity are upheld.

Cheating and Plagiarism

(From Spring 2010 Andy Egan 01:730:252 Eating Right): "Cheating on tests or plagiarizing materials in your papers deprives you of the educational benefits of preparing these materials appropriately. It is personally dishonest to cheat on a test or to hand in a paper based on unacknowledged words or ideas that someone else originated. It is also unfair, since it gives you an undeserved advantage over your fellow students who are graded on the basis of their own work. In this class we will take cheating very seriously".

Turnitin will be used to assess students‚ submissions and all suspected cases of cheating and plagiarism will be automatically referred to the Rutgers Academic Integrity office.
