least 2 “groups” that will be compared (note: you may just have
ou have at least 1 variable esulting in at
ach of vour “eroups” – or ambitious, you can have replicates). for example, if you are fermenting some type of vegetable in salt water (e.g. kim chi) you could compare 2 different concentrations of salt, or 2 different types of vegetables. If you are making yogurt, you
could compare using 2 different types or amounts of starter culture, or, you could compare 2 different methods of cooling
down your milk+ starter culture mix, or cooling over b hours vs. L2 nours
Your report should follow the typical format of a scientific report with the following sections:
Introduction – in which you discuss the type of fermented food that you will prepare and why it interests you.
Materials and methods: provide enough details so that someone else could replicate your procedure. Results and discussion (these 2 sections are often combined): tell what happened and ADD ORIGINAL PHOTOS THAT
YOU TAKE of your product and/or the process used. Collect data (perhaps at different time points to monitor how it tastes. Try to provide as many observations as possible – note that observations are information that you take in
through your senses (or some instrument that extends your senses (taste, smell, vision, touch, hearing). If applicable, make up a scale to rate sourness / bitterness / saltiness / sweetness / alcohol content, etc. of your product. Record other types of observations: are bubbles produced? Is there a color change? A volume change? For most fermentations you could collect data /observations at different time points. Where possible, put your data into
a table or graph and provide a table or figure legend. Conclusions – briefly summarize your what you have learned from your experiment and comment on future
directions if you would try making your product again. This report should be at least 700 words (excluding a final list of literature cited. 700 words is “2 – 3 pages double. spaced. All reports should contain at least 2 photos inserted into the document (not attached along with it). Each photo
should have a figure legend (for guidelines in making a good figure legend see Ngo, 2020)
