SIWES Logbook for Food Science and Technology: How to Fill It (With Examples)
Food Science and Technology students: how to fill your SIWES logbook, with sample entries for production, quality control and lab work.
Food Science and Technology students train in factories, bakeries, quality control labs, research institutes and regulatory agencies. The work is full of detail: processes, recipes, tests and hygiene rules. A good logbook captures that without reading like a recipe book.
Follow your school's logbook format first. This post covers what to write inside the spaces your logbook gives you.
What a good entry contains
Answer these questions each day:
- What did I do? The process, test or task.
- Which product, equipment or reagents were involved?
- How was it done? The main steps, in order.
- What did I observe or measure? pH, moisture, temperature, weight, sensory results.
- What did I learn? One clear lesson.
- Hygiene or safety: GMP, PPE, sanitation or HACCP points, if relevant.
Three to six lines is enough.
Weak entry versus strong entry
Weak:
Today I worked in the production area and learned how food is made.
Strong:
Today I assisted in the production of biscuits. I weighed flour, sugar and fat according to the recipe, helped to mix the dough, and monitored the oven temperature during baking. I learned that small changes in baking time affect the colour and texture of the final product.
Sample entries by area (fictional, for style only)
Production
I helped on the bread production line. I weighed the ingredients, mixed the dough, moulded the loaves and loaded them into the oven. I recorded the baking temperature and time. I learned the importance of proofing time for bread volume.
Quality control laboratory
I assisted the QC analyst in determining the moisture content of a flour sample using the oven-drying method. I weighed the sample into a crucible, dried it in the oven and reweighed it after cooling in a desiccator. I calculated the moisture content from the weight loss. I learned why moisture control matters for shelf life.
I measured the pH of three juice samples using a calibrated pH meter. I rinsed the electrode between samples and recorded the readings. I learned the need to calibrate the meter with buffer solutions before use.
Microbiology and food safety
I helped to prepare nutrient agar and plated diluted samples of a ready-to-drink product for total plate count. I observed aseptic technique and labelled the plates. I learned why sterile technique is important in food testing.
Packaging and storage
I assisted in checking the seal integrity and labelling of packed products. I compared the batch codes and expiry dates with the production record. I learned how traceability supports food safety.
Hygiene and GMP
I attended a briefing on good manufacturing practice and the company's HACCP plan. I learned about handwashing, protective clothing and cleaning schedules in the production area.
Product development
I helped to prepare trial samples of a new snack with different levels of salt. Panellists scored taste and texture on a hedonic scale, and I tabulated the scores. I learned the basics of sensory evaluation.
Weekly summary sample
This week I worked in the quality control laboratory. I learned to determine moisture content and pH, prepared culture media and took part in sensory evaluation. I learned that quality is checked at each stage of production, not only at the end.
Tips specific to Food Science and Technology
- Name the product and the test. "Moisture content of flour" is better than "did analysis".
- Include readings only if you took them. pH, temperature, time and weights.
- Show hygiene awareness. One line on GMP or PPE shows you understand the field.
- Link to your courses. Food chemistry, food microbiology, processing and quality control give your entries depth.
- Respect confidentiality. Do not write secret recipes, formulas or supplier prices. Describe the process in general terms.
- Keep a small notebook to jot tasks during the day, then write the entry in the evening.
If the week was slow
Describe what you observed, any small tasks you did and what you learned. See what to write in the logbook when no work was done.
Getting signatures
Show your supervisor your entries weekly. See how to fill your SIWES logbook properly.
Drafting entries faster
Tell the MonoEd SIWES Logbook your course, company and tasks and it drafts weekly entries in the right style. You still copy them into your official logbook by hand and get your supervisor to sign.
At the end, the MonoEd SIWES Report Generator drafts your report from your notes. See the Food Science and Technology SIWES report guide. Food companies, research institutes such as FIIRO and regulators such as NAFDAC and SON are worth contacting for placement. The Biochemistry placement guide shows the kind of laboratories to look at.
Frequently Asked Questions (FAQs)
How do I fill a Food Science and Technology SIWES logbook?
Write one short entry a day naming the process or test, the equipment, the steps and what you learned. End each week with a summary and get it signed.
Can I include recipes?
Describe the process in general terms. Don't write secret formulas or recipes.
What if I only worked in packaging?
Describe what you did, such as checking seals, labels and batch codes, and what you learned about food safety and traceability.
What should I say about hygiene?
Mention GMP, PPE, handwashing and cleaning schedules where they apply.
What if the factory has little equipment?
Describe the tasks you did and what you learned. Be honest and specific.
Who signs it?
Your industry-based supervisor signs weekly, and your school supervisor signs when they visit.
