The Beet Root Lab Report
For Tuesday/Understanding we’re solving the mystery of the beet root that wasn’t. The first step in this mystery is analyzing the lab report (attached below). Open the PDF report and take a look. There are three important things you need to be able to find on any report from a science lab (often called a Certificate of Analysis or COA):
- The method: how did the lab analyze the material?
- The results: what data came out of the test?
- The conclusion: based on the data, what conclusion did the lab make about the material?
See if you can find all three of these on the report. In a reply to this post, list a short description of what you think the method, results, and conclusion are on this report. We’ll break down each of these in detail on later posts.

So right off the bat, the method of testing is at the top of the document, the results are around the middle and the conclusion is at the bottom. The conclusion is that the tests showed that the 100% beetroot powder was in fact not 100% beetroot power, instead containing Polyethylene Glycol.

1. The method: they took a sample of organic beetroot that they knew was pure and compared that to the other sample
2. The results: There is Polyethylene Glycol in the samples
3. The conclusion: they weren’t the same so they did not accept the new beet that was coming in

You both got 2/3 answers:
- Method: High Performance Thin-Layer Chromatography with Photo-Documentation
- Results: the photo of the “lanes of material” and description of the lane materials. Polyethylene Glycol is not a contaminant, its part of the testing materials.
- Conclusion: “This test sample Organic Beet Root Powder_Vendor:A&Y Nutrition (RM023.010423) is not characteristic of Beta vulgaris root.”
