Please note that:

- it is common practice to classify all fatty acids with at least one bound with a trans configuration (also if there are one or more bounds with a cis configuration) as trans fatty acid.

- for this margarine analysis all fatty acids for which the configuration is not mentioned in the laboratory output are cis fatty acids.

|  | This is the information you would like to include in your database: Total fat (g/100g): Total PUFA (g/100g) : Total MUFA (g/100g) : Total SFA (g/100g) : 29.8 Total trans fatty acids (g/100g) : Total n-3 FA (g/100g) : Total n-6 FA (g/100g): |  |

Question Text

Please add the result for total trans fatty acids to the table above.

Correct!

Hints:

1) Summarize in the excel sheet all Trans fatty acids.

2) Multiply this with F (= 0.956) to get the amount per g lipids.

3) Multiply this with 0.80 (the fat fraction in margarine). This will give you the final amount of trans fatty acids in g per 100 g margarine. Add this answer to the table.

Your answer is still incorrect. Please try again, and if possible ask your supervisor for help. If you do not succeed to find the right answers, please click submit again to get the right answers.

Now the right answer is shown, so you can continue with the case.

Also calculate total trans fatty acids and add the result for total trans fatty acids to the table below.

So far you know the lab used a reliable and applicable methods to determine the fatty acid profile of the margarine. Therefore you can start with completing your database.
