Yes, the data show gram Fatty Acid Methyl Ester (FAME) per 100g FAME this is the same as g Fatty Acid per 100gram margarine because

No, these data represent g FAME per 100g FAME, this is not the same as g FA per 100 gram margarine because

Not right. g FAME per 100 g FAME is only equivalent to gram fatty acids per 100 g product when the food contains only fatty acids and no other fats or non-fat components. This is usually not the case for foods. Although the percentage of fatty acids in margarine is high, margarine contains also other fat and some non-fat components.

Not completely right. Fat in margarine consists mainly of triglycerides. Triglycerides not only consist of fatty acids but also of glycerol. Therefore g FAME per 100 g FAME is not equal to g fatty acids per 100 g margarine.

Not completely right. Although the percentage of fatty acids in margarine is high, margarine contains also other fat and some non-fat components. Therefore g FAME per 100 g FAME is not equal to g fatty acids per 100 g margarine.

Right! So there are some calculations needed to convert gFAME per 100gFAME to gram fatty acids per 100g margarine. In the next questions you will do these calculations.

|  | 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) : Total trans fatty acids (g/100g) : Total n-3 FA (g/100g) : Total n-6 FA (g/100g): |  |

You will start with calculating total saturated fatty acids (SFA) in gram per 100 gram margarine. Can you simply summarize all values for SFA (see excel sheet) to get total SFA in gram per 100 gram?

In margarine total fat consist only of fatty acids.

Margarine contains only fats and no other components.

In margarine total fat consists only of triglycerides

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.
