In the previous question you indicated that you think that Folch extraction was used to determine total fat in biscuits. Why do you think so?

Title of page

You are not right. It is not likely that the Folch method was used. Although it is true that the Folch method releases fats from lipoproteins and liposaccharides, and therefore can be used to extract both structural and storage fat, the Folch method will not extract all fats when fats are occluded in the food matrix due to baking or cooking procedures, as is the case in biscuits. So most likely the laboratory did not use the Folch method.

Right, you are true that it is not likely that the laboratory used the Folch method. But not because it is not necessary to extract phospholipids and glycolipids. The Folch methods is not suitable because biscuits contain fats that are occluded in the food matrix, due to the baking procedures. The Folch method is not able to extract those occluded fats completely.

I do not longer think that this method was used because it is not necessary to it is not necessary to extract phospholipids and glycolipids.

I do not longer think that this method was used because the Folch method provides incomplete extraction of occluded fats.
