The mineral contents were calculated for a certain grains in their raw form. How can we calculate how much a given mineral, say; zinc or iron can be served by a portion of the flour sample per 100 g flour in comparison to recommended daily intake of the minerals of interest? Most importantly, does it give sense to report such information for raw food sample?
Dear Abera,
First I will start with your last question; Yes, it is important to reoprt on the nutrient or micro-nutrient content of a raw food sample especially if the sample is a non common sample with unknown composition and try to understant it nutritional value supply in the human system if it is an edible stuff is also very important.
Now, for the first question, I think you need to recall that the mineral (Zn or Fe) you determined has a unit (may be in PPM for example) and this you have evaluated in a given weight of sample, let's say 2g of sample , then you will need to convert your mineral concentration into grams and make it correspond to the 2g of sample evaluated. Thereafter, by simple cross multiplication you can convert it in gram per 100g of sample.
I think this may help
Regards!
Dear Dr. Harouna,
Thank you so much for your informative explanation.
Kind regards,
