Calculation of nutritional value
Hi. I am currently trying to manually calculate the nutritional value/info for one product. For example my product contains 2 ingredients with different nutritional info. May I know how I can calculate the product's nutritional value based on the nutritional info from the 2 ingredients manually? I do know the easiest way is to send in samples to the laboratory but I would like to how it is being calculated as I would like to able to crosscheck that the nutritional value for end product is correct. Example:
First ingredient (only 70% of it is used in the product):
Energy (kJ) = 3552
Energy (kcal) = 864
Fat = 96
Carbohydrate = 0
Protein (Nx6.25) = 0
Salt (sodium x 2.5) = 10
Second ingredient (only 30% of it is used in the product):
Energy (kJ) = 1480
Energy (kcal) = 353
Fat = 1
Carbohydrate = 85
Protein (Nx6.25) = 1
Salt (sodium x 2.5) = 0.5
Finished product:
Energy (kJ) = 1995
Energy (kcal) = 477
Fat = 46
Carbohydrate = 1
Protein (Nx6.25) = 0.5
Salt (sodium x 2.5) = 9
Would appreciate if anyone can assist me on this with a thorough calculation. Thank you in advance.
Hi naderk,
Calculating based on your ingredients is absolutaly possible.
That means you are using the following:
(Value A * 70%) + (Value B * 30%)
(3552*70%)+(1480*30%) = 2930,4 = 2930
(864*70%)+(353*30%) =710,7 = 711
(94*70%)+ (1*30%) = 66,1 =66
(0*70%)+ (85*30%) = 25,5 =26
(0*70%)+ (1*30%) = 0,3
(10*70%)+ (0,5*30%) = 7,15
Finished product:
Energy (kJ) = 2930
Energy (kcal) = 711
Fat = 66
Carbohydrate = 26
Protein (Nx6.25) = 0.3
Salt (sodium x 2.5) = 7,15
You can make easy excel forms for this if math is not your strong suit.
Good luck!
