Dear all, I was experimenting on developing of hospital-made polymeric enteral formula. The formula was made of the following ingredients: milk powder, sugar, coconut oil, maltodextrin and water. What is best approach to estimate the formula osmolarity? Would that be possible to do so in absence of osmometer? Will be happy to hear any suggestions.
Basically, if you know the molecular weight of the amount of ingredients you use in the enteral formula, you can calculate the osmolality. For example, if you use 50g of glucose (molecular weight 180g) in 1L of water, you will have an osmolality of 50/180 = 0.278 Osm/L or 278 mOsm/L. For sugar, just use the molecular weight of sucrose. This should be replicable with coconut oil and maltodextrin. Milk powder may be tricky, but maybe you can check their label for details.
Mr Wong, thanks for the answer....no more work on that area now as it is a bit complicated and pose a big reliance on expensive osmometer...
