I would like to know the nutrition content of a certain food (i.e. total calories, fat, protein, carbohydrate, etc.). I know there are resources in the internet that can help you find out if you know the ingredients, but let's say I don't have the recipe to make this food. Thus, I am thinking of asking a lab to analyze the food. How much money should I be preparing for this typically, and what do these labs usually need (e.g. food samples, etc.)? Note: I am in Singapore.
