Determination of energy value of food
Many governments require food manufacturers to label the energy content of their products, to help consumers control their energy intake. To facilitate evaluation by consumers, food energy values (and other nutritional properties) in package labels or tables are often quoted for convenient amounts of the food, rather than per gram or kilogram; such as in "calories per serving" or "kcal pe… WebReal estate acquisitions & development professional with 15+ years of value creation in property and special situations investment, across main asset classes and niche property sectors inclusive ...
