Today, most skim milk is created by spinning whole milk in a centrifuge so that the fat droplets separate out. [6] To make low fat milk, one can simply mix skim and whole milk in a fixed ratio. [7] Higher-fat milk can be created by mixing whole milk with cream, as in half and half. [8]
The rate at which the consumer encounters food items per unit of food density is called the attack rate, a. The average time spent on processing a food item is called the handling time, h . Similar equations are the Monod equation for the growth of microorganisms and the Michaelis–Menten equation for the rate of enzymatic reactions.
A system may be targeted at a specific audience. Rating systems have been developed by governments, non-profit organizations, private institutions, and companies. Common methods include point systems to rank (or rate) foods based on general nutritional value or ratings for specific food attributes, such as cholesterol content. Graphics and ...
Nutri-Score label (A) for the highest nutritional quality. The Nutri-Score, also known as the 5-Colour Nutrition label or 5-CNL, is a five-colour nutrition label and nutritional rating system [1] and an attempt to simplify the nutritional rating system demonstrating the overall nutritional value of food products.
The Monod equation is a mathematical model for the growth of microorganisms. It is named for Jacques Monod (1910–1976, a French biochemist, Nobel Prize in Physiology or Medicine in 1965), who proposed using an equation of this form to relate microbial growth rates in an aqueous environment to the concentration of a limiting nutrient.
The Insulin Index is not the same as a glycemic index (GI), which is based exclusively on the digestible carbohydrate content of food, and represents a comparison of foods in amounts with equal digestible carbohydrate content (typically 50 g). The insulin index compares foods in amounts with equal overall caloric content (240 kcal or 1000 kJ).
Water content of dairy products is quite variable. Butter is 15% water. Cow's milk ranges between 88 and 86% water. Swiss cheese is 37% percent water. [3] The water content of milk and dairy products varies with the percentage of butterfat so that whole milk has the lowest percentage of water and skimmed milk has the highest.
In chemistry, the mass fraction of a substance within a mixture is the ratio (alternatively denoted ) of the mass of that substance to the total mass of the mixture. [1] Expressed as a formula, the mass fraction is:
