What is proximate analysis of food?
Proximate analysis refers to
the quantitative analysis of macromolecules in food
. A combination of different techniques, such as extraction, Kjeldahl, NIR are used to determine protein, fat, moisture, ash and carbohydrates levels.
What is the purpose of proximate analysis of food?
Proximate Analysis stands for a method, which
determines the values of the macronutrients in food samples
. In general, those values are being declared as nutritional facts shown usually on the labels of the final (end) food products, but they are also being determined during the production process.
What is proximate principle?
: compounds occurring naturally in animal and vegetable tissues and separable by analytical methods the proximate principles of food are
proteins, fats, carbohydrates, mineral salts, and water
.
Who is the father of nutrition?
The concept of metabolism, the transfer of food and oxygen into heat and water in the body, creating energy, was discovered in 1770 by
Antoine Lavoisier
, the “Father of Nutrition and Chemistry.” And in the early 1800s, the elements of carbon, nitrogen, hydrogen, and oxygen, the main components of food, were isolated …
What is proximate value?
A proximate analysis comprises the mass percentages of moisture, ash, volatile matter, and fixed carbon, which are obtained from a series of three standardized tests. From: Process Chemistry of Coal Utilization, 2020.
Is egg a protective food?
Foods that are rich in minerals and vitamins are referred to as
protective foods
. Foods such as leafy or yellow vegetables, meat, citrus fruits, egg, milk, which contain sufficient quantities of vitamins, minerals and high-quality proteins that protect against the occurrence of a disease of deficiency.

What are the components of food proximate analysis?
The proximate composition of foods includes
moisture, ash, lipid, protein and carbohydrate contents
. These food components may be of interest in the food industry for product development, quality control (QC) or regulatory purposes.
What are the reason for Analysing food?
The purpose of food analysis is
to confirm the safety and quality of food
. Within the official control of food, at the food producers, the analysis must be performed by an accredited laboratory. Accredited laboratories are also performing many other types of food analysis.
What is the importance of proximate analysis?
Proximate analysis covers
the determination of moisture, volatile matter, fixed carbon, and ash in coals and cokes
, and is used to establish the rank of coals, to show the ratio of combustible to incombustible constituents, or to provide the basis for buying/selling, and otherwise evaluating coal for various purposes.
Is the moisture content?
Moisture content is,
simply, how much water is in a product
. It influences the physical properties of a substance, including weight, density, viscosity, conductivity, and others. It is generally determined by weight loss upon drying. There are many methods for determination of moisture content.
What is the objectives of food processing?
Objectives of Food Processing
Prevent food-contamination. Food storage and Transportation
. Turns raw food materials into attractive, marketable products. Provide employment to a large population.
