Micro-organisms have existed on the planet for billions of years. Microorganisms represent a crucial and various set of microscopic organisms existing as one cell or in a very cluster. Microorganisms perform as populations or assemblages of comparable organisms.

       There area unit four classes of vital microorganisms in foods; "useful" micro-organisms, which can offer the food with organoleptic properties (aromas, acidity, texture) or higher preservation; "weathering" micro-organisms that degrade the organoleptic properties of the food, "hygiene indicator" microorganisms, whose low level of concentration indicates the satisfactoriness of the assembly process; pathogens ", which can cause shopper unhealthiness (through cell invasion and / or poison production).

Originally, the most concern of the person was to preserve the food, for later use. The conservation of the food evokes among USA varied construct or technique employed in order to guard the food, to prolong the employment and therefore the store. Food protection works against chemical science aggression factors (temperature, oxygen, water ...), against insect pests, however additionally and particularly against microorganism alterations (bacteria, yeasts, and molds), Store the food suggests that to supply him the conditions necessary for the prolongation of its period of use while not being subjected to alteration.

-what's a decent diet?

A good diet obeys many principles that area unit diversity, balance, quality and amount. In different words, the diet should give enough energy for your body to operate well.
  There area unit seven food teams that give simplified food classification. This classification is formed by their nutrient content (proteins, lipids, carbohydrates), minerals (iron, calcium, magnesium ...) and vitamins (fat-soluble: A, D, E, K and water-soluble: B, C ...).
Upstream, food teams are ordered consistent with the foremost role they play on the body:

-Functional foods that give fiber, minerals and vitamin area unit protecting and area unit necessary for the right functioning of our body. they're described by the cluster of fruits and vegetables.

-Food builders area unit necessary for the formation of the framework and therefore the development of the mass muscular of our organism. they're described by starch and meat/fish/ egg teams.

-Energy foods give energy for the cells of the body however conjointly reserve substances. they're described by the teams of cereal merchandise, sweet merchandise, and fatty substances.

-The important food - a minimum of the component - is water. She belongs to the drinks cluster.

Microorganisms area unit very varied and active elements of the environment. However, owing to their tiny size, they're usually unnoticed or underestimated. There are, however, 2 areas within which they concern the United States during a explicit way: that of health which of food. so they're the reason behind the alterations of food merchandise and microorganism and plant and mycotic infections that we have a tendency to contract.

The determination of microorganisms is critical to permit internal control and interference of infectious risks in chemical materials. so as to guard the health of shoppers, the French Association for Standardization has outlined obligatory microbiological criteria for the various forms of food from water to well-done dishes, as well as fruits and vegetables.
