MICROBIOLOGICAL CONTROL [4 records]

Record 1 2019-06-07

English

Subject field(s)
  • Cheese and Dairy Products
  • Food Safety
  • Collaboration with the FAO
DEF

The application to milk of a heat treatment of a lower intensity than pasteurization that aims at reducing the number of microorganisms.

OBS

A general reduction of log 3-4 can be expected. Microorganisms surviving will be heat-stressed and become more vulnerable to subsequent microbiological control measures.

Key term(s)
  • thermisation

French

Domaine(s)
  • Laiterie, beurrerie et fromagerie
  • Salubrité alimentaire
  • Collaboration avec la FAO
DEF

Application au lait d'un traitement thermique d'intensité moindre que la pasteurisation dans le but de réduire le nombre de micro-organismes.

OBS

Une réduction globale de log 3 ou 4 est probable. Les micro-organismes restants subiront un stress thermique qui les rendra plus vulnérables aux mesures de maîtrise microbiologiques ultérieures.

Record 2 2010-10-07

English

Subject field(s)
  • Packaging Techniques
  • Food Preservation and Canning
CONT

Altering the composition of the gaseous environment which a food product contacts reduces the rate of microbiological growth and enzymatic action, reduces the rate of oxidation, and also retards the loss of product water content through respiration of differential water-vapor pressure.... Controlled atmosphere packaging(CAP) means actually controlling the total gaseous environment the product experiences. In commercial practice, it usually means lowering the oxygen and raising the CO2 and assuring that O2 does not diminish to extinction while the respiratory gases are swept out. Controlled atmosphere packaging implies constant control over all gases : O2, CO2, H2O, and ethylene and other trace gases.

OBS

The package acts as a barrier to prevent gas from entering or leaving the container system.

OBS

The term "gas flush packaging" is sometimes used as a synonym for controlled atmosphere packaging.

French

Domaine(s)
  • Techniques d'emballage
  • Conservation des aliments et conserverie
DEF

Mode de conditionnement des denrées alimentaires, telles que les fruits et légumes, permettant de contrôler le phénomène de respiration de ceux-ci, grâce à des ajustements permanents en gaz.

OBS

À la différence de l'atmosphère modifiée au départ, l'atmosphère contrôlée reste identique à elle-même, tout au long du stockage quels que soient les phénomènes de respiration [...]

OBS

Dans ce cas, des appareils appropriés maintiennent les mélanges gazeux dans les proportions d'origine.

Record 4 1987-01-14

English

Subject field(s)
  • Lignite, Graphite and Coal Mining
CONT

Methane control. Explosions of methane in silos and shipholds is an ever present hazard. For the safe handling of coal, effective methane control is essential. In addition to the conventional defences of excluding potential sources of ignition or placing the coal in an inert atmosphere, CANMET has initiated work on the microbiological control of methane.

CONT

A contractor found that methane-oxidized bacteria, isolated from water samples taken from coal mines, remain active over an extended period of time and oxidize methane at an appreciable rate. This method may have applications for methane control in coal mines, coal-storage silos, and shipholds.

French

Domaine(s)
  • Exploit. de charbons fossiles autres que la tourbe
CONT

Un entrepreneur a établi que des bactéries capables d'oxyder le méthane isolées dans des échantillons d'eau recueillis dans des mines de charbon restent actives pendant une longue période de temps et oxydent le méthane à une vitesse appréciable. Cette méthode pourrait être appliquée à l'élimination du méthane dans des mines de charbon, les silos de stockage et les charbonniers.
