 Preparation of a blue cheese flavour - Patent 4832964
A blue cheese flavorant is prepared by first hydrolyzing a reaction medium of an animal or vegetable fats and oils having C.sub.4 to C.sub.14 triglycerides with an enzyme which liberates C.sub.4 to C.sub.14 fatty acids from the fats and oils in a reaction mixture.
A culture medium containing the liberated fatty acids, and which may include unhydrolyzed fats and oils from the reaction mixture, is prepared and inoculated with spores of Penicillium roqueforti.
Although Penicillium roqueforti mycelia may be used in the fermentation, the spores are preferred because the mycelial stage has a tendency to metabolise the methyl ketones further whereas the spore stage does not and because the mycelia are more susceptible to fatty acid toxicity than the spores.

 Roquefort Papillon - french cheese   (Site not responding. Last check: )
Roquefort is made with pure sheep’s milk, which is inoculated with a special type of blue mold (Penicillium roqueforti).
Cheesemakers first transform the raw milk into a simple cheese with a noble type of mold added to it, the Penicillium roqueforti (mold obtained from bread left to mold in the caves of Combalou mountains).
The well-known green-blue marbled appearance of the paste is due to the Penicillium roqueforti, which develops in the cool, damp air swept in through the fleurines, vertical fissures serving as wind holes.

 What is Roquefort?
The PDO defines that Roquefort must be produced following certain regulations, such as the use of milk from a particular breed of sheep, the location in which the cheese is matured, and the type of bacteria used for the maturation process.
Spores of the bacteria Penicillium roqueforti are then added to these vats, allowing the milk to ferment into curds.
Once there is sufficient Penicillium roqueforti in the cheese, the loaves are wrapped up and left to mature under lower temperatures.

 Living France - Buying a house in France, moving to France and owning French property
Made from ewe’s milk, the cheese is matured in the cellars in Roquefort-sur-Soulzon, home of the famous penicillium roqueforti that gives the cheese its taste and colour.The natural cellars were created by the subsidence of the rock which resulted in naturally formed caves, ventilated through fleurines, natural fault lines in the rock.
Here the role of the maître affineur is critical; he has to judge when the penicillium roqueforti has developed sufficiently and thus when to halt further ripening.
In order to kill off the microorganism, the cheeses are wrapped in tinfoil which effectively suffocates the mould, and are then put into cold storage for a minimum of three months and left to mature, before being packaged and dispatched throughout the world.

This mold grows within the cheese and breaks down complex organic molecules into simpler ones, smoothing out the fibrous structure of the cheese and providing the sharp flavor and smell associated with blue cheeses.

Since activation, that is, the termination of the dormancy of the spore, is the initial stage of germination, an examination of the activation process itself makes a logical starting point to the study of the biochemical aspects of germination.
This communication describes the effect of different physiological agents on the ability of spores of Penicillium roqueforti to oxidize octanoic acid and hence provides a method of assessing the influence of these agents on activation.
The method may also be applicable for studies of the effects of these agents on the subsequent stages of the germination process.
