Definitions
- the present invention relates to new strains of Penicillium camemberti and to their use for the preparation of food products, for example of dairy and / or vegetable origin, such as the ripening of soft cheeses with a flowered and / or mixed rind. , especially Camembert.
- Penicillium camemberti is an ascomycete fungus used in cheese making as surface flora of products where it gives them their white “flower” and where it contributes to the development of ripening by its lipolytic properties , proteolytics and its deacidifying power. This fungus is also designated Penicillium album, Penicillium candidum or Penicillium biforme.
- Ripening is one of the stages in the production of a traditional cheese with a flowery and / or mixed rind, which comes after the other classic stages:
- curdling during which the milk is allowed to coagulate thanks to the action of a coagulant and ferments producing lactic acid.
- the coagulant is traditionally rennet extracted from one of the stomachs of the calf and made up of the enzymes chymosin and pepsin. Today, it is most often replaced by coagulants of microbial or vegetable origin that the man of the art calls by analogy also "rennet". The term will be used in this sense in the following to describe any coagulant used in cheese production whatever its origin.
- draining consisting of the separation of the curd, the solid phase, of the whey, the liquid phase, and
- salting which conditions the future taste of the cheese and which can be done either by soaking in brine, or dry by sprinkling the surfaces of the cheese.
- the cheese is covered on all of its faces with P. camemberti to carry out the ripening step; alternatively or in addition, the ripening flora can also be mixed with the milk before the curdling step.
- the different cheese transformations take place under the double action of an enzyme and microorganisms living on the surface and inside of the cheese.
- the salt migrates into the dough and the crust begins to form.
- the relay is then taken up by the ferments of milk which play a predominant role in the flavor of the cheese.
- especially surface ferments, namely bacteria, yeasts, fungi, especially P. camemberti complete this maturation process.
- a flowered rind designates the rind that develops on the surface of the cheese by growth of a surface flora of the Penicillium type or of the Geotrichum type (such as Geotrichum candidum), it generally has a white and fluffy appearance; a mixed crust is a crust obtained by the development of a surface flora associating at least one strain of the Penicillium type and at least one strain of the Geotrichum type (such as Geotrichum candidum), or at least one strain of the Penicillium type or at least a Geotrichum type strain (such as Geotrichum candidum) and at least one other surface strain.
- the inventors have identified new strains of P. camemberti having a longer latency time, in particular greater than 19 days, in particular useful for correcting crust quality problems and slowing down the biological aging of cheeses with flowering rind. and / or mixed.
- the present invention thus relates to a strain of Penicillium camemberti having a latency time on dairy culture medium at 4 ° C greater than 19 days and preferably greater than 20, 21 or 22 days.
- latency time means the time interval which elapses between the inoculation of a strain on a culture medium and the appearance perceptible to the eye of the mycelium of said strain.
- dairy culture medium is meant an agar culture medium comprising milk and / or caseins and / or milk fat and / or lactose ...; it can be for example milk agar, tributyrin agar ...; preferably, the dairy culture medium is the MRP medium, the composition of which is detailed in the experimental part which follows.

- the strain of P. camemberti of the present invention also has a recovery speed on dairy culture medium at 4 ° C. of less than 0.15 cm / day, preferably less than or equal to 0.12 cm / day , 0.10 cm / day or 0.05 cm / day.
- the speed of recovery of a strain is understood to mean the speed of radial growth of the strain obtained by a simple linear model of the diameter of the colonies as a function of time; the recovery speed being the directing coefficient of the regression line.
- the strain of P. camemberti according to the invention is chosen from the group consisting of strains: 1-5311, 1-5305 and 1-5310 and preferably in the group consisting of strains: 1-5305 and 1-5310, more preferably, the strain of P. camemberti according to the invention is the strain 1-5305.
