Abstract:
The invention relates to a method of preparing a ripening flora, involving a cell weakening step, and the use of one such flora for and/or in the preparation of fermented products, particularly for cheese preparation.
Abstract:
The invention concerns a method and an implementing device, for making a mixture or and emulsion from at least an emulsifier and at least two fluids known to be immiscible, said fluids defining a dispersed phase and a continuous phase. The method is characterised in that the dispersed phase being either contained in an adapted tank, or continuously supplied, it comprises a first step which consists in pressurising the dispersed phase; then in suddenly depressurising said dispersed phase using means generating a coherent jet (5). Then an appropriate emulsifier is introduced into said coherent jet (5) with means for mixing the dispersed phase with said emulsifier thereby providing a resulting coherent jet (9) which is finally contacted with the continuous phase to obtain the mixture or the emulsion.
Abstract:
The invention relates to a method for producing a dehydrated sourdough where a microbiol biomass is homogeneously mixed with a dehydration medium comprised of flour and water in order to produce a wet sourdough, characterised in that the wet sourdough is dehydrated at a temperature lower than 40 DEG C between two successive steps, first at any dehydration speed while the water activity aw is higher than or equal to 0.990 and then, as soon as the water activity aw drops to a value lower than 0.990, the sourdough is dehydrated at a lower hydrous potential gradient corresponding to dehydration rates comprised between -0.5kPa/s and -5.0kPa/s until the water activity aw drops to a value substantially equal to 0.15.
Abstract:
La présente invention concerne un procédé de décontamination microbiologique de produits pulvérulents, de graines ou analogues remarquable en ce qu'il consiste au moins à soumettre le produit pulvérulent à un premier traitement thermique à une température supérieure à 100 °C pendant une courte durée puis, immédiatement après à soumettre ledit produit à un second traitement thermique à une température inférieure à 0 °C pendant une courte durée afin de détruire en tout ou partie les levures, les moisissures, les bactéries ou analogues, initialement présentes sur le produit pulvérulent tout en conservant ses qualités organoleptiques. Un autre objet de l'invention concerne un dispositif de décontamination de produits pulvérulents, de graines ou analogues comprenant au moins une enceinte (1, 2, 20, 21, 40, 50) et des moyens de chauffage (11) et/ou de refroidissement (12) de l'air contenu dans ladite enceinte (1, 2, 20, 21, 40, 50).
Abstract:
L'invention est relative à un procédé de préparation d'une flore d'affinage mettant en œuvre une étape de fragilisation cellulaire au moyen d’un choc osmotique ou d’un choc à hautes pressions, ainsi qu'à l'utilisation d'une telle flore pour et/ou dans la préparation de produits fermentés, en particulier pour la préparation de fromages.
Abstract:
The present invention relates to a method for fabricating cheese by reconstitution from curded pressed paste cheese, which is downgraded or in lumps, when the cheese (1) forming the starting material is divided initially in small lumps (1 c ) of regular shape, characterized in that the divided cheese is subjected, without addition of water or any other ingredient, to a series of operations such as kneading and controlled shearing, and curing at a temperature comprised between 70 DEG C and 80 DEG C.
