Method for making a composition of yeast placed on boards comprising (a) about 25% up to about 75% of a plasma micro -organism by weight of the total composition weight； (b) about more than 20% up to about 60% by flavor weight or fragrance, the total weight of the composite (c) about 1% to about 25% desiccant； d) about 4% up to about lt； 10% water；Where the average particle size distribution by weight of the composition is about more than 100 micrometers up to about one millimetre. A method for making a yeast composition placed on plates comprising (i) a homogeneous cake, in which the cake is made by mixing, is also provided in this document, at a temperature ranging from 20 (c) to about 90 (a) a plasma micro -organism in a qua (b) a fragrance flavor or oil supplied in a quantity of at least 0,01% up to about 60% by weight of the total weight of the cake；(c) water supplied in a quantity of about 5% up to about 90% by weight of the total weight of the cake； in which the ratio of micro -organism to water in the cake supplied in a quantity by weight of about 4,5:1 to 0,5:1； with (ii) at least about 40% up to about 99,9%,(iii) optionally of about 0,2 to about 2% by weight of a flow agent of the total composition weight to form a uniform blender. B. Sift the combined blender to form a powder with a particle size of about 100 to 1.000 micrometers.método para fazer uma composição de levedura colocada em placas que compreende a) cerca de 25% até cerca de 75% de um microrganismo plasmolisado em peso do peso total da composição； b) cerca de pelo menos mais de 20% até cerca de 60% em peso de sabor ou fragrância, do peso total da composição c) cerca de 1% até cerca de 25% dessecante； d) cerca de 4% até cerca de <； 10% água； em que a distribuição média do tamanho de partícula por peso da composição é de cerca de mais de 100 micrômetros até cerca de 1 milímetro. também é fornecido no presente documento um método para fazer uma composição de levedura colocada em placas que comp
