    • A novel high-density liquid or pasty yeast preparation, which comprises approximately 1-20 % (w/w) of a polyhydroxy compound selected from a group comprising propylene glycol, glycerol, non-fermentable mono- or oligosaccharides or sugar alcohols, soluble oligo- or polymeric carbohydrates and polyethylene glycol, or mixtures thereof, and fresh yeast. The high-density yeast preparation has a density of more than 800 g yeast (27-29 % dry matter) per 1 liter of the preparation, and the concentration of the polyhydroxy compound in the extracellular liquid is 5-50 % (w/v). The preparation has an improved capability of retaining its activeness, it dissolves instantly and is easily batched, uniformly suspendable and tolerant of repeated freezing and thawing. The liquid high-density yeast preparation has a viscosity of less than 200 centiPoise (cP) at 20 C. Methods for producing the high-density yeast preparation as well as its use for the preparation of improved quality baker's, brewer's, distiller's and wine yeast are disclosed.
    • 一种新型高密度液体或糊状酵母制剂,其包含约1-20%(w / w)的选自丙二醇,甘油,不可发酵的单糖或寡糖或糖醇的多羟基化合物,可溶性寡聚 - 或聚合碳水化合物和聚乙二醇,或其混合物和新鲜酵母。 高密度酵母制剂每1升制剂的密度高于800g酵母(27-29%干物质),细胞外液中多羟基化合物的浓度为5-50%(w / v )。 该制剂具有保持其活性的改进能力,它立即溶解,容易分批,均匀悬浮并且耐受反复冷冻和解冻。 液体高密度酵母制剂在20℃下的粘度小于200厘泊(cP)。生产高密度酵母制剂的方法以及其用于制备改良质量面包师,啤酒酿造商,酒糟和酒酵母的用途 被披露。
