A crystallization apparatus for a crystallization of a preliminary product. The crystallization apparatus includes an inlet for receiving the preliminary product, a rotary drive, and a rotatable receiving unit having, on an upper side thereof, a circular surface and / or an annular surface for the crystallization so that, when the rotatable receiving unit is rotated, the preliminary product received can be recrystallized in a defined manner on the circular surface and / or the annular surface and can be discharged as a crystallized product.

To provide solid preparations of human milk oligo saccharides and methods for manufacturing of solid preparations of human milk oligosaccharides.SOLUTION: The present invention provides spray-dried powder consisting essentially of 3-fucosyllactose which has been produced by microbial fermentation, and a nutritional composition containing the spray-dried powder. A method for manufacture of the spray-dried powder comprises the steps of: a) purifying the 3-fucosyllactose from a fermentation broth; b) providing an aqueous solution containing the 3-fucosyllactose of the step a); and c) subjecting the solution of the step b) to spray-drying.SELECTED DRAWING: Figure 1

The present invention provides a process of producing a lactose concentrate, said process comprising the step of subjecting a partially demineralised aqueous lactose isolate to electrodialysis to produce a biotin-reduced lactose isolate containing at least 90% lactose by weight of dry matter and less than 2 mg ash per gram of lactose, and containing:0.02-1.5 mg sodium per gram of lactose;0.02-2 mg potassium per gram of lactose;0.05-1.5 mg chloride per gram of lactose;0.01-0.25 μg biotin per gram of lactose.The present invention also relates to a demineralised lactose concentrate having a reduced biotin content that can be produced by the aforementioned process. The invention further relates to an oligosaccharide-enriched biotin-reduced fraction that is obtained when lactose is separated before or after the electrodialysis step.

The present invention relates to a method for producing crystalline lactose, more particularly lactose obtained from a biotechnological production process.

A lactulose solution end treatment device belongs to the technical field of lactulose production related equipment, and includes a curtain type membrane solid-liquid separation device for separating aluminum hydroxide from raw material liquid, and the interception capacity of the curtain type membrane solid-liquid separation device is configured to intercept aluminum hydroxide flocculation and allow lactulose molecules to pass through. The curtain type membrane solid-liquid separation device is used to realize the filtration and separation of aluminum hydroxide, and the advantage is that the interception capacity of the organic membrane in the curtain type membrane solid-liquid separation device can make the lactulose molecules pass through, and the aluminum hydroxide flocculation is intercepted, so that the separation of the lactulose raw material liquid is realized. The lactulose solution end treatment device provided by the utility model can realize efficient separation of aluminum hydroxide in the raw material liquid, and improve the final yield of lactulose.
