Provided is a method of preparing ferric carboxymaltose with weight average molecular weight between 100,000 and 400,000. The method includes reacting an oxidized maltodextrin solid with an iron (III) salt solution in acidic and basic conditions in sequence to afford ferric carboxymaltose, wherein the oxidized maltodextrin solid has a dextrose equivalent of less than 4. The ferric carboxymaltose prepared by the method can withstand high-temperature sterilization with high stability and facilitate storage.

A process for preparing a galacto-oligosaccharide product comprises exposing a permeate composition to one or more enzymes that convert one or more compounds in the permeate composition to one or more galacto-oligosaccharide compounds to provide a galacto-oligosaccharide solution, wherein at least about 10% of total sugar, by weight, in the galacto-oligosaccharide solution is in the form of the one or more galacto-oligosaccharide compounds, and concentrating at least a portion of the galacto-oligosaccharide solution to provide a galacto-oligosaccharide syrup. In an example, a galacto-oligosaccharide product, for example made by the process, comprises a dry or substantially dry powder including one or more dried compounds from a permeate composition and at least 20% by weight of one or more galacto-oligosaccharides, wherein the powder is free or substantially free from a drying agent.

Process for the preparation of a galacto-oligosaccharide preparation, which process comprises the step of contacting a lactulose-containing feed with a beta-galactosidase derived from Papiliotrema terrestris. The resulting galacto-oligosaccharide is acceptable to subjects suffering from GOS-related allergy and subjects having lactose intolerance.
