A dairy product comprising a sweetened dairy composition with a mass ratio of lactose to glucose equal to 1.0:2.7 to 2.6:1.5 and a mass ratio of lactose to galactose equal to 1.0:2.2 to 2.6:1.1. In a second aspect, a method comprises hydrolyzing lactose in the starting dairy composition in a lactase-catalyzed hydrolysis reaction and deactivating the reaction to provide a lactose percent conversion of 46 to 80 wt. %. In a third aspect, a dairy product comprises a fermented sweetened dairy composition comprising a lactose:glucose mass ratio of 0.01:2.4 to 1.0:1.0 and a lactose:galactose mass ratio of 0.01:2.7 to 1.0:1.0. In a fourth aspect, a method comprises hydrolyzing and fermenting lactose in a starting dairy composition, thereby providing a fermented sweetened dairy composition with a lactose percent conversion of 80 to 100 wt. %.

The present invention describes a process for in situ generation of stable GOS in different dairy products by the use of a transgalactosylating -galactosidase.

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.

The present invention relates to lactose-reduced milk-related products, and particularly such products having a long shelf-life. Additionally, the invention relates to a method of producing such products and a milk processing plant for the implementation of the method.

The invention relates to a milk-based formulation with a reduced carbohydrate content, having a ratio of carbohydrates to protein of at most 1.1, a protein content of at least 5.4% on dry matter basis, and a ratio of ash to protein is substantially similar to that of a milk raw material used as a starting material, and a method for the preparation thereof. The milk-based formulation can be used in the preparation of a recombined milk product with a reduced lactose content, having a full taste of normal milk without any deficiencies in its organoleptic properties.

The present invention relates to a method for producing a dairy product using an enzyme having lactase activity.

Certain embodiments of the disclosure are directed to modified Bacillus spp. host cells expressing/producing -galactosidase and/or lactase enzymes and the use of such enzymes for the production of galactooligosaccharide (GOS) compositions in one or more dairy related end products. More particularly, certain embodiments are directed to expressing/producing such -galactosidase and/or lactase enzymes in modified Bacillus spp. host cells, wherein such enzymes produced and purified from the modified Bacillus host cells are free of unwanted/undesirable enzymatic side activities including, but not limited to, unwanted/undesirable lipase side activities, phospholipase side activities, side activities, cellulase side activities, pectinase side activities, amylase side activities, protease side activities, mannanase side activities and the like.

The invention relates to methods for making strained acidic, for example fermented, dairy products having reduced carbohydrates, compositions comprising strained acidic, for example fermented, dairy products having reduced carbohydrates, and methods for using such compositions, as well as products generated using strained acidic, for example fermented, dairy products having reduced carbohydrates.

The present invention relates to a process for the production of a dairy composition from a starting material containing lactose. The present invention also relates to the compositions produced by the process of the invention as well as the foods and drinks containing the compositions.

The present invention relates to milk products comprising a high amount of in situ produced galactooligosaccharides (GOS) and methods of producing same. Milk substrate having a lactose content of at least 20 wt % lactose is treated with an enzyme having transgalactosylating activity. The transgalactosylating activity of said enzyme may have been increased via glycation of lysine and/or arginine residues by incubation of said enzyme with high concentrations of glucose at elevated temperatures.
