Galacto-oligosaccharies (GOS) Standard
v 2.0 | Effective 06/26/2023
Product Definition
Galaco-oligosaccharides (GOSGalacto-oligosaccharides) are non-digestible oligosaccharidesComplex carbohydrates that limit the attachment of microorganisms to the intestine. consisting of 1 to 9 galactose units linked via glycosidic bonds to either terminal glucose or galactose. They are obtained by subjecting a concentrated lactose solution to the action of a β-galactosidase enzymeMolecule that accelerates reactions. Enzymes typically are proteins that act as a biological catalyst. Catalysts are not altered in the reaction. The molecule that the enzyme reacts with is known as the substrate. to produce galacto-oligosaccharides and then further terminating the reaction. The galacto-oligosaccharides may be purified by ultrafiltration, chromatography, ion exchange, electrodialysis, activated carbon filtration or any other safe and suitable process in which all or part of the galacto-oligosaccharides, mineralsGenerally refers to elements other than carbon (C), hydrogen (H), oxygen (O) and nitrogen (N) that are found in dairy products. The term often is used interchangeably with salts and ash., other sugars are concentrated into a viscous syrup or a powder.
GOSGalacto-oligosaccharides for human consumption complies with all provisions of the U.S. Federal Food, Drug, and Cosmetic Act.

Permissible Additives
Galaco-oligosaccharides (GOS) may be pHA measure of the acidity or alkalinity of a material. The pH scale ranges from 0 (acid) to 14 (alkaline) with 7 considered neutral. pH is a measure of the concentration of hydrogen ions and is defined as the negative log of the hydrogen ion concentration. adjusted with appropriate mineral or organicRegulations that refers to the way agricultural products are grown and processed. Regulations vary from country to country but in the U.S., organic crops must be grown without the use of synthetic herbicides, pesticides and fertilizers or bioengineered genes. acid or base. Any pHA measure of the acidity or alkalinity of a material. The pH scale ranges from 0 (acid) to 14 (alkaline) with 7 considered neutral. pH is a measure of the concentration of hydrogen ions and is defined as the negative log of the hydrogen ion concentration. adjustment agent used for this purpose shall be food grade and shall be used in accordance with U.S. current Good Manufacturing Practices and in accordance with its GRASGenerally recognized as safe status, where applicable.
