Sustainable and Cost-Effective Lactose Whitening

May 17, 2024 Michael Christensen Anhydro Spray Dryers

Lactose powder, a common ingredient in various food and pharmaceutical products, is often used for its binding and bulking properties. However, some applications such as cheese powders, milk/dairy powders, infant/baby formulas, and pharmaceuticals may require lactose powder to be whitened to meet industry and consumer standards. Whitening lactose powder involves the removal of impurities and colorants that may affect its natural white appearance. There are two popular methods for whitening lactose powders – carbon cartridges and lactose washing – but there’s also a new, innovative, more sustainable, and cost-effective solution.
