Whole Milk Powder in gelato
Whole milk powder is spray-dried whole cow's milk (~97% solids), delivering milkfat, milk protein, and lactose in one concentrated ingredient. In gelato it boosts both fat and milk solids-not-fat (MSNF) simultaneously.

Whole milk powder is the tool for raising MSNF and fat at once when you want a richer, chewier body without adding water. Its lactose contributes meaningful PAC (freezing-point depression, coefficient ~100 like sucrose per gram) but very little sweetness (POD only ~16), so it firms structure and improves creaminess without making the mix sweeter. Because lactose crystallizes above ~13% of the water phase, keep total MSNF under roughly 10-12% to avoid a sandy texture. Use whole milk powder when you also need the extra fat; choose skim milk powder when you want MSNF alone.
Origin & background
Concentrating milk by drying dates to antiquity, but the industrial process began with spray drying: American inventor Samuel Percy received a U.S. patent for spray-drying liquids in 1872, and roller and spray drying were commercialized for milk in the early 1900s. Whole milk powder became a global dairy commodity, standardized by bodies such as Codex Alimentarius (min. 26% milkfat, max ~5% moisture).
