Whole Milk (Rich) in gelato
Whole milk (rich) is standardized cow's milk at about 3.5% milkfat and 12.5% total solids. In gelato it is the primary base liquid, supplying water, milk fat, and milk solids-not-fat (MSNF: protein, lactose, and minerals) that build body and creamy mouthfeel.

Whole milk is the workhorse base of most gelato white mixes, typically making up the largest single share of the recipe. Its main technical value is MSNF: proteins and minerals emulsify and stabilize the mix while binding free water for a smoother, denser body, and lactose adds a little structure. Its direct effect on sweetness and hardness is small, because lactose has low sweetening power (POD around 16 vs sucrose 100) and contributes only modest freezing-point depression (PAC near 4.8 per 100 g of milk). Keep total MSNF in the finished mix roughly 8-12%; above about 12-13% the lactose can crystallize during storage and cause a sandy, gritty texture. Because milk is ~87-88% water, most of the mix's PAC, POD, and total solids must come from added sugars and cream, not from the milk itself.
Origin & background
Milk has been the foundation of frozen dairy desserts since the origins of gelato in Renaissance Italy. 'Whole' milk is a modern regulatory grade: the U.S. federal standard of identity (21 CFR 131.110) requires whole milk to contain not less than 3.25% milkfat and 8.25% milk solids-not-fat, while European and classic dairy references cite roughly 3.5% fat for full-fat/rich milk. Standardization of fat content became routine after the spread of the centrifugal cream separator in the late 19th century.
