Abstract— The effect of humidity on isomerization during grinding of α‐monohydrate, α‐anhydrate and β‐anhydrate of lactose was investigated. Samples were ground in an agate centrifugal ball mill at 270 rev min −1 at room temperature (21°C) and at 5 and 60% relative humidity. Crystallinity of the ground lactose was measured by Hermans' method from the powder X‐ray diffraction ...

Apr 12, 2011· Abstract. Abstract— Isomerization during grinding of solid-state α-monohydrate, α-anhydrate and β-anhydrate of lactose was investigated. Samples were ground in an agate centrifugal ball-mill at 270 rev min −1 at room temperature (20°C). The crystallinity of ground lactose was measured by Hermans' method from the powder X-ray diffraction profiles.

Food grade lactose is produced by concentrating whey or permeate (a co-product of whey protein concentrate production) to supersaturate the lactose, then removing and drying the lactose crystals. Special processes of crystallization, as well as grinding and fractionated sifting, produce types of lactose which differ in particle size distribution.

Spiral jet milling is a size reduction process used in various industries, ranging from paints to food and pharmaceuticals. It has great benefit in the pharmaceutical industry due to its ability to reduce particulate solids to micron sizes and narrow size distributions. Despite its heavy usage, the underlying size reduction mechanism of the mill is not well understood.

Lactose is the most important carbohydrate of the milk of most species. Lactose is the first and only carbohydrate every newborn mammal (including human) consumes in significant amounts. Lactose is made from sweet whey. Lactose is produced by crystallizing lactose from fresh sweet dairy whey, drying and then grinding into a fine powder.
