Abstract
A method of production of a homogeneous powdered product from a starting product in a liquid state, the starting product having sugars as at least 60% of its total solids, the method comprising: in the absence of air; pressurizing the starting product to a pressure greater than 1 bar; injecting a gas into the starting product to form a mixture in which the starting product is substantially saturated by the gas; and degassing the mixture into a continuous stream of transport gas such that, on contact with the transport gas, water from the mixture evaporates to leave the homogeneous powdered product.
