Abstract: The invention relates to a milk product which includes 0 to 40% fat, 5% to 23% non-fat solids, a mixture of at least two emulsifiers, a foam stabilizer, and water. The product forms a foam at room temperature when shaken or may be foamed with a foaming device. The emulsifiers include propylene glycol monostearate, sorbitan tristearate, and unsaturated monoglyceride, and the foam stabilizer is a sodium alginate or a mixture of microcrystalline cellulose and carboxymethylcellulose.

Abstract: Frozen aerated products having a mean ice crystal diameter of between about 20 and 60 microns and a mean equivalent diameter of about 32 to 36 microns and a homogeneous distribution of fats and proteins. These products are manufactured with a device having two endless screws, identical and parallel, meshing with each other and turning in the same direction, located in a casing fitted at one of its ends with a nozzle and at the other end with an inlet for feeding with composition to be frozen and, in an intermediate area, with an inlet for feeding air. The casing is provided with a jacket in which refrigerating fluids circulate.

Abstract: Frozen concentrated milk is prepared by introducing a concentrated milk, such as a concentrated whole or skim milk, into the barrel of an apparatus for extrusion of a product which contains at least one screw which is rotated for transport of the concentrated milk through the apparatus barrel for extrusion of product through an extrusion apparatus product exit die, and during the transport of the concentrated milk through the extrusion apparatus, the concentrated milk is cooled to a temperature of equal to or lower than −8° C. to obtain, from the exit die, frozen concentrated milk.

Abstract: The invention concerns a process for the preparation of a finely divided soya product, wherein:a) soya beans are dehulled dry,b) the said beans are milled continuously for a short period in the presence of hot water,c) this milled material is heat treated at a temperature above 148.degree. C., the minimum residence time at 148.degree. C. being 30 sec and the minimum residence time at higher temperatures being shorter andd) this suspension is immediately passed through a back-pressure valve.

Abstract: A process for the preparation of a soluble protein fraction which comprises extracting a protein-containing vegetable material with an aqueous medium at a pH value below 4, treating the resulting aqueous extract by gel filtration at a pH value below 4 and recovering a soluble protein fraction by elution.
