Description
Screw‑press extraction mechanically ruptures nut cells at ambient temperature to release lipids, proteins, and carbohydrates into a stable emulsion.
Technical
The process relies on shear forces generated by the rotating screw to disrupt cell membranes, liberating intracellular lipids and proteins that form a colloidal emulsion. Ambient temperature preserves heat‑labile nutrients such as vitamin E and polyunsaturated fatty acids, while controlled pressure prevents thermal denaturation of proteins. The resulting emulsion is stabilized by protein–fat interactions without added emulsifiers.
