Abstract: An improved process of gum extraction from whole yellow mustard seed is described. The process is time temperature interdependent. In a first step the seed is treated in water, preferably at elevated temperature, the extract is then separated, preferably mechanically, more preferably by a perforated centrifuge, or even more preferably by a slitted centrifuge. The aqueous extract on precipitation and drying gives a gum with pseudoplastic properties similar to those of xanthan gum. The extraction using mechanical separation, especially by a perforated bowl centrifuge, which can be slitted, is suitable for industrial scale extraction of the yellow mustard seed. A centrifuge adapted for juice extraction is suitable. The gum produced under these conditions exhibits unique properties dramatically different from those reported from other previous processes, in both composition and viscosities.

Abstract: Edible fats and oils are extracted from oil-bearing materials by loading the raw materials onto an inlet end of a flat and fixed conveying surface having elongate slits therein. The materials are conveyed from the inlet end to the outlet end of the conveying surface by scrapers moved by endless chains. Oil extracting solvent is sprayed onto the material on the conveying surface, to produce miscella, which flows through the slits in the surface and into hoppers beneath the surface. The miscella is circulated back to additional sprayers located upstream of the solvent sprayers for spraying the miscella onto the upstream end of the conveying surface. The resulting concentrated miscella is collected in hoppers beneath the surface and delivered to a further use.
