A method is described for the preparation of lactulose by isomerizing lactose to lactulose, followed by complexing lactulose to boric acid. The isomerization reaction is carried out in alkaline solution, and it is followed by splitting the lactulose-borate complex in acidic solution and separating the two components. Separation is achieved by crystallizing boric acid, filtering the crystals out of the product mixture, evaporating the product mixture to form a concentrate, recirculating the concentrate to the crystallization step where it is mixed with fresh reaction mixture in order to provide volume and nuclei for the crystallization of the boric acid in the reaction mixture, then passing the resulting mixture through another filtration step followed by an additional separation step by column chromatography.

Continuous process for the production of lactulose from lactose using

The present invention is drawn to various aspects of automated excision of undesirable material (and optionally excision of bone) from meat, and automated production of starting material for restructured meat, including: (a) an apparatus and method generally drawn to, optical detection of the location of undesirable material in meat, communication of information regarding the location of the undesirable material to a control means, and excision of the undesirable material from the meat using a high pressure water jet controlled by the control means; (b) a bone location sensor and method of bone location sensing, each employing a plurality of needles, and; (c) a multiple blade slicer.

Automated excision of undesirable material and production of starting

Edible tallow is continuously processed through a crystallizing system to produce three fractions, one of which has physical and thermal properties like those of cocoa butter. Nominal residence time of the crystallizing solution in the system at steady state crystallizing temperature is less than ten minutes.

Continuous fractionation of tallow and production of a cocoa butter-like

A continuous process for the preparation of isopropenyl stearate in which a comelt of stearic acid and zinc stearate is pumped through a reaction zone simultaneously with stabilized propyne. Total reaction time is about 10 minutes.
