Immunostimulating glycopeptides obtainable from the cell walls of immunostimulating bacteria belonging to the Mycobacteriaceae or Actinomycetaceae Family and methods of isolating the glycopeptides.

A process for the production of an aromatic spice extract, which comprises (a) grinding a spice and collecting an aromatic fraction A, consisting of the gases given off during grinding, (b) treating the spice with an apolar organic solvent so as to obtain an aromatic fraction B contained in this apolar solvent, and (c) treating the spice with at least one polar solvent so as to obtain an aromatic fraction C contained in this polar solvent, The combination of the aromatic fractions A, B and C con...

A safe, effective first-pass inhibiting citrus-derived substance.

A water-insoluble plant powder obtained by preparing a dry powder of green plant juice squeezed from a fresh raw edible green plant (e.g., barley) and removing water-soluble components from the dry powder, and a green coloring material obtained by further extracting it with a polar organic solvent. They are useful in food products.

Disclosed are a propolis extract where the peculiar odor of propolis is reduced by decreasing the odorizing ingredients, a process to produce the propolis extract which comprises soaking propolis in a hydrophilic organic solvent to effect extraction and treating the liquid layer in the resultant extract with an anion-exchange resin, and a biologically active composition comprising the propolis extract.

A propolis extract having a reduced peculiar odor is prepared by deceasing the amount of odorizing ingredients. This propolis extract can be used to prepare biologically active compositions.

A new coffee extraction process has been discovered whereby a high concentration coffee extract, about 30-41 percent solids by weight of extract, can be produced in an ordinary percolation set with little, if any, loss of extraction yield. The key steps in this process include the use of intercolumn heaters to raise the temperature of the extraction liquor as it passes from column to column and reversing the flow of the extraction liquor through the extraction columns, at least in the spent end ...

A friction plate for placement under an automotive vehicle wheel so to gain traction when on ice or snow, the device comprising a woven mat with downward extending ice nails to hold against the ice, and upwardly extending nail heads for engaging the tire.

Coffee extracts are processed in a continuous countercurrent process of split extraction to obtain (1) atmospheric solids, (2) a push-out of low concentration, mainly atmospheric solids and (3) autoclave solids. Each stream can be further processed separately before recombining to achieve desired flavor characteristics.

A high quality coffee extract is prepared using a commercial percolation system utilizing a superficial velocity of aqueous extraction liquid past the roasted and ground coffee of at least about 0.50 ft/min in the fresh stage extraction column of a percolator set.
