Resins ginger

Oleo Resins. These oily residues, obtained from the solvent extraction of herbs, contain more of the characteristic flavors than do the essential oils. The solvent extraction removes nearly all of the flavor bodies from the herb. The extract solvent is distilled, reduciag the solution to an oily residue. Oleo resias of iaterest to the carbonated beverage iadustry are ginger, celery, and black pepper.

Why had TOCP been added to the ginger extract Tri-orthocresyl phosphate was readily available as it was a constituent of lacquers and varnishes, and was extensively used in the leather industry. It was seen as an ideal solvent to use in the preparation of jake because it was odourless, tasteless, colourless, and cheap. It was also miscible with the resinous extract of ginger and soluble in alcohol. Unfortunately, it was very toxic to humans, a fact that appears not to have been known. At the time there was no law requiring food additives or medicinal products to be tested for safety, and thus the suppliers had broken the law, not by supplying a contaminated and unsafe product, but by selling a product that was not as described in the US pharmacopoeia. In June 1930 twenty-one men and six New York corporations were indicted for conspiracy to violate federal laws. 

These were formerly parenchyma cells which sooner or later lost their protoplasm and nucleus and became receptacles for oil, resin, oleoresin, mucilage or some other secretory substance. They are generally found in parenchyma regions of stems, roots, leaves, flower or fruit parts and frequently possess subeiized walls. Good illustrations of these structures may be seen in Ginger and Calamus.

L.CO2 of Nigerian ginger root gives a 3% yield and S.CO2 has been reported to give 4.6% [13]. Much is dependent on the fractionation of the S.CO2 oleoresin as organic solvents like acetone give 7% and the S.CQz fractionation under certain conditions could leave some resinous material still dissolved in the extract. These resins could precipitate later if the end use application is water based. 

OLEOGUM resins. See gum resin OLEORESiNS. Mixtures of mostly resins and volatile oils. They either occur naturally or are prepared by solvent extraction of botanicals. Prepared oleoresins are made by extracting the oily and resinous materials from botanicals with fat solvents (hexane, acetone, ether, alcohol). The solvent is then removed under vacuum, leaving behind a viscous, semisolid extract that is an oleoresin. Examples of prepared oleoresins are paprika, ginger, and... 

Spans and Tweens have been used to overcome similar problems in the formulation of medicines for internal use. The solubilization of resinous components of tinctures such as benzoin and myrrh in aqueous vehicles and the incorporation of water-soluble ingredients into oily vehicles has been discussed by Stoklosa and Ohmart [230]. Gerding and Sperandio [229] give examples of mixtures of tinctures and fluid extracts which, on addition of polysorbate 20, will not precipitate on dilution. Cetomacrogol 1000 added in small amounts to opiate linctus of squill, syrup of ginger, compound mixtures of camphor, and of lobelia and stramonium has a similar clearing action [207].
