A process for decolorizing an aqueous solution of methyl glucoside, the solution containing at least one color component and at least one sugar component, is disclosed. The process comprises the steps of providing the aqueous solution of MeG; adding to said solution an amount of yeast or other sugar-converting microorganism sufficient to reduce the level of said sugar component; preferably further adding to the solution an amount of activated carbon sufficient to assist the color component in the solution; and recovering the solution to yield a decolorized, low-sugar solution of MeG. Also disclosed is a process comprising the steps of providing a solution containing MeG and dextrose; and adding to the solution an amount of a sugar-converting microorganism sufficient to reduce the level of the dextrose in the solution. Decolorized MeG solutions prepared by the foregoing processes also are disclosed.

Glycoside products are successfully prepared directly from aqueous saccharide solutions or syrups, and with acceptably low levels of undesired homopolymerized saccharide by-products, by dissolving same in the desired alcohol reactant or in an alcohol reactant plus glycoside product mixture and contacting the resulting homogeneous aqueous saccharide solution and alcohol-containing reaction medium with an acid catalyst in a fashion such that no separate or distinct, substantially alcohol reactant-free aqueous saccharide solution-containing phase is permitted to come into contact with said acid catalyst material under conditions conductive to homopolymerization of said saccharide reactant.

A method of improving the utility of corn bran (i.e., hulls derived from milling) is provided. The corn bran is crosslinked with a polyvalent compound capable of forming a plurality of covalent bonds to one or more constituents of the corn bran. The crosslinked corn bran finds particular utility in papermaking. Paper furnishes and paper products derived therefrom are also provided.

Crosslinked corn bran and utilization in papermaking

New anionic derivatives of mono and polyglycosides which are surface-active agents are described which anionic derivatives have the general formula ##STR1## wherein G is a glycosyl moiety which is derived from a reducing sugar selected from the group consisting of fructose, glucose, mannose, galactose, talose, gulose, allose, altrose, idose, arabinose, xylose, lyxose, ribose or mixtures thereof,

Ionic derivatives of alkyl mono and polyglycosides

Glycoside products are successfully prepared directly from aqueous saccharide solutions or syrups, and with acceptably low levels of undesired higher polysaccharide by-products, by dissolving same in the desired alcohol reactant and contacting the resulting homogeneous aqueous saccharide+alcohol solution with an acid catalyst material in a fashion such that substantially no separate or distinct, predominantly aqueous saccharide solution phase is permitted to come into contact with said acid catalyst material under conditions conducive to homopolymerization of said saccharide reactant.

Aqueous liquid carpet and upholstery shampoo compositions are provided which comprise a glycoside surfactant, a normally solid, water soluble or water dispersible polymer component and water. In a particularly preferred embodiment, the surfactant ingredient employed consists essentially of one or more glycoside surfactants and utilizes a polymer-containing shampoo modifier system of the type disclosed in U.S. Pat. No. 4,203,859. The indicated compositions are utilized in the cleaning of soiled carpet or upholstery by applying said composition to the soiled carpeting or upholstery; permitting same to dry and harden thereon and thereafter removing at least a portion of the resulting soil-containing polymer residue by vacuuming.

Large diameter starch granules derived from yellow field pea, Pisum sativum (var) and faba bean, Vicia faba L. (Leguminosae) are used to replace scarce arrowroot starch granules as a protective stilt material in microencapsulated coatings, including carbonless copy paper. The 'stilt' material is used to prevent premature rupture of the microcapsules and early release of the microencapsulated materials. It has been discovered that the natural granule size, and other granule properties of the yellow field pea and faba bean starches are ideally suited to replace arrowroot starch granules as a protective material. In certain coating processes in which the temperature at the coated surface exceeds the normal pasting temperature of these starch granules, the pasting temperature of the granules can be raised by a crosslinking reaction under temperature and pH conditions to preserve the granular structure of the starch particles. A polyfunctional crosslinking agent, such as epichlorohydrin, phosphorus oxychloride, acrolein, or urea-formaldehyde can be used. Under highly alkaline conditions, using phosphorus oxychloride in a stepwise reaction procedure, it is possible to increase the pasting temperature of the starch granules by more than 25.degree. F. These large diameter starch particles may also be used for other purposes, such as for anti-offset powders in lithography, either with or without crosslinking or other derivatization to further improve chemical and physical properties. These starches are also useful as absorbable dusting powders. The large granule starches derived from most varieties of peas and beans can be used in the same manner.

Stilt material for pressure sensitive microencapsulated coatings

Large diameter legume starch granules including starches derived from yellow field pea, Pisum sativum (var) and faba bean, Vicia faba L. (Leguminosae) which have been treated to remove protein and fiber, and to improve color are used to replace scarce arrowroot starch granules as a protective stilt material in microencapsulated coatings, including carbonless copy paper. The 'stilt' material is used to prevent premature rupture of the microcapsules and early release of the microencapsulated materials. It has been discovered that the natural granule size, and other granule properties of the yellow field pea and faba bean starches are ideally suited to replace arrowroot starch granules as a protective material when the naturally occurring protein and fiber have been removed, and the color improved. In certain coating processes in which the temperature at the coated surface exceeds the normal pasting temperature of these starch granules, the pasting temperature of the granules can be raised by a crosslinking reaction under temperature and pH conditions to preserve the granular structure of the starch particles. A polyfunctional crosslinking agent, such as epichlorohydrin, phosphorus oxychloride, sodium trimetaphosphate, acrolein, or urea formaldehyde can be used. Under high alkaline conditions, using phosphorus oxychloride in a stepwise reaction procedure, it is possible to increase the pasting temperature of the starch granules by more than 25.degree. F. These fiber and protein free, large diameter legume starch particles may also be used for other purposes, such as for anti-offset powders in lithography, either with or without crosslinking or other derivatization to further improve chemical and physical properties. These starches are also useful an absorbable dusting powders. The large granule starches derived from most varieties of peas and beans can be used in the same manner.
