A bioprocess for producing carboxylic acids, alcohols and aldehydes is provided by culturingsp. in a fermentation medium containing various defined substrates.

[object Object]

A food additive useful for lowering serum cholesterol in humans contains a sterol or stanol ester of a fatty acid or a dicarboxylic acid ester of a sterol or stanol made by reacting a sterol, stanol and a carboxylic acid in the presence of an effective amount of a catalyst selected from the group consisting of calcium oxide, calcium hydroxide, a calcium salt of a carboxylic acid, magnesium hydroxide and combinations thereof described herein below.

Food additive compositions containing sterol esters, solubilizing agents, dispersants and antioxidants

Processes for preparing sterol esters

Sterol esters as food additives

The invention relates to the use of nanoscale sterols and/or sterol esters with particle diameters of 10 to 300 nm as food additives and as active substances for the production of hypocholesterolemic agents. The particular fineness of the particles promotes more rapid absorption by the blood serum after oral ingestion by comparison with conventional sterols and sterol esters.

Use of nanoscale sterols and sterol esters

A composition containing: (a) a gemini surfactant selected from the group consisting of a dimer alcohol-bis-sulfate, a dimer alcohol-bis-ether sulfate, a trimer alcohol-tris-sulfate, a trimer alcohol-tris-ether sulfate, and mixtures thereof; (b) aluminum chlorohydrate; and (c) a component selected from the group consisting of an esterase inhibitor, a bactericidal agent, a bacteriostatic agent, and mixtures thereof.

Deodorizing formulation

The aliphatic primary alcohols are reacted with a glycose, more especially glucose, in the presence of an acidic catalyst in certain process steps so that particularly light-colored and alkali-stable alkyl glucosides are obtained after a subsequent, compulsory bleaching step, which represents an improvement over known direct synthesis processes. The process may be carried out both on a laboratory scale and also on an industrial production scale.

Process for the direct production of alkyl glycosides

Quaternary ammonium salts of fatty acid hydroxyalkanesulfonic acids are made by reacting a hydroxyalkanesulfonic acid of the formula (I):

Detergent mixtures with improved processability contain 70 to 95% by weight of fatty acid isethionate salts, 5 to 30% by weight of fatty alcohols, 0 to 15% by weight of fatty acids, 0 to 15% by weight of alkyl and/or alkenyl oligoglycosides and 0 to 15% by weight of fatty acid N-alkyl polyhydroxyalkylamides, providing that the quantities add up to 100% by weight. The optionally self-emulsifying mixtures are suitable, for example, for the production of solid or liquid soaps.

Process for the removal of inorganic salts

A process for the production of surface-active alkyl glycosides which is carried out by the transacetalization method with butanol, leads to a new alkyl glycoside as end product which is characterized by high color-stability in alkaline medium; besides a high proportion of alkyl monoglycoside, the product also contains polyglycoside on polyglycose and butyl glucoside.

A collecting agent and method for the recovery of valuable minerals in the froth flotation beneficiation of non-sulfidic ores is provided. The collecting agent is selected from alkyl glycosides, alkenyl glycosides and mixtures thereof. Preferably, the collecting agent is a combination of an alkyl glycoside, an alkenyl glycoside and mixtures thereof with a non-thio ionizable surfactant collector. Glycosides containing from about 2 to 8 glycoside residues may be used. The alkyl and alkenyl components of these glycosides may be linear or branched, may contain from about 2 to 18 carbon atoms and may optionally contain a hydroxyl group or an ether linkage.

Derivatives of tricyclo-[5.2.1.0.sup.2,6 ]-dec-3-ene corresponding to the following general formula ##STR1## in which R.sup.1 is hydrogen; a linear or branched C.sub.1 -C.sub.8 alkyl radical; an acyl radical R.sup.2 -CO, where R.sup.2 is hydrogen or a linear or branched C.sub.1 -C.sub.18 alkyl or alkenyl radical; or a hydroxyalkyl radical ##STR2## in which R.sup.3 and R.sup.4 independently of one another may be hydrogen or a hydroxy group and m and n are integers of 0 to 5 and the sum (m+n) is an integer of 1 to 5, with the proviso that at least one of the radicals R.sup.3 and R.sup.4 is a hydroxy group; are used as frothers in the flotation of coal and ores.
