Abstract: Novel polynuclear hindered phenols having three hindered phenol groups each bonded through a methylene group to a substituted aromatic nucleus and methods of making same are provided which have stabilizing activity in organic substances normally susceptible to oxidative degradation.

Abstract: A method for preventing greening due to chlorophyll formation in raw unpeeled cold-stored potato tubers exposed to light prior to and including retail sale which comprises spraying or dipping the tubers in an aqueous emulsion containing a single surfactant so as to form a thin continuous film in and on the surface of the tuber which is relatively impermeable to carbon dioxide thereby ensuring an atmosphere containing at least 15% CO.sub.2 within the film and in the tuber. The surfactant preferably contains long chain fatty acid moieties and polyoxyalkylene or polyhydroxy moieties, and has an HLB rating below about 15. A modified process involves the addition of an organic acid, selected from aliphatic mono- and polycarboxylic acids having from 2-6 carbon atoms and at least one hydroxy or oxo group, and lactones thereof, excepting those dicarboxylic acids which readily form internal anhydrides, to the surfactant mixture in order to "tighten" the surfactant film formed on the tubers under treatment.

Abstract: A method of stabilizing oxidation susceptible food against oxidation comprising adding to the food a synergistic antioxidant composition comprising a synthetic phenolic-type antioxidant, butylated hydroxyanisole (BHA), and the solids (or solids and liquids) from certain naturally occurring spices or herbs.

Abstract: Novel, nonabsorbable antioxidants of the general formula (An).sub.n R wherein An is a means for preventing oxidation of an oxidizable material, R is a means for essentially restricting the absorption of An in a biological environment, .about. is a means for covalently bonding An to R for a prolonged time, and n is at least one. The nonabsorbable antioxidants are useful as stabilizers in oxidizable materials without any substantial absorption of the antioxidant in the biological environment.

Abstract: Methylenebis(dicyclopentyl phenols) in which at least one cyclopentyl group is ortho to the phenolic hydroxy group are effective antioxidants in a broad range of organic materials including mineral and synthetic lubricating oil and polyolefins.

Abstract: Polymeric hydroquinones of the structure ##STR1## , wherein n is from 3 to 10,000 inclusive and R and R' independently are hydrogen or a lower alkyl, are disclosed, as is the preparation and the use of such materials, especially as nonabsorbable polymeric antioxidants for edible materials.

Abstract: Process for increasing the shelf life of precooked dehydrated protein and oil containing ingredients for foods by heating an emulsion-suspension of said peanuts to high temperatures and dehydrating the cooked emulsion-suspension, also adjusting the texture of said dehydrated material by processing treatments prior to cooking and dehydration, and the oil-protein ratio by removing part or all of the oil from the peanuts by mechanical means or by extraction, respectively, or by mixing ground peanuts in predetermined amounts with materials poor in fat and rich in proteins. The invention also relates to the precooked dehydrated ingredients so made and the food products containing the same. This is a continuation-in-part of application Ser. No. 187,837, filed Oct. 8, 1971 now U.S. Pat. No. 3,800,056 which is a CIP of Ser. No. 839,673, filed 7/7/69 now Pat. No. 3,689,287.

Abstract: An aqueous composition includes a normally biodegradable component and contains tertiary butyl hydroquinone to inhibit microbial growth. Oxidative rancidity is also controlled when the composition has a fat or oil content. A method is described which adds tertiary butyl hydroquinone to aqueous biodegradable materials in concentrations that inhibit microbial growth.

Abstract: Polymeric phenols of the formula ##STR1## WHEREIN N IS AN INTEGER FROM 3 TO 2,000, R.sub.1 is a lower alkyl and R.sub.2 is hydrogen or a lower alkyl, are disclosed. Their preparation and preferred use as antioxidants, especially nonabsorbable food antioxidants, are also disclosed.

Abstract: Raw fruits and vegetables are treated with an aqueous solution having a pH between about 4 and 7.5 and containing a selected ascorbate ion concentration in order to maintain desirable color, texture, odor and flavor characteristics when the fruit and vegetables are stored at aerobic refrigeration conditions for extended periods.

Abstract: Phenolic polymers formed by the reaction of divinylbenzene with a mixture of hydroxyanisole, tertiary butylhydroquinone, tertiary butyl phenol and bisphenol A (and optionally para-cresol) under condensation conditions in the presence of a phenol ortho alkylation catalyst are disclosed. These materials find use as oil-soluble antioxidants especially for edibles.

Abstract: Synergistic antioxidant compositions useful as additives for edible fats and oils comprising ascorbic acid and rac. 6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid are described.

Abstract: Butylated hydroxy anisole functions as an antimicrobial agent in hydrous material capable of supporting microbial growth when used in excess of about 0.02 percent by weight of the hydrous material.

Abstract: Substances which are subject to microbial spoilage are preserved by addition of a cinnamyl phenol, e.g., 2-cinnamylphenol, 4-cinnamyl phenol, 2-methoxy-4-cinnamyl-phenol, 2-cinnamyl-5-methoxy-quinol, etc.
