Abstract: A novel color-stable food product containing anthocyanin or anthocyanidin pigments and containing bio-available vitamin C. The novel food may be produced as the product of an improved food production process wherein the improvement comprises providing the bioavailable vitamin C in the form of an enolic OH substituted derivative of ascorbic acid selected from the group consisting of inorganic esters, aliphatic or alicyclic esters, and O-alkyl ethers of ascorbic acid.

Abstract: A mobile aerial support system for use in support of ground operations comprises a helicopter and a mobile helicopter pad. The mobile pad consists of an open, drop-bed trailer adapted to bear and restrain the helicopter, a tractor adapted to pull the trailer with the helicopter mounted thereon, a four wheel drive vehicle adapted to be carried on the trailer adjacent said helicopter, an enclosure mounted on the trailer and tractor containing a complete workshop for maintenance and repair of the helicopter as well as a complete inventory of spare parts and accessories for the helicopter.

Abstract: A m-Menthenone, 2-Methyl-4-siopropylcyclohex-3-en-1-one, (MICO) which possesses a cooling fragrance, is described. This compound or any one of a family of alkyl substituted analogs may be synthesized by a Lewis acid catalyzed rearrangement of 2,3-epoxycarane or its theoretically obtainable alky, substituted analogs.

Abstract: Tea compositions having improved color and flavor are produced by adding water-soluble aluminum salt(s) to the compositions or precursors during any stage of the manufacture up to the point of consumption, or even by coating or spraying the tea leaves prior to plucking and processing. Enhanced characteristics obtained as a result of this addition include increased redness and brightness and improved flavor.

Abstract: Method for producing a free-flowing orange juice powder having improved flavor including (a) providing an aqueous slurry having up to about 65% solids, about 50-85% of which is orange juice with the balance being a food grade, water-dispersible or water-soluble drying aid and (b) cocurrently spray drying the slurry to a powder having an average moisture content of less than about 4% under carefully controlled drying conditions. The dryer inlet and outlet air temperatures are maintained at about 220.degree.-300.degree. F and about 145.degree.-205.degree. F, respectively. The spray dryer nozzle pressure is suitably less than about 5,000 psig with the slurry feed rate through each nozzle being less than about 45 gph. The interior walls of the spray dryer are maintained at a temperature of less than the sticky point temperature of the dried powder, preferably less than about 135.degree. F.

Abstract: Method for preparing a 3-deoxy-5-hydroxyanthocyanidin salt having a 4' and/or 7 OH substituent from a corresponding acylated flavanone, by (1) reducing the acylated flavanone in a solvent medium by reaction with an alkali borohydride to form a corresponding flavan not having an OH substituent at the 4 position, and (2) oxidizing the flavan or an acylated or hydrolyzed derivative of the flavan in an organic solvent medium by reaction with a halogenated benzoquinone in the presence of a strong acid and water. Suitable acylated flavanones include acetylated natural flavanones, especially acetylated naringenin and hesperetin.

Abstract: A troweling machine having a variable troweling diameter may be constructed by providing such a machine with adjustable length spider arms, an adjustable circumference guard ring, an adjustable length guard ring stabilizer arm and any combination of two of such adjustable features. A universal blade mounting adaptor allows the machine to accept blades of various sized as well as various specific attachment arrangements. A pivotal mount for the guard ring permits it to be swung upwardly from its normal horizontal position.

Abstract: Nitrilotriacetonitrile (NTN) is produced in high yeilds from hydrogen cyanide, formaldehyde and ammonia, or its equivalent as an ammonium salt of a strong acid, by utilization of a critical two-stage reaction sequence within a narrow dilution ratio and temperature range. The reaction sequence steps provide for a first mixture to be prepared comprising a mixture of the formaldehyde and ammonia. No external adjustment of the pH of this mixture is permitted. A second mixture is prepared comprised of the HCN in an aqueous solution and a strong mineral acid such as sulfuric acid for adjusting the pH of the mixture to about 1 or less. NTN is produced by combining the mixtures at a temperature of from about 55.degree. C. to about 70.degree. C. either by adding the formaldehyde/ammonia solution to the HCN/acid solution or vice versa. The ratios and dilution of the reactants is critical for good yields.
