Abstract: The use of tocopherol mixtures for stabilizing carotinoid-containing biomasses and biomass preparations, more particularly astaxanthin-containing biomasses and biomass preparations, and to a process for stabilizing such biomasses and biomass preparations. The tocopherol mixture used preferably contains ?- and ?- and ?- and ?-tocopherol. The invention also relates to carotinoid-containing biomass containing 0.1 to 10% by weight of tocopherol mixtures, based on the weight of the dry biomass.

Abstract: A process for making synthetic triglycerides involving: (a) providing a reaction component selected from the group consisting of glycerol, a triglyceride, and mixtures thereof; (b) providing a fatty acid mixture containing at least 50% by weight, based on the weight of the fatty acid mixture, of conjugated linoleic acid; (c) providing an inert gas atmosphere; (d) combining the reaction component with the fatty acid mixture, in the inert atmosphere, to form a reaction mixture; and (e) heating the reaction mixture to a temperature of from 180 to 240° C., at a heating rate of from 0.5 to 3 K per minute, thus forming the synthetic triglyceride.

Abstract: Wheat protein hydrolyzates are produced by hydrolyzing a wheat protein-containing starting material, preferably a wheat protein isolate having a protein content of 70 to 90%, with a proteinase such as a serine protease at a pH of 2 to 5, then with a proteinase at a pH of 8 to 10 and finally with a peptidase at a pH of 6 to 7. The hydrolysis steps are preferably at a temperature below the gelatinization temperature of carbohydrate present in the protein. Each hydrolysis may be carried out for 1 to 24 hours at a temperature of 40 to 70.degree. C. To reduce traces of unwanted color formers, an adsorbent such as silica gel, aluminum oxide or activated carbon may be present during the hydrolysis steps. Aqueous wheat protein hydrolyzate solutions are obtained and, if required, may be concentrated, for example using falling film evaporators. The hydrolyzates have an average molecular weight in the range of 100 to 30,000, preferably 2,000 to 5,000, and a solids content of around 5 to 50%.

Abstract: Described is the chemical hydrolysis of partial hydrolysates obtained by the enzymatic decomposition, in aqueous conditions in the presence of alkaline-earth oxides or hydroxides, of protein-containing raw materials containing chromium. This enables protein hydrolysates with a particularly low chromium content to be obtained which are stable to turbidity during storage. The chemical hydrolysis must be carried out in the presence of compounds selected from the alkaline-earth oxides and hydroxides, and within the critical pH range of 11 to 13.

Abstract: An adhesive composition comprising a plurality of selectively hydrogenated block copolymers, each of said block copolymers comprising at least one polymeric block containing predominantly monoalkenyl aromatic hydrocarbon monomer units and at least one polymeric block containing predominantly conjugated diolefin monomer units, at least one of which block copolymers is carboxylated and at least one of which block copolymers is not carboxylated and laminated structures comprising a plurality of polymeric layers tied together with said adhesive composition. The adhesive composition contains a relatively minor amount of carboxyl groups, on average, per polymer chain in the composition and is particularly useful in the preparation of laminated structures via coextrusion or similar processes, wherein the various layers are brought together in the molten phase while in motion, when one or more layers in the laminated structure comprises a polar group reactive with the carboxyl groups.

Abstract: A thermoplastic blend with the ability to absorb less than 40% of an oil, and having a superior tensile strength comprises about 80 to about 20 phr of an elastomeric block copolymer having the general configuration A-B-A, wherein the B block is a butadiene hydrocarbon block consisting of about 35 to about 55 mole percent of condensed butadiene units in the 1,2 configuration, and about 20 to about 80 phr of a block copolymer having the general configuration A-B-A, wherein the B block is a hydrogenated butadiene hydrocarbon block consisting of about 18 to about 34 mole percent of condensed butadiene units in the 1,2 configuration.

Abstract: A reliable method for testing the performance of detergent compositions, particularly from the standpoint of the redeposition of soils on fabrics during the laundry wash cycle, which comprises subjecting a clean control fabric swatch to multiple washings, each washing conducted in a solution of the detergent composition and in the presence of one or more pre-soiled fabric swatches, and then analyzing the control swatch for soil content, for example, by light reflectance or radiotracer methods.

Abstract: Alkoxyalkanols are oxidized to the corresponding alkoxyalkanoic acids by contacting the alkanols with oxygen in the presence of a catalyst comprising platinum supported on a macroreticular cross-linked polystyrene/divinylbenzene resin. Enhanced rates are obtained.

Abstract: A terminal --CH.sub.2 OH moiety is selectively cleaved from an alkoxyalkanol at elevated temperatures, in the optional presence of water, over a catalytically effective amount of heterogeneous nickel.

Abstract: Polyester molding compositions which contain an unsaturated polyester and an additional monomer for curing the polyester are improved by addition of a block copolymer which is modified with an unsaturated polyester. The block copolymer is an unsaturated block copolymer of a monoalkenyl aromatic hydrocarbon and a conjugated diene. The block copolymer is preferably produced by polymerizing styrene-butadiene diblock copolymer arms and coupling the arms with a difunctional coupling agent.
