They are useful intermediates for preparing herbicidal compounds.

Abstract: The present invention is directed to a method for manufacture of an imitation cheese using an acid casein or rennet casein which has been treated to remove stale flavors in accordance with the invention. In the method of the invention for removing stale flavors from acid casein or rennet casein, an initial mixture of dried casein and water is provided. The casein is maintained in suspension in the water for a period of time sufficient to substantially hydrate the casein. While the casein is maintained in suspension, water is removed from the initial mixture. At the same time that water is removed from the mixture, fresh makeup water is added to the mixture at substantially the same level that the water is removed from the mixture. The casein is then recovered from the mixture by a suitable process, such as by centrifugation.

Abstract: A fat-reduced, edible, water-in-oil spread is produced by heating a fat which is normally solid at room temperature so as to melt a substantial proportion of less thermally stable crystals in the fat; homogeneously admixing sufficient water to the heated fat to reduce the proportion of fat in the resulting admixture; cooling the admixture to crystallize a substantial proportion of the uncrystallized fat and produce a pumpable plastic mass; and subjecting the pumpable plastic mass to cutting and mixing in a turbine-like comminuting device while limiting the temperature rise of the plastic mass.

Abstract: A method for reducing residual numbness experienced by dental and medical patients infiltration injection in the gums or mouth region with anaesthetic. After a dental or medical procedure, such as filling or extracting a tooth, a quantity of niacin is placed against the gum or other area where the anaesthetic was initially injected. The niacin enters the blood vessel walls to expand the blood vessels, thus to effect an increased flow of blood for more rapid transport of anaesthetic from the numbed area.

Abstract: The tendency of herbicidal pyridinedicarbothioates to crystallize and thus to partially lose herbicidal activity when formulated into granules is reduced by including in the granules a small, effective amount of a diester of an alkylene dicarboxylic acid.

Abstract: The invention relates to a process for the treatment of a non-liquid food product for assuring its microbial decontamination. This process, applicable to hydrated products containing at least 20% water, comprises depositing on the surface of the hydrated product a preparation called an LP system comprising a mixture of the enzyme lactoperoxidase, a thiocyanate and an oxygen donor. The depositing may in particular be carried out by pulverizing or immersion in a bath. The treatment according to the invention preserves the product against most of the pathogenic or saprophytic germs susceptible of developing on these products, in particular bacteria of the genus Listeria, and in the absence of decomposition of the product and with no risk for the consumer.
