Abstract: FIELD: organic syntheses. SUBSTANCE: aqueous mobile medium is first dehydrated and heated to form essentially anhydrous melt capable to be agitated. The aqueous mobile medium contains dissolved substance selected from the group including dimethyloldimethylhydantoin, hydantoin reagent, formaldehyde source, or any combination of indicated components; and optionally a catalyst. Molten system is further prepared by adding to apt-to-agitation melt a reactive mixture containing the same or another hydantoin reagent, essentially anhydrous the same or another formaldehyde source, or their combination; and optionally the same or another catalyst. Finally, molten system contains at least one hydantoin reagent and at least one dehydrated formaldehyde source or essentially anhydrous formaldehyde source. At least one hydantoin reagent in molten system is allowed to react with at least one dehydrated or essentially anhydrous formaldehyde source, which reaction is accompanied by withdrawal of water and results in formation of anhydrous molten methylolhydantoin which is further solidified. Alternative version of invention consists in preparing solid anhydrous methylolhydantoin by reaction of reaction mixture containing the same or another hydantoin reagent, essentially anhydrous the same or another formaldehyde source, or their combination optionally in presence of the same or another catalyst in the above-indicated apt-to-agitation medium containing at least one hydantoin reagent and at least one formaldehyde source or essentially anhydrous formaldehyde reagent. Reaction is carried out at heating to a temperature at least equal to melting temperature of methylolhydantoin, while removing essentially all water, to form molten methylolhydantoin. The two methods may be performed both in periodical and semicontinuous modes. EFFECT: enhanced efficiency of preparation procedure. 23 cl

Granted: 1998-02-27
Abstract: FIELD: food-processing and confectionery industry. SUBSTANCE: method involves preparing sugar fondant; mixing it with portion of receipt butter; whipping with remaining quantity of butter; mixing with dry milk, flavor and aromatizing additives; molding candy centers; holding prior to glazing. Upon mixing with dry milk, alcohol with ethyl strength of 94-96 deg is added into candy mass in an amount of 3.5-8.5% of total weight of candy mass. Candy mass is initially mixed with alcohol, then with groats extrusion product. Alcohol facilitates thinning of candy mass. Ground groats extrusion product uniformly distributed in candy mass imparts rheological properties to candy mass making it similar to dough used for producing meat pockets and improving molding process. The process is terminated with insertion of filler into molded candy centers. Holding time prior to glazing is reduced by four times due to evaporation of introduced alcohol from surface layers, which become stale at far faster time.
