Abstract:
2003541 METHOD OF PREPARING REDUCED FAT FOODS A food formulation having a reduced level of fat and/or oil is provided. The food formulation is a mixture of a foodstuff and a fragmented, amylopectin starch hydrolysate as a replacement for at least a substantial portion of the fat and/or oil of said food formulation. The fragmented starch hydrolysate is capable of forming an aqueous dispersion at about 20% hydrolysate solids exhibiting a yield stress of from about 100 to about 1,500 pascals. Also provided is a method of formulating a food containing a fat and/or oil ingredient comprising replacing at least a portion of said fat and/or oil ingredient with the fragmented, amylopectin starch hydrolysate. Examples of food formulations include those for margarine, salad dressings (pourable and spoonable), frostings, and frozen novelties.
Abstract:
Water-absorbent, starch copolymerizates are prepared by copolymerizing an ethylenically unsaturated starch with other ethylenically unsaturated monomers which contain water-attractant groups or precursors or waterattractant groups. The water-absorbent starch copolymerizates may be easily prepared into the desired configuration for a particular end-use or combined with other substrates or carriers. The unpolymerized starch and monomers or precursors thereof may be applied or incorporated into a suitable carrier or substrate (e.g., cellulosio materials such as textiles, papers, etc.) and copolymerized in situ to provide a composite article or unitary construction with the water-absorbent starch copolymerizate permenently bonded or affixed thereto.
Abstract:
Preformed, homogeneous, non-linear starch copolymerizate articles may be prepared by copolymerizing a preformed, homogeneous mixture of water, ethylenically unsaturated starch and ethylenically unsaturated monomers to provide a labyrinth of copolymerized starch chains inter-connected with each other by the copolymerized monomeric units. The invention is particularly suitable for preparing high-binder, aqueous coating compositions which may be applied to a variety of substrates and subsequently copolymerized with polymerization initiating systems. Improved water- and detergent-resistance may be obtained by incorporating film-forming additives, cross-linking reagents or polyunsaturated compounds into the copolymerizable starch composition.
