  • Publication number: 20130230622
    Abstract: A method of manufacturing an edible product, a laminated dough composition and an edible product are provided. The method includes mixing ingredients including starch, gluten, a plasticizer, fat and leavening into a pastry dough composition. A flavored fat composition is prepared by mixing ingredients comprising fat, at least one flavor additive and at least one filling. The flavored fat composition is then applied to a surface of the pastry dough composition. Both compositions are folded and sheeted to form a laminated dough. The laminated dough is then formed into pieces, which are proofed and then baked. A laminated dough composition, and an edible product itself, is provided that comprises a plurality of layers of a flavored fat interposed between a plurality of layers of a pastry dough, the pastry dough composition comprising starch, gluten, a plasticizer, fat and leavening; the flavored fat composition comprising fat, at least one flavor additive and at least one filling.

  • Patent number: 8496987
    Abstract: A stable trans fat free emulsifier composition is provided that may have other functional ingredients incorporated to form a base for a flour-based dough preparation to hold the ingredients together. A glyceride emulsifier is heated above its melting point and blended with a non-hydrogenated vegetable oil, or a quantity of glyceride emulsifier is blended with non-hydrogenated vegetable oil and the mixture then heated to a temperature above its melting point. The ratio of emulsifier to vegetable oil is selected to cause the composition, upon cooling, to form a solid plastic mass. The hardness value of the plastic mass is within a range especially applicable to bakery dough applications.

  • Publication number: 20120045544
    Abstract: The present invention relates a frozen non-leavened farinaceous dough that can be leavened under ambient conditions before being baked, fried and/or boiled to produce a ready-to-eat foodstuff. More particularly, the invention provides a frozen non-leavened farinaceous dough containing at 103 cells/g viable cells of an S. bayanus strain. The dough product according to the invention offers the advantage that the time window within which the leavened dough can be prepared for consumption is very broad, i.e. several hours. Another aspect of the present invention relates to a method of preparing a ready-to-eat cooked leavened dough product, said method comprising the steps of: ?thawing and leavening a frozen non-leavened dough as described above by keeping it under ambient temperature for 6-24 hours to obtain a leavened dough having a specific volume of at least 2.0 ml/g; and ?baking, frying and/or boiling the leavened dough.

  • Publication number: 20060286212
    Abstract: New caramel compositions suitable for use with crisp bases such as cookies and crackers are provided. The new caramel compositions are able be packaged over long periods of storage in direct contact with a crisp base comprised of a cookie or cracker without adversely affecting the texture of either the crisp base or the caramel. They comprise a cooked mixture prepared from: liquid triglyceride, monosaccharide, disaccharide, polyol, milk solids, and emulsifier. The caramel exhibits an Aw of less than 0.42. Processing entails: mixing ingredients comprising liquid triglyceride, monosaccharide, disaccharide, polyol, milk solids, and emulsifier in a heating vessel; heating the ingredients to form a uniform heated mixture while scraping the vessel during heating to prevent scorching; and increasing the heat to boil the ingredients to a temperature and for a time to achieve caramelization.

  • Patent number: 6905720
    Abstract: A savory, smooth-textured, bakeable and shelf-stable product is prepared as a three-phase formulation, including an aqueous liquid phase, a dispersed fat phase and a solids phase, preferably containing cheese in significant proportion. The liquid phase is present in sufficient quantity to suspend and disperse the fat and solids phases. The dispersed fat must have sufficiently small droplet size raise the viscosity for this phase sufficiently to result in a creamy texture for the final product. The savory flavor ingredients are present as undissolved solids of sufficiently small particle size to provide the proper flavor release for the flavor and a texture consistent with the savory flavor. Preferred cheese products will have a lubricous, slippery, smooth mouthfeel and a flavor release that endures until the palate is essentially clean. The product can be applied to unbaked doughs prior to baking and retain their desired properties after baking.

  • Patent number: 6461657
    Abstract: A process is provided for making a prepared mustard product having reduced tendency for syneresis. A slurry is prepared to contain ground mustard seed, water, vinegar, salt and an amount of type JMJ pectin effective to reduce the tendency toward syneresis, e.g., from about 0.1 to 0.5% by weight. The resulting slurry is then homogenized sufficiently to provide a viscosity of from 7,000 to 25,000 centipoises after setting. Upon packaging, the product will have less tendency to suffer separation of water to form a free phase.
