  • Publication number: 20100055293
    Abstract: The invention relates to a method for reducing the oil uptake of extruded and fried food products. The method of the invention comprises partially replacing said cook-up starch and/or instant starch in the ingredients of said food product by, or adding a hydrophobic starch. It has been found that the resulting food products have a remarkable lower tendency to take up oil when being fried.

  • Publication number: 20100029928
    Abstract: The invention relates to an emulsifier, a method for preparing said emulsifier, and to its use in various applications, primarily food and cosmetic applications. The invention also relates to the use of said emulsifier for the creation of an elastic, gelled foam. An emulsifier according to the invention is based on a starch which is enzymatically converted, using a specific type of enzyme, and modified in a specific esterification reaction.

  • Publication number: 20090130286
    Abstract: The invention relates to an instant noodle which can be rehydrated at a lower temperature and/or in a shorter period of time, while taste and mouthfeel of the noodle are at least as good as those of conventional instant noodles. The invention widens the scope of possibilities for supply and consumption of instant noodles, e.g. in vending machines, even or air dried instant noodles.

  • Patent number: 7282230
    Abstract: The invention relates to starch used in the baking-industry. Creams, (fruit-) fillings, toppings, glazes and other bakery products are often thickened by the inclusion of a certain amount of starch as binder, filling or thickening agent, for example providing gel-strength, viscosity, glaze, texture or creaminess to the cream or filling. Commonly used starches have insufficient stability to for example heat applied during baking. The invention provides a starch-containing filling or topping for a bakery product wherein said starch comprises a tuber or root starch containing less than about 5% amylose and use of such a filling or topping for improving a bakery product. Furthermore, the invention provides a heat-stable starch and bakery products comprising a heat-stable starch.

  • Patent number: 7157573
    Abstract: The invention relates to a process for preparing a hydrophobic starch, comprising etherification, esterification or amidation of a root or tuber starch comprising at least 95 wt. % of amylopectin, based on dry substance of the starch, or a derivative thereof, with a substituent comprising an alkyl chain having from 4–24 carbon atoms. The invention further relates to a hydrophobic starch obtainable by said process.

  • Patent number: 6899913
    Abstract: The invention relates to starch used in the food industry, more specifically to starch used in processed foodstuff that, at least in one processing step, is subject to heat and, or shear treatment. The invention provides use of modified starches and methods to use these in foodstuffs (soups, (dairy) desserts, sauces, creams, dressings, fillings and such), that, when used in preparing foodstuff that is subject to heat and/or shear treatment, provide said foodstuff with the so desired smooth, short textures and shiny appearance, even after prolonged treatment where use of other starches would render the product slimy, coarse or dull.

  • Patent number: 6890579
    Abstract: The invention relates to a gelling agent for production of a reversible gel. The gelling agent is a degraded root or tuber starch comprising at least 95 wt. % of amylopectin, based on dry substance of the starch. The gelling agent according to the invention is particularly suitable for use in food products.

  • Patent number: 6821548
    Abstract: The invention relates to starch used in the food-industry. The invention provides modified starch, and derivatives derived thereof, having improved salt-stability (salt-stable starch), use of such modified starch or derivatives derived from said starch in foodstuff, a method for providing salt-stability to foodstuff comprising use of such modified starch or derivatives derived from said starch and foodstuff comprising said modified starch or derivatives derived from said starch.

  • Patent number: 6749880
    Abstract: The invention relates to hydrocoloids that are used as thickening, binding, gelling or stabilising agents used in the food industry. The invention provides a starch composition, comprising a first fraction comprising cross-linked starch and at least a second fraction comprising copolymerised starch. Said composition is suitable for example to serve as gelatine replacement in foodstuff of varied nature, and is preferably suitable for use in foodstuff such as confectionery.

  • Publication number: 20040062837
    Abstract: The present invention pertains to the use of a degraded and cross linked starch in a food coating or batter composition for food products. Surprisingly, it has been found that by virtue of the use of this specific starch, the textural properties and in particular the crispiness of a coating on a food product are significantly improved.

  • Patent number: 6589293
    Abstract: The invention relates to the dehairing (depilating) of animal pelts, hides or skins, more specifically to depilatory paint and depilatory paint (depilation paint) thickener used in the depilation process in for example fellmongeries. The invention provides a depilatory paint thickener comprising a starch containing essentially only amylopectin molecules. Such thickener, is among other things, easily soluble in cold water; improves diffusion of chemicals (like sulfide or lime) throughout the skin; improves viscosity or resistance to shear of a paint, whereby less starch is needed to exert a similar effect; and increases the suspendability of a lime, allowing less time to be used which creates environmental advantages in waste disposal.
