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.

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.
