    • An enzyme resistant starch type III which has a melting point or endothermic peak of at least about 140.degree. C. as determined by differential scanning calorimetry (DSC) is produced in yields of at least about 25% by weight, based upon the weight of the original starch ingredient. A gelatinization stage, nucleation/propagation stage, and preferably a heat-treatment stage are used to produce reduced calorie starch-based compositions which contain the enzyme resistant starch type III. The enzyme resistant starch is produced using crystal nucleation and propagation temperatures which avoid substantial production of lower melting amylopectin crystals, lower melting amylose crystals, and lower melting amylose-lipid complexes. The nucleating temperature used is above the melting point of amylopectin crystals. The propagating temperature used is above the melting point of any amylose-lipid complexes but below the melting point of the enzyme resistant starch. Starch-based compositions comprising the high-melting RS type III of the present invention exhibit unexpectedly superior baking characteristics, such as cookie spread, golden brown color, pleasant aroma, and surface cracking which are comparable to those achieved with conventional wheat flour. The high melting point of the enzyme resistant starch, as measured by DSC, permits its use in baked good formulations without substantial loss of enzyme resistance upon baking.
    • 以差示扫描量热法(DSC)测定的具有至少约140℃的熔点或吸热峰的抗酶淀粉III产生的产率为至少约25重量%,基于 原淀粉成分。 使用糊化阶段,成核/繁殖阶段,优选热处理阶段来生产含有III型抗酶淀粉的低热量淀粉基组合物。 使用晶体成核和传播温度产生耐酶淀粉,其避免了显着产生较低熔点的支链淀粉晶体,较低熔点的直链淀粉晶体和较低熔点的直链淀粉 - 脂质复合物。 使用的成核温度高于支链淀粉晶体的熔点。 所用的传播温度高于任何直链淀粉 - 脂质复合物的熔点,但低于耐酶淀粉的熔点。 包含本发明的高熔点RS型III的淀粉基组合物显示出与传统小麦粉所达到的相当的意想不到的优异的烘烤特性,例如饼干蔓延,金棕色,宜人的香气和表面裂纹。 通过DSC测量,耐酶淀粉的高熔点允许其在烘焙良好配方中使用,而在烘烤时不会显着降低酶抗性。

    • Baked, wheat-based, chip-like snacks having a plurality of surface bubbles comprising air pockets extending both above and below the substantially unleavened, adjacent portions of the snack are obtained with a pregelatinized waxy starch, pregelatinized potato starch, and optional modified potato starch. The pregelatinized potato starch produces a crisp, crunchy texture in the baked snack. The pregelatinized waxy starch is at least substantially uniformly hydrated prior to baking for producing bubbles during baking and for retaining the bubbles. The pregelatinized potato starch is at least substantially uniformly hydrated prior to baking for controlling bubbling caused by the pregelatinized waxy starch and for controlling texture of the bubbled and unbubbled portions of the snack chips. Use of the gluten-containing wheat flour and bubble-forming amounts of the pregelatinized waxy starch provides for the production of a cohesive, non-sticky, extensible, continuously machinable dough. A modified potato starch which is activated during baking may be used to enhance surface bubbling and crispiness of the bubbled portions and unbubbled portions. The pregelatinized waxy maize starch may be used in an amount of from about 3% by weight to about 20% by weight, and the pregelatinized potato starch may be used in an amount of from about 1.5% by weight to about 20% by weight, each based upon the weight of the wheat flour. The weight ratio of the amount of the pregelatinized waxy starch to the total amount of the potato starches may be from about 0.45:1 to about 1:1. Non-fermented and fermented reduced fat, low-fat, and no-fat baked products, as well as full-fatted non-fermented and fermented baked products, may be produced with a bubbled surface, and a crispy, crunchy, non-mealy, chip-like texture, but with a wheat cracker flavor.

    • Low moisture content comestibles having reduced water regain or increased tolerance to moisture are produced by enzymatically treating a farinaceous material with an enzyme composition comprising pentosanase or beta-glucanase, or mixtures thereof to reduce its net-work forming swellable water-soluble hemicellulose content. The hydrolysis of the water-soluble pentosans, beta-glucans or mixtures thereof is conducted so that a substantial portion of the hydrolysis product has a linear or backbone degree of polymerization of less than about 100, more suitably less than about 75, preferably less than about 50, most preferably less than 17. In addition, the hydrolysis is conducted so as to minimize the production of mono and/or di-saccharides. The low moisture content comestible products include low moisture content baked good such as cookies, crackers, and biscuits, farinaceous pet snacks, plant protein extracts, hot cereals, ready-to-eat cereals, low calorie flours and low calorie flour fractions. The enzyme compositions which are used are preferably substantially completely free of proteases and amylases so as to avoid reducing the functionality of proteins and starch, respectively. The comestible products have a moisture content of less than about 20 percent by weight. Hemicellulose hydrolyzates may also be produced for incorporation into comestibles.
