摘要:
An enzyme resistant starch type III having a melting point or endothermic peak of at least about 140° 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 high melting point of the enzyme resistant starch permits its use in baked good formulations without substantial loss of enzyme resistance upon baking. A gelatinized, starch-based bulking agent having at least 30% by weight of the enzyme-resistant starch may be used in bar-type, extruded, sheeted, or rotary molded food products. The melting enthalpy of the bulking agent may be from about 0.5 to about 4 Joules/g and its water-holding capacity may be less than 3 grams.

摘要:
Extruded, directly expanded, high fiber reduced calorie food products, such as a ready-to-eat (RTE) cereal or sweet or savory snack, are produced at high production rates without substantial loss of extrusion functionality and extrudability by replacing a substantial portion of at least one flour with a gelatinized, enzyme-resistant starch type III ingredient or bulking agent as a reduced-calorie, high fiber flour replacer. The resistant starch type III ingredient or bulking agent contains an enzyme-resistant starch type III having a melting point with an endothermic peak temperature of at least about 140° C., and may have a water-holding capacity of less than 3 grams water per gram of the starch-based bulking agent. The total dietary fiber retention of the gelatinized, starch-based bulking agent may be at least about 90% by weight after extrusion using a die temperature of least about 100° C., and a die pressure of at least about 150 psig.
摘要:
A stabilized bran component and a stabilized whole grain flour containing the component are produced by subjecting a bran-enriched coarse fraction which contains bran, germ and starch to grinding or milling to reduce grittiness of the coarse fraction without substantially damaging the starch due to abrasion. The coarse fraction may be stabilized by heating to substantially reduce the lipase and lipoxygenase activity of the coarse fraction without substantial gelatinization of the starch. High levels of natural antioxidants and vitamins are retained while avoiding substantial acrylamide formation during the stabilization. The stabilized coarse fraction or stabilized bran component may be combined with a fine fraction which contains predominantly endosperm to obtain a stabilized whole grain flour. The stabilized whole grain flours and the stabilized bran component exhibit extended shelf life and may be used for making baked goods, such as cookies, with desirable oven spread, and a non-gritty mouthfeel.
