The preparation of pregelatinized starch and/or pregelatinized flour, including the steps of: providing an aqueous medium having a pH of −1.0 to 7.5; mixing starch and/or flour with the aqueous medium to form a starch composition having a pH of 2.0 to 7.9, wherein the starch composition has the aqueous medium as continuous phase and contains between 20 and 60 wt. %, expressed as percentage of dry matter on total weight of the starch composition, of particles of starch and/or flour; pregelatinizing the starch composition, wherein said composition is heated using a drum dryer, while rotating the drum, to form the pregelatinized starch and/or pregelatinized flour, wherein during the heating the starch composition is dried using the drum dryer; allowing the pregelatinized starch and/or pregelatinized flour to cool to a temperature of at most 80° C.; and storing the obtained pregelatinized starch and/or pregelatinized flour at a temperature of at most 60° C.

Disclosed in the present invention are a starch-embedded aroma substance microcapsule and a preparation method therefor. The method comprises: performing degreasing treatment on starch, gelatinizing the starch at high temperature, sequentially adding aroma substances having different molecular sizes into the starch paste, and compounding at high temperature; and finally, cooling, centrifuging, washing, and drying to obtain an aroma substance microcapsule. The total embedding rate of the aroma substances in the obtained microcapsule can reach 46.64%. The present invention is simple and convenient in process, and easy in condition control, does not need large special equipment, and has low cost and high efficiency.

This specification discloses thermally inhibited waxy cassava starches and edible compositions made therefrom. In one aspect edible compositions have improved creaminess compared to prior art starches, independent of starch usage level and the viscosity provided by the starch. In an embodiment the edible composition comprises between 0.1% and 35.0% by weight. In various embodiments the thermally inhibited waxy cassava starch has a peak viscosity of between about 100, and 2000 Brabender units or between 500 and 1500 Brabender Units.

A laminate comprising: a gas barrier layer (I) comprising a modified starch (A) having an average amylose content of 45% by mass or more and a water-soluble polymer (B); and a substrate (II) adjacent to the gas barrier layer (I), wherein the laminate exhibits a degree of biodegradation of 80% or more in a biodegradability test in accordance with ISO 14855-1.

The present invention relates to physically modified sago starch which exhibits an increased onset of gelatinization temperature and controlled viscosity development, yet retains significant hot and cold viscosity, the process of making such starch, and the use thereof. Such starches are useful in a variety of products, particularly as viscosifiers.

A colourless resistant starch is produced by a process comprising (i) suspending starch in a C2-C4 alcohol, in particular ethanol, in the presence of 0.01-3.0% (w/w) of acid based on the starch; (ii) heating the suspended starch at a temperature of 70-160° C., in particular 78-120° C., and (c) isolating the resulting product. The resulting starch has a resistant fraction of at least 20%.
