  • Publication number: 20150342200
    Abstract: In the present invention, it has been an object to obtain a physical property improvement agent for improving the various physical properties of wheat-based food such as bread, wheat-flour baked sweets, and noodles. By using a water-soluble pea polysaccharide, it is possible to obtain a physical property-improving effect in wheat-based food such as bread, wheat-flour baked sweets, and noodles. In bread and wheat-flour baked sweets, while changes in the mouthfeel caused by aging of starch are suppressed, the workability is enhanced by improving the spreadability of the dough, furthermore, the volume after baking is increased, and mouthfeel with good crispness and meltability in the mouth is obtained. In noodles, it is possible to suppress aging when braised noodles are stored at room temperature or with refrigerating.

  • Publication number: 20150322175
    Abstract: The object of the present invention is to provide a dispersion stabilizer that can minimize coagulated precipitation of a protein under acidic conditions, especially in the pH range of around pH 5 which is closer to neutrality than the range around the isoelectric point of the protein. It is possible to stabilize dispersion of protein particles around pH 5, and thus prepare an acidic protein food, by using a legume seed polysaccharide esterified with a succinic acid derivative having a hydrocarbon chain bonded to the 2-position carbon of succinic acid or succinic acid. The hydrocarbon chain of the succinic acid derivative preferably has 2 to 18 carbon atoms, and is most preferably an octenyl group. The esterified legume seed polysaccharides also have high emulsifying ability.
