摘要:
The present invention relates to genetically modified plant cells and plants, and to processes for the production of genetically modified plant cells and plants which have an increased activity of a protein having the activity of a starch synthase Il and an increased activity of a protein having the activity of a glucan-water dikinase. Plants of this type synthesize starches having increased hot water swelling power. The present invention likewise relates to starches having increased hot water swelling power, and to processes for their production.

Stärken mit erhöhtem Heißwasser Quellvermögen, sowie Verfahren zu deren Herstellung sind ebenfalls Gegenstand der vorliegenden Erfindung.
摘要:
A method has been discovered to produce a resistant starch product that retains the same cooking quality as found in untreated rice starch or flour, but has a higher percentage of starch resistant to α-amylase digestion. This method uses a debranching enzyme, e.g., pullulanase, to digest the starch, but does not require pre-treating the starch source prior to enzymatic treatment. This method produced resistant starch from low amylose starches, rice starch (24%) and rice flour (20%). Fig.9 illustrates the results of differential scanning calorimetry of non-gelatinized rice flour that was not stored before being incubated with the enzyme pullulanase for 2 hr (NGNS2hr), 4hr (NGNS4hr), or 16 hr (NGNS16hr).

A process of producing starch from plant material is provided which involves adding extraneous protein to the plant material. This produces a network of protein. The starch is isolated from the protein network/plant material mixture.
摘要:
The subject of the invention is a method for preparing fine-granuled starch from kernels of oats or rice. In the method, the kernels are ground and the starch is separated from the starch containing fraction obtained by the milling. An essential feature of the invention is that a suspension of the said fraction or of starch separated from it is treated with a surface-active agent or a lipolytic enzyme for disintegrating compound granules or aggregates of starch granules. Except the particle size, also functional properties of starch are affected. Disintegration of compound granules is enhanced by alkaline conditions and by mixing of the suspension. The fine-granuled starch obtained can be applied in foods and, for instance, for biodegradable plastics and for surface treatment agents. The invention can be included as a part of an integrated fractionation process, in which, in addition to starch, an oil fraction, an enriched fibre fraction, and a surplus fraction suitable for feed, are obtained.
摘要:
Hydrocolloidal compositions recovered from the liquid fraction obtained by subjecting oat or barley substrates to a heat-shearing treatment are rich in soluble fiber, principally β-glucan, and are substantially free of insoluble fiber particles. Dispersions of these compositions are smooth in texture and are useful as texturizers and nutritional substitutes for dairy products in food compositions.
摘要:
The invention relates to plant glycogen which is polysaccharides being derived from rice and containing a high molecular weight group whose weight average molecular weight is 5.00 to 7.60 millions and a low molecular weight group whose weight average molecular weight is 0.30 to 1.10 millions, said glycogen consisting essentially of a glucose polymer, being easily dissolved in cold water and hot water, and being rendered viscous when water in an amount of 25 to 200 % is added, as well as to a process for producing said plant glycogen, which comprises immersing finely ground rice in water or a water-containing solvent, subjecting it to a solid-liquid separation to give an extract, heating it to remove thermally precipitated solids and proteins, adding the resulting liquid layer to an organic solvent, and recovering the resulting white precipitates, followed by purification if necessary.
