摘要： A method for preparing an inhibited starch with improved warehouse storage stability is disclosed, wherein it comprises the steps of a) providing a slurry containing a native granular starch obtained from a starch containing raw material, b) adding at least one amino acid, or a combination of two or more of these, and at least one oxidant to the slurry with a view to inhibiting the granular starch, c) adding at least one organic acid or a bisulfite to the slurry with a view to eliminating residual reactant chemicals, off-tastes, and undesired smell, and d) adding at least one antioxidant to the slurry with a view to stabilizing the achieved inhibition of the starch during warehouse storage, as well as an inhibited starch with improved warehouse storage stability prepared with said method, use of said inhibited starch as an ingredient in a food product, and a food product containing said inhibited starch.

摘要： A method for the preparation of a food grade coagulated potato protein concentrate is disclosed, wherein it comprises the steps of a) separating fibers and starch from a potato pulp, wherein a potato fruit juice containing potato protein is obtained, b) coagulating the potato protein in the potato fruit juice by adjusting the pH to an acidic value and by heating, wherein a coagulated potato protein slurry containing particles of coagulated potato protein is obtained, c) reducing the total glycoalkaloid content in the coagulated potato protein slurry to less than 150 mg/kg protein concentrate, and d) actively reducing the particle size of the of potato protein particles by physical means in such a way that a coagulated potato protein concentrate is obtained in which 90% of said particles have a particle size of less than 55 μm, as well as a food grade coagulated potato protein concentrate produced with said method, use of the food grade coagulated potato protein concentrate in a food product, and a food product for human use comprising said food grade coagulated potato protein product.

摘要： Amylopectin potato starch with improved stability against retro-gradation and improved freeze and thaw stability, wherein it contains more than 99% amylopectin, preferably 100% amylopectin, is disclosed, as well as a method for the production of a potato (Solanum tuberosum) containing said amylopectin potato starch, wherein said method involves homology-directed mutagenesis using CRISPR/nuclease technology and comprises the following steps: a) provision of potato cells or potato tissue containing potato cells, b) introduction into the nuclei of said potato cells of one or more CRISPR/nuclease complexes each comprising a specific targeting ribonucleotide sequence which is fully or essentially homologous to a target nucleotide sequence located in a DNA sequence immediately upstream of a PAM (5′-NGG-3′protospacer adjacent motif) in a gene coding for a GBSS enzyme and optionally also in a gene coding for an SSII enzyme and/or in a gene coding for an SSIII enzyme, wherein said mutagenesis takes place in one or more alleles of the potato genome, wherein when said targeting ribonucleotide sequence identifies the complementary strand of the target nucleotide sequence, said one or more CRISPR/nuclease complexes cut(s) said DNA sequence, leading to a subsequent complete lack of the ability of the potato to produce a functional GBSSI enzyme, optionally also a functional SSII and/or SSIII enzyme, c) wherein step b) optionally is repeated until the potato lacks the ability to produce said functional GBSSI enzyme, optionally also a functional SSII and/or SSIII enzyme, in all of the alleles, preferably 3 times, a potato obtained by said method, a method for the production of said amylopection potato starch from said potato, and different uses of said amylopectin potato starch. a gene coding for an SSII enzyme and/or in a gene coding lor an SSIII enzyme, wherein said mutagenesis lakes place in one or more alleles of the potato genome, wherein when said targeting ribonucleotide sequence identifies the complementary strand of the target nucleotide sequence, said one or more CRISPR/nuclease complexes cut(s) said DNA sequence, leading to a subsequent complete lack of the ability of the potato to produce a functional GBSSI enzyme, optionally also a functional SSII and/or SSIII enzyme, c) wherein step b) optionally is repeated until the potato lacks the ability to produce said functional GBSSI enzyme, optionally also a functional SSII and/or SSIII enzyme, in all of the alleles, preferably 3 times, a potato obtained by said method, a method for the production of said amylopection potato starch from said potato, and different uses of said amylopectin potato starch.
