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-3protospacer 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.

The present application relates to improving the production yield of glucose to be prepared by using starch sugar as a raw material and using an Acidothermus sp. derived enzyme. The present application can replace an acid saccharification method, which produces a bitter taste through a hydrolysis reverse reaction, and, compared to a enzymatic saccharification method in which a conventional debranching enzyme is used, has an advantage of enabling costs to be reduced since a relatively high yield can be ensured by reducing side reactions of a saccharification reaction.

The present invention provides a nanocomposite hydrogel and a preparation method thereof, and relates to the field of nanocomposite materials. The nanocomposite hydrogel is prepared by mixing completely gelatinized short amylose with an aqueous gelatin solution having a mass concentration of 8%-14%, and then cooling. The present invention utilizes the nanoparticles formed by in-situ self-assembly of the short amylose in the aqueous gelatin solution as a reinforcing agent, and the nanoparticles are uniformly distributed in the hydrogel to form a stable crystallization system, such that the prepared nanocomposite hydrogel exhibits optimal mechanical properties in terms of viscoelasticity, hardness, compressive stress, etc. The preparation process of the present invention is green and environmentally friendly, simple and efficient, and can be widely applied to the fields of food, cosmetics and medicine.

The present invention relates to coated particles in which vegetable wax is provided on the surface of starch particles. The coated particles have an average particle diameter d.sub.1 of 0.5 to 20 ?m and a maximum particle diameter d.sub.2 being less than 30 ?m and less than 4.0 times the average particle diameter d.sub.1. The vegetable wax is contained in an amount of 0.5 to 10.0 wt % in the coated particles. Accordingly, particles having excellent feel characteristics and water repellency can be achieved with a natural material having excellent biodegradability. A method for producing coated particles includes: a step of preparing a dispersion that contains 1 to 20 wt % of starch particles; a step of adding vegetable wax to the dispersion and heating and cooling the mixture to precipitate the vegetable wax on the surface of the starch particles; and a step of subjecting this dispersion to solid-liquid separation to obtain coated particles as a solid.
