Patent ID: 8252974

Claim:
A method of obtaining a heat-processed, potato tuber food that has a low level of acrylamide, comprising: (A) storing potato tubers at low temperatures; (B) selecting a tuber with a low concentration of reducing sugars; and (C) producing a food for heat-processing from the selected tuber, wherein (i) the heat-processed potato tuber food has a low concentration of acrylamide compared to a potato tuber food which is produced from a tuber that has a higher concentration of reducing sugars, (ii) the potato tuber with the low concentration of reducing sugars is grown from a potato plant that has stably integrated into its genome at least one desired polynucleotide that alters the expression of at least two of R1, phosphorylase-L, and invertase inhibitor genes, and (iii) the desired polynucleotide consists essentially of: (a) nucleic acid sequences that are native to the transformed potato plant, native to a plant from the same species as the transformed potato plant, or native to a plant that is sexually interfertile with the transformed potato plant; wherein (b) the desired polynucleotide does not contain foreign DNA that is not from the transformed potato plant species or a plant that is sexually compatible with the transformed potato plant species.
