Abstract

The present invention relates to a vegetable oil which is or can be extracted from seeds and in which at least 12% of the triacylglycerol species that constitute the oil have the general formula SMS and at least 25% of the triacylglycerol species have the general formula SMM, wherein the formula gives from left to right the first, second and third fatty acid in the triacylglycerol and S represents a saturated fatty acid and M represents a monoenoic fatty acid. The invention further relates to a meal obtained as the remainder of the process for extracting the oil from seeds, as well as to the seeds containing the oil and the use thereof for the production of progeny plants having seeds which contain the oil.

Claims

1. Vegetable oil extractable from seeds comprising triacylglycerol species in which at least 12% of the triacylglycerol species of the oil have the general formula SMS and at least 25% of triacylglycerol species of the oil have the general formula SMM, wherein S represents a saturated fatty acid and M represents a monoenoic fatty acid.

2. An oil as claimed in claim 1, wherein the seeds are from plants selected from the group consisting of sunflower, soy bean, rape, and corn plants.

3. An oil as claimed in claim 1, further comprising at least 8% of triacylglycerol species having the general formula MMM.

4. An oil as claimed in claim 1, which has less than 8% saturated fatty acids at position sn-2 of the triacylglycerols that constitute the oil.

5. An oil as claimed in claim 4, which has less than 5% saturated fatty acids at position sn-2 of the triacylglycerols that constitute the oil.

6. An oil as claimed in claim 5, which has less than 3% saturated fatty acids at position sn-2 of the triacylglycerols that constitute the oil.

7. An oil as claimed in claim 1, wherein the total saturated fatty acid content is at least 25%.

8. An oil as claimed in claim 7, wherein the total saturated fatty acid content is at least 35%.

9. An oil as claimed in claim 8, wherein the total fatty acid content is at least 45%.

10. An oil as claimed in claim 1 having a palmitic acid content of at least 23% and an oleic acid content of at least 52%.

11. An oil as claimed in claim 1 having 20 to 25% triacylglycerols having the general formula SMS, 45 to 55% triacylglycerols having the general formula SMM and 20 to 25% triacylglycerols having the general formula MMM.

13. An oil as claimed in claim 1 obtainable by extracting sunflower seeds that have been mutagenized.

14. An oil as claimed in claim 13, wherein the seeds are mutagenized with X-rays at 300 cGy/min, beam 200 kV, 18 mA⁻

1 and dose 160 Gy.

15. An oil as claimed in claim 1, which oil is a sunflower oil.

16. An oil as claimed in claim 15 obtainable by extracting sunflower seeds of the mutant sunflower line IG-1297M deposited on Jan. 20, 1998 with the American Type Culture Collection under deposit accession number ATCC 209591.

17. An oil as claimed in claim 1, which is extracted and is for use at high temperature conditions.

18. An oil as claimed in claim 17, wherein the high temperature conditions constitute frying at temperatures of at least 100°

C.

19. An oil as claimed in claim 17, wherein the high temperature conditions constitute baking.

20. An oil as claimed in claim 17, wherein the high temperature conditions constitute cooking.

21. An oil as claimed in claim 17, wherein the high temperature conditions constitute roasting.

22. A sunflower oil as claimed in claim 17, wherein the high temperature conditions constitute heating by any means at temperatures of at least 100°

C.

23. An oil mixture comprising an oil as claimed in claim 1.

24. A meal obtained as the remainder of a process for extracting oil from seeds, wherein the oil that is extracted is an oil as claimed in claim 1.

25. A meal as claimed in claim 24, which meal originates from sunflower seeds.

26. Crushed seeds, which seeds in their uncrushed state contain a oil as claimed in claim 1.

27. Crushed seeds as claimed in claim 26, which seeds are sunflower seeds.

28. Seeds containing an oil as claimed in claim 1.

29. Seeds as claimed in claim 28, which seeds are sunflower seeds.

30. Sunflower seeds as claimed in claim 29, which seeds are obtainable from a mutant sunflower line.

31. Sunflower seeds as claimed in claim 30, wherein the mutant sunflower line is IG-1297M deposited on Jan. 20, 1998 with the American Type Culture Collection under deposit accession number ATCC 209591.

32. A method of obtaining vegetable oil, comprising crushing seeds as claimed in claim 28, and then extracting the oil therefrom.

33. A method of producing progeny plants having seeds which contain an oil according to claim 1, comprising growing plants from the seeds of claim 28.

34. An oil as claimed in claim 1 having more than 15% saturated fatty acids and less than 10% linoleic acid at high temperature conditions.

35. An oil as claimed in claim 34, wherein the high temperature conditions are selected from frying, baking, roasting, cooking.
