Seed Types and Oil
Other types of pumpkin seed oil are also marketed worldwide. International producers use white seeds with shells and this produces a cheaper white oil. New producers of seeds are located in China and India.
An analysis of the oil extracted from the seeds of each of twelve cultivars of C. maxima yielded the following ranges for the percentage of several fatty acids:
| n:unsat | Fatty acid name | Percentage range |
|---|---|---|
| (14:0) | Myristic acid | 0.09-0.27 |
| (16:0) | Palmitic acid | 12.6-18.4 |
| (16:1) | Palmitoleic acid | 0.12-0.52 |
| (18:0) | Stearic acid | 5.1-8.5 |
| (18:1) | Oleic acid | 17.0-39.5 |
| (18:2) | Linoleic acid | 18.1-62.8 |
| (18:3) | Linolenic acid | 0.34-0.82 |
| (20:0) | Arachidic acid | 0.26-1.12 |
| (20:1) | Gadoleic acid | 0-0.17 |
| (22:0) | Behenic acid | 0.12-0.58 |
The study did not distinguish between positional isomers (e.g. ω-3 versus ω-6 linolenic acid). The sum of myristic and palmitic acid (cholesterogenic saturated fatty acids) content ranged from 12.8 to 18.7%. The total unsaturated acid content ranged from 73.1 to 80.5%. The very long chain fatty acid (> 18 carbon atoms) content ranged from 0.44 to 1.37%.

Famous quotes containing the words seed, types and/or oil:
“Behold I have given you every herb bearing seed which is upon the face of all the earth, and every tree, in which is the fruit of a tree yielding seed; to you it shall be for meat.”
—Bible: Hebrew Genesis 1:29.
But in a later context, God told the disgraced Adam, “and thou shalt eat the herb of the field” (Genesis 3:18)
“The rank and file have let their servants become their masters and dictators.... Provision should be made in all union constitutions for the recall of leaders. Big salaries should not be paid. Career hunters should be driven out, as well as leaders who use labor for political ends. These types are menaces to the advancement of labor.”
—Mother Jones (1830–1930)
“Courage, determination, and hard work are all very nice, but not so nice as an oil well in the back yard.”
—Mason Cooley (b. 1927)
