Seed oils sunflower

Although soybeans contribute about one-half of the world production of oilseeds, they supply less than one-third of the total edible vegetable fats and oils (Table 11) because of their relatively low oil content. Nonetheless, production of soybean oil exceeds the combined production of cottonseed, peanut, and sunflower seed oils.

Figure 29 shows the separation of triacylglycerols from sunflower seed oil. In the analysis of linoleic acid-rich seed oils, well-shaped peaks are obtained, and excellent resolution of all the main fractions is achieved, with species containing linoleic acid being predominant.

The following oils are recommended in decreasing order of preference, the bracketed numbers indicating the approximate linoleic acid content sunflower-seed oil (60), poppy-seed oil (60), cotton-seed oil (45). 

These figures are based on the use of sunflower-seed oil containing 5 7 per cent linoleic acid. With other oils, the yield will be proportionally larger or smaller, depending on the analysis of the oil. Approximate values for three oils may be calculated from the values given in Note 3 above. The yield from cotton-seed oil is 26-30 g. The checkers have brominated about nine times the amounts stated in these directions and have obtained proportionate yields. 

A) Fatty Acids.—In a 1-1. Erlenmeyer flask are placed 250 cc. of dynamite-grade glycerin (Note 1) and 40 g. (0.71 mole) of potassium hydroxide. The mixture is heated to 120-140° and is shaken by hand until the alkali is dissolved. To the hot solution there is added, in one portion (Note 2), 110 cc. (100 g., 0.11 mole) of sunflower-seed oil (Notes 3 and 4) which has been preheated to 110-115°. The hot solution is swirled vigorously until saponification is complete (Note 5). This is indicated by the formation of a...

Cmde oils generally contain phospholipids that are removed during the degum-ming stage of refining as a crude mixture (lecithin). This valuable product is the basis of the phospholipid industry, and phospholipids are used extensively in food products, in animal feeds, and in industrial processes. The major members are phosphatidylcholines, phosphatidylethanolamines, and phosphatidylinositols and are accompanied by smaller proportions of other phospholipids. Soybean oil (3.2%), rapeseed oil (2.5%), and sunflower seed oil (1.5%) contain the proportions of total phospholipids indicated in parentheses and are the main sources of commercial lecithins, especially soya lecithin. Palm oil contains little or no phospholipids (7-9). 

Sunflower seed oil is obtained from Helianthus annus grown mainly in the USSR, Argentina, Western and Eastern Europe, China, and the United States. The oil normally contains 60-75% of linoleic acid, >90% of oleic and linoleic acids combined, and virtually no linolenic acid. Its major triacylglycerols are typically LLL (14%), LLO (39%), LLS (14%), LOO (19%), LOS (11%), and other (3%).
