Wheat-germ oil

In a study of the effect of nutrition on reproduction in the rat in the 1920s, Herbert Evans and Katherine Bishop found that rats failed to reproduce on a diet of rancid lard, unless lettuce or whole wheat was added to the diet. The essential factor was traced to a vitamin in the wheat germ oil. Named vitamin E by Evans (using the next available letter following on the discovery of vita-...

Almost any type of flour can be made as a wholemeal in principle. Wholemeal flour is what it says it is, i.e. all of the wheat. It is illegal to bleach fortify or add flour treatments to wholemeal flour. It is the only type of flour that does not have to be fortified as the natural minerals that were present in the wheat are all present in wholemeal flour. The wheat germ oil is also present. 

Another fat-soluble vitamin, E, was found by Evans and Bishop in 1923. Pregnant rats on a defined diet (alcohol-extracted casein, cornstarch, and lard) supplemented with butter (vitamins A and D) and yeast extract (vitamin B group) produced few young because of fetal resorption. Male rats on the same diet were sterile. The disorders, which have not been identified in man, were corrected by wheat-germ oil, from which tocopherol, the active ingredient, was isolated in 1936. In spite of intensive investigations and a recognition that the vitamin is an antioxidant and destroyer of free radicals, the function of vitamin E remains obscure. 

High vitamin E content (50-300 milligrams/]00 grams). Corn (maize) oil, cottonseed oil, margarine, safflower oil, soybean oil, wheat germ oil. 

Vitamin E (a-tocopherol) is most abundantly available in wheat germ oil and in small quantities in cereals, nuts, spinach, and egg yolk. Deficiency of vitamin E normally does not occur. Large doses of vitamin E are used to reduce the toxicity of vitamin A. Prolonged use causes delay in wound healing but significant...

Influence of the Nature of the Peptldic Chain. The stability of the miniemulsions decreases when liposarcosine is replaced by lipolysine and lipoglutamic acid. This result is illustrated in Table I for two different oils (styrene and wheat germ oil) for a mass ratio 0/0+W of 0.2. Although the amounts of lipopeptide and cetyl alcohol used to obtain miniemulsions have been increased from liposarcosine to lipoglutamic acid and to lipolysine, the stability of the miniemulsions decreases from more than 60 days for liposarcosine, to 12 days for lipolysine and 10 days for lipoglutamic acid. 

Influence of the Degree of Polymerization. The amounts of lipopeptide and cetyl alcohol necessary to stabilize miniemulsions increases with the degree of polymerization p of the peptidic chains of lipopeptides. The Table II illustrates this behaviour for the systems styrene/lipolysine bromhydrate and wheat germ oil/lipogluta-mic acid sodium salt.
