 wheat germ oil

CHARACTERS

A clear,light or golden-yellow liquid,practically insoluble in water,and soluble in alcohol,miscible with light petroleum(40°C to 60°C)It has a relative density of about 0.925 and a refractive index of about 1.475.it has a thick consistency and a strong aroma, It should be kept away from high temperatures and sunshine,and kept in airproof container.BENEFITSIt is the richest source of Vitamin E than any other vegetable oil. It also has a high content of Vitamin A and Vitamin D. It is rich in protein and lecithin. It is very popular for external application due to its beneficial effects on the skin and hence is increasingly finding place in the manufacture of skin care products. Other benefits of wheat germ oil include its antioxidant properties and its effect in strengthening the immune system and restoring overall health,etc. 

IDENTIFICATION

carry out the identification of fatty oils by thin-layer chromatography(2.3.2).The chromatogram obtained is comparable with the typical chromatogram for wheat germ oil.It complies with test for composition of fatty acids(as follows)

TEST

Acid value(2.5.1) ≤20/10g

Peroxide value(2.5.5) ≤15

Unsaponifiable matter(2.5.7) ≤5%(determined on 5g)

Composition of fatty acids(2.4.22,method c)

The fatty-acid fraction of the oil has the following composition:

Palmitic acid 14~19%

Stearic acid  ≤2%

Oleic acid:12~23%

Linoleic acid 52~59%

linolenic Acid 3~10%

eicosenoic acid  ≤2%

brassicasterol(2.4.23)  ≤ 0.3%

water ≤ 0.1%(determined on 5g by the micro-determination of water.,use a mixtuer of equal volumes of methanol R and methylene chloride R as solvent.
