Abstract
Cotton seeds of genetically different varieties of Gossypium hirsutum
and Gossypium arboreum were collected and stored for two years under
ambient conditions. At the time of storage the' percentage of seed oil,
starch, nitrogen, fatty acids and amino acids (μg g-1) were determined.
At the end of the storage period nitrogen content, starch and oil percentage
decreased while the free fatty acids and amino acids increased.
The nitrogen contents and consequently the crude protein content
decreased because of its hydrolysis, and hence the amino acids showed
an increase in its contents. Free fatty acids increased due to the action
of lipases on fats and due to this oil content decreased during the study.
The decrease in starch was perhaps due to the activity of hydrolytic
enzymes of starch with increasing moisture and temperature as well as
storage period.
