Lipid Metabolism in Dehydrating Peanut Kernels.

Metabolism of radioactive lipids in kernels from peanut plants subjected to ¹⁴CO₂ under field conditions was studied during dehydration (curing) of the seeds at 22°C or 50°C. Synthesis of lipid was predominant during the first 6 to 12 hours of dehydration whereas degradation dominated between 12 to 24 hours of curing. These changes were related to the moisture content of the dehydrating kernels; a moisture range of 42 to 47 % was found to be an important factor influencing the observed pattern of lipid metabolism. The results from the present study also indicate compartmentalization of lipid metabolism in dehydrating peanut kernels. [ABSTRACT FROM AUTHOR]
