Germ storage

List and Friedrich (List and Friedrich, 1989) and Rebolleda et al., (Rebolleda et al., 2012) found that SC-CO2 extracted seed oils imdergo rapid deterioration. Many factors can affect the oxidative stability of oils, including the different pre-treatments before oil extraction (com steeping, germ separation, germ storage...), fatty acid composition, concentration and stability of antioxidants and the presence of prooxidant compounds (FFA, lipid peroxides, or prooxidant metals) (List and Friedrich, 1989, Winkler-Moser and Breyer, 2011). 

Numerous studies have been conducted on SFE of com germ. Christianson et al. [99] and List et al. [100], respectively, compared the composition and stability of oils obtained by SFE, or recovered by conventional hexane extraction. The quality and storage characteristics of the defatted germ flour obtained by SFE were superior to those of germ flours obtained by hexane... 

The ovaries perform two major functions (i) the storage, maturation, and expulsion of healthy haploid germ cells (i.e., oocytes) for fertilization, and (ii) the synthesis and secretion of hormones to prepare the reproductive tissues for the establishment and maintenance of pregnancy, to properly regulate gonadotropin secretion from the hypothalamic-pituitary axis, to induce appropriate sexual behaviors, and to provide lactation. The two primary functional units in the ovaries are the maturing follicles and the corpora lutea.
