Table 1.
Phytate content and the proportion of the total phosphorous of selected seeds according to Eeckhout and De Paepe (1994) [42], Viveros et al. (2000) (values in ()) [43], Steiner et al. (2007) (values in []) [44] and Nagy et al. (2009) (marked with *) [14]. The main storage tissue and size of the globoids is given as discussed in Section 3.1, Section 3.2, Section 3.3, Section 3.4 and Section 3.5.
