This diploma work was assessed effects of different seed treatment (untreated flour from whole seed, flour from the uterus after soaking seeds, flour from the seeds sprouted cotyledon) by three species of legumes (Pisum sativum conv. Sativum L., Vicia faba L., Lupinus angustifolius L.) yield and composition of protein isolate obtained by isoelectric precipitation. It was found that the seeds of change most affects yield precipitated N (mg) and 45%. When determining the value of the yield of protein was affected by significant interactions (treatment and the type of legume seeds). The largest share was, however, precipitate in untreated and germinated lupine seeds, in which values are around 57%. Furthermore, the thesis was to reverse the precipitation of proteins, using which we obtained protein concentrates from different species of legumes. The yields of protein concentrates reach values in the range of 60-80%. Spectra of soluble proteins is clearly visible high concentration of isolated proteins. Variation of sprouted seeds and soaked that occurred during treatment of seeds for the collapse of proteins with higher molecular weight. Furthermore, these grafts are transferred protein extraction at pH 9.0 in the later produced protein isolates. After acid precipitation is observed on a spectrum that is re-soluble protein isolates.
