title: [Content of available lysine in gamma-irradiated soybean products].
abstract: The content in available lysine of soya protein products irradiated in a 60Co-gamma cell were investigated. The results indicate that available lysine content and crude protein content at irradiation doses of 1, 3 and 5 kGy were unaffected at the 95% significance level. During 3-month storage the irradiated samples showed no significant (p = 0,05) changes of available lysine content. In samples with high content of lecithin, which were irradiated at 1 kGy as well as non-irradiated the content of available lysine was significantly (p = 0,05) reduced after 8-month storage; the other products as well as the at 3 and 5 kGy irradiated samples showed no significant decrease. Immediately after irradiation the microflora was significantly (p = 0,05) reduced. Under the effect of radiation treatment at 3 and 5 kGy the microflora was reduced to nearly 100% after 3-month storage.
