Notizen:
Bush beans, kale and soybeans were used as models for studying the effects of processing by canning and freezing upon 51Cr and 65Zn content. Plants were grown hydroponically, intrinsically labeled with 51Cr and 65Zn, and processed either by canning or freezing. Freezing resulted in 65Zn losses of 10.7% for kale, 8.6% for bush beans, and 6.7% for soybeans. A loss of 3.8% of 51Cr resulted during freezing of bush beans. Canning resulted in 65Zn losses of 23% for kale, 19.7% for bush beans, and 28.8% for soybeans. Canned bush beans and kale contained 40.7% and 62.7% respectively, less 51Cr than unprocessed samples. Freezing resulted in a greater mineral retention than canning. Less opportunity for leaching is available in freezing and reduction in radionuclide content of the vegetables by canning was accounted for by transfer to the drained liquid.
