Abstract

This study examined the effects of tempe­type fermentation of spelt and green spelt grains with Rhizopus oligosporus on the content and in vitro bioavailability of B­group vitamins riboflavin and thiamine, as well as myo­inositol, a bioactive compound. The fungal fermentation resulted in approximately 2.5­fold increase in the riboflavin content in spelt. The bioavailability of B2 vitamin was high (65–86 %) and did not change in result of the treatments applied (boiling followed by fermentation). The content of thiamine was increased in tempe­type products made from spelt (by 6 %) and green spelt (by 31 %), as compared to boiled grains, which partially compensated the loss (15–36 %) of B1 vitamin after hydrothermal treatment. The fermentation was beneficial for the pool of bioavailable myo­inositol, which was higher by 37 % in the case of spelt and by 47 % in green spelt than that of the respective boiled grains. Tempe contained 100 mg (spelt) and 142 mg (green spelt) of dialysable myo­inositol per kilogram of dry product.
