Triticale grains and brewers’ spent grain (BSG) can be new sources to develop food products. From a socio-economical point of view, this fact is important since triticale easily adapted the climatic changes BSG low-cost material which may lead “zero-waste” desiderate. In study, dough rheological properties obtained from different cultivars (Ingen 33, Ingen 35, 54, 93) cultivated in Republic Moldova fermented form (BSF) an addition level 10% 17.5% were analyzed. For purpose, devices, such as...
