Abstract:

The aim of this research work was to study and compare the main parameters of the rheological state of the dough made from triticale flour (a variety of George selection by the FSBIS Agricultural Research Institute of the South-East), dough made from flour of white and red bean seeds, as well as parameters of dough from flour of composite mixtures based on them. The rheological properties of the dough were determined using a Mixolab device according to the GOST ISO 17718-2015 method. The mixing ability of the blends was additionally tested by the SDS sedimentation method. It was found that the moment of force, which characterizes the gelatinization process, correlates well with the SDS sedimentation index. To a lesser extent, this indicator correlates with the values of the moments of force characterizing the process of ‘starch retrogradation’ and the energy intensity of the dough formation process. The water absorption capacity of flour highly correlates with the moment of force during the liquefaction phase and with the moments of force characterizing the minimum and maximum consistency of the dough during the ‘starch retrogradation’ phase. The correlation between the SDS sedimentation rate and water absorption capacity was found to be rather low. The rheological parameters were also significantly influenced by the type of beans. Taking into account the results of studies of the rheological state of the dough, test baking of bread with various mass fractions of components was carried out. The results obtained confirmed the improving effect of bean flour.

Abstract:

The need for alternative protein sources to soybean meal, partially or fully substituted in the diets of dairy cows, is an urgent problem in farming nowadays. Soybean meal is the most common protein source included in feed concentrate for dairy cows in Latvia and in other European countries as well. Among possible alternatives, grain legumes seem interesting for dairy cow diets because of their rapid degradation in the rumen and readily available energy. Peas and beans will be an important source of proteins in feed. Biochemical tests were done on eight samples of domestically grown dried peas of average size, 11 samples of dried beans of average size and some samples of soybean meal to examine the chemical composition of the peas and beans. Peas and beans were included in the feed ration during a feeding trial on dairy cows. Milk yields and milk quality parameters were examined in the trial. The digestibility of peas of most varieties and breeding lines examined was considerably higher than that of soybean meal, while the digestibility of beans of all the varieties and breeding lines examined and of soybean meal was the same. The peas contained more reducing sugars, starches and had a higher value of NEL than the tested beans, which meant the peas had a higher nutritional value. The diets comprising beans and peas fed to the dairy cows increased the fat and protein contents of milk, compared with the control group and the beginning of the trial. The total amount of amino acids increased in the bulk milk samples of all the trial groups during the feeding trial.
