Abstract
Due to their unique seed composition, high quality of proteins, fat and squalene and extremely small starch granules, dietary fibre and lectins, grain amaranths have become a subject of many biochemical, pharmaceutical and medical investigations. As a relatively new and alternative crop grain amaranths have been only recently included in breeding programmes, investigations of biological potential and adaptability, studies of different agrotechnical factors and their effects on growth, development yield and yield quality.
There remain some unanswered questions we would like to explain in our study, where we will continue with studying the basic questions regarding first growth stages for the purpose of better understanding of the situation in applied research and in praxis. In the second part, seed amount of crude protein, minerals, fat and fat composition of grain amaranth A. cruentus will be evaluated. The flour extraction with different mills and milling procedures, composition of obtained flour fractions, rheological characteristics (amylograph, farinograph and extensiograph) of various blends of amaranth-wheat flour will be evaluated. The baking properties of various kinds of bread made with amaranth flour supplementation will be described. Because the effects of some climatic and producing conditions on above mentioned properties have not been investigated yet, the analyses will be carried out on seed lots from experiments investigating year, sowing date, nitrogen rate and plant densities on yield of Amaranthus cruentus.
Significance for science
The research will contribute to the basic knowledge of the effects of some climatic and producing factors (temperature, day length, soil texture, soil humidity) on initial growth stages (germination and emergence), the effects of year and producing factors (time of sowing, sowing density, nitrogen rate) on the compositions of amaranth seed and rheological properties of dough with different shares of amaranth flour.
Significance for the country
Results of the project will clarify key parameters influencing germination and growth of plants and support grain amaranth production as well as applied research. Seed composition, flour extraction and rheological dough properties will also be researched which can serve as the basis for completion of nutritionally rich food.
