Study the effect of non-traditional type of flour on the quality of pasta products made of soft wheat

Pasta products are very popular among different population groups. Therefore they are promising objects for their enrichment with functional ingredients. As the enriching raw materials for the manufacture of pasta products spelt wheat flour was used. Spelt is characterized by a high content complete protein, which is composed of essential amino acids. Spelt flour exceeds the wheat one greatly in the content of unsaturated fatty acids, fiber, iron, B vitamins. The effect of different doses of spelt flour on the properties of pasta dough, semifinished and finished products was studied. Short-cut macaroni products such as vermicelli were produced on a laboratory pasta press of the type AML-2. Soft type of dough, in which the mass fraction of moisture of all samples was 32.5%, was adopted in the work due to the design of the laboratory pasta press. An increasing number of wet gluten, washed from pasta dough samples with the addition of flour from spelt due to further introduced protein was defined. The quality of all of the gluten samples was characterized as good and elastic. Increased hydration of gluten ability and reducing of the critical moisture values upon drying at introduction of 20% spelt flour was found. The low temperature mode for convective drying of pasta semi-finished products with the proposed flour additive was recommended because of its high content of active enzymes that may cause browning of products during drying. Finished products had solid flat color with a touch of milk, without dark inclusions and traces of underkneading. Boiling properties of the samples of flour from spelt were characterized as good, all the samples retained their form at 100%, the rate of dry matter loss during cooking was maintained within the regulatory documentation requirements. The studies proved the feasibility of grain spelt flour application in manufacturing of pasta products.
