Estimating technological quality in wheat by Hagberg falling number and Amylograph peak viscosity

Abstract

Amylolytic activity in 15 winter wheat cultivars has been followed by a comparative analysis of the values of peak viscosity on Brabender Amylograph (BU) and the values of falling number (FN) according to Hagberg (sec). Only one cultivar, Renesansa, had the peak viscosity below 500 BU and the FN below 250 sec. Four cultivars had the peak viscosity between 500 and 800 BU, seven cultivars between 800 and 1500 BU and three cultivars above 1500 BU. Twelve cultivars had the FN between 250 and 300 sec and only two above 300sec. The obtained values were compared against the values of bread made from the flour of these varieties. Bread quality was assessed as baking score (BS) via crumb quality, the parameter that represents the numerical expression of crumb elasticity and pore structure fineness.
