power values followed the same trend, with values of 135, 116, and 156 [degrees]ASBC for Sublette, Harrington, and Merit, respectively.
Dark malt flours have a low diastatic
activity, due to the level of roasting required to achieve their colour, and a strong flavour profile.
Malt is used in two forms: diastatic
malted flour in a powder form or diastatic
These germplasm lines had adequate levels of wort protein, diastatic
power, and [alpha]-amylase activity
The susceptible parents both showed strong increases in their total protein, soluble protein, diastatic
power and [beta]-glucan values, while their extract and soluble/total protein values all dropped.
A strategy to breed low-protein barley with acceptable kernel color and diastatic
1995), but also limit dextrinase, and [alpha]-glucosidase is termed diastatic
power, one of the major malting quality parameters in barley (Bamforth and Barclay, 1993).
Samples were micro-malted and malt quality was assessed following the American Society of Brewing Chemists (1992) procedures for measuring malt extract, total malt protein, soluble protein, soluble:total protein ratio, extract viscosity, malt friability, diastatic
power, [alpha]-amylase activity, and extract [beta]-glucan.
power is similar to Robust, but Lacey is 18% higher in alpha-amylase and yields 0.
In contrast, other workers found no differences between the two types of barley for diastatic
activity (Day et al.
In a cross to introgress low grain protein, the donor germplasm lowered diastatic
power below the acceptable range (Goblirsch et al.
In the region on the minus arm of chromosome 7, the Harrington allele(s) had favorable effects on malt quality, conferring higher soluble protein, diastatic
power, [Alpha]-amylase activity, and fine-grind extract.
