Diastatic Power (DP) is an important quality trait for malt used in adjunct brewing and distilling. Substantial genetic variation for DP exists within UK elite barley cultivars, but breeding progress has been slow due to the limited demand, compared to the overall barley market, and difficulties in assessing DP. Estimates of DP (taken from recommended and national list trials between 1994 and 2...

Hordeins, the natural substrates of barley (Hordeum vulgare) cysteine endoproteases (EPs), were isolated as protein bodies and degraded by purified EP-B from green barley malt. Cleavage specificity was determined by synthesizing internally quenched, fluorogenic tetrapeptide substrates of the general formula 2-aminobenzoyl-P(2)-P(1)-P(1)'-P(2)' 1-tyrosine(NO(2))-aspartate. The barley EPs preferr...

Gibberella zeae (anamorph Fusarium graminearum) causes scab (blight) in wheat and barley, and ear rot in corn. Since 1991, epidemics of Gibberella head blight have struck the Midwestern states with disastrous effects on wheat and barley growers. The fungus decreases yields and also contaminates grain with trichothecene mycotoxins that are harmful to human and animal health. To understand and co...

Abstract The basic step in beer production is mashing, during which insoluble starch chains, and to a lesser extent cell walls proteins are broken down by enzymatic hydrolysis. Since the beginning of modern brewing process there have been empirical studies into optimum effective temperatures corresponding enzymes, mashing has carried out accordingly. resulting resting proteolysis, cytolysis amy...

Beer brewing is an intricate process encompassing mixing and further elaboration of four essential raw materials, including barley malt, brewing water, hops and yeast. Particularly hops determine to a great extent typical beer qualities such as bitter taste, hoppy flavour, and foam stability. Conversely, hop-derived bitter acids account for an offending lightstruck flavour, which is formed on e...

Pre-scaling up of malt barley was conducted at Kofele District West Arsi zone Oromia regional state, to increase farmers’ capacity in production and management practices. district selected due its potential for production. One “kebele” collaboration with agricultural natural resource expert purposively based on availability land cluster farming purpose. From “Kebele” 85 farmers were as team lea...
