The greatest use of barley for malting purpose mostly for brewing industry. The quality of malt depends upon various grain parameters as kernel shape, size, boldness, grain protein content etc., which affects the malt quality that is malt yield, friability, homogeneity.The availability of barley for malting is not a problem, but whatever barley is available it is very poor interims of quality and not meeting the minimum standards of malting quality. So, that identification of malt barely varieties with different grain and malt parameters, which are desired for better malt production and quality improvement, needed for various products is very essential. Potential areas that boost the production, pertinent agronomic practice studies and strengthening micro malting laboratory and expert capacity are recommended to overcome the limitations of malt barley production and malt quality improvement.

This paper aimed to investigate the influence of certain wheat and wheat malt quality indicators on limit of attenuation of wort (LAT). The experiment was conducted using wheats that have been proven to display the best malting properties with heightened total and soluble N and very good viscosity. Standard micromalting and brewing processes and analysis were applied. The obtained results showed that the quality of analyzed malts was satisfying. Statistical analysis determined no significant correlation between the limit of attenuation of wort and any of the other analyzed quality indicators. The lack of close correlations between indicators is probably due to the extremely complex intertwine of factors influencing the LAT, pointing to the fact that this particular indicator should be observed as separate and mainly variety-dependent.

Barley yellow dwarf virus (BYDV) infection occurs frequently in barley in the Upper Midwest region of the United States; however, the impact of this disease on the yield and quality of malting cultivars has not been adequately addressed. Studies were conducted at Fargo, North Dakota (from 1989 to 1990) to determine the effect of BYDV infection on yield and malt quality parameters in barley. Three malting cultivars varying in yield potential and malting characteristics were artificially inoculated at the seedling stage with a North Dakota BYDV isolate of the PAV serotype. Overall yields were reduced 32.5 to 38% in 1989 and 8.5 to 19.8% in 1990 by BYDV infection. Thousand-kernel weight (3.2 to 14.9%) and kernel plumpness (11.9 to 38.9%) also were reduced. Kernel color and three malt quality parameters (α-amylase, malt recovery, and wort viscosity) were not affected by BYDV infection. Increases in wort protein (2.5 to 14.5%) and diastatic power (3.8 to 12.6%), and decreases in malt extract (1.1 to 5.6%) were found. Most notably, total protein increased 4.6 to 17.5% with BYDV infection. Higher proportions of thin seed, as a result of BYDV infection, contributed to the effects on several quality parameters. In summary, the negative effect of BYDV infection on overall quality is significant and should be considered when assessing the impact of this disease. Although annual BYD disease-related losses are typically not extensive in the Midwestern malting barley region, the incorporation of host resistance into recommended cultivars would ameliorate the negative effects of BYD disease on crop quality as well as on yield.

Canadian malt barley in the past was downgraded on visual detection of any immature barley kernels. The quality of malt made from immature barley has been investigated in the past, but conclusions were inconsistent. The factor, though, was removed from Canadian malting barley grades in August 2008. The present study used a different approach to investigate the effects of immature kernels on malt quality. A series of commercial malt barley samples were adulterated with varying levels of immature kernels. Samples were visually graded, malted and analysed for malt quality. Immature kernels were found to affect malt quality, but only significantly when samples contained 2% or more immature kernels. Soluble protein, which increased in samples with more immature kernels, was the quality factor of greatest concern. Canadian malt is often criticized for high soluble protein, which can lead to an unacceptably high wort colour. The research supported downgrading of samples on account of immature kernels, but only when the level was 2% or higher. However, grain inspectors consistently downgraded the experimental samples with as low as 0.2% immature kernels, as per the previous grade determinants. The new grade schedule has no tolerances for immature kernels, but this study supported reinstatement of a tolerance level of 2% immature kernels. Key words: Green seed, quality, malt, soluble protein, extract, wort colour

This project was initiated with the goal of investigating the malt quality of winter rye cultivars and hybrids grown in the United States in 2014 and 2015, but high levels of deoxynivalenol (DON) were subsequently found in many of the malt samples. DON levels in 75% of the investigated rye samples (n = 117) were actually below 1.0 mg/kg, as quantified by a gas chromatography combined with electron capture detector (GC-ECD). However, 83% of the samples had DON in excess of 1.0 mg/kg following malting, and the average DON level in malted rye was 10.6 mg/kg. In addition, relatively high levels of 3-acetate DON (3-ADON), 15-acetate DON (15-ADON), nivalenol (NIV), and DON-3-glucoside (D3G) were observed in some rye malts. Our results show that rye grain DON is likely a poor predicator of type B trichothecenes in malt in practice, because high levels of malt DON, 15-ADONm and D3G were produced, even when the rye samples with DON levels below 0.50 mg/kg were processed. Fusarium Tri5 DNA content in rye was highly associated with malt DON levels (r = 0.83) in a small subset of samples (n = 55). The impact of Fusarium infection on malt quality was demonstrated by the significant correlations between malt DON levels and wort viscosity, β-glucan content, wort color, wort p-coumaric acid content, and total phenolic content. Additional correlations of rye Fusarium Tri5 DNA contents with malt diastatic power (DP), wort free amino nitrogen (FAN) content, and arabinoxylan content were observed.
