Malting is one of the biotechnological processes that includes steeping, germination and killing of cereal in controlled environment in which hydrolytic enzymes are synthesized and cell wall, protein and starch of endosperm are largely digested. Purpose of this study was evaluation of malting quality and identification of suitable line for production of malt products. In this study, effect of malting processing on physicochemical properties including of kernel density, bulk density, thousand weight kernel, protein and cold water extract yield of EBYT and Yusuf varieties evaluated in complete randomized design plan. Experiments were made in triplicate. The results of ANOVA showed that sample type had significant effect on all physicochemical properties (p

Malting is one of the biotechnological processes that includes steeping, germination and killing of cereal. This process is performed in controlled environment in which hydrolytic enzymes are synthesized and cell wall, protein and starch of endosperm are largely digested. In this study the malting quality was evaluated in order to select the best line for malt production. The effects of malting process, on terminal velocity and physicochemical characteristics included volume, 1000 kernel weight, protein content, β-glucanase activity and cold water extract of two barely lines (EBYT-88-17 and EBYT-88-20) of Golestan Province were investigated. The experiments were done in a completely randomized design with three replications. The results of the analysis of variance showed that the type of sample (line) has a very significant impact on physicochemical and terminal velocity factors (P<0.01). Maximum and minimum volume of malt and barley corresponded to EBYT-88-20 and EBYT-88-17 respectively. The malting process reduced 1000 kernel weight, terminal velocity and increased protein amount, beta glucanase enzyme activity and cold water extraction efficiencies. The level of enzyme activity in malt resulted from EBYT-88-17 line higher than malt prepared of EBYT-88-20 line. Therefore, this line is better to use in preparation of enzyme extracts therefore in the confectionary industry, cakes and cookies.

In this project, the quantitative and qualitative characteristics of malt obtained from barley, (var. Sahra), wheat (var Tajan) and Triticale, and their admixtured malts were investigated in a completely randomized design with eight treatments to determine the optimal treatment using diastatic power, hot water extract and production of suitable raw materials for the malt beverage and bakery industries. The characteristics werehot water extract, cold water extract, diastatic power, total and soluble protein, nitrogen modification index, color and β-glucanase activity. Triticale and barley malts had the maximum and minimum Kolbach indices (p<0.05), respectively. Malt obtained from Triticale and the admixture of barley-Triticale (90:10) malts, and barley-wheat (90:10) malt had maximum and minimum (p<0.05) hot water extract, respectively. Malt obtained from an admixture of barley-wheat-Triticale (80:10:10) malt and a mix of barley-wheat (90:10) malt had the maximum and minimum (p<0.05) diastatic powers, respectively. The results showed that the addition of Triticale malt (10%) led to the production of suitable raw materials for the malts beverage industry and the addition of both Triticale and wheat (each 10%) malt for the bakery industry.
