Malts and Malting

Author: D.E. Briggs
Publisher: Springer Science & Business Media
ISBN: 0412298007
Release Date: 1998-09-30
Genre: Technology & Engineering

This book gives a comprehensive overview of malts and malt competitors, how they are made and evaluated. Summary-outlines of the malting process and malt-using processes are followed by consideration of the structures, germinative physiology and biochemistry of cereal grains. Particular attention is paid to barley, but the malting of other cereal is described. The successive stages of malting are then considered. Topics covered include the selection and purchase of grain, its evaluation and how it is handled and stored. The types of equipment used by maltsters are described and experimental malting techniques outlined. A section devoted to the production and characteristics of materials that compete with malts, including industrial enzymes, sugar preparations and mash-tun adjuncts. The principles of malt evaluation are explained, and the effect of altering malting conditions summarized. This book should be of direct value to maltsters, brewers, distillers, foodstuff manufacturers and other malt users as well as being of more general interest to food scientists and technologists in academic research institutions.

Genre: History

The British Malting Industry since 1830 is the first overall account of malting, dealing with the processes, products and sales, owners and employees, and with the evolution of what in 1830 were almost all small, local businesses. The industry provides a good example of the benefits and limitations, so typical of British industry, of family ownership. The modern malt industry has survived a series of crises and powerful foreign competition to become a significant exporter.

Release Date: 2012-12-06
Genre: Technology & Engineering

Brewing is designed for those involved in the malting, brewing, and allied industries who have little or no formal training in brewing science. While some elementary knowledge of chemistry and biology is necessary, the book clearly presents the essentials of brewing science and its relationship to brewing technology. Brewing focuses on the principles and practices most central to an understanding of the brewing process, including preparation of malt, hops, and yeast; the fermentation process; microbiology and contaminants; and finishing, packaging, and flavor. The second edition gives more emphasis to engineering and technological aspects, with the three new chapters on water, engineering and analysis. Brewing, Second Edition, is both a basic text for traditional college, short, and extension courses in brewing science, and a basic reference for anyone in the brewing industry.

Control of Microbial Proliferation on Sorghum During Malting

ISBN: OCLC:956381364
Release Date: 2013
Genre:

In many African countries, including South Africa, sorghum is malted for the brewing of traditional beer. In South Africa, most sorghum malting is by traditional outdoor floor malting, whereby the sorghum grain is steeped for about 8 hours, left outdoors to germinate in an uncontrolled environment. These malting conditions (wet grain and more or less ambient temperature) encourage microbial proliferation. Microorganisms may themselves negatively impact on the safety of the malts. Of more concern is the proliferation of fungi which can potentially produce highly poisonous mycotoxins in the sorghum malt. Microbial proliferation can also affect the quality of malt, and thereby resulting in undesirable malts. Therefore there is a need for efficient and safe ways to control microbial growth during sorghum malting. The aim of this research was to determine processes to produce sorghum malt that is free of unwanted yeasts, coliforms, moulds and mycotoxins. The first process investigated involved turning the grains during germination. The second process involved the addition of dilute sodium hydroxide (NaOH)/ caustic soda and calcium hydroxide [(Ca(OH)2]/lime during steeping and the third process was by the use of biological control methods which involved inoculation with microbial starter cultures. The effect of the three processes on the levels of moulds, coliforms, mycotoxins (aflatoxins, fumonisins, deoxynivalenol and zearalenone), cytotoxicity, expressed in terms of their IC50 (Inhibitory concentration resulting in 50% inhibition of the cleavage activity) and quality in terms of diastatic power (DP) of sorghum malt were investigated. Turning the sorghum grains during germination did not affect the microbial load of the malt. The total bacterial counts were at high levels of 107-109 cfu/g, fungi at 104-106 cfu/g and coliforms at 103-105 cfu/g. Turned and unturned grains produced malt which showed contamination by about 8 different mould species. Some of these moulds (Fusarium verticillioides, Phoma sorghina. Aspergillus flavus, Alternaria alternata and Penicillium spp.) are known to produce mycotoxins. Malt samples contained fumonisins, deoxynivalenol and zearalenone at levels of 0.25-2 _g/g, 15-20 and 10-15 _g/kg, respectively. However, they all had very low cytotoxicity (IC50 from 31.2 to 500 mg/kg). Turning had the negative effect of decreasing the DP of the sorghum malt. The reason that turning did not reduce the microbial load is probably due to the fact that the blending of malt as a result of turning ensured that bacteria and moulds were evenly distributed throughout the malt bed. Steeping sorghum grains in 0.2% NaOH reduced the level of microbial contamination in the malt. Coliforms and moulds were reduced from 104 and 105 cfu/g respectively, to levels of 102 cfu/g in the malt that do not pose health hazards. The high pH (10-13) that resulted from the addition of NaOH probably caused the inhibition of coliforms and moulds by distorting their cell membranes, destroying the proton gradient of the bacterium cell and thus leading to their death. Steeping in 0.2% NaOH resulted in malts with no detectable amounts of mycotoxins and no indication of cytotoxicity in the sorghum malt. A further advantage was that the DP of the 0.2% NaOH steeped malts was doubled. The addition of about 107-108 cfu/ml of Saccharomyces spp. and Pediococcus. pentosaceus cultures to steep water reduced moulds in the malt from 104 cfu/g to 102 cfu/g and coliforms from 104 cfu/g to 102 and

Genre: Juvenile Nonfiction

This book was written to provide an integrated account of barley, induding its cultivation, nature and uses. An attempt has been made to cut across the unjustified and obstructive divisions between pure science, applied science, technology, botany, biochemistry, agronomy, and so on. Limitations of space preclude the use of more illustrative material or references, or even complete accounts of various topics. However sufficient information is given to enable the reader to understand the general principles and to find his or her way readily into the literature to obtain further information. Emphasis has been placed on general principles rather than details. In becoming familiar with the literature one becomes acquainted with the effects of the cereal or religion, the English language and the development of agriculture and biochemistry. The comparison between 'parallel literatures' is often stimulating also. For example one is forced to conclude that many of the agricultural problems of poor 'seed vigour' would be overcome if seedsmen used the maltsters techniques for breaking dormancy and speeding 'post-harvest maturation'. Barley is the world's fourth most important cereal after wheat, rice, and maize. It is the most widely cultivated, being grown from the equator to 700N (Scandinavia), from the humid regions of Europe and Japan to the Saharan and Asiatic Oases, and from below sea level in Palestine to high up mountains in the Himalayas, E. Africa and S. America. Some where in the world it is being sown or harvested at every time of the year.
