Beer brewing

Yeast rests in fermenting cellars in beer breweries typically have a composition of 90% beer and 10% solids, mainly yeast. The amount of this waste material is 2-3% of the annual output. It can be sold as cattle feed or discharged. In a system with 4 m 0.4 pm ceramic microfiltration membranes, beer recovery amoimts to 42-62% the concentrate contains 23% solid matter [51]. Fluxes in

The most widely available yeast biomass is a by-product of the brewing industry, where the multiplication of yeast during brewing results in a surplus of ceUs. Eor every barrel (117 L) of beer brewed, 0.2—0.3 kg of yeast soHds may be recovered. In the U.S., a substantial fraction is recovered and made available about 40 x 10 kg of brewers yeast aimually. The yeast is recovered from beer by centrifuging and dried on roUer dmms or spray dryers and sold as animal feed or a pet-food supplement. It can be debittered by alkaline extraction to remove the bitter hop residues, and is then sold mainly by the health-food industry. It is available as tablets, powder, or flakes and is often fortified with additional vitamins. Distillers yeast caimot be readily separated from the fermented mash and the mixture is sold as an animal feed supplement.

Cesium carbonate (CsfZO ) is used in the beer-brewing industry to make the head of beer foamier. It is also used in glassmaking and to enhance the taste of mineral water.

Although the latent principle of catalysis was not recognized at the time, catalysis was already used in antiquity. For example, enzymes (biocatalysts) catalyze the malting procedure in beer brewing (6000 be) or the preparation of bread and other leavened bakery products by carbon dioxide and alcohol (2000 be). However, the scientific method for catalysis development only began about 200 years ago, and its importance has continued to grow until the present day. 

Bromelain (from pineapple) has applications in milk clotting. Malt extract from barley has amylolytic enzymes used in beer brewing. 

Degradation of proteins by proteases has important implications for the quality of many foods. These include beneficial effects in the development of desirable attributes, such as texture and flavor, e.g. in cheese manufacturing, meat tenderization, beer brewing, soy and fish sauce manufacturing, and production of protein hydrolysates of various origins for different functional or nutritional purposes. The proteases involved may be endogenous to the foods or they may be added for specific pur-...

Lemonade shandy is made with shandy ale , a bitter beer brewed to 6.5% ABV to minimise transport costs. For colouring the product it is important to use an ammonia caramel as the sulphite ammonia caramels used for conventional soft drinks will react with tannins in the beer and precipitate out.

Saccharomyces are yeasts that are used for beer brewing and baking. Yeasts are unicellular fungi. They reproduce either by budding or by conjugation and are widely used as objects for the study of genetics and eukaryotic cell biology.
