Mashing process

Wort. Wort is the Hquid drained off the mash tun containing maltose, a grain sugar derived from the conversion of starch during the mashing process by the action of the organic enzyme, maltase, found in badey malt. 

Maischepumpe,/. (Brewing) mash pump. Maisch-gitter, n. (Brewing) stirrer, rake, -gnt, n. (Brewing) mash goods, mash, -kessel, m. mash copper, -pfanne, /. mash copper, -prozess, m. mashing process. 

The rheo cells can easily be replaced by various types of mixers, propellers or paddles (Figure 2.1.10). It is then possible to analyze the temporal evolution of chemical/physical reactions of mixing, demixing and sedimentation of materials in process engineering, e.g., during the mash process or fermentation [28, 29]. The stirring mechanics and speed can be optimized for various materials of different particle sizes and viscosity. 

In the case of berry fruit, the enzyme should already have been added before the mashing process, as otherwise it is difficult to achieve a uniform distribution in the mash. Mashes which are stirred for a long time at elevated temperatures become mushy and the fine suspended solids content increases markedly. This may subsequently lead to considerable difficulties during clarification. 

Mashing.—The mash is then pumped to the mash tun and water, or liquor from the spent slop tank if a sour mash is desired, is introduced in sufficient quantity to make the ratio of the total mash 40 gallons of liquid per bushel of grain and the batch is agitated while the mashing operation proceeds under temperatures and conditions approximately equivalent to those previously described under mashing processes. ... 

Lysophosphatidyl cholines (LPC), which occur in cereal as amylose inclusion compounds (starch lipids cf. 15.2.5), reduce the foam stability. The terrqterature management during the mashing process regulates the LPC concentration because it determines the activity ratio of a-amylase, which contributes to the release of LPC from amylose, to phospholipase B, which catalyzes the... 

There are several conunercial mashing processes. Independent of the mashing procedure, the raw materials used are water, usually containing controlled levels... 

Adjunct Common name of a starchy raw material mixed with diastatic malt during mashing processes for beer or alcoholic spirit production. Most adjuncts are refined fractions or starches obtained from dry- and wet-milling processes. The most widely used adjuncts are refined maize and rice grits, maize starch, ground barley, and syrups. Upon hydrolysis, adjuncts provide fermentable carbohydrates and soluble peptides, the key ingredients for the fermenting yeast.
