Abstract:
A process for preparing a cereal-based beverage, the method comprising: ~ providing malt or unmalted cereal grains; ~ mashing said malt or unmalted cereal grains to solubalize fermentable sugars therein the mashing comprising: - a first step wherein the malt or unmalted cereal grains are exposed to protease activity and optionally glucanase activity, the first step being carried out in a temperature interval A; - a subsequent second step wherein the malt or unmalted cereal grains are exposed to beta-amylase and alfa-amylase activity carried out in a temperature interval inhibiting the protease activity of the first step; - filtering the mashed malt or unmalted cereal grains to obtain a wort; - fermenting said wort to obtain the malt-based beverage; wherein the process comprises the addition of malt rootlets to the wort, characterised in that said malt rootlets are added to the malt or unmalted cereal grains during the second step of the mashing process at which protease activity is inhibited.
Abstract:
The present invention relates, generally, to germination and preparation of aqueous extracts of cereals (e.g. prepared through mashing), including processes used to produce beer. The invention thus provides methods for fast germination and preparation of aqueous extracts of cereals. The methods significantly speed up the process of preparing wort for production of cereal-based beverages, while maintaining the potential for preparing said wort with low levels of β-glucan. The instant invention is equally applicable to the germination and preparation of aqueous extracts of other cereal grains - including rice, sorghum, maize, millet and wheat - as well as brewing processes comprising adjuncts.
Abstract:
Method of preparing a maltbased beverage, in particular a beer, comprising the steps of: (a) In situ preparing a fermentable sugar solution; (b) Mashing malt obtaining a malt mash; (c) Filtering the malt mash obtaining a wort; (d) Boiling the wort; (e) Adding the fermentable sugar solution to the wort after filtration of the malt mash; (f) Fermenting the wort/fermentable sugar solution mixture obtaining a maltbased beverage.
Abstract:
The present invention relates to method for production of brewer's wort comprising adding to a mash, a particular glucoamylase. The glucoamylase is obtained from Penicillium oxalicum. Further, the invention relates to use of a particular glucoamylase for production of brewer's wort. Furthermore, the invention relates to use of a combination of a glucoamylase and a pullulanase for production of brewer's wort.
Abstract:
The invention relates to an improved enzyme complex having a plurality of enzyme activities of an expression product obtained by fermentation of the genus Trichoderma in combination with one or more enzymes of a different fungus strain.
Abstract:
The present invention provides a continuous method of preparing a liquid extract of cereal grain by comminuting cereal grain at a rate of at least 100 kg of dry cereal grain per hour and extracting the comminuted cereal grain with a liquid, said 5 method comprising: -continuously combining cereal grain with a liquid; -continuously disintegrating the grain particles contained within the liquid by colliding freely suspended grain particles with one or more rotating blades, thereby producing a milled suspension;10 -continuously transferring at least a part of the milled suspension, optionally after further treatment, to a separation device for separation into spent grain and liquid extract; wherein the one or more rotating blades are rotating at a tip speed of at least 10 m/s; the total mechanical energy transferred into the milled suspension by the one or more 15 rotating blades is in the range of 5-1000 k J per kg of dry cereal grain; and the distance between a tip of said one or more rotating blades and the axis of rotation is in the range of 2-25 cm. The invention also provides a system for comprising a milling apparatus and a separation device suitable for use in the aforementioned method.20 The present method and system offer several advantages, including savings on capital expenditure and maintenance, short milling times and hygienic design.
Abstract:
A process for producing a wort comprising the steps of mixing a grist with water, adding a debranching enzyme, wherein said debranching enzyme has above 60% enzyme activity, at 64°C, for a period of 10 minutes, at pH 5.0, resting said mixture at 58-68°C for a period of 10-40 minutes, resting said mixture at 72-80°C, for a period of 5-20 minutes, and separating the wort from solid components.
Abstract:
One aspect of the present invention relates to a method of producing a mash extract, said method comprising: a. mashing particulate, starch-containing and optionally malted raw materials with a recirculated aqueous stream; b. heat ing the mash and enzymatically hydrolysing the starch; c. transferring the heat-treated mash into a first separator for separation into mash extract and spent grain; d. transferring the spent grain into a first mixing vessel and mixing it with sparging water; e. transferring the mixture of spent grain and sparging water into a second separator to remove spent grain; f. recirculat ing an aqueous stream from the second separator to the mashing step, wherein the gravity of the fermentable mash extract obtained from the first separator is maintained at above 15 ºP. The present method offers the advantage that it is highly efficient in terms of energy consumption and extraction yields. Furthermore, the present method achieves extremely high productivity in the operation of the brewhouse. The invention also provides an apparatus for carrying out the aforementioned method.
