Abstract
Die Erfindung betrifft ein Verfahren zur Anreicherung von Bierwuerze mit Eiweissabbauprodukten. Die Anwendung des Verfahrens ist in Brauereibetrieben moeglich. Ziel der Erfindung ist, die Bierherstellung durch Einsatz eines Nebenproduktes einer bereits technisch realisierten mikrobiellen Fermentation ohne grossen Aufwand zu erreichen, so dass zumindest die Vorteile der Anwendung von neutralen Bakterienproteasen (Verkuerzung der Gaerungs- und Reifungszeit und Verringerung des assimilierbaren Restextraktes im Bier, Verbesserung der Filtrierbarkeit und der sensorischen Eigenschaften) erreicht werden. Erfindungsgemaess wird der Maische ein proteolytischer Enzymkomplex (PEK) zugesetzt, der aus Kulturloesungen eines Mikroorganismus der Art Streptomyces griseus, bevorzugt aus Kulturloesungen von Streptomycin - bildenden Staemmen, gewonnen wird oder mit Endo-Beta-Glucanase und Alpha-Amylase gemischt und als Komplexpraeparat der Maische zugesetzt wird.The invention relates to a method for enriching Bierwuerze with protein degradation products. The application of the method is possible in breweries. The aim of the invention is to achieve beer production by using a byproduct of an already technically realized microbial fermentation without much effort, so that at least the advantages of using neutral bacterial proteases (shortening the fermentation and maturation time and reduction of assimilable residual extract in beer, improving the Filterability and sensory properties). According to the invention, the mash is admixed with a proteolytic enzyme complex (PEK) which is obtained from culture solutions of a microorganism of the species Streptomyces griseus, preferably from culture solutions of streptomycin-producing strain or mixed with endo-beta-glucanase and alpha-amylase and as a complex preparation of the mash is added.
Description
Die Eignung von PEK zur Erhöhung der Konzentration von Eiweißabbauprodukten in der Würze zeigt sich an der Erhöhung um 21% Stickstoff nach Kjeldah! und 20% Alpha-Amino-Stickstoff. Die Erhöhungen sind mit durch neutrale Bakterienprotease bewirkten Zunahmen vergleichbar.The suitability of PEK for increasing the concentration of protein degradation products in the wort is reflected in the 21% increase in nitrogen to Kjeldah! and 20% alpha-amino nitrogen. The increases are comparable to increases caused by neutral bacterial protease.
Diese Wirkung ist nicht vorhersehbar,, weil das Aktivitätsmaximum von PEK bei einem pH-Wert von 9,0 liegt, die Acidität des Maischansatzes jedoch bei pH 5,2 bis 6,1 liegt. Die überraschend hohe Aktivität von PEK ist sicherlich auf die konzertierte Wirkung der zahlreichen unterschiedlichen Proteasen von PEK gegenüber dem Komplex in Schroten gebundenen Cerealieneiweiß zurückzuführen. Diese konzertierte Wirkung wird durch die verwendete Standar.dmethode der Aktivitätsbestimmung mit gelöst vorliegenden, relativ einfach aufgebauten Casein bei pH7,0 nicht erfaßt. Vorteilhaft ist, daß die gute Wirkung von PEK unter Bedingungen erhalten wurde, die für den Eingang der neutralen Bakterienprotease als optimal gefunden worden sind. Es kann abgeleitet werden, daß bei Einstellen von PEK-spezifischen Maischbedingungen die Wirksamkeit noch verbessert werdenThis effect is unpredictable, because the activity maximum of PEK is at a pH of 9.0, but the acidity of the mash mixture is at pH 5.2 to 6.1. The surprisingly high activity of PEK is certainly due to the concerted effect of the numerous different proteases of PEK over the complex in shot-bound cereal protein. This concerted effect is not detected by the used Standar.dmethode activity determination with dissolved present, relatively simple casein at pH 7.0. It is advantageous that the good effect of PEK was obtained under conditions which were found to be optimal for the input of the neutral bacterial protease. It can be deduced that setting PEK-specific mashing conditions will further improve the effectiveness
PEK kann als Nebenprodukt der Streptomycinherstellung auf bekanntem Weg (DD-PS 248141; DD-PS 248604) in Form fester oder flüssiger Präparate hergestellt werden. Das Temperaturoptimum von PEK liegt bei pH 7,0 mit Casein als Substrat bei einer Temperatur von 45-550C und ist mit dem der neutralen Bakierienprotease vergleichbar.PEK can be prepared as a by-product of Streptomycinherstellung in a known way (DD-PS 248141; DD-PS 248604) in the form of solid or liquid preparations. The temperature optimum of PEK is at pH 7.0 with casein as substrate at a temperature of 45-55 0 C and is comparable to that of the neutral Bakierienprotease.
Im Temperaturbereich der Maltoserast (63°C) sind noch etwa 25% der Gesamtaktivität vorhanden. Bei der Abmaischtemperatur wird PEK wie auch die Bakterienprotease in wenigen. Minuten inaktiviert Bei pH 6,0 werden noch etwa 30% der am pH-Optimum von pH 9,0 gegenüber Casein als Substrat vorhandenen Aktivität bestimmt.In the temperature range of Maltoserast (63 ° C) are still about 25% of the total activity available. At the mashing temperature PEK as well as the bacterial protease in a few. Inactivated minutes At pH 6.0, about 30% of the activity present at the pH optimum of pH 9.0 compared to casein as substrate is still determined.

80kg Malzschrot und 101 kg Gerstenschrot wurden mit einem Einmaischverhäitnis von 1:3,5 nach dem Infusionsverfahren mit Rasten bei 35°C, 5O0C (60 min), 640C (60 min), 72°C und 76°Cinsgesamt 190 min gemaischt. Beim Einmaischen wurden je kg Schüttung 80TE des PEK (bestimmt als neutrale Metalloprotease) sowie 183IE Beta-Giucanase (mit nicht standardisierter Nebenaktivität Alpha-Amylase) zugesetzt. Die Acidität der Maische betrug während der 50-°C-Rast pH 6,1 und während der80kg grist and 101 kg of barley meal was mixed with a Einmaischverhäitnis of 1: 3.5 after the infusion process with detents at 35 ° C, 5O 0 C (60 min), 64 0 C (60 min), 72 ° C and 76 ° Cinsgesamt 190 min. During the maceration, 80 μg of the PEK (determined as neutral metalloprotease) and 183 IU beta-glucanase (with non-standardized secondary activity alpha-amylase) were added per kg of bedding. The acidity of the mash during the 50 ° C snap was 6.1 and during the
64-°C-Rast pH 5,8. 64 ° C-stop pH 5.8.
Vordem Kochen wurden 22 kg Zucker der Würze zugesetzt. Die Anstellwürze (Stammwürzegehalt 11,0%) enthielt 75,0 mg löslichen Stickstoff und 11,8 mg Alpha-Amino-Stickstoff je 100 ml — 20% mehr als die Vergleichssude ohne Zusatz von PEK.Before cooking, 22 kg of sugar were added to the wort. The Anstellwürze (original wort content 11.0%) contained 75.0 mg of soluble nitrogen and 11.8 mg of alpha-amino nitrogen per 100 ml - 20% more than the comparative figure without the addition of PEK.
Die-Hauptgärzeitvon7d war bei einer Temperaturführung von 6,3-8,5-6,00C um 24h kurzer als bei den Vergleichssuden. Die Differenz zwischen dem scheinbaren End-und Aussjtoßvergärungsgrad des Bieres verringert sich von 8,5 auf 4,5%.The major fermentation time of 7d was 24h shorter at a temperature run of 6.3-8.5-6.0 0 C than in the comparison wells. The difference between the apparent final and outward fermentation degree of the beer decreases from 8.5 to 4.5%.

Der Rohstoffeinsatz und die Prozeßbedingungen entsprechen denen des !.Beispieles. Die Dosierung des PEK wurde auf 315TE je kg Schüttung erhöht, wodurch ein föslicher Stickstoffgehalt von 97,5 mg und ein Aipha-Amino-Stickstoffgehalt von 15,8 mg je 100 ml Anstellwürze erreicht wurde. Als Folge davon verkürzte sich die Hauptgärzait um 36h gegenüber den Vergleichssuden.The use of raw materials and the process conditions correspond to those of the! Example. The dosage of the PEK was increased to 315 units per kg of bed, resulting in a soluble nitrogen content of 97.5 mg and an Aipha-Amino-nitrogen content of 15.8 mg per 100 ml set-up wort. As a result, the Hauptgärzait shortened at 36h compared to the comparison.
