Ion exchangers and their use from a qualitative, commercial and ecological point of view

Ion exchange plants remain state-of-the-art in breweries and soft drinks plants, despite increasing competition from membrane technology. They have the advantage of fast response times and can be easily automated. The following paper describes the most appropriate functional principle for each operation so as to arrive at a customised solution.

Halewood: Perfect CO2 measurement without moving parts and service down time

Lambrini and Red Square are typical representatives of so-called ready to drink beverages. In Germany however, these beverage types had a clear drop in sales due to a compulsory tax, but in the rest of Europe, the fruity sweet, alcoholic mixtures (on average approximately 5% vol. alcohol, thus as much as beer) made of lemonade, spirits and several ingredients, are very popular.

The forerunner and trigger for this wave of "premixes", "PPS" (pre-packed spirits) or "RTD" (ready to drink) was England exactly ten years ago - and more specifically: Halewood Ltd. from Liverpool. The two most important brands are "Lambrini" and "Red Square" which are being sold worldwide in 31 countries.Thiedig + Co., Berlin. with an assured measuring quality, robustness and simplicity of use. ...

Is water quality adequate for beverage industry?

This article points out the new Drinking water ordinance (TrinkW 2001) to the beverage industry operations and substantiates checking their own water utilisation sites. The procedures in terms of cleaning, disinfecting and purification of the systems comply with different requirements. Horst Grund sums up both benefits and suitability and presents the new IMECA®-system.

Quality always stands in the foreground.
The media daily suggest products with convenience and quality to the consumer using advertising slogans like "from deep wells" or "highest purity". Quality is a cachet and status symbol with which good money can be earned. Each product is subject to a control and fall-back system. bear a certain risk to the biological status. ...

30 Years of Weissheimer Malz Large Scale Field Trials

2004 marked the 30th anniversary of the Weissheimer Malz Large Scale Field Trials (LSFT). These, to the best of our knowledge, largest systematic barley field trials carried out in Europe by a private company allow a scientific evaluation of new malting barley varieties. The scale of one hectare per variety and site enables the production of new malting barley varieties based on practical agricultural techniques and offers the possibility of region specific malt production on a 25 - 30 to scale. Subsequent brewing trials are carried out in cooperation with European brewers. In this article, the history of the Large Scale Field Trials is presented, results from the last 30 years discussed and future objectives in barley breeding outlined from a maltsters point of view. ...

Off-flavour training

Possible off-flavours in brewing should be recognisable and assignable based on a uniform terminology. The current status of in-house sensory theoretical and practical training makes ring analysis evaluations possible.

Consumers expect that beer, like other food, has certain odour and flavour impressions. Should beer deviate in terms of its sensory characteristics and their associated enjoyment value from this general concept, this represents a considerable deficit in terms of German food law i.e. § 17 Paragraph 1 No. 2 Letter b of the LMBG (Lebensmittel- und Bedarfsgegenstände-gesetz/German Food Law). Apart altogether from this legal technicality, the brewer might lose a loyal customer in the long term. ...

Measuring dissolved gases in packaged beverages

When measuring dissolved gases in packaged beverages, the type of package has a considerable ­influence on the result. If several gases are present, selective analysis methods are required. This article describes which package properties influence the results and which analysis methods are sufficiently selective and accurate.

Carbon dioxide and oxygen are the most important gases dissolved in beverages, nitrogen is becoming increasingly important. If several gases are present, selective analysis methods are required. It is therefore often not possible to determine the carbon dioxide content of beverages with sufficient accuracy using traditional pressure/temperature methods. It is characterized by its good solubility in beverages. ...

Next round

Foster’s has extended its offer for Southcorp until 14 April this year, thus gearing up for the next round of this protracted and hostile USD 2.5 billion takeover battle for Australia’s major wine company. In a letter to Southcorp’s shareholders Foster’s has repeated its initial offer of AUD 4.14 per share - a price which Southcorp’s board deems too low. However, Southcorp’s dithering is only part of the game to extract a better price from Foster’s, which may prove a tad bit difficult to achieve as in Southcorp’s case there is no rival bidder and Foster’s already has its foot on 18 percent of the company.
That’s why the two parties have to reach an agreement eventually, or there will be some very disgruntled Southcorp shareholders. Southcorp is a once-in-a-career opportunity.

Quality management from malt intake to grist case

Quality management - As in practically all sections of a plant, it is all about quality, costs including productivity, work safety (explosion protection), the environment (noise, dust emissions) and hygiene.

The operations covered here go from arrival of the malt truck, hopefully with a quality identical to what one has contracted for, to the grist case. Increasingly a neglected part with sometimes nasty consequences which we will address here. Beer types produced requiring small quantities of special malts, possible blending capabilities and safety considerations play a large role. On the other hand, there are malt storage costs which relate mainly to investment and interest payments for goods in stock. Expensive investment and double testing can be avoi-

Absorption integral and aniline index - optimization of quick detection of flavour stability on a routinely basis

Flavour Stability - In order to impartially analyse the flavour stability of beer and the verification of technological improvement measurements cost efficient quick detection methods like the absorption integral and the aniline index have been developed. The intention of this work was to further simplify these quick detection methods, so that they become applicable in laboratory routine.

The flavour stability of beer is an essential quality characteristic. For prognosis and analytical evaluation of flavour stability already various analysis methods are established. However, they involve quite a high instrumental effort in the laboratory to conduct this special analysis (1, 2). A rotary evaporator and a UV/VIS photometer are required.0. .. ...
