Lösungen für Alkoholtests zur Messung der Proof Obscuration
There are many challenges to understanding how to test alcohol content, particularly measuring/testing alcohol proof and measuring Proof of Obscuration in flavored spirits. Alcohol producers have all the demands of manufacturing a constant product with the added burden of making a product that must comply with government measurement and labeling guidelines. In most countries, the production of alcohol is highly regulated, and tax reporting must be accurate. Government-prescribed measurement methods can be very slow, as well as require laboratory skills to produce a precise measurement. Rudolph addresses the need for alcohol producers to make fast, accurate measurements at various stages during the production process with the AlcoTest-RI®. Rudolph also addresses government requirements by providing certified instruments that will keep your production facility in full compliance.
Das Problem - Effizienz, Regulierung und Steuern
Alcohol manufacturers operate in a competitive world. They must keep costs under control and maintain efficient production to ensure profitability. However, manufacturers must report correct % ABV values and must do this to the satisfaction of the local government authority. Many governments require testing methods such as distillation for Proof Obscuration Measurements, which are very slow and can significantly disrupt production.
Für die einfache Messung der Proof-Obskuration - die Lösung für die Prüfung des Alkoholgehalts
The AlcoTest-RI® offers a certified government-compliant method and a rapid non-certified method to measure alcohol proof or % ABV. Certified results can be used for taxation purposes and will serve as the benchmark method. Using the “Production Method,” you can measure alcohol content without distillation, and also read the sugar content, which is the source of most obscuration in flavored alcoholic beverages. It just takes a few keystrokes to move between fast measurements for Proof Obscuration Measurement and the certified Government Compliant Method.
Funktionsprinzip - Messung der Beweisverfälschung
Regulatory method – Standard measuring Alcohol Proof Testing – Vodka and similar products. Vodka is a mixture of alcohol and water. The density of water and alcohol is well known, so the user simply measures a sample in the density meter, and the measurement display shows % ABV. Different countries use different scales and even different expressions of the same scale. AOAC ABV is used in the USA, OIML ABV is used in Europe, the UK uses Proof, Canada uses ABV, and the Japan Taxation Department uses AOAC Proof. These are just a few of the many scales that can be used to present % alcohol.
Regulatorische Methode
Other Products. The difficulty with many alcohol products today is that other ingredients besides alcohol and water are included in the final product. These other ingredients are important because they add unique tastes and aromas with improved “mouth feel”. The consumer likes these additional ingredients, which are generally sugar and flavorings, but they obscure the % alcohol and alter the density measurement. The USA TTB solution is for the user to distill the sample before measurement in a density meter. This distillation process is time-consuming and can take as long as 2 – 3 hours according to the US TTB. At the end of the process, the user has an alcohol-water mixture that they can measure in the density meter in the same way they would measure straight alcohol. Accuracy in regulatory mode is dependent on the model of density meter that the Alcotest-RI® is built around.
Produktionsmodus
Other Products In Production Mode, the Alcotest-RI® also measures the refractive index. Refractive Index (RI) is a proven measurement used to estimate the amount of other ingredients in the sample and correct the density meter measurement for their effect on the % alcohol value. Production Mode allows a user to obtain a result in less than 2 minutes with no sample pre-treatment. Accuracy in Production Mode is sample dependent, but is often comparable to the results obtained using a standalone density meter and distillation step. Proof Obscuration Measurement made easy.
Messung des Alkoholgehalts der Obskurität im Gleichgewicht mit der schnellen Produktion
The AlcoTest-RI® is designed to help the person in charge of an Alcohol Laboratory balance the need for both compliance and profitability. Government regulators don’t care how long it takes to make measurements; they don’t care how many resources are needed in the compliance process; they simply want accurate results done according to the approved method. The owner of the factory is interested in accurate measurements as well, but they see the laboratory as a cost center needed for compliance and meeting government regulations should be done with as few resources as possible. The AlcoTest-RI® responds to the need for fast results and the need for high-accuracy government-compliant measurements.
Messung des Nachweises der Verdunkelung in den meisten aromatisierten alkoholischen Getränken
Testing High Proof Spirits, including Bourbons, Straight Spirits, and Flavored Spirits
Hersteller von Spirituosen unterliegen im Allgemeinen den höchsten Steuersätzen und profitieren am meisten von der Verwendung des AlcoTest-RI®. Angesichts der jüngsten explosionsartigen Zunahme von aromatisierten oder verschleierten Spirituosen bedeutet die Möglichkeit, spezielle Methoden für jedes Produkt zu entwickeln, dass die Anzahl der Destillationen, die ein Labor durchführen muss, drastisch reduziert werden kann. Das AlcoTest-RI® ist die perfekte Lösung, um dies zu erreichen. Anstatt 2, 3 oder sogar 4 Destillationen für eine Charge aromatisierter Produkte durchzuführen, kann das AlcoTest-RI® diese Zahl auf eine reduzieren. Proof-Obscuration-Messung leicht gemacht!
Mit der Option AlcoCalc® kann das AlcoTest-RI® zur Berechnung von Verdünnungen von Alkohol- und Wasserlösungen verwendet werden. Die AlcoCalc® -Funktion berechnet für Sie automatisch die Wassermenge, mit der eine Lösung mit hohem %ABV auf einen gewünschten %ABV-Wert verdünnt werden kann, basierend auf bekannten Tabellen, oder wie viel Alkohol hinzugefügt werden muss, um den %ABV-Wert wiederherzustellen
Wein
There are many non-approved, quick methods for wine analysis. While wine alcohol content isn’t as critical for wine as it is for spirits, there are still regulatory requirements. 
Depending on the country, there may be a point above a certain alcohol level at which the tax rate changes (16.0 % ABV in the USA). It is critical for a winery to use an approved method when they are producing products near that point. Some of the non-approved methods are geared more toward measuring other components in wine. This may provide % ABV, but not with the accuracy available with the AlcoTest-RI®.
Alcopops / RTDs (alkoholische Dosen- und Flaschengetränke)
Many very successful soft drink manufacturers are expanding into ready-to-drink alcoholic beverages, RTDs. Beverage companies traditionally focused on monitoring Brix. Alcohol obscures this value. The correct Brix value in their soft drink manufacturing process is very important to taste. It can be maintained by correcting for the alcohol in the product obscuring the measurement. The AlcoTest-RI® solves this problem by measuring the Brix value as if no alcohol were present.
Aromen / Aromastoffe
Das Wachstum der aromatisierten Alkohole ist eine Chance für die Aromenindustrie 
manufacturers. There are relatively short production runs and high costs for these new alcoholic beverages. This means that supplying flavors to this area can be very profitable. Making test beverages can be more complicated than with non-alcoholic beverages. The AlcoTest-RI® eliminates this complexity, making alcoholic drinks as simple to measure as soft drinks. Best of all, the AlcoTest-RI® is built on top of an instrument that is already used by flavor companies for the measurement of the Specific Gravity and Refractive Index of flavors. The methods for doing these tests are included in the standard AlcoTest-RI®
Optionen für die Handhabung von Proben von alkoholischen Getränken
AlcoTest-RI® kann auch die Nachweisverfälschung mit einer Spritzenprobe messen
Loading your sample with a simple syringe is often the preferred configuration for distilleries and many flavor companies. It is the least expensive configuration and uses the lowest sample volume. It also allows the measurement of extremely viscous or rheopectic samples, which can be important in flavor companies.
AlcoTest-RI® Proof Obscuration-Messungen mit der Load Assist Option
The simplest multi-sample option, the R817, allows a user to load up to 24 samples and leave the instrument to do the rest. Like the Load Assist, the R817 displaces the previous sample with the new sample, meaning fast cycle times and no cleaning solvents.
