alkoholdel

Alkoholdel is a term encountered in some Scandinavian and European technical literature referring to the alcohol portion of a liquid mixture. In general usage the word combines “alkohol” (alcohol) and “del” (part or portion). The concept is not a formal chemical term, but it is used to describe the fraction of a sample that is attributable to alcohols, primarily ethanol in beverages and fuel blends, as opposed to water, sugars, acids, or other components.

Definition: Alkoholdel denotes the portion of a sample that can be attributed to alcohol compounds within a mixture, and can be expressed as a concentration by weight (percent w/w) or by volume (percent v/v). It may refer to the overall alcohol content or to specific alcohol species in more complex mixtures.

Determination: Methods to estimate or measure the alkoholdel include distillation followed by volumetric or instrumental analysis, gas chromatography to quantify ethanol and other volatiles, and spectroscopic approaches such as near-infrared or refractometry in some contexts. In regulated contexts the alkoholdel aligns with standard measures of ethanol content or alcoholic strength.

Applications: It is relevant in quality control for beverages, biofuel formulations, and fermentation research, where tracking the alcohol portion helps assess fermentation efficiency, product quality, or compliance with labeling standards.

Limitations: Because the term is not a universally adopted standard, its precise meaning can vary between texts; practitioners typically use explicit measures such as ethanol concentration or alcoholic strength instead of the umbrella term alkoholdel.
