Ethanol and acetic acid stoichiometry: Asahi Group HoldingsRecent Research Landscape

The technical control lever is the precise modulation of ethanol levels within the wort fermentation liquid to produce low-alcohol beverages. Engineering the balance between acetic acid formation and ethanol removal ensures flavor retention in dealcoholized products.

What technical problems is Asahi Group Holdings addressing in Ethanol and acetic acid stoichiometry?

Unpalatable low alcohol flavor profile

(11)evidences

Low-alcohol and alcohol-free beverages often suffer from a lack of body, poor mouthfeel, and an imbalance of flavor compounds compared to traditional beer. Improving the stoichiometric balance of fermentation byproducts like ethanol and organic acids restores the sensory complexity lost during alcohol reduction.

Inauthentic fermented beverage flavor

(5)evidences

The keywords indicate a focus on achieving a specific beer-like taste in malt beverages, which is often hindered by off-flavors or stoichiometric imbalances during fermentation. Controlling these flavor profiles ensures sensory consistency and consumer acceptance.

Sensory profile deficiency

(3)evidences

Non-alcoholic beverages often lack the complex sensory characteristics and mouthfeel of traditional fermented beer. Addressing this allows for a more realistic consumer experience without alcohol content.

Unbalanced fermentation flavor profile

(2)evidences

Imbalances in ethanol and acetic acid stoichiometry lead to off-flavors and inconsistent beverage quality. Precise control over these metabolic outputs ensures sensory stability and product uniformity.
