Solution Overview

Problem

Low-alcohol beer-taste beverages lack enhanced alcoholic feeling and are marred by noticeable fermented soybeans odor due to alcohol removal and volatile aroma loss.

Innovation Solution

Incorporating specific concentrations of 2-acetyltetrahydropyridine compounds and components from an alcohol-removed wort-fermented liquid, adjusting bitterness and apparent extract concentrations, to enhance alcoholic feeling and reduce fermented soybeans odor.

VSEngineering Contradiction Analysis

1Quantity of substance

If alcohol removal treatment is applied to fermented beer to create low-alcohol beverage, then alcohol concentration is reduced, but alcoholic feeling and volatile aroma are lost

Engineering Contradiction:
Improvealcohol concentrationVSAvoidloss of alcoholic feeling and volatile aroma
Core Design Contradiction:
Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

The patent changes the chemical composition parameters of the beverage by adding specific compounds (2-acetyltetrahydropyridine at 2-10 ppb, 2-acetyl-1-pyrroline at 2-10 ppb, and 4-mercapto-4-methyl-2-pentanone at 0.5-5 ppb) to compensate for the loss of alcoholic feeling and aroma caused by alcohol removal. This maintains beer-like sensory characteristics while achieving low alcohol content.

If alcohol removal treatment is applied to fermented beer, then alcohol content is reduced, but fermented soybeans odor becomes noticeable

Engineering Contradiction:
Improvealcohol contentVSAvoidfermented soybeans odor
Core Design Contradiction:
Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

The patent adjusts the aromatic compound parameters by introducing specific sulfur-containing and nitrogen-containing compounds that mask or balance the fermented soybeans odor. The combination of 2-acetyltetrahydropyridine, 2-acetyl-1-pyrroline, and 4-mercapto-4-methyl-2-pentanone creates a flavor profile that suppresses the unwanted fermented soybeans note while preserving beer-like characteristics.
