Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Acetic acid-containing foods or drinks often have unpleasant odors, including acetic acid odor and pungent odors derived from components like ethyl acetate and acetaldehyde, which deter regular consumption necessary for health benefits.

Innovation Solution

Incorporating specific concentrations of 2-butanone, 3-methylbutanal, and optionally butyl propionate and isoamyl acetate into acetic acid-containing foods or drinks to reduce odors and enhance body sensation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If acetic acid is used as a flavoring ingredient and consumed for health benefits, then the beneficial effects (improving obesity, controlling blood pressure, suppressing elevated blood glucose levels) are achieved, but unpleasant acetic acid odor and pungent odor from production/storage components (ethyl acetate, acetaldehyde) hinder intake

Engineering Contradiction:

Improvehealth benefitsVSAvoidunpleasant odor

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies this principle by using 2-butanone and 3-methylbutanal to convert the harmful pungent odor into a beneficial aromatic odor. These components specifically mask and transform the unpleasant smells of acetic acid, ethyl acetate, and acetaldehyde into pleasant fruity and floral aromas, allowing the health benefits to be achieved without the deterrent of unpleasant odors

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent applies this principle by controlling the concentration ratios of aromatic components (2-butanone and 3-methylbutanal) relative to acetic acid within specific ranges. By adjusting these parameter ratios, the odor profile is optimized to eliminate unpleasant smells while maintaining the health benefits of acetic acid consumption

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If hexanal is added to reduce acetic acid odor, then acetic acid odor is reduced, but no measures are provided for pungent odor from ethyl acetate and acetaldehyde

Engineering Contradiction:

Improveacetic acid odorVSAvoidcomprehensive odor control

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The patent applies this principle by selecting 2-butanone and 3-methylbutanal as multi-functional odor-control agents that simultaneously address multiple odor problems. These components effectively mask acetic acid odor, pungent odor from ethyl acetate, and pungent odor from acetaldehyde, providing comprehensive odor control in a single solution rather than requiring separate treatments for each odor type

Inventive Principle:

Principle #6Universality (Multi-functionality)
