Isomaltulose Antioxidant for Beer Oxidation Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antioxidants for food and beverages, such as ascorbic acid, have adverse effects on taste and health, are sensitive to oxidation, and limit the shelf life of beer due to their strong reducing properties and limited flexibility in brewing processes.
Innovation Solution
The use of isomaltulose as a standalone or synergistic antioxidant in beer and beer-like drinks to reduce the formation of taste-deteriorating aging components, enhancing the endogenous antioxidant capacity without affecting the taste or introducing health risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ascorbic acid is used as an antioxidant in beer, then the antioxidant effect is improved, but the taste is deteriorated and health risks are increased
Solution Approach 1:
The patent changes the chemical identity of the antioxidant from ascorbic acid to isomaltulose, fundamentally altering the substance's properties. Isomaltulose provides antioxidant activity without the harmful taste and health effects associated with ascorbic acid, thus resolving the contradiction between antioxidant effectiveness and harmful side effects.
Solution Approach 2:
The patent employs isomaltulose, a sugar alcohol that can be metabolized and excreted without accumulating harmful effects. Unlike ascorbic acid which persists in the system and causes health issues, isomaltulose is safely metabolized, effectively replacing a potentially harmful antioxidant with a safe alternative that performs the required function temporarily and then is eliminated harmlessly.
2Reliability
If ascorbic acid is used as an antioxidant in beer, then the oxidation resistance is improved, but the sensitivity to oxidation increases
Solution Approach 1:
The patent changes the antioxidant substance from ascorbic acid to isomaltulose, which has different oxidation characteristics. Isomaltulose provides stable antioxidant protection without becoming highly sensitive to oxidation itself, thus resolving the contradiction between providing oxidation resistance and becoming vulnerable to oxidation.
3Reliability
If strong reducing agents are used as antioxidants in beer, then the antioxidant effect is improved, but undesirable reactions with food components occur
Solution Approach 1:
The patent changes the reducing strength and chemical properties of the antioxidant agent. Isomaltulose provides sufficient antioxidant activity without the excessive reducing power that causes unwanted reactions with beer components, thus resolving the contradiction between strong antioxidant effect and harmful side reactions.
