Enzymatic Sugar Conversion in Fruit Juice for Lowered Energy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fruit juices and purees have high energetic content due to high levels of metabolically available carbohydrates, contributing to health issues like obesity and diabetes, and existing methods for reducing caloric content often compromise on nutritional value or organoleptic properties.
Innovation Solution
A process involving enzymatic conversion of naturally occurring sugars in fruit juices and purees into non-digestible polysaccharides, such as fructans, with the help of enzymes like levansucrase, to reduce metabolically available sugars while maintaining other components at natural concentrations, thereby lowering the energetic content and enhancing nutritional value.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the content of metabolically available carbohydrates is reduced in fruit juice, then the energetic content is lowered, but the total carbohydrate content and other natural components may be compromised
Solution Approach 1:
The patent changes the molecular structure parameter of carbohydrates by converting digestible mono- and disaccharides into non-digestible polysaccharides through enzymatic action. This structural transformation reduces metabolic availability and energetic content while maintaining total carbohydrate quantity, as the polysaccharides remain present but are not broken down for energy extraction in the human digestive system.
Solution Approach 2:
The patent replaces mechanical or physical methods of sugar reduction (such as filtration or concentration) with an enzymatic biochemical process. The enzyme fructosyltransferase catalyzes the conversion of fructose into fructan polysaccharides, providing a selective chemical mechanism that reduces available energy without mechanically removing carbohydrates or compromising other fruit components.
2Loss of energy
If conventional methods are used to reduce caloric content, then energy is lowered, but nutritional value and organoleptic properties are compromised
Solution Approach 1:
The patent extracts only the metabolic availability function from the carbohydrate molecules by transforming them into polysaccharide forms that resist digestive breakdown. This selective extraction reduces caloric content while leaving the total carbohydrate mass and other nutritional components (vitamins, minerals, fiber) intact and unchanged, thereby maintaining nutritional value.
Solution Approach 2:
The enzyme fructosyltransferase acts as an intermediary catalyst that mediates the conversion of simple sugars into complex polysaccharides. This intermediary biological agent enables the reduction of available energy through controlled biochemical transformation rather than through harsh physical processes that would damage nutritional quality or organoleptic properties.
3Loss of energy
If sugars are converted into non-digestible polysaccharides, then available energy is reduced, but the formation of prebiotic components enhances nutritional value
Solution Approach 1:
The patent converts the potentially harmful excess of digestible sugars into beneficial non-digestible polysaccharides with prebiotic properties. The fructan polysaccharides formed through enzymatic conversion cannot be digested for energy but instead serve as food for beneficial gut bacteria, transforming a caloric problem into a nutritional benefit that supports digestive health while reducing available energy.
Applied Scientific Principles

Function Achieved in This Case
The process effectively reduces the available energy in fruit juices and purees by 15-40% without altering the total carbohydrate content or other natural components, producing a product with increased prebiotic value and stability, suitable for healthy diets.
