Solution Overview

Problem

Existing methods for reducing calorie content in fruit and vegetable juices often impair the flavor and juice liquid properties, as they non-selectively remove low molecular components along with saccharides, or fail to provide clear health functionality.

Innovation Solution

Treatment of fruit or vegetable juice with a crude enzyme preparation of fructosyl transferase having substantially no pectinase activity to convert sucrose into fructooligosaccharide, maintaining the flavor and juice liquid properties while reducing calorie content.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If saccharides are selectively removed from fruit juice or vegetable juice, then calorie content is reduced, but intrinsic flavor and juice liquid properties are spoiled

Engineering Contradiction:
Improvecalorie contentVSAvoidintrinsic flavor and juice liquid properties
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The patent extracts and removes only saccharides from fruit juice or vegetable juice using a specific membrane separation process, leaving other components intact. This selective extraction reduces calorie content while preserving the intrinsic flavor and juice liquid properties that would otherwise be lost with non-selective removal methods.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies local quality by targeting only the saccharide components for removal while leaving other components (flavor compounds, nutrients, etc.) unaffected. This localized action on specific molecules allows calorie reduction without compromising the overall quality and characteristics of the juice.

Inventive Principle:
Principle #3Local quality

2Loss of energy

If amount of fruit juice or vegetable juice is reduced to lower saccharides, then calorie content is reduced, but intrinsic flavor and health functionality are impaired

Engineering Contradiction:
Improvecalorie contentVSAvoidintrinsic flavor and nutrients
Core Design Contradiction:
Loss of energyVSQuantity of substance

Solution Approach 1:

Instead of removing entire juice components, the patent selectively extracts only saccharides from the juice. This allows the full amount of fruit juice or vegetable juice to be retained, preserving all intrinsic flavors, nutrients, and health functionalities while achieving calorie reduction through targeted saccharide removal.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies local quality by acting specifically on saccharide molecules within the juice matrix, leaving all other beneficial components untouched. This selective approach reduces calories without reducing the quantity or quality of flavor compounds, vitamins, minerals, and other nutrients.

Inventive Principle:
Principle #3Local quality

3Loss of energy

If non-selective filtration is used to remove saccharides, then calorie content is reduced, but other low molecular components are also removed

Engineering Contradiction:
Improvecalorie contentVSAvoidjuice composition integrity
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The patent employs a selective extraction process using a specific membrane that removes only saccharides from the juice. This targeted extraction spares other low molecular components such as flavor compounds, amino acids, and organic acids, maintaining the integrity of the juice composition while achieving calorie reduction.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies local quality through selective action on saccharide molecules only. The membrane separation process is designed to distinguish and remove only saccharides based on their specific molecular characteristics, leaving other low molecular components intact and preserving the overall compositional integrity of the juice.

Inventive Principle:
Principle #3Local quality
