Solution Overview

Problem

Current sweetening compositions using artificial sweeteners pose health risks and lack natural components, while natural high-intensity sweeteners like steviol glycosides have a bitter, metallic aftertaste that needs masking to achieve a pleasant taste with reduced calorie intake.

Innovation Solution

A sweetening composition combining steviol glycosides with a natural masking agent obtained from carob and citrus fruits through an aqueous extraction and fractionation process, which includes polysaccharides, polyols, proteins, and polyphenols, effectively masking the bitter aftertaste and improving the sweetness profile.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If steviol glycosides are used as natural high-intensity sweeteners, then calorie intake is reduced and natural sweetness is achieved, but bitter and metallic aftertaste occurs

Engineering Contradiction:
Improvebitter and metallic aftertasteVSAvoidcalorie content
Core Design Contradiction:
Object-affected harmful factorsVSQuantity of substance

Solution Approach 1:

A natural masking agent derived from carob and citrus fruits is introduced as an intermediary substance to mask the bitter and metallic aftertaste of steviol glycosides. The masking agent contains polysaccharides, polyols, proteins, and polyphenols that interact with the steviol glycosides to reduce their off-tastes while maintaining the low-calorie benefit

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention creates a composite sweetening composition by combining steviol glycosides with a natural masking agent extract. This composite material integrates the low-calorie sweetening property of steviol glycosides with the taste-mask ings ability of the carob-citrus extract, achieving both calorie reduction and pleasant taste

Inventive Principle:
Principle #40Composite materials

2Quantity of substance

If artificial sweeteners are used to reduce calories, then calorie intake is reduced, but health risks and unnatural taste profile occur

Engineering Contradiction:
Improvecalorie contentVSAvoidhealth risks and unnatural taste
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The invention extracts and utilizes only the beneficial components (polysaccharides, polyols, proteins, polyphenols) from natural carob and citrus fruits to create a masking agent. This extraction process isolates the taste-improving components while removing unwanted elements, providing a natural solution without health risks

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention changes the chemical composition parameters of the sweetening system by replacing artificial sweetener molecules with a natural extract containing multiple bioactive compounds. This parameter change transforms the system from artificial to natural while maintaining calorie reduction benefits and improving taste profile

Inventive Principle:
Principle #35Parameter changes
