Solution Overview

Problem

Beverages containing steviol glycosides as high intensity sweeteners experience a decrease in sweetness during storage, primarily due to the conversion of RebA, a main component, which affects the overall sweetness profile.

Innovation Solution

A beverage formulation is developed with a specific mass ratio of RebM to RebA ranging from 0.52 to 1.58 and a total sweetness of 5 to 10 sucrose Brix, incorporating RebD and/or RebM to stabilize sweetness and maintain favorable flavor characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If steviol glycoside (RebA) is used as a high intensity sweetener, then sweetness is provided, but sweetness decreases during storage

Engineering Contradiction:
ImprovesweetnessVSAvoidsweetness stability
Core Design Contradiction:
Quantity of substanceVSStability of the object's composition

Solution Approach 1:

RebM is added in advance to the beverage formulation to prevent the sweetness loss that would otherwise occur during storage. The preliminary presence of RebM counteracts the conversion of RebA before storage begins, maintaining sweetness levels throughout the storage period.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention uses a composite sweetener system combining multiple steviol glycosides (RebA and RebM) in specific proportions. This composite approach leverages the complementary properties of each component: RebA provides high intensity sweetness while RebM stabilizes the overall sweetness profile during storage.

Inventive Principle:
Principle #40Composite materials

2Stability of the object's composition

If RebM is added to suppress sweetness loss, then sweetness stability is improved, but formulation complexity increases

Engineering Contradiction:
Improvesweetness stabilityVSAvoidformulation complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The invention optimizes the mass ratio parameter of RebM to RebA within the range of 0.52 to 1.58. By controlling this specific parameter range, the formulation achieves sweetness stability without requiring complex multi-component systems or precise formulation procedures.

Inventive Principle:
Principle #35Parameter changes
