Solution Overview

Problem

Existing bloom-retarding additives for chocolate and chocolate-like products affect the viscosity and handling of the chocolate during processing, necessitating modifications to composition and processing conditions.

Innovation Solution

A bloom-retarding additive composed of modified cocoa butter with specific triglyceride ratios, prepared by heating a mixture of cocoa butter and unsaturated free fatty acids to an elevated temperature for a prolonged period, maintaining a SatSatO to Sat3 ratio of ≥1.5, which enhances shelf-life without significantly impacting viscosity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If existing bloom-retarding additives are used, then shelf-life is extended, but viscosity increases and handling becomes difficult

Engineering Contradiction:
Improveshelf-lifeVSAvoidhandling
Core Design Contradiction:
Duration of action of stationary objectVSEase of operation

Solution Approach 1:

The patent modifies the triglyceride composition parameters by controlling the ratio of symmetric monounsaturated triglycerides (SatOSat) to tri-saturated triglycerides (Sat3) to be ≥1.5, and by limiting Sat3 content to ≤5% by weight. These parameter changes allow the additive to extend shelf-life while maintaining acceptable viscosity and handling properties during processing.

2Duration of action of stationary object

If bloom-retarding components are added, then visually-acceptable shelf-life is enhanced, but viscosity is impacted and processing conditions must be modified

Engineering Contradiction:
Improvevisually-acceptable shelf-lifeVSAvoidprocessing conditions
Core Design Contradiction:
Duration of action of stationary objectVSDevice complexity

Solution Approach 1:

The patent specifies precise compositional parameters for the bloom-retarding component: SatOSat/Sat3 ratio ≥1.5, Sat3 ≤5% by weight, and specific ranges for SatOSat (55-80%) and SatSatO (1.5-20%). These controlled parameters enable the additive to enhance visually-acceptable shelf-life while minimizing the need to modify processing conditions, as the composition maintains compatibility with standard chocolate processing.

3Duration of action of stationary object

If Sat3 content is increased to improve bloom-retarding effect, then shelf-life is extended, but viscosity increases significantly

Engineering Contradiction:
Improveshelf-lifeVSAvoidviscosity
Core Design Contradiction:
Duration of action of stationary objectVSForce

Solution Approach 1:

The patent limits the content of tri-saturated triglycerides (Sat3) to 5% by weight or less, while maintaining a SatOSat/Sat3 ratio of ≥1.5. This parameter control ensures that sufficient bloom-retarding effect is achieved through the controlled Sat3 content and elevated SatOSat content, while preventing excessive viscosity increase that would occur with higher Sat3 levels.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite triglyceride composition combining multiple triglyceride types (SatOSat, SatSatO, and limited Sat3) in specific ratios. This composite structure provides effective bloom-retarding properties through the synergistic combination of components, while the limited Sat3 content prevents excessive viscosity, achieving a balance between shelf-life extension and processability.
