Solution Overview

Problem

Honey's limited shelf-life due to crystallization and high water content, which affects its texture and susceptibility to microbial growth, makes it challenging to produce a stable honey product with extended shelf-life and preserved taste and color.

Innovation Solution

A process involving heating liquid honey to 98°C under 27 inHg pressure to achieve a moisture content below 1%, followed by cooling and packaging in a water-impermeable membrane to prevent reabsorption, resulting in a solid honey product that retains the original taste and color.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If honey is submitted to vacuum drying, lyophilization, extrusion drying, thin film drying, or spray-drying to reduce moisture content, then the water content is reduced, but the resulting product still contains high moisture content due to honey's hygroscopic nature

Engineering Contradiction:
Improvemoisture contentVSAvoidshelf-life
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent applies parameter changes by subjecting honey to controlled heating at specific temperatures (98-100°C) under vacuum conditions, transforming the physical state and chemical composition to achieve permanent moisture removal. This thermal treatment parameter change enables complete dehydration while preserving honey quality, resolving the contradiction between moisture reduction and shelf-life extension.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent utilizes phase transitions by heating honey to evaporate water under vacuum conditions. The water in honey undergoes phase change from liquid to vapor, and the vacuum environment facilitates this transition by lowering the boiling point. This phase transition mechanism enables complete moisture removal without crystallization, achieving both low moisture content and extended shelf-life.

Inventive Principle:
Principle #36Phase transitions

2Quantity of substance

If honey is subjected to high temperatures for prolonged periods to remove water, then moisture content is reduced, but the chemically-physical and palatable characteristics of honey are adversely affected

Engineering Contradiction:
Improvemoisture contentVSAvoidchemical-physical characteristics
Core Design Contradiction:
Quantity of substanceVSEase of manufacture

Solution Approach 1:

The patent employs phase transitions by using vacuum conditions to lower the boiling point of water, enabling moisture removal at moderate temperatures (98-100°C) rather than high temperatures. This phase change mechanism allows efficient dehydration while preserving honey's chemical-physical characteristics and palatability, resolving the contradiction between moisture removal and quality preservation.

Inventive Principle:
Principle #36Phase transitions

Solution Approach 2:

The patent creates an inert environment by applying vacuum conditions during the dehydration process. This vacuum atmosphere prevents oxidation and other chemical reactions that would degrade honey quality at high temperatures. The inert vacuum environment enables moisture removal while maintaining honey's original chemical-physical characteristics and flavor.

Inventive Principle:
Principle #39Inert atmosphere (Inert environment)

3Ease of manufacture

If honey is packaged and stored as liquid to maintain its properties, then taste and color are preserved, but its application in the food industry is limited

Engineering Contradiction:
Improvetaste and color preservationVSAvoidapplication in food industry
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent applies parameter changes by transforming honey from liquid to solid state through controlled dehydration. This physical state change expands honey's applicability in the food industry while preserving its taste and color through gentle vacuum drying at moderate temperatures. The solid form enables new applications in confectionery, pharmaceuticals, and food processing while maintaining quality.

Inventive Principle:
Principle #35Parameter changes

4Ease of manufacture

If honey is left as liquid honey, then it maintains its original properties, but it crystallizes within days, weeks or months modifying texture

Engineering Contradiction:
Improveoriginal propertiesVSAvoidtexture stability
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The patent applies parameter changes by removing water from honey to achieve a solid state with altered physical properties. This dehydration process prevents crystallization by changing the concentration and physical state of sugars, thereby stabilizing texture while preserving original taste and color. The solid dehydrated form remains stable without crystallization.

Inventive Principle:
Principle #35Parameter changes
