Solution Overview

Problem

There is a need for a method to liquefy cheese without using artificial emulsifying agents, while maintaining varietal flavor and enhancing handling properties, and ensuring the product remains stable and resistant to spoilage.

Innovation Solution

The method involves heating cheese in the presence of water to a temperature greater than 82°C under controlled conditions to achieve a homogenous, low viscosity cheese mass, without additional emulsifying agents, allowing for further processing into spreadable, solid, or powdered products.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If artificial emulsifying agents are used to process cheese, then viscosity and handling properties are improved, but product quality and consumer acceptance deteriorate due to artificial additives

Engineering Contradiction:
Improvehandling propertiesVSAvoidartificial additives
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent removes artificial emulsifying agents from the cheese processing system entirely. Instead of adding external additives, the invention extracts and utilizes the natural emulsifying properties already present in cheese through controlled heating to separate and redistribute fat globules, achieving improved handling without harmful additives

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The cheese mass itself provides the emulsifying function through its inherent components. The controlled heating process enables the cheese's own fat and protein structures to self-emulsify, creating a stable dispersion without requiring external emulsifying agents. The system serves itself by utilizing its intrinsic properties

Inventive Principle:
Principle #25Self-service

2Ease of operation

If cheese is heated to high temperature to achieve liquefaction, then viscosity is reduced and handling properties are improved, but varietal flavor and product quality may be compromised

Engineering Contradiction:
Improvehandling propertiesVSAvoidloss of varietal flavor
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent employs precise parameter control, specifically heating to 82-90°C for 10-30 minutes, then cooling to 40-60°C. This controlled temperature range facilitates fat globule separation and emulsion stabilization while preserving varietal flavor compounds that would be degraded at higher temperatures. The parameter optimization balances liquefaction with flavor preservation

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The process uses periodic heating and cooling cycles rather than continuous high-temperature processing. The cheese is heated to facilitate emulsion formation, then cooled to stabilize the structure and preserve flavor, creating a periodic action that achieves both liquefaction and quality maintenance

Inventive Principle:
Principle #19Periodic action

3Ease of operation

If water is added to cheese during processing, then viscosity is reduced and pumpability is improved, but syneresis (separation of water and fat) occurs

Engineering Contradiction:
ImprovepumpabilityVSAvoidsyneresis
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent controls the temperature parameter during water addition and mixing, maintaining 82-90°C to prevent syneresis. At this temperature range, the cheese matrix remains stable and incorporates water without separating. The controlled thermal conditions ensure uniform water distribution while preserving the integrity of the fat-protein-water emulsion

Inventive Principle:
Principle #35Parameter changes
