Solution Overview

Problem

Traditional processed cheeses have high sodium content, and existing methods to reduce sodium either compromise taste or require significant changes to the production process.

Innovation Solution

Replacing some natural cheese with micellar casein isolate (MCI) reduces the need for melting salts and sodium content, allowing for the production of tasty, low-sodium processed cheeses with reduced sodium levels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If traditional natural cheese is used as starting material, then desirable taste and texture are achieved, but high sodium content (1.7 g/100g or more) results

Engineering Contradiction:
Improvesodium contentVSAvoidtaste quality
Core Design Contradiction:
Quantity of substanceVSEase of manufacture

Solution Approach 1:

The patent changes the chemical composition parameters by replacing natural cheese with micellar casein isolate, which has fundamentally different sodium content characteristics. This parameter change allows achieving low sodium content (≤1.5 g/100g) while maintaining acceptable taste through controlled addition of sodium chloride and melting salts

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite material system combining micellar casein isolate with controlled amounts of sodium chloride and melting salts. This composite approach allows independent optimization of each component's contribution to taste and sodium content, resolving the contradiction between low sodium and good taste

Inventive Principle:
Principle #40Composite materials

2Quantity of substance

If potassium-based melting salts are used instead of sodium-based melting salts, then sodium content is reduced, but taste quality deteriorates

Engineering Contradiction:
Improvesodium contentVSAvoidtaste quality
Core Design Contradiction:
Quantity of substanceVSEase of manufacture

Solution Approach 1:

The patent changes the concentration parameters of sodium chloride and melting salts to optimized levels that provide sufficient taste without excessive sodium. By controlling these parameters precisely, the patent achieves taste quality comparable to traditional processed cheese while keeping sodium content low through the MCI base

Inventive Principle:
Principle #35Parameter changes

3Quantity of substance

If low sodium natural cheeses are used as starting material, then sodium content is reduced, but significant changes to production process are required

Engineering Contradiction:
Improvesodium contentVSAvoidproduction process complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent changes the fundamental material parameter from natural cheese to micellar casein isolate, which inherently requires fewer processing steps and less complex production equipment. The MCI's stable micellar structure allows direct use in processed cheese formulation without the extensive processing required for low-sodium natural cheeses

Inventive Principle:
Principle #35Parameter changes

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The method results in processed cheeses with sodium levels as low as 1.5% w/w, maintaining desirable taste and texture while reducing sodium content, and can be used to produce a variety of cheese products including slices and spreads.

Implementation Method 1

replacing at least some of the natural cheese with micellar casein isolate (MCI), and interestingly they have found that less melting salts are required for producing a MCI-containing processed cheese than for producing a traditional processed cheese

Methodology Applied
Scientific EffectMicellar casein isolate substitution:

Implementation Method 2

subjecting the dairy mixture to heat treatment at a temperature of 80-150 degrees C. for a period of 2 seconds-10 minutes

Methodology Applied
Scientific EffectHeating: Heating

Implementation Method 3

processed cheese is a special type of cheese, which is prepared by melting natural cheese in the presence of so-called melting salts (e.g. disodium-hydrogen-phosphate or tri-sodium citrate dihydrate) under moderate heating

Methodology Applied
Scientific EffectMelting: Melting
