Solution Overview

Problem

Existing analog cheese products struggle to achieve high protein content without ingredient separation, particularly oil separation, and lack the firmness comparable to dairy cheese.

Innovation Solution

Incorporating native pea starch in combination with plant proteins, specifically pea and fava bean proteins, and using a specific mixing and heating process to create a high protein analog cheese with a protein content greater than 10% by weight and a firmness comparable to dairy cheese.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If plant protein content is increased in analog cheese, then protein functionality is improved, but ingredient separation occurs

Engineering Contradiction:
Improveprotein contentVSAvoidingredient separation
Core Design Contradiction:
Quantity of substanceVSStability of the object's composition

Solution Approach 1:

Pea starch acts as an intermediary substance between plant proteins and oil, preventing direct separation. The starch granules absorb excess moisture and bind to both protein and oil molecules, creating a stable emulsion structure that prevents ingredient separation even at high protein concentrations (10-15%).

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a composite material system combining plant proteins with native pea starch in specific ratios. This composite structure leverages the complementary properties of proteins (firmness, nutrition) and starch (emulsion stability, water binding) to achieve both high protein content and compositional stability without separation.

Inventive Principle:
Principle #40Composite materials

2Adaptability or versatility

If plant proteins are used to create analog cheese, then non-dairy functionality is achieved, but firmness comparable to dairy cheese is not obtained

Engineering Contradiction:
Improvenon-dairy functionalityVSAvoidfirmness
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

The patent optimizes critical parameters including pea starch content (4-15%), protein content (10-15%), and heating temperature (80-99°C) to transform the physical properties of plant proteins. Through controlled heating, the starch granules gelatinize and form a network structure that traps and supports the protein matrix, achieving firmness greater than 5000g that mimics dairy cheese while maintaining non-dairy composition.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The manufacturing process utilizes phase transition of native pea starch through controlled heating (80-99°C) to gelatinize the starch granules. This phase change transforms the starch from a crystalline to an amorphous state, creating a gel network that provides structural support and firmness to the analog cheese, enabling it to reach dairy-cheese-like consistency without using dairy ingredients.

Inventive Principle:
Principle #36Phase transitions
