Solution Overview

Problem

Existing food additives often contain harmful chemicals, and there is a need for natural, cost-effective methods and systems for producing food additives that can enhance the color, aroma, and flavor of food products.

Innovation Solution

A method involving combining tea leaves and water to form a feed slurry, processing it to remove tea essence, and adjusting the color of the resulting tea extract to create a natural coloring agent that can be added to food products.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If natural food additives are used instead of chemical additives, then safety and health benefits are improved, but production cost and complexity increase

Engineering Contradiction:
Improveharmful chemicals in food additivesVSAvoidproduction method complexity
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The patent extracts tea essence and color from tea leaves through systematic processing steps including extraction, filtration, and concentration. This isolation of the active components enables the production of natural food additives without harmful chemicals while maintaining manufacturing efficiency through focused processing of specific target compounds.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The tea extract produced serves multiple functions simultaneously: it provides natural coloring, imparting tea-like aroma and flavor, and offers health benefits associated with tea polyphenols. This multi-functionality reduces the need for separate additives and simplifies the overall manufacturing process.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Object-affected harmful factors

If tea essence is completely removed from tea extract, then natural coloring is improved, but aroma and flavor properties are lost

Engineering Contradiction:
Improvetea essence interference with coloringVSAvoidaroma and flavor compounds
Core Design Contradiction:
Object-affected harmful factorsVSQuantity of substance

Solution Approach 1:

The patent applies local quality by differentially treating different components of the tea extract. Tea essence components that interfere with coloring are removed or reduced, while aroma and flavor compounds are selectively retained. This selective processing achieves pure coloring function while preserving sensory properties through controlled extraction and separation parameters.

Inventive Principle:
Principle #3Local quality
