Solution Overview

Problem

Waxy tapioca starches develop a dark, tannish or brownish color when cooked, which is undesirable for consumer preference despite not affecting textural performance.

Innovation Solution

Washing waxy tapioca starch with an aqueous alkaline or surfactant liquid to significantly reduce color formation, followed by removing the liquid, ensuring minimal modification of the starch molecules.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If waxy tapioca starch is used to provide desirable textural properties and thickness to foods, then the textural performance and viscosity stability are improved, but the starch develops a dark tannish or brownish color when cooked which is undesirable for consumer preference

Engineering Contradiction:
Improvetextural performanceVSAvoidcolor formation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The starch is treated with an aqueous decolorizing liquid (alkaline or surfactant-based) before cooking to prevent color formation during subsequent cooking processes. This preliminary treatment removes or modifies the components that would otherwise cause darkening, allowing the starch to maintain its desired textural properties while producing minimal color in the final food product.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention changes the chemical parameters of the starch by treating it with aqueous alkaline liquids or surfactant liquids, which modify the starch molecules to reduce their color-forming capability. This parameter change allows the starch to maintain its functional properties (viscosity, texture) while eliminating the harmful color development during cooking.

Inventive Principle:
Principle #35Parameter changes

2Object-affected harmful factors

If waxy tapioca starch is treated with aqueous decolorizing liquid to reduce color, then the color formation is reduced, but an additional processing step is required to remove the liquid from the starch

Engineering Contradiction:
Improvecolor formationVSAvoidprocessing steps
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

After treating the starch with aqueous decolorizing liquid, the liquid is removed through washing or centrifugation, and the starch is then ready for use. This step discards the decolorizing liquid while recovering and preserving the modified starch molecules that now have reduced color-forming capability.

Inventive Principle:
Principle #34Discarding and recovering
