Solution Overview

Problem

Existing chunks in gravy food compositions experience uneven chunk distribution due to the breakdown of guar gum, leading to a loss of viscosity and unappealing appearance, which affects digestibility and fecal quality.

Innovation Solution

The use of a novel combination of 0.1 to 0.2% guar and 0.1 to 0.2% deacetylated xanthan in the gravy, maintaining viscosity and ensuring even chunk distribution, with a chunks to gravy ratio of 25:75 to 60:40, resulting in improved digestibility and fecal consistency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If guar gum is used to maintain gravy viscosity, then the gravy can support chunks evenly, but the guar gum breaks down when hot chunks are mixed in, causing viscosity loss and uneven chunk distribution

Engineering Contradiction:
Improvegravy viscosityVSAvoidchunk distribution uniformity
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The patent changes the chemical composition parameters of the thickening system by replacing guar gum with a combination of locust bean gum and pectin. This parameter change allows the gravy to maintain stable viscosity even when hot chunks are added, as the new gum combination is more heat-stable and less prone to breakdown, thereby resolving the contradiction between initial viscosity and sustained chunk distribution.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses a composite thickening system combining locust bean gum and pectin together. This composite material approach creates synergistic effects where the two gums work together to provide both initial viscosity and heat stability. The combination compensates for the weaknesses of individual gums, maintaining reliable chunk distribution throughout the product shelf life.

Principle #40Composite materials

2Stability of the object's composition

If higher amounts of gums are used to maintain viscosity, then chunk distribution improves, but digestibility and fecal quality deteriorate

Engineering Contradiction:
Improvegravy viscosityVSAvoiddigestibility
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent optimizes the concentration parameters of the thickening agents, using locust bean gum at 0.03-0.06% and pectin at 0.03-0.06%, which are lower than traditional guar gum formulations. This parameter optimization achieves the required viscosity stability while minimizing the negative impact on digestibility, as lower total gum concentrations reduce gastrointestinal discomfort and improve fecal quality.
