Solution Overview

Problem

Existing grain-like products, such as konjac rice and rice cooked with resistant dextrin, either have an unnatural texture or limited caloric reduction when used as a replacement for regular rice, leading to an unnatural eating experience and texture differences.

Innovation Solution

A dried grain-like granular product combining resistant starch and non-resistant starch, with a preferred ratio of 20-80% resistant starch and 30-75% non-resistant starch, along with optional sugar and amino acids, to mimic the texture and caloric profile of cooked rice.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If konjac flour is used to create grain-like products, then caloric intake is suppressed, but the texture becomes soft and unnatural

Engineering Contradiction:
Improvecaloric intakeVSAvoidtexture
Core Design Contradiction:
Loss of energyVSShape

Solution Approach 1:

The patent combines konjac flour with starch and protein to create a composite material that achieves both low calorie content and natural rice-like texture. The starch and protein components compensate for the soft texture缺陷 of konjac flour alone, while maintaining the caloric suppression benefit.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent modifies the chemical composition parameters by adding specific amounts of starch (10-50 wt%) and protein (5-30 wt%) to konjac flour, transforming the texture properties from soft/unnatural to firm/natural while preserving the low-calorie characteristic.

Inventive Principle:
Principle #35Parameter changes

2Loss of energy

If resistant dextrin is added to rice, then caloric intake and blood glucose level are suppressed, but the amount is limited to 10-15% due to texture and flavor differences

Engineering Contradiction:
Improvecaloric intakeVSAvoidamount of resistant material
Core Design Contradiction:
Loss of energyVSQuantity of substance

Solution Approach 1:

The patent creates a composite formulation where konjac flour serves as the base and is combined with starch and protein, allowing resistant materials to be incorporated at higher levels (20-80 wt% konjac flour provides resistance) without the texture/flavor degradation seen when adding resistant dextrin to regular rice.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent changes the formulation parameters by using konjac flour as the primary resistant component rather than adding resistant dextrin as a supplement, enabling higher concentrations (20-80 wt%) while maintaining acceptable texture and flavor through the synergistic effect of combined ingredients.

Inventive Principle:
Principle #35Parameter changes

3Loss of energy

If resistant starch is used alone, then caloric intake is suppressed, but texture and flavor similar to ordinary rice cannot be obtained

Engineering Contradiction:
Improvecaloric intakeVSAvoidtexture
Core Design Contradiction:
Loss of energyVSShape

Solution Approach 1:

The patent formulates a composite where resistant starch (konjac flour) is combined with regular starch and protein, creating a synergistic effect where the starch and protein components restore the texture and flavor properties lost when using resistant starch alone, while maintaining caloric suppression.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent adjusts the compositional parameters by adding starch (10-50 wt%) and protein (5-30 wt%) to resistant starch, transforming the texture and flavor properties from unnatural to rice-like, while the resistant starch component (20-80 wt%) maintains the caloric suppression effect.

Inventive Principle:
Principle #35Parameter changes
