Solution Overview

Problem

Conventional instant noodles struggle with reconstitution, particularly thick noodles, which remain uncooked or have poor texture when rehydrated, limiting their thickness and enjoyment.

Innovation Solution

Creating noodle strings with a multilayer structure and treating them with superheated steam, followed by controlled moisture supply and drying, to enhance reconstitution properties without affecting texture or quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of stationary object

If the thickness of noodle strings is increased, then the eating experience and smooth feeling are improved, but the reconstitution property deteriorates and cores remain uncooked

Engineering Contradiction:
Improvenoodle thicknessVSAvoidreconstitution property
Core Design Contradiction:
Length of stationary objectVSReliability

Solution Approach 1:

The noodle string is divided into a three-layer structure with distinct functional zones: outer layers for structural integrity and inner layer for enhanced water absorption and gelatinization. This segmentation allows different regions to perform different functions, enabling thick noodles to reconstitute properly without compromising overall thickness

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the noodle cross-section are given different properties: the outer layers have tighter structure for maintaining shape, while the inner layer has modified composition and structure to promote water penetration and gelatinization from the inside, ensuring complete reconstitution even in thick noodles

Inventive Principle:
Principle #3Local quality

2Reliability

If thin noodles are used, then the reconstitution property is improved, but the smooth feeling and eating experience are compromised

Engineering Contradiction:
Improvereconstitution propertyVSAvoidnoodle thickness
Core Design Contradiction:
ReliabilityVSLength of stationary object

Solution Approach 1:

By creating a three-layer structure, the invention enables thick noodles to achieve reconstitution properties previously only possible with thin noodles. The segmented design allows water to penetrate effectively through the outer layers to the inner layer, ensuring complete gelatinization while maintaining desirable thickness for smooth eating experience

Inventive Principle:
Principle #1Segmentation

3Reliability

If starch is added to the inner layer to improve reconstitution, then the reconstitution property improves, but the noodle texture is lost and making property is adversely affected

Engineering Contradiction:
Improvereconstitution propertyVSAvoidnoodle texture
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

Instead of adding starch throughout or to the inner layer (which compromises texture), the invention uses local quality modification through the three-layer structure where the inner layer has different composition and structure. This localized differentiation promotes water absorption and gelatinization without adding excess starch that would degrade noodle texture and making properties

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The three-layer noodle structure creates a composite material system where each layer has optimized composition. The outer layers maintain structural integrity and texture, while the inner layer promotes water penetration and gelatinization, achieving both good reconstitution and preserved texture through composite design

Inventive Principle:
Principle #40Composite materials

AI summary

Instant noodles are produced, which have an excellent reconstitution property, can be reconstituted by pouring of boiling water even if the noodles are thicker than before, and have excellent taste and texture. The instant noodles are produced by: making raw noodle strings each having a multilayer structure including three or more layers; spraying superheated steam to the raw noodle strings; gelatinizing the noodle strings to which the superheated steam has been sprayed; and drying the noodle strings which have been gelatinized. It is preferable to gelatinize the noodle strings by spraying the superheated steam to the noodle strings, supplying moisture in liquid form to the noodle strings, and further heating the noodle strings by using the superheated steam and/or saturated steam.
