Cereal Flour Composition Texture Stability Heat-Moisture Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wheat flour-containing foods often experience texture degradation over time and when reheated, failing to maintain the desired biting sensation, meltability, and light texture.
Innovation Solution
A cereal flour composition is developed by blending cereal flour with 0.2 to 10 parts by mass of an emulsifier per 100 parts by mass, followed by a heating treatment using saturated water vapor, maintaining a product temperature of 80 to 120°C for 2 seconds to 3 minutes, which includes a heat-moisture treatment rather than a dry-heat treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wheat flour is used without special treatment, then the manufacturing process is simple, but the texture degrades over time and when reheated
Solution Approach 1:
The patent applies preliminary action by performing a heat-moisture treatment on the wheat flour before it is used in food production. This pre-treatment modifies the starch structure in advance, creating a more stable texture that resists degradation during storage and reheating. The flour is treated with controlled moisture and heat to achieve partial gelatinization, which locks in the desired texture properties before the actual food manufacturing process begins.
Solution Approach 2:
The patent utilizes parameter changes by carefully controlling the moisture content and temperature during the heat-moisture treatment process. By adjusting these parameters within specific ranges (moisture content of 10-40%, temperature of 55°C or higher), the starch undergoes controlled gelatinization that improves texture stability without excessive complexity. This parameter optimization allows the flour to maintain its functional properties while gaining enhanced texture stability.
2Reliability
If the flour is subjected to extensive processing to maintain texture, then texture stability improves, but the production time and complexity increase
Solution Approach 1:
The heat-moisture treatment is performed as a preliminary step that permanently modifies the starch structure, creating texture stability that lasts through storage and reheating. This one-time pre-treatment eliminates the need for repeated complex processing steps during subsequent food manufacturing and storage, significantly reducing total production time while maintaining consistent texture quality.
Solution Approach 2:
The patent exploits phase transitions of starch during the heat-moisture treatment, where controlled gelatinization occurs at specific temperature and moisture conditions. This phase change transforms the starch from a raw state to a gelatinized state that inherently resists retrogradation and texture degradation. The process leverages the natural physical chemistry of starch to achieve texture stability efficiently without requiring prolonged or repeated processing.
3Ease of manufacture
If dry-heat treatment is used to heat the flour, then the process is simple, but the texture becomes dry and stale
Solution Approach 1:
The patent introduces moisture as an intermediary medium during the heating process. Instead of applying dry heat directly to the flour, the treatment uses controlled moisture in combination with heat to achieve the desired starch gelatinization. This moisture-mediated heating process prevents the flour from becoming dry and stale, as the moisture acts as a buffer that maintains humidity during the thermal treatment, eliminating the harmful drying effect while keeping the process relatively simple.
4Duration of action of stationary object
If the flour is stored for extended periods, then distribution and storage flexibility improves, but texture degradation occurs
Solution Approach 1:
The heat-moisture treatment is applied in advance to the flour before storage, creating a stable starch structure that resists degradation during extended storage periods. This preliminary modification of the starch through controlled gelatinization ensures that the flour maintains its texture quality even after long-term storage and subsequent reheating, effectively decoupling storage duration from texture degradation.
Solution Approach 2:
By changing the physical-chemical parameters of the starch through heat-moisture treatment (temperature, moisture content, treatment time), the patent creates a starch structure that is inherently more stable during storage. The controlled gelatinization process alters the starch crystallinity and molecular arrangement, resulting in a product that maintains its functional properties and texture quality over extended storage periods without requiring special storage conditions.

AI summary
A cereal flour composition is made by subjecting a mixture to a heating treatment, the mixture including: a cereal flour; and 0.2-10 parts by mass of an emulsifier with respect to 100 parts by mass of the cereal flour.

Preferably, the heating treatment is a heat-moisture treatment using saturated water vapor. A process for producing the cereal flour composition involves a heating step of directly applying saturated water vapor to the mixture including a cereal flour and an emulsifier, and heating the mixture, wherein the heating step is performed by using a production device including: a transporting path that transports an introduced raw material to an outlet; and a mechanism that introduces saturated water vapor into the transporting path.
