Solution Overview

Problem

Existing methods for producing cooked and frozen pastas fail to maintain the unique chewy and resilient texture of freshly boiled pasta during long-term storage, leading to texture loss and sauce penetration issues.

Innovation Solution

Cooked pasta production involves extruding dough into noodles at high pressures (80 kgf/cm² to 200 kgf/cm²) followed by freezing, using a mixture of durum wheat flour, regular wheat flour, and starches like hydroxypropylated starch, which enhances texture retention and resistance to freezing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If fresh pasta is frozen after cooking, then storage time is extended, but the noodle surface becomes rough and texture is lost

Engineering Contradiction:
Improvestorage timeVSAvoidnoodle surface smoothness
Core Design Contradiction:
Duration of action of stationary objectVSManufacturing precision

Solution Approach 1:

The patent applies parameter changes by controlling the freezing temperature at -30°C or lower and maintaining specific water content (25-45%) in the pasta before freezing. This parameter optimization prevents ice crystal formation that would otherwise damage the noodle surface structure, thereby maintaining smooth appearance and chewy texture during long-term frozen storage.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements preliminary action by cooking the pasta to a specific degree before freezing, rather than freezing raw pasta. This pre-cooking treatment prepares the pasta structure in advance to resist freezing damage, preventing the rough surface and texture loss that occur when raw pasta is frozen.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If fresh pasta is stored in chilled state, then texture is maintained, but distribution channels are limited

Engineering Contradiction:
Improvetexture qualityVSAvoiddistribution capability
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent changes the storage parameter from chilled state to deep frozen state at -30°C or lower. This temperature parameter change enables long-term storage stability while maintaining pasta quality, thereby expanding distribution capability beyond local chilled storage limitations to wider frozen food distribution networks.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If pasta is frozen with sauce, then convenience is improved, but sauce penetrates into pasta causing deterioration

Engineering Contradiction:
ImproveconvenienceVSAvoidpasta quality
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent applies parameter changes by controlling the freezing temperature at -30°C or lower, which creates a stable frozen matrix that prevents sauce from penetrating into the pasta. This temperature parameter ensures that both pasta and sauce can be stored together frozen without quality deterioration, maintaining convenience while protecting pasta quality.

Inventive Principle:
Principle #35Parameter changes
