Solution Overview

Problem

Conventional soft candy production methods result in candies that are either sticky to the teeth or lack a rich eating texture, and fail to achieve a balance between chewability and lightness.

Innovation Solution

A soft candy production method involving a candy dough with 0.2 to 5 wt% pullulan and 0.2 to 2 wt% gelatin, aerated with gas bubbles to control specific gravity not greater than 1.2, using a pulling machine with rotary arms and a roller to uniformly distribute gas bubbles, ensuring the candy is less sticky and has a rich, chewable texture.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If both pullulan and gelatin are blended in the soft candy, then the chewing texture is improved, but the candy becomes sticky to teeth

Engineering Contradiction:
Improvechewing textureVSAvoidstickiness to teeth
Core Design Contradiction:
StrengthVSObject-generated harmful factors

Solution Approach 1:

The patent optimizes the concentration parameters of pullulan (0.5-3 wt%) and gelatin (0.5-2 wt%) to achieve the right balance. By precisely controlling these parameters, the candy gains sufficient chewability while minimizing stickiness to teeth.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite material system combining pullulan, gelatin, and other ingredients (starch syrup, oil, sugar) in specific proportions. This composite approach allows the synergistic effect of multiple materials to provide both chewability and reduced stickiness simultaneously.

Inventive Principle:
Principle #40Composite materials

2Object-generated harmful factors

If only pullulan is blended in the soft candy, then the stickiness to teeth is reduced, but the eating texture becomes lacking in richness

Engineering Contradiction:
Improvestickiness to teethVSAvoideating texture
Core Design Contradiction:
Object-generated harmful factorsVSStrength

Solution Approach 1:

The patent merges pullulan and gelatin into a single candy formulation, combining the stickiness-reducing property of pullulan with the texture-enhancing property of gelatin. This merging allows both benefits to be achieved simultaneously rather than choosing one over the other.

Inventive Principle:
Principle #5Merging (Combining)

3Strength

If only gelatin is blended in the soft candy, then the eating texture becomes rich, but the candy becomes sticky to teeth

Engineering Contradiction:
Improveeating textureVSAvoidstickiness to teeth
Core Design Contradiction:
StrengthVSObject-generated harmful factors

Solution Approach 1:

The patent adjusts the concentration parameters of both pullulan (0.5-3 wt%) and gelatin (0.5-2 wt%) to optimize the balance between richness and stickiness. This parameter optimization ensures sufficient gelatin content for texture while limiting pullulan content to prevent excessive stickiness.

Inventive Principle:
Principle #35Parameter changes

4Weight of moving object

If the candy dough is aerated to reduce specific gravity, then the lightness is improved, but the eating texture becomes unsatisfactory and sticky to teeth

Engineering Contradiction:
Improvespecific gravityVSAvoideating texture
Core Design Contradiction:
Weight of moving objectVSStrength

Solution Approach 1:

The patent controls the specific gravity parameter to be within 0.6 to 1.1 by adjusting the aeration level and ingredient composition. This parameter control ensures the candy achieves lightness without sacrificing eating texture or increasing stickiness.

Inventive Principle:
Principle #35Parameter changes

AI summary

A soft candy is provided, which is less sticky to teeth, and has a light and rich eating texture and a sufficient chewability. A production method for the soft candy is also provided. The soft candy is produced by stretching a candy dough (12) containing 0.2 to 5 wt% of pullulan and 0.2 to 2 wt% of gelatin by an arm (10) of a pulling machine (3), and folding the stretched candy dough (12) by a rotary force of an arm (11) with an intermediate portion of the stretched candy dough (12) held by the arm (11). The stretching and folding step is repeatedly performed, whereby the candy dough (12) is impregnated with gas bubbles to reduce the specific gravity of the candy dough (12) to not greater than 1.2.
