Uncoated Curvilinear Chewing Gum Pellets with Low-Hygroscopic Dusting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for loose bulk packaged, uncoated chewing gum in slab or slab-like formats that provides a soft initial chew, stability against moisture, and allows for the visual aspects of the chewing gum core to be perceived by the consumer, while avoiding piece wrap and hard coatings.
Innovation Solution
The use of elongated chewing gum pellets with a curvilinear shape and a low hygroscopic dusting composition, such as mannitol, to prevent sticking and maintain product stability without coatings or piece wrap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If chewing gum is packaged in loose bulk without piece wrap, then consumer convenience and waste reduction are improved, but the pieces tend to stick to one another
Solution Approach 1:
The patent applies a dusting composition specifically to the surface of individual chewing gum pieces, creating a localized anti-sticking layer only where needed. This allows the bulk packaging to remain simple and waste-free while preventing sticking at the piece surface level through targeted application of particulate matter.
Solution Approach 2:
The dusting composition acts as an intermediary substance between chewing gum pieces, preventing direct contact and adhesion between them. This intermediary layer of particulate matter (such as sugar crystals or food-grade powders) creates a barrier that eliminates sticking while maintaining the loose bulk packaging format.
2Reliability
If a hard coating is applied to chewing gum pieces, then protection from moisture and prevention of sticking are improved, but the initial chew becomes hard rather than soft
Solution Approach 1:
Instead of applying a continuous hard coating layer, the patent uses a dusting composition that creates a discontinuous, thin particulate layer on the surface. This localized approach provides moisture protection and anti-sticking properties without forming a hard shell, preserving the soft texture of the gum core during initial chewing.
Solution Approach 2:
The dusting composition uses fine particulate matter that provides temporary protection during storage and handling. This disposable-like surface treatment is sufficient for its purpose (preventing sticking and moisture gain during bulk packaging) without creating a permanent hard coating that would affect the chewing experience.
3Reliability
If a hard coating or coating format is used, then protection from environment is improved, but the visual properties of the chewing gum core are obscured
Solution Approach 1:
The dusting composition applies a thin, discontinuous layer of particulate matter on the chewing gum surface rather than a continuous coating. This localized approach provides environmental protection while allowing light to pass through and reveal the visual properties of the gum core, including colors and designs.
Solution Approach 2:
The dusting composition uses fine particulate matter that does not significantly alter or mask the underlying colors and visual characteristics of the chewing gum. The particulates are sufficiently fine and sparse to allow the gum's inherent visual properties to remain visible while still providing protective functionality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures minimal moisture pick-up and prevents individual pieces from adhering to each other during storage and use, allowing consumers to see the gum's appearance and experience a soft initial bite.
Implementation Method 1
Certain chewing gum compositions are known to either gain moisture from the surroundings or lose moisture to the surroundings depending upon the chewing gum ingredients and the relative humidity of the surrounding environment
Implementation Method 2
The hard coating also prevents the individual pieces from sticking to one another when bulk packaged as loose units
