Water-Containing Foam Chocolate Texture at Freezing Temperatures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water-containing chocolates are hard in freezing temperatures and fail to adequately convey the flavor of chocolate, with some formulations using monosaccharides that result in unsatisfactory flavor profiles.
Innovation Solution
A water-containing foam-containing chocolate of the oil-in-water type is developed, with a water content between 16 wt % and 55 wt %, whipped to incorporate air bubbles, which enhances texture and flavor perception at freezing temperatures, using common chocolate dough ingredients and aqueous components like water, liquor, and meringue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If water-containing chocolate is made by kneading fresh cream or liquor into chocolate, then the texture is softened at room temperature, but the texture becomes hard again in freezing temperature range (0°C or less)
Solution Approach 1:
The patent applies parameter changes by modifying the water content to a specific range (16-55 wt%) and controlling the whipping process parameters (temperature, time, speed) to create a foam structure that maintains soft texture across temperature ranges. The whipping process transforms the physical state of the water-containing chocolate, creating air bubbles that prevent hardening at freezing temperatures while maintaining softness at room temperature.
2Ease of operation
If water-containing chocolate is made by conventional methods, then the texture is softened, but the flavor of chocolate becomes difficult to be sensed in freezing temperature range
Solution Approach 1:
The patent uses parameter changes by optimizing water content (16-55 wt%) and applying controlled whipping to create a foam structure. This foam structure maintains texture softness and enables flavor perception at freezing temperatures without requiring monosaccharides, thus preserving authentic chocolate flavor while achieving the desired textural properties.
3Ease of operation
If monosaccharide is used instead of sugar to soften chocolate, then the texture is improved, but the flavor of chocolate becomes unsatisfactory
Solution Approach 1:
The patent resolves this contradiction by changing parameters differently: instead of altering the sugar type (monosaccharide substitution), it optimizes water content (16-55 wt%) and applies whipping treatment. This approach achieves texture softness while maintaining authentic chocolate flavor, avoiding the need to compromise on sugar composition.
Solution Approach 2:
The patent applies pneumatic principles by incorporating air bubbles through whipping to create a foam structure. This introduces gas phase into the chocolate matrix, creating texture softness and improving flavor perception without requiring chemical substitutions of sugar, thus preserving authentic chocolate flavor.
4Ease of operation
If water-containing chocolate is whipped to create foam structure, then texture becomes smooth and fluffy, but processability must be controlled at room temperature and freezing temperature
Solution Approach 1:
The patent applies parameter changes by optimizing water content (16-55 wt%) and controlling whipping parameters (temperature, time, speed). These parameter optimizations ensure the foam structure achieves smooth and fluffy texture while maintaining appropriate processability at both room temperature and freezing temperatures, resolving the contradiction between texture improvement and manufacturing ease.
