Instant Coffee Foam Formation via Time-Staggered Solubility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional instant cappuccino compositions result in a brownish, unsightly milk froth due to the simultaneous dissolution of instant coffee and foam-forming coffee creamer components, which affects the aesthetic appearance of the beverage.
Innovation Solution
A composition with a coffee component and a foam-forming coffee creamer component having different time-delayed solubilities, where the coffee component is compacted to a higher bulk density and optionally coated to reduce water solubility, ensuring the coffee component settles and dissolves last, maintaining a white milk foam.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If instant coffee and foam-forming coffee creamer components are dissolved simultaneously in water, then the preparation process is simple and fast, but the milk froth becomes brownish and unsightly, impairing the aesthetic appearance
Solution Approach 1:
The patent divides the dissolution process into two distinct stages: first the foam-forming coffee creamer component dissolves to create white milk froth, then the instant coffee component dissolves separately. This segmentation prevents simultaneous dissolution, allowing the milk froth to maintain its white color while still achieving complete dissolution of both components.
Solution Approach 2:
The foam-forming coffee creamer component is designed to dissolve first in preliminary action, creating the white milk froth before the instant coffee component begins to dissolve. This timing sequence ensures that the coffee particles do not contaminate the milk froth during its formation, preserving the aesthetic appearance.
2Illumination intensity
If the coffee component is made less soluble to delay dissolution, then the milk froth remains white, but the coffee component may not dissolve completely or may require additional stirring time
Solution Approach 1:
The patent creates a dynamic dissolution system where the two components have different dissolution rates that change over time. The foam-forming coffee creamer component dissolves rapidly at first, then the instant coffee component gradually dissolves as stirring continues. This dynamic approach ensures complete dissolution of both components while maintaining the white appearance during the critical foam formation phase.
3Ease of manufacture
If both components have the same water solubility, then the composition is simple to manufacture, but the coffee and creamer mix uniformly during dissolution, causing brownish discoloration of the milk froth
Solution Approach 1:
The patent applies local quality by giving each component distinct dissolution characteristics tailored to its specific function. The foam-forming coffee creamer component has high water solubility for rapid foam formation, while the instant coffee component has controlled solubility for delayed dissolution. This localized optimization of dissolution properties for each component achieves both manufacturing feasibility and aesthetic quality.
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 effectively prevents the instant coffee from mixing with the milk froth, maintaining its white color and enhancing the visual appeal of the cappuccino beverage.
Implementation Method 1
the coffee component (A) is present in compacted form, the ratio of the bulk density of the coffee component (A) to the bulk density of the coffee creamer component (B) being at least 1.5
Implementation Method 2
at least one preferably particulate coffee whitener component (B), which contains a coffee whitener (= creamer) that forms foam under treatment with preferably hot water
Implementation Method 3
the coffee component (A) is equipped with a lower water solubility than the coffee whitener component (B)

AI summary
The invention relates to a composition, in particular for preparing a coffee-containing instant hot drink, preferably in the manner of a cappuccino drink, wherein the composition comprises a dry mixture which comprises (A) at least one preferably particulate instant-coffee-containing coffee component and (B) at least one preferably uniformly particulate coffee-whitener-containing coffee whitener component which forms foam when prepared with preferably hot water, wherein the coffee component (A) and the coffee whitener component (B) are furnished with different, in particular time-staggered water solubilities, in particular the coffee component (A) is furnished with a lower water solubility than the coffee whitener component (B), and/or the coffee component (A) and the coffee whitener component (B) dissolve staggered in time when prepared with preferably hot water, in particular the coffee component (A) dissolves delayed in time relative to the coffee whitener component (B). In this manner cappuccino drinks may be generated having a purely white cappuccino milk foam, the optical appearance of which is not impaired by brown colouration as a consequence of dissolved instant coffee.
