Chocolate Crumb Sugar Seeding for Texture Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The chocolate crumb production process faces challenges in achieving consistent quality and texture due to the Maillard reaction, which can result in unwanted flavor profiles and equipment fouling, especially when conditions promoting this reaction are overexposed, such as prolonged heat and moisture.
Innovation Solution
A process involving mixing milk and sugar to form a sweetened condensed milk, adding cocoa mass/liquor, subjecting the mixture to conditions for sugar crystallization, drying, and seeding with sugar to promote crystallization, which reduces process time, improves texture, and enhances handling properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the mixture is subjected to prolonged heat and moisture to promote Maillard reaction, then caramel flavors are generated, but unwanted flavor profiles and equipment fouling occur
Solution Approach 1:
Sugar seed crystals are added to the mixture before the Maillard reaction occurs, initiating sugar crystallisation in advance. This preliminary action creates a controlled crystallisation environment that prevents uncontrolled Maillard reactions and subsequent equipment fouling, while still allowing desired caramel flavor development through controlled sugar crystallisation.
Solution Approach 2:
The invention changes the physical state of sugar from dissolved to crystalline form by introducing seed crystals and controlling cooling rates. This parameter change from liquid/dissolved sugar to solid crystals prevents the harmful Maillard reaction side effects while maintaining the beneficial flavor development through controlled crystallisation processes.
2Manufacturing precision
If sugar crystallisation is not properly controlled, then the crumb texture becomes powdery and equipment is fouled, but proper crystallisation requires precise temperature and time control
Solution Approach 1:
Sugar seed crystals are introduced before the crystallisation process begins, pre-establishing the crystal structure. This preliminary action simplifies the subsequent temperature and time control requirements, as the seed crystals provide a ready framework for controlled crystallisation, reducing the need for complex real-time adjustments.
Solution Approach 2:
Sugar seed crystals act as an intermediary substance that mediates between the dissolved sugar and the final crystalline structure. These seed crystals provide a controlled nucleation point that simplifies the crystallisation process, reducing the complexity of temperature and time control while ensuring consistent crumb texture.
3Productivity
If un-crystallised sugar is present in the crumb, then the crumb is easier to dry, but the crumb becomes sticky and has slower melt and flavour release
Solution Approach 1:
Sugar crystallisation is initiated in advance by adding seed crystals before the drying stage. This preliminary crystallisation action completes the sugar transformation before drying begins, ensuring the crumb has the desired non-sticky properties and fast melt characteristics, while still allowing efficient drying to proceed.
Solution Approach 2:
The invention changes the physical state of sugar from dissolved to crystalline form through controlled nucleation and crystallisation. This parameter change occurs before drying, allowing the crumb to be dried efficiently while maintaining the beneficial properties of crystallised sugar, preventing stickiness and ensuring fast melt and flavour release.
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
Seeding with sugar results in improved handling and texture profiles, reduces un-crystallized sugar, bound fat, and air in crumb particles, leading to a less sticky and faster-melting chocolate with enhanced flavor release.
Implementation Method 1
The right conditions and parameters are essential for the phase change to occur in the correct manner... whereby the mass of the material is converted from a 'doughy' paste to a powder by sucrose or sugar crystallisation
Implementation Method 2
evaporating liquid from the mixture so as to form sweetened condensed milk
Implementation Method 3
A key feature of crumb production is the Maillard reaction between proteins (present in milk and cocoa), water and reducing sugars (such as lactose, present in milk), which is responsible for the generation of caramel flavours in the crumb

AI summary
A process for the manufacture of chocolate crumb and chocolate crumb and confectionery products made using the process. The process comprises: a) providing a milk and sugar mixture or mixing together, milk and sugar so as to form a mixture; b) evaporating liquid from the mixture so as to form sweetened condensed milk; c) adding and mixing cocoa mass/liquor to the sweetened condensed; d) subjecting the sweetened condensed milk and cocoa mass/liquor mixture to conditions effective to bring about sugar crystallisation in the mixture; e) drying the mixture so as to form chocolate crumb; and f) seeding the mixture with sugar during and/or between one or more of steps (c) to (e). The mixture is seeded with sugar so as to promote crystallisation prior to and/or during and/or after sugar crystallisation.
