The stirrers of different materials used in chocolate conches have a significant impact on the taste of chocolate. This is mainly reflected in the following aspects:
1. The influence of material on chocolate ingredients
Metal ion migration:
Certain metal stirrers, such as non-food grade alloys, may react with the chocolate raw materials during the conching process, causing metal ions to migrate into the chocolate.
These metal ions may have adverse effects on the flavor and texture of chocolate, such as producing off-flavors or making the chocolate taste rough.
Chemical stability:
Materials such as food-grade stainless steel have excellent chemical stability and are not prone to chemical reactions with chocolate raw materials.
This helps maintain the original flavor and texture of the chocolate and avoids off-flavors or texture changes caused by chemical reactions.
2. The influence of material on chocolate texture
Shear force difference:
Mixers made of different materials may produce different shear forces when rotating.
The size of the shear force directly affects the fineness and texture of the chocolate material. For example, some materials may be more likely to produce larger shear forces, making the chocolate material more delicate; while other materials may produce less shear force, resulting in larger chocolate particles and a rough texture.
Thermal conductivity:
Different materials have different thermal conductivities. Materials with good thermal conductivity can transfer heat faster, allowing the chocolate material to reach the required temperature faster during the refining process.
Temperature is one of the important factors that affects the texture of chocolate. Appropriate temperature can make the chocolate material softer, easier to mix and finer; while too high a temperature may cause the fat in the chocolate to melt excessively, affecting the taste and stability.
3. The influence of material on chocolate flavor
Flavor substance release:
The material of the stirrer may affect the release of flavor compounds in the chocolate. Some materials may more easily promote the release of flavor substances, giving chocolate a richer flavor; while other materials may inhibit the release of flavor substances, resulting in a lighter chocolate flavor.
Flavor substance adsorption:
Certain materials may adsorb flavor compounds in chocolate. This may result in the loss of flavor substances by being adsorbed by the stirrer during the conching process, thus affecting the final flavor of the chocolate.
The stirrers of different materials used in chocolate conches have a significant impact on the taste of chocolate. When selecting the mixer material, it is necessary to comprehensively consider its impact on the composition, texture and flavor of the chocolate to ensure that the final chocolate produced has excellent taste and quality. Generally speaking, materials such as food-grade stainless steel are widely used in chocolate conches due to their good chemical stability, thermal conductivity and promotion of the release of flavor substances.
