New chocolate manufacturing technology - thoughts?
Posted in: Geek Gear - Cool Tools (Read-Only)
A professor at Temple University recently discovered a technology that helps reduce the viscosity of chocolate by applying an electric-field to the suspension. It can be thought of as running chocolate through an electric sieve. I work at a technology development and commercialization company that has full license to develop and use this device.
I was conducting some market research to see if this technology would be of interest to chocolate makers and why/why not. I would be extremely grateful if some of you could share your thoughts with me on this matter.
Thanks.
Also you can read Professor Tao's paper here:

If I understand correctly the research viscosity reduction is achieved by "aggregating" solid particles to improve "packing rate".
In chocolate manufacturing in some situations* it may be beneficial to be able to produce and use chocolate with lower fat content and suitable viscosity.
* Reducing cocoa butter content can reduce the cost of raw materials used to make chocolate. This reduction will not always reduce total cost of manufacturing and for people making fine chocolates this may be a wrong idea in general.
The main issue I see with using this technology in chocolate manufacturing is that "correct viscosity" is required at use stage where we pour tempered chocolate into moulds, use it to enrobe or coat products. At this stage chocolate contains not only cocoa, sugar and milk solids but also a certain amount of cocoa butter crystals which need to be uniformly dispersed in the mass and not "aggregated" in any way.
Unlike pumping crude oil the cost of pumping chocolate is almost negligible part of the whole manufacturing process.
I would guess that this technology may be more suitable for low cost compound manufacturing where reduction of fat content can help with cost reduction and some compounds are used without tempering.
