I can’t believe someone makes… Holographic chocolate

Holographic chocolate - Morphotinix

Holographic chocolate – Morphotinix

I’m rather partial to chocolate, and holography is a bit of a personal hobbyhorse, so you can imagine my eye was caught by news stories about holographic chocolate!

Swiss company Morphotonix are the people who make this complicated confectionery, and apparently they can add the technology without altering the taste…

Jacob Aron, of New Scientist, takes up the story:

Why settle for a bar of boring old regular chocolate when you can chow down on the holographic variety instead? Morphotonix, a company based in Lausanne, Switzerland, has developed a way to imprint holograms on to chocolate – without using additives.

Specific microstructures on the surface of the chocolate diffract light to create the holograms. It works in the same way as the security hologram on a credit card, though chocolate is trickier to work with.

Morphotonix etches the required structure into a master mould made from metal. This is then used to make plastic moulds that in turn shape the chocolate. Both dark and milk chocolate can be used, though the complex physics and chemistry of microstructures means the hologram won’t form on some varieties. “We have been testing it with many types of chocolate. Sometimes it works great and sometimes no matter how hard we try it doesn’t mould,” says Morphotonix CEO Veronica Savu.

The company started developing the technology in 2012 and is now working with a German chocolate mould manufacturer to bring it to market. The two companies are presenting the work at the Interpack packaging trade fair in Düsseldorf, Germany this week.

Savu says they are also looking at applying the same technique to moulds for other products, so that the finished items carry a mark proving their authenticity. “Instead of having a holographic sticker you can have the hologram directly embedded into any rigid plastic object,” she says. Just don’t eat them.

Diffracted light has never tasted so sweet!

    .-plagiarizing published and patented work of other researchers…

    .

    Get the story straight, Morphotonix are clearly plagiarizing published and patented work of other researchers from MIT- do a simple

    Google search for chocolate hologram for god sake – as I am sure the people at Morphotonix did… ask them if they did – and if not, why not?.

    I am surprised academic integrity appears to count for so little with the organizations involved.

    I have seen chocolate and edible holograms many times at MIT’s media lab and displayed at the MIT museum as well as for sale and in the press, ..

    This technology has been around for a while and is well documented – it was even in new scientist magazine, NY times in the 90′s!!. I was also covered in technical journals and is covered in a number of patents.

    Technology: Let them eat holograms
    13 April 1991
    Magazine issue 1764.

    An American food manufacturer has developed the next step on from the traditional seaside stick of rock: sweets with holograms printed

    on them. The three-dimensional images do not cut out any calories but they do provide decoration without any additives.

    Dimensional Foods Corporation of Massachusetts has been conducting research into which foods are capable of having holographic patterns

    stamped onto them. A hologram requires fine detail – as many as 1000 lines per millimetre. Researchers found a multitude of such

    materials, including carbohydrates, sugars, vegetable gums, starches and cellulose derivatives. The company has succeeded in moulding a

    full 3-D holographic image onto chocolate.

    First on the market, in about a year, will be holographic ‘sprinkles’. To produce these the company dissolves a suitable material, such

    as a carbohydrate or sugar, in liquid and then dehydrates it onto a drum. The drum has a grating pattern engraved on it which is …

    I was told by the MIT museum that Steve Benton was a co-inventor and was involved with the project (he is inventor of white light holography and past head of the holographic division of the media lab)

    It takes half a second to fact check this stuff!
