Now, 'revolutionary' 3D printer can print 'fruits'

A UK-based company has invented what they are calling the 3D Fruit Printer - a machine that "prints" three-dimensional "fruits".

The fruit is not, however, actual fruit and instead is a sort of reconstituted version which can be any flavor, CNET reported.

The printer makes use of a molecular gastronomy technique called spherification to convert liquid to gelatinous globules that resemble caviar or tapioca pearls.

For fruit juice, this means mixing the juice with alginic acid, which is then dripped into a cold bath of calcium chloride. The resultant reaction produces a skin around it which pops when it is bitten into.
