Title: Process for encapsulating food substances and fat-encapsulated food substance itself
IPC: A23P10/35
Filed: 1981-09-10
Abstract: The present invention is aimed at a process for encapsulating food substances. Whereas hitherto, fluidised bed processes have sometimes been used for this purpose or the coating has been completely dispensed with since the desired result is not achieved, according to the invention a certain amount of fat is first dissolved in a solvent into which the substance to be encapsulated is then added, whereupon the solvent is then completely removed by vacuum. According to the invention, a so-called vacuum mixing apparatus is used for this which has only been used hitherto in the purely chemical area. The process according to the invention in this case is not only simple and economical but also delivers the desired, equally thick fat encapsulation of various food substances.
