Description
Verfahren zum Färben von Nahrungsmitteln Es wurde gefunden, @daß man Nabrungsmittel, insbesondere Gemüse, in. vorteilhafter Weise färben kann, wenn man hierzu Farbstoffe der Triaryhnethanreihe des folgenden allgemeinen Aufbaues verwendet: e worin R eine Oxalkylgrupp.e, Y Halogen oder eine Alkyl-, Oxalkyl- oder Alkoxygruppe und Z einen Arylrest, der noch beliebig substituiert sein kann, bedeuten.Process for coloring foodstuffs It has been found that foodstuffs, especially vegetables, can be colored in an advantageous manner if dyes of the triaryhnethane series of the following general structure are used for this purpose: e where R is an oxalkyl group, Y is halogen or an alkyl, oxalkyl or alkoxy group and Z is an aryl radical which can also be substituted as desired.
Farbstoffe dieser Art kann man beispielsweise nach dem Verfahren der Patentschrift 6o6 078 herstellen. , Sie färben Gemüse gleichmäßig in grünen bis blaugrünen Tönen, die sich auch beim, E-bitzen oder längeren Lagern nicht verändezxi,. Gewünschtenfalls kann man den Farbton noch dadurch etwas :nach Grün verschieben, @dab man kleine Mengen eines gelben oder orangen. Farbstoffs zusetzt.Dyes of this type can, for example, by the method of Manufacture patent specification 6o6 078.

If desired, the color can still be shifted a little: to green, @dab you small amounts of a yellow or orange. Adding dye.
- Beispiel Färben von Erbsen oder Bohnen mit dem Farbstoff vom folgendem Aufbau: hergestellt nach Beispiel q. der Patentschrift 6o6078.- Example of dyeing peas or beans with the dye of the following structure: manufactured according to example q. the patent specification 6o6078.
Ähnlich gute Färbungen erhält man mit Farbstoffen des folgenden Aufbaues; die ebenfalls wach dem Verfahren der Patentschrift 6o6 o78 hergestellt werden können: Similar good colorations are obtained with dyes of the following structure; which can also be produced according to the process of patent specification 6o6 o78:
