Description
Verfahren zur Verhinderung der bei der Zubereitung von Kartoffeln, Obstoder Gemüsen auftretenden Mißfärbungen Bekanntlich tritt bei geschälten Kartoffeln, wenn diese zerkleinert werden, alsbald eine dunkle Mißfärbung auf, und zwar um so stärker, je länger die Kartoffelmasse an der Luft steht bzw. je älter die verwendeten Kartoffeln sind.Method of preventing the in the preparation of potatoes, Discoloration of fruit or vegetables is known to occur in peeled potatoes, when these are crushed, a dark discoloration immediately appears, and all the more so stronger, the longer the potato mixture is in the air or the older the potatoes are used Are potatoes.
Gemäß Patent 8o6 54.o ist bereits vorgeschlagen, durch Zugabe sehr geringer Mengen Metabisulfit oder Sulfit des Natriums oder Kaliums oder von Gemischen aus diesen Salzen diese Mißfärbungen zu verhindern bzw. zu beseitigen.According to patent 8o6 54.o is already proposed by adding very small amounts of metabisulphite or sulphite of sodium or potassium or of mixtures to prevent or eliminate this discoloration from these salts.
Wie weiter gefunden wurde, sind noch einige andere chemische Körper geeignet, diese Wirkung zu erzielen., und zwar sind dies sulfurierte oder chlorierte Abkämmlinge des Toluols und Benzols, vorzugsweise Paratoluolsul,fochlorami.dnatrium und Ben!zol.sulfonchloramidnatrium oder -kalium.As was further found, there are several other chemical bodies suitable to achieve this effect. These are sulfurized or chlorinated Comes from toluene and benzene, preferably paratoluene, fochlorami.dnatrium and benzene sulfonchloramide sodium or potassium.
Ausführungsbeispiel Das geschabte Fleisch von 2 kg rohen Kartoffeln wird mit o,5 g Paratoluolsulfochlorami@dnatrium versetzt und gut verrührt. Die bereits während des Reibens der Kartoffel eingetretene dunkle Mißfärbung der Kartoffelmasse wird dadurch sehr schnell aufgehellt und beseitigt. Die Kartoffelmasse kann wie üblich weiterverarbeitet werden.Exemplary embodiment The scraped meat from 2 kg of raw potatoes is mixed with 0.5 g of paratoluene sulfochlorami @ disodium and stirred well. The already dark discoloration of the potato mass that occurred during the grating of the potato is thereby brightened and eliminated very quickly. The potato mass can like are usually further processed.
