'It has already been proposed to use canned potatoes Manufacture by watering chopped potatoes and adding sulfuric acid or sulphurous acid.

This type of treatment with The purpose of sulfur dioxide is to
a5 dünne Wasserschutzschicht hindurch die Enzyme nur auf der Oberfläche der rohen Kartoffelstückchen unwirksam zu machen, , die^. Hauptmenge der Enzyme jedoch unverändert abzuschließen. Unmittelbar nach dieser nur ganz kurze Zeit, etwa ι bis 5 Minuten, dauernden Behandlung werden die Kartoffelscheiben oder Schnitzel kräftig abgewaschen, so daß die schweflige Säure gänzlich von ihnen wieder entfernt wird. a 5 thin water-protective layer through it to render the enzymes ineffective only on the surface of the raw potato pieces, the ^. However, the majority of the enzymes complete unchanged. Immediately after this treatment, which lasts only a very short time, about ι to 5 minutes, the potato slices or schnitzel are washed off vigorously so that the sulphurous acid is completely removed from them again.
Zur Ausführung des Verfahrens werden die gereinigten rohen Kartoffeln, geschält oder ungeschält, zunächst zerkleinert, d. h. in Schnitzel oder* Scheiben geschnitten und darauf sofort "; mit Wasser benetzt, um eine dünne Wasserschutzschicht auf ihnen zu bilden, die die Berührung mit der atmosphärischen Luft und die Oxydation verhindert. Die Kartoffelstücke werden dann der Einwirkung des Verbrennungsproduktes einer sehr geringen Menge (etwa ι bis 5 Promille) Schwefel etwa 1 bis 5 Minuten lang ausgesetzt; diese geringe Menge von Schwefeldioxyd macht die Oxydation und Verfärbung mittels der Enzyme unmöglich, ohne in die tiefer liegenden Schichten des Zellgewebes einzudringen und zerstörend zu wirken. Im Anschluß an diese Behandlung mit schwefliger Säure werden die Kartoffelstückchen kräftig mit Wasser abgespült, wodurch die schweflige Säure entfernt wird. Die Behandlung der Kartoffelschnitte mit der schwefligen Säure ' geschieht zweckmäßig auf Horden, auf welchen die Kartoffeln vor und nach der Einwirkung der Säure mit Wasser berieselt werden.

The potato pieces are then exposed to the combustion product of a very small amount (approx ι to 5 parts per thousand) exposed to sulfur for about 1 to 5 minutes; this small amount of Sulfur dioxide makes the oxidation and discoloration by means of the enzymes impossible without to penetrate the deeper layers of the cell tissue and have a destructive effect. in the After this treatment with sulphurous acid, the potato pieces become strong rinsed with water, which removes the sulphurous acid. Treatment of the Potato slices with sulphurous acid are expediently done on trays, on which the potatoes are sprinkled with water before and after the action of the acid. Thereon if there is moderate heat development with the entry of air or in the open air,
