Description

Verfahren zur Aufarbeitung von Abfallprodukten der Sojabohnenölgewinnung Bei der Extraktion von Sojabohnen oder deren Preßkuchen mit Alkohol oder alkoholhaltigen Gemischen erhält man Rückstände, die neben Phosphatiden noch öl, Wasser und Stoffe unbekannter Zusammensetzung enthalten. In dem Hauptpatent 464 554 wurde ein Weg angegeben, um diese Produkte in die technisch wertvollen Einzelbestandteile zu zerlegen. Hierbei erwies sich aber entweder die Entwässerung des Rohproduktes im Vakuum oder die Verwendung erheblicher Mengen von Aceton als nötig.Process for processing waste products from soybean oil production When extracting soybeans or their press cakes with alcohol or alcohol-containing Mixtures result in residues which, in addition to phosphatides, also contain oil, water and substances of unknown composition. In the main patent 464 554 was a way specified in order to break down these products into the technically valuable individual components. Here, however, it turned out either the dehydration of the crude product in a vacuum or the use of significant amounts of acetone than necessary.

Es wurde nun gefunden, daß man diese Rückstände in sehr einfacher Weise auf Produkte aufarbeiten kann, die sich gut als Zusatz zu künstlichen Speisefetten verwenden lassen. Behandelt man nämlich die Rückstände mehrmals mit Alkohol, so entzieht dieser ihnen fast die gesamten Phosphatide, das Wasser und den größten Teil des öles. Vertreibt man nun durch Erhitzen den Alkohol und das Wasser aus den Auszügen, so erhält man zunächst solche Produkte, welche außerordentlich bitter und kratzend schmekken. Durch Nachbehandlung mit wenig Aceton läßt sich jedoch, wie weiter gefunden wurde, ein ölfreies Produkt von neutralem, nußartigem Geschmack erhalten.It has now been found that these residues can be dealt with in a very simple manner Way to work up products that work well as an additive to artificial edible fats let use. If you treat the residues several times with alcohol, so this removes almost all of the phosphatides, the water and the largest from them Part of the oil. If you now expel the alcohol and water from the by heating Extracts produce such products which are extraordinarily bitter and taste scratchy. However, after treatment with a little acetone, as was further found, an oil-free product with a neutral, nutty taste obtain.

Will man nur die unangenehm schmeckenden Bestandteile entfernen, nicht dagegen das -gesamte öl, so genügt es, wenn man nur etwa die ersten zwei alkoholischen Auszüge nach Abdestilheren des Alkohols mit Aceton verarbeitet, da nämlich, wie gefunden wurde, sowohl die bitteren Stoffe als auch die kratzend schmeckenden Bestandteile in die ersten alkoholischen Auszüge wandern, während . die späteren alkoholischen Extrakte nahezu frei von jenen sind.If you only want to remove the unpleasant tasting components, don't on the other hand, the entire oil, it is sufficient if only the first two alcoholic ones are used Extracts processed after distilling off the alcohol with acetone, as namely how was found, both the bitter substances and the scratchy tasting components wander into the first alcoholic extracts while. the later alcoholic Extracts are virtually free from those.

Beispiel i i oo kg eines phosphatidhaltigen, bei der Aufarbeitung von Sojapreßkuchen abfallenden Produktes werden sieben- bis achtmal mit gewöhnlichem Alkohol extrahiert. Nach Abdestillieren des Alkohols ergibt sich ein Rückstand von etwa 55 kg, welcher, mit ioo kg Aceton gewaschen, ein hochprozentiges Phosphatidgemisch darstellt. während aus den Acetonlaugen 2o kg Öl gewonnen werden.Example 100 kg of a phosphatide-containing, in the work-up from soy presscake dropping product are seven to eight times with ordinary Alcohol extracted. After distilling off the alcohol there is a residue of about 55 kg, which, washed with 100 kg of acetone, is a high-percentage phosphatide mixture represents. while 20 kg of oil are obtained from the acetone liquors.

Beispiel e Die beiden ersten der nach dem vorstehenden Beispiel gewonnenen alkoholischen Extrakte werden vom Alkohol befreit und mit Aceton gewaschen. Gibt man hierzu die weiteren alkoholischen Auszüge, so hinterbleiben nach dem Abdes.tillieren des Alkohols 4okg eines etwa 75prozentigen Phosphatidgemisches, während aus dem mittels Aceton gewonnenen Extrakt a o kg öl gewonnen werden können. -_Example e The first two of those obtained according to the previous example Alcoholic extracts are freed from alcohol and washed with acetone. Gives if the other alcoholic extracts are added to this, they remain after the abdes.tillieren of the alcohol 4okg of an approximately 75 percent phosphatide mixture, while from the by means of Acetone obtained extract a o kg of oil can be obtained. -_
