Description
Verfahren zur Umwandlung von Kartoffelstärke in Puddingstärke Die vorliegende Erfindung bezweckt eine weitere Ausgestaltung der den Gegenstand des Patents 629798 bildenden Erfindung eines Verfahrens zur Umwandlung von Kartoffelstärke in Puddingstärke, das darin besteht, daß bei Erwärmung der Stärke ein Feuchtigkeitsgehalt aufrechterhalten wird, der sich aus folgender Zahlentafel ergibt bzw. für die Zwischenwerte errechnet: für 58ºC etwa 5o% Wassergehalt der Stärke in Gewichtsprozenten, für 70°C etwa 35%, für 80°C etwa 3o%, für 90°C etwa 25% und für Ioo° C etwa 2o %, wobei auch in offenen Gefäßen gearbeitet werden kann. Die nun vorliegende weitere Ausgestaltung jenes Verfahrens bezieht sich auf solche Fälle, in denen Kartoffelstärke hoher Viscosität verwendet wird, nämlich solche, deren Erzeugnisse außergewöhnlich stark gummiartig fadenziehend sind. In diesen Fällen sollen gemäß der weiteren Ausgestaltung bei den Feuchtigkeitsgehalten der Stärke, die zwischen 28 und 5o Gewichtsprozenten liegen, Temperaturen angewendet werden, die ungefähr 2 bis 3ºC höher als die oben. angegebenen sind. Die Temperatur wird bei Feuchtigkeitsgehalten bis zu 5o Gewichtsprozenten aufwärts immer zwischen ioo und 58° C zu liegen haben. Die genaue Einstellung der erforderlichen Temperatur ist von Fall zu Fall entsprechend der Beschaffenheit der Kartoffelstärke auszuprobieren. In allen übrigen Beziehungen -also mit Ausnahme der Anwendung der höheren Temperaturen - ist das der weiteren Ausgestaltung entsprechende Verfahren ebenso durchzuführen wie das Verfahren nach der Beschreibung des Patents 629798. Es wird dann die Kartoffelstärke trotz ihrer hohen Viscosität ebenso in Puddingstärke umgewandelt, und :es werden die gleichen Vorteile erreicht wie nach der Beschreibung jenes Patents.Process for converting potato starch into pudding starch The present invention aims at a further embodiment of the invention, which is the subject of patent 629798, of a process for converting potato starch into pudding starch, which consists in maintaining a moisture content, which is shown in the following table of figures, when the starch is heated results or calculated for the intermediate values: for 58ºC approx. 5o% water content of the starch in percentages by weight, for 70 ° C approx. 35%, for 80 ° C approx. 3o%, for 90 ° C approx. 25% and for 100 ° C approx. 20% , it is also possible to work in open vessels. The further refinement of that method now at hand relates to those cases in which potato starch of high viscosity is used, namely those whose products are extraordinarily rubbery and stringy. In these cases, according to the further development, temperatures should be used which are approximately 2 to 3 ° C higher than those above for the moisture contents of the starch which are between 28 and 50 percent by weight. are specified. The temperature will always have to be between 100 and 58 ° C with moisture contents of up to 50 percent by weight. The exact setting of the required temperature must be tried out on a case-by-case basis, depending on the nature of the potato starch. In all other relationships - with the exception of the use of higher temperatures - the method corresponding to the further configuration is to be carried out as well as the method according to the description of patent 629798. The potato starch is then converted into custard starch, despite its high viscosity, and: es the same advantages are achieved as described in that patent.
