Summary

The influence of various factors, like concentration, temperature, additives, etc. on the rigidity of gelatin gels was studied.

The lower the temperature and the higher the concentration of gelatin the higher is the rigidity. A minimum concentration is necessary for gel formation and at 35° practically no rigidity is developed up to a concentration of 35%. Curves for different concentrations demonstrating the effect of temperature seem to converge at 35°C. Salts like sodium chloride, etc. at small concentrations increased the rigidity.

The influence of hydrogen bond favouring agents, depressants, wood extractives, etc. on the rigidity of gelatin gels was investigated and the interesting results reported.

Zusammenfassung

Der Einfluß verschiedener Faktoren wie Konzentration, Temperatur, Zusätze auf die Steifigkeit von Gelatinegelen war Gegenstand von Untersuchungen.

Je tiefer die Temperatur und je höher die Gelatinekonzentration, um so größer ist die Steifigkeit. Für Gelbildung ist eine Minimalkonzentration notwendig, und bei 35°C ist praktisch unterhalb 35% Gelatinegehalt keine Steifigkeit mehr zu erzielen. Kurven für verschiedene Konzentrationen, die diesen Temperatureffekt demonstrieren, scheinen bei 35°C zusammenzulaufen. Salze wie Natriumchlorid usw. bei kleinen Konzentrationen erhöhen die Steifigkeit.

Der Einfluß von Substanzen, die Wasserstoffbindungen begünstigen, „depressants“, Holzextraktionsmittel usw., auf die Steifheit von Gelatinegelen zeigt sich ebenfalls in interessanten Feststellungen.
