Does Ejiao cake harden when it is cold? What should I do if the Ejiao cake hardens?
First of all, Ejiao belongs to colloidal food, and its main component is collagen. Collagen is easy to form gel state at low temperature, which leads to the hardening of Ejiao cake. However, a variety of seasonings and carbohydrates will be added when making Ejiao cake, which can increase the surface tension of Ejiao cake, reduce the formation of gel and make it have certain cold resistance.
Secondly, the processing technology of Ejiao cake also determines its hardness. It is necessary to control the proportion of donkey-hide gelatin and other ingredients, as well as the heating time and temperature. If there is too much donkey-hide gelatin or the heating temperature is too high, the donkey-hide gelatin cake will become particularly hard. Conversely, if there is too little donkey-hide gelatin or the heating temperature is too low, the donkey-hide gelatin cake will become too soft.
To sum up, when the weather gets cold in winter, Ejiao cakes sometimes harden. But this is not absolute, because surface tension and manufacturing technology have certain effects on preventing hardening. If Ejiao cake hardens in winter, we can take the following measures.
What should I do if the Ejiao cake hardens? The best hardening method of Ejiao is heating. After heating, collagen in Ejiao can be dissolved into colloid again, which makes Ejiao cake restore its original soft and waxy taste.
Pay attention to the following points when heating:
Ejiao cake is cut into small pieces or thin slices, which is convenient for heating evenly. It can be heated by microwave oven or steamer, and the time should not be too long, so as to avoid overheating and losing the taste of Ejiao cake. If you don't have a microwave oven or steamer at hand, you can also blanch it with boiling water, add a little hot water and gently stir it to restore the soft and waxy taste. In addition, you can also add some liquids, such as milk, soybean milk, juice and so on. After heating, it can make the Ejiao cake taste richer and increase its nutritional value.
In a word, Ejiao cake will harden in cold weather, which is caused by collagen coagulation at low temperature. However, the choice of manufacturing technology and components can increase its cold resistance. If the Ejiao cake hardens, it can be restored to soft and waxy taste by heating and adding liquid.
