What the expert says

Serena Pironi begins by saying that when using any product it is important to carefully read the label , a detail that is often overlooked by most consumers. The label contains important information on the use of parchment paper, such as " do not use at temperatures above 220 degrees ". In fact, according to the expert, “parchment paper normally retains its integrity up to 220 ° C. Beyond this temperature, disintegration phenomena could occur and, as a result, the disintegrated molecules would mix with the food. ". Serena Pironi also points out that if the paper is used in the microwave, “ the maximum temperature tolerated is 150 ° C “.
