“Tin foil” is divided into two types: tin foil and aluminum foil. The tin foil paper contains metal tin and metal aluminum, aluminum foil paper mainly contains metal aluminum. In terms of appearance, aluminum foil is harder and smoother than tin foil; Tin foil is easy to fold, but also coarser. In barbecue, we often wrap the baking tray or food whole with these two kinds of paper, so as to prevent the grease or other substances in the food from contaminating the cooking utensils, but also to make the food heating more evenly, reducing the part of the burnt and the part of the incomplete heating situation. Wrap the food in these two types of paper/tinfoil and grill it to reduce the aroma of the food and the loss of some substances, and the flavor will be stronger.
History of aluminum foil:
Aluminum foil is the metal aluminum rolled production. The thickness range applied to food packaging is 0.006-0.3mm. Widely used in food packaging, daily necessities, electrical appliances and so on.
At the end of the 19th century and the beginning of the 20th century, the rapid development of aluminum industry in Europe, the emergence of handmade aluminum foil. Aluminum foil was officially produced in Germany in 1911 using the extended pressing process.
Aluminum foil characteristics
Aluminum foil paper uses high purity aluminum, tasteless, non-toxic, food and drug packaging often seen.
Reflective and obvious luster, used in food can add a lot of color.
Compared with other metals, aluminum foil has better heat conductivity, more than three times that of iron. It reflects heat and light very well.
Light can’t penetrate aluminum foil, and neither can moisture or gas. Often used in packaging materials. And it’s easy to print.
So using aluminum foil in the roast will have a good heat conductivity to improve efficiency, and spread more sanitary. No need to clean the baking sheet.
