Aluminum foil paper is the perfect kitchen item for grilling, using the oven, and keeping things warm and fresh. But how to use aluminum foil properly? Shiny side up or down? How do you prevent food from sticking to it? In this article, we will introduce you to the difference between the two sides of aluminium foil.
Aluminium Foil Shiny vs Dull Side
Aluminum paper shiny side reflectivity is 88% and dull side is 80% . Therefore, the shiny side reflects more heat, and when the shiny side is up and touching the food, the food will heat up faster. The difference in reflectivity between the two sides is not that big, so it is fine to use the dull side up.
When using aluminium paper for barbecuing, the barbecuing process relies on conduction of heat rather than radiation, so whichever side of the foil is up does not have much effect.
But some people still have doubts about the glossy side up or down. In most cases, you can choose the correct side of the foil paper according to your needs and purpose of use. Here are some suggestions:
Cooking and Baking: If using aluminum foil paper for cooking or baking, the shiny side should be up, touching the baking sheet. This is because the shiny side reflects heat and helps the cooking to be successful.
Freezing and Wrapping: if you use aluminum foil for freshness or wrapping, choose either the bright side up or down. This is because glossy and matte surfaces have similar thermal conductivity.
How To Wrap Grilled Fish In Aluminum Foil
As we all know, baked fish is easy to stick. As a professional aluminum foil baking wrapper manufacturer, we teach you how to use foil wrappers to bake fresh, non-stick baked fish.
- Line a baking sheet with aluminum foil.
- Crumple up a second sheet of foil, unroll it, and place it on top of the first sheet, keeping the bumps as even as possible.
- Place your fish on the second foil.
During the grilling process, the fish will produce moisture and oil, which will cause the fish skin to stick. After the aluminum foil is crumpled, the uneven surface can reduce the contact between the fish skin and the aluminum foil, which not only avoids adhesion but also allows the bottom of the fish to have gaps and a high degree of retention of moisture and oil, keeping the fish skin dry.
Acidic Food Contact Aluminium Foil
When aluminum foil comes into contact with acidic food and is baked at high temperature, aluminum will be precipitated. Although the body’s metabolic function can excrete trace amounts of aluminum, we still need to try to avoid it.
To avoid aluminum precipitation, you need to add seasoning after the food is cooked and the aluminum foil is removed. If the aluminum foil has scratches or flaws, it should be replaced immediately.
