So, now that you know the reason behind the different appearance of the two sides, you're probably wondering if you should use aluminum foil with the shiny side up or down. Quite simply, it doesn't matter. Since both sides are made of the exact same material, they will perform exactly the same way.
The shiny side of aluminium foil for cooking food is supposed to be down. Namely, you should have the less shinier said to get contact with food, otherwise food may get stuck on the foil surface during baking, especailly meat.

The Bottom Line
When using standard or heavy-duty foil, you can use either side, shiny or dull. The difference in appearance is due to the manufacturing process and doesn't affect how you use the foil.
So, any time you use a single side foil insulation, the foil needs to be facing toward the living space. So in a loft the foil faces downward.
Lining your oven with foil will actually increase the intensity of heat that will result in surface damage and even go as far as preventing even cooking. So leave it out, invest in an oven-safe cleaning cloth, and enjoy your golden brown cookies, holiday ham, and more!”
Reynold's Kitchen, an aluminium foil manufacturer since 1947, says: "It's perfectly fine to place your food on either side so you can decide if you prefer to have the shiny or dull side facing out." It's simply a result of the manufacturing process. The performance of the foil is the same, whichever side you use.
Tin foil is stiffer than aluminum foil. It tends to give a slight tin taste to food wrapped in it, which is a major reason it has largely been replaced by aluminum and other materials for wrapping food.
I agree with previous answer as the shiny and not shiny part has the same heat conductivity and it does not mean one side had been oxidized more than the other. The difference in shininess is simply a result of manufacturing process.
Yes, aluminum foil can go in the oven. Because aluminum foil is made of metal, when placed in the oven, it heats up and becomes a conductor. It can be used in the oven to cover dishes as they cook or to line pans or baking sheets.
A: The matte side is where you would apply the color or lightener. The shiny side always faces out, to help warm up the foils.
Covered baking typically requires a longer cooking time due to the slower heat transfer.
Aluminum foil's natural non-stick surface aids in easy cookie removal. Monitor baking time closely as cookies may cook faster on foil. Adjust oven temperature down by 10-15 degrees Fahrenheit to prevent overbrowning. Lightly grease foil or use non-stick spray to prevent cookies from sticking.
The answer is that it doesn't matter which side faces up or down when you're cooking with traditional aluminum foil—but if you're working with a specific nonstick variety, which has a protective coating, be sure to use the side recommended by the manufacturer.
Aluminum Foil with Oil: Good for Baking, Especially at Hotter Temperatures. Aluminum foil with oil is another good substitute for parchment paper. As with a greased baking sheet, the fat may subtly impact the way your food cooks. Additionally, there is a chance that some of the food may stick to the pan.
When using aluminum foil in the microwave oven, use small amounts and have it carefully placed. Some general rules: Use new, smooth foil only. Wrinkled foil can cause arcing (sparks).
While aluminum is not magnetic, it can still set off metal detectors due to its electrical conductivity and size. With the right metal detector, like those from PANCKY®️, you can ensure accurate and reliable detection of all metal types, enhancing your security or treasure-hunting experience.
With the exception of non-stick foil, you can cook with aluminum foil shiny side up or down—it will not impact how the food cooks. The difference in appearance is simply a byproduct of the manufacturing process.
Cover dishes
Loosely placing or tenting a sheet of foil over a dish can prevent the top from browning while the rest of your dish continues to bake. If you're looking to create more steam in the baking process, sealing the dish tightly with a foil lid will often do the trick.
Keep in mind that lining your oven with aluminum is not recommended, as it could damage the oven's heating elements. If you're worried about drips or spills, place your dish or item on a sheet pan covered in aluminum foil to avoid mess.
