Can baking paper be used to replace fresh film to cover food that should be refrigerated or refrigerated? Professor claims to be safer

I posted on 2023-10-5 Is it harmful to refrigerate with a fresh film? Reader HSU left a message on the same day:

"Please ask the safety material description of baking paper is “ Food-grade silicone oil paper" The baking temperature is usually very high, or it is used to coat cold meat, thank you. ”.

When I searched for Baking paper on Google, almost all the information I found was about Parchment paper, and this term appeared in almost all the titles. Out of curiosity, I used Google to translate Parchment paper, and what I found was "skin paper".

Wikipedia said: "Sheepskin is a material that makes books or provides books, made of sheepskin or calfskin as raw materials. Around 170 BC, Ominis II, the king of Pergamon, the ancient Anatolian country, took the lead in using sheepskin paper. Sheepskin is treated with lime, cut off the wool, and softened with pumice stone, which becomes this new writing material. The English name of sheepskin paper "parchment" comes from the name of this city. '

After a few breaks, I finally figured out that Parchment is really a "skin paper" for book writing, and Parchment paper is a "baking paper" for baking. Parchment paper is mutually exclusive to Baking paper, but Americans almost use Parchment paper.

The information I searched on Google for the most part said that baking paper is safe, but some said that it is unsafe, such as Why I Ditched Unbleached Parchment Paper and Baking Cups. (Note: The reasons for insecurity listed in this article are very strong, and it can be said that there is no need to blame for the crime)

The "unbleached" in this title refers to the fact that the wood used to make baking paper is not bleached. Some information thinks that "unbleached" is safe, while "bleached" is unsafe, but of course, this is also different, and there is no consensus. (Note: "Unbleached" baking paper is yellow-brown, while "bleached" is white) The "food-grade silicone oil paper" in the

Reader HSU refers to baking paper using silicone oil as a slab. "Silicon" is what most Chinese people say. Taiwanese people say "silicon" instead of "silicon". As for why, please check it online by yourself.

I have lived in "Silicon Valley" for more than 40 years, and every time I hear "Silicon Valley" and "Gao Valley" I feel uncomfortable. How well does Silicon Valley match Silicon Valley? Whether it is Silicon Valley or Silicon Valley, they can't compete with Silicon Valley.

Searching in the public medical library PubMed using Parchment paper will result in two related articles, both of which are from the same research team.

2015: Polydimethylsiloxane extraction from silicone rubber into baked goods detected by direct analysis in real time mass spectrometry. Flexible baking molds and other household appliances are made of polydimethylsiloxane (PDMS) (also known as silicone rubber). PDMS tends to release oligomers when they are exposed to fat for a long time, such as during baking noodles.

2016: Detection of polydimethylsiloxanes transferred from silicane-coated purchasing paper to baked goods using direct analysis in real time mass spectrometry. The non-stick properties of baked papers are realized through polydimethylsiloxane (PDMS) smear layers. Therefore, during baking, PDMS can be radiated from baked paper with organic silicon into baked goods.

Polydimethylsiloxane (PDMS, polydimethylsiloxane) in these two papers is commonly known as Silicone liquid, and it is used to provide non-stick chemical layer to bake paper.

These two articles are of course worried that PDMS from food may be harmful to health, but so far, there has been no experiment (cells, animals, humans) that PDMS is harmful to human health.

PDMS has a wide range of uses, including as a replacement for human eye glass. Please see the Physical Characterization and In Vitro Toxicity Test of PDMS Synthesized from Low-Grade D4 Monomer as a Vitreous Substitute in the Human Eyes (Physical Characterization and Exotoxicity Test of PDMS Synthesized from Low-Grade D4 Monomer as a Vitreous Substitute in the Human Eyes).

The article begins with the saying: "PDMS is one of the most high-quality materials and is usually used to replace the damaged human eye glass in glass-based surgery." From this we can see that PDMS is safe.

Of course, I know that putting it in the eyes is different from eating it in the stomach, but most of the information I have read believes that foods baked with baked paper are not harmful to health.
