I regularly have it both ways.
But thats for another board.

I thought it was a two-prongued attack: 1) GS displacing conventional heat-sealers, the benefits being reduced energy, improved seal quality, etc. 2) Starpol materials........
IF the oven cook option is currently not satisfied by starpol, you can be certain there will be an RNS at some point in the near future staing that the boys in the back room have cracked it and Starpol 2010 is now undergoing a limited exclusivity period with .......

Are we sure about the oven option? I've not read anything official suggesting it isn't oven-friendly.
If it isn't, ASDA/WM would have known from the start - if they still felt its worth the trials, etc. then I dont see why we should see a problem there. They may have sufficient non-oven (i.e. non-ready made meal applications) to make it worthwhile.
This is how adverse rumours begin!

OB,
All I am going by is the material make-up of the product. I can't find anything that states it is OK at oven type temperatures. Also can't find anything in the SEO info that states the same, so not rumor making, just thinking that if it was cooker friendly they would have mentioned it. I hope I am wrong as obviously this would make for an even better product.
Cheers Greek.

I'm no scientist, and definitely no cook, but..........
If I cook a piece of food then surely the food gets to the same temperature as the oven it is in. Given that the food is in contact with its packaging, the packaging must also reach that temperature. Surely exactly the same applies when microwaving? The oven itself does not reach the temperature, but the food (and by extension) the packaging does?
If you need to cook chicken to X degrees, it matters not the type of oven. the temperature of the chicken, and therefore the packaging, will be the same.
Perhaps someone more familiar with kitchens and less familiar with takeaways will disabuse me of this notion.
I thought it was merely the containers metal content or the type of food that made it suitable for one or the other.

I get pretty firework displays when I microwave meals in metal trays - just adds to the delights I discovered on being divorced!

greek, sorry if you thought I was accusing you of rumour mongering. Absoulutely not. It was just that several people including you had discussed this point and at the oher end I saw a post that indicated that it was now taken as a fact that Starpol couldn't be put in the oven. People could read that and then make another post, etc etc and we don't know if it's fact or fiction in reality. I was accusing all of us. No offence intended.
Alan,
I'm no scientist either but doesn't a microwave work by accelerating and moving the water molecules in the food? Items not containing water, such as plates, containers, etc. dont heat up (except for a little by normal heat transfer from the heated item).

Thats how I understand it oblo. A by-product of the magnatron designed for radar purposes during WW2. That the point. If there were water present in the SEO product, then biodegredation would surely start at manufacture (as this requires moisture and higher temperatures), or it would contaminate the food.
Consensus opinion........buggered if we know.

A microwave oven uses microwaves to heat food. Microwaves are radio waves. In the case of microwave ovens, the commonly used radio wave frequency is roughly 2,500 megahertz (2.5 gigahertz). Radio waves in this frequency range have an interesting property: they are absorbed by water, fats and sugars. When they are absorbed they are converted directly into atomic motion -- heat. Microwaves in this frequency range have another interesting property: they are not absorbed by most plastics, glass or ceramics. Metal reflects microwaves, which is why metal pans do not work well in a microwave oven.
If you put a microwave meal in a convential oven the packaging becomes more stressed and will become distorted to a degree. Fundamentally a microwave meal should be heated only in a microwave oven, otherwise the purpose is wasted.
End of science lesson for today!

OB,
None taken,no problem did not think you did but just wanted to justify my comments (I like you hate the rumor mongers).
Alan,
Not fully right re the food (like you no scientist, even got the litmus test wrong at school). I understand it depends on the molecules, and fat,water content.
As to packaging, if you look at aluminum foil, greaseproof paper for example they get no where near the temp of the food (it's them darn molecules again).
Also as OB states microwaves move the molecules round so only heat created in the food (also as said a bit by heat transfer).
As to Starpol oven qualities, still can't find anything that states it is oven friendly although hope I am wrong.
If anyone knows different, it would make me happier as obviously Starpol would be an even better product than I thought it was.
Kim,
I bet you got the litmus test right as well. Cheers for the tech info.
Only just seen the last couple of posts as it takes me quite a while to type out my posts (useless at science and a techniphobe to boot).

'Morning all
I am going to run a litmus test on SEO and ask them if they know whether their starpol 2000 and maybe 3000 is microwavable without any adverse toxins seeping into the food.
The oily one
I had a litmus test at school and failed.
It was for intelligence!

Oilywag,
It is microwave friendly with no adverse toxins seepage, re the FDA approval which looked into all contact with food matters, including heating etc.

Alan et. al,
I'm no scientist, but am an engineer. My take on the oven question is: Conventional oven cooking is reliant on heat transfer, from the surface to the core, the bigger the difference between the external and internal temperature the higher the heat transfer. I assume that one cannot heat the core for too long at or above water boiling point as this will result in a hard, dry lump.
So the key to oven cooking is to heat the core to say ~100 degrees for a period of time. Also, for textue and aesthetics, a degree of roasting/browning may be required which would need a high surface temperature.
Microwaving is more efficient and results in a lower external temprature but generally result in anemic chicken etc..
A bit garbled but hope it makes some sense.

Thanks gary - but does Starpol explode and burn the house down when put in an oven or will chicken tika masala eaters the world over be safe?
Thats the question for today!
Can all ready made meals (currently) be put in both MW and conventional ovens?
