Yes

what is the lowest temprature, that still kill all microbes?

Separate questions. In a microbiology lab, the standard sterilization
temperature is 121 degrees Celsius. Pressure canners usually are no
more than 115 or so Celsius.

Holding temperature? Acidic foods will do better. It depends on the
food, the holding time, and the level of safety desired.

There are disposable liners made for slow cookers. They are some type
of
polymer.

Slow cookers condoms!!

Exactly!

For that matter, you can use Reynold's oven bags in your slow cooker, and
they're probably cheaper and easier to find. That should solve your
"contamination" problem, as well as provide easier cleanup.

Isn't the "hot food hot" temperature 140 F?

Below 40F and above 140F or below 4C and above 60C

what is the lowest temprature, that still kill all microbes?

All? I'm not sure, but most food bacteria starts to die at about 145F and
most are gone by about 160F but I'm not a food scientist so I may be off a
few degrees.

If you are still worried about the ceramic,

You could put yourself in a giant zip lock bag.

I want to prepare my food according to the principle of low
heat/slow cooking. Especially broth.

Oven - dosn't have less then 100 degree celsius, and dries food too
much.
simmer - food is still bubbling (boiling).
So I thought maybe electrical slow cooker will suit.

But there is a problem of what the inner bowl is made of. Since
acidic foods (like broth) increase the risk of leaching lead and
other metals.

The slow cookers I saw so far are made from either ceramics,
ceramics+colored glaze or stoneware/pottery. All of them can leach
lead and/or aluminum silicate and such conditions.
I know glass conduct heat less good then ceramics. but I prefare this.
So my question is: do you know of a slow cooker which its internal
bowl is made of clear glass or at least the glaze is from clear glass?
If you do, please write me the name of the brand/firm or if you have
a link.


What makes you think that glass is any safer? Even clear glass can
contain lead and other metals.

thanks. DO you know of an actual brand name that have slowcooker with a

The one I saw were black, red, brown etc.

I wrote yesterday that I had my doubts about whether white slow cookers
existed, and then this morning in the Sunday newspaper advertising flyers I
see two slow cookers in white!

The first one I saw was in a Target (www.target.com) ad, for one made by
Rival. Then I looked at the K-Mart (www.kmart.com) ad, and saw one made by
Hamilton Beach. So white ones do exist.

Rival products are at www.rivalproducts.com. They make many, but an example
of a white one is at:
http://www.rivalproducts.com/eStore/...ProductId =78

Hamilton Beach products are at www.hamiltonbeach.com. An example of a white
one from them is at:
http://www.hamiltonbeach.com/kitchen...ers/33163.html

Rival has an extensive selection of replacement crocks for their slow
cookers, many of them in white.

I'm not sure if any of this is useful, as you might not be in the USA...
since you referenced a temperature in Celsius! These brands and stores might
not be where you live.

Aside from the fact that these slow cookers come in white, I can't vouch for
the quality or usefulness of these brands. But Rival is the maker of the
original "Crock Pot" and has the trademark to that name. They also have a
web site called www.crockpot.com.

you are right! I'm definitely not sure about clear glass either. I just
want to cook food (for an autistic child, which was found to be have
high levels of heavy metals in its body) in the *safest* material that
is known.
If someone knows about safer materials, I would be grateful to hear.

Stainless steel.

It is full of chromium. And we found out from Erin Brokovitch that
chromium six is deadly and will make you very ill. so don't lick bumpers
and stay away from Stainless Steel.

But, is it inert or does the metal leach into the food? I think it is the
former.

And glass is full of silica. Maybe the OP should just eat it raw out of
his hands. Zeesh!

But what if the OP used soap on his hand and some of the residue was
ingested? That might cause all sorts of problems, I'm sure.

That might be okay, Vox. He could probably use a good cleaning out.

Well, it is probably organic, natural soap made by a lost tribe in the
southwestern Andes. Except for some llama dung....
