How did meats come to be salted?

Are nitrates in kosher hot dogs?

Sodium nitrite is actually the chemical added in hot dogs, not sodium nitrATE. Sodium nitrite is added to pork and other meat products as a preservative to allow it to remain fairly pathogen-free on its way to distant markets. Not all kosher hot dogs are nitrite-free, so you have to look at the ingredients. Most hot dogs have sodium nitrite, though.

The problem with nitrites is that they are converted to nitrosamines in the body...and nitrosamines are very carcinogenic. The simple reason why we don't get cancer after eating a hot dog is because we have DNA repair and regulation mechanisms in our cells that prevent cancers and DNA damage. However, over time, as damage accumulates, those repair mechanisms break down and become less effective, leading to increased probability of cancer.

If power goes out how long does food stay good in refrigerator?

The hard & fast rule is that if a potentially hazardous product is in "the zone" of 40-140f for 4 hours, out it goes. Given that beef is on the list of potentially hazardous items, there really isn't a gray area. Another Answer:That will depend on the temperature of the room, how well the refrigerator is insulated, how often the door is opened and the type of food. Once the temperature of the potentially hazardous food itself (like meat, milk, poultry, seafood, cooked beans, processed produce, etc) has gotten above 40°F for more than 2 hours, the food should be discarded. An unopened refrigerator should be able to hold safe temperatures for 4 hours.

The freezer side of the fridge should keep longer since the temperatures started out lower and that part might be better insulated.

How long can vacuum sealed foods stay frozen and remain edible?

Why hot food stays hot inside a styro-foam?

Styrofoam has a high resistance to heat transfer- that is heat does not "flow" through it very easily. Therefore, heat from the outside air does not enter the container very quickly. This happens because Styrofoam consists of expanded polystyrene. If you looked at Styrofoam under a very strong microscope you'd see millions of tiny pockets in the foam. These pockets trap stagnant air. Air (as long as it's not moving in a current) is very resistant to heat transfer. Hope this helps!

No.

When you chill coffee you condense the moisture in the air in the bag, and draw the condensation out of the beans/grounds.

Cooked food is free from harmful bacteria as the cooking has sterilised it.
