would you eat mouldy bread

Fungi are 'decomposers' they make food go bad.
The bacteria and fungi in the food are killed by the heat and can therefore no longer spoil the food.
Because other things than people also like to eat it. Examples are fungi and bacteria. Preservatives suppress their growth making the food edible longer.
water can not preserve food it attracts mold
Fungi have the role of decomposers in the food chain.
Actually fungi cannot produce food while plants can. Fungi can only absorb food from dead organic matter.
Fungi actually don't make their food, they're heterotrophic, or decomposer, even though they have cell walls. You find fungi near their food source.
They get their food from animals and plants
Fungi receives food through filter feeding. It can also just eat bacteria.
On meat, salt can preserve food.
Fungi get into food through contamination - the fungi is allowed to contact the food in some fashion. In the United States, most cross-contamination like this happens in the home after the food has been open. Fungi are pretty much everywhere and for the most part don't hurt anything.
They stuffed the food with salt which would let it dry out and that's how they would preserve it.
well once you have cooked the food it is ready to it so there is no need to preserve it
