The fruit is cooked which kills off most vegetative microbe cells and sugar is added which reduces the water activity which means that most spoilage organisms will not grow in it during storage. But if it is not properly packaged, sealed and stored, yeast and molds could still grow on the food.
Yes, because it must be preserved.
Flora preserved jam every year. The mummy was perfectly preserved. I preserved a petal of the rose in my copy of The Scarlet Letter. The preserved skin tissue helped identify the body.
jam or jelly.
A fossil is always well preserved Please, preserve the strawberry jam. Mummies are well preserved.
No. Jam is not living. It is actually a preserved cooked fruit spread so It is not performing any more life functions.
Preserved means to keep for a long time. If you make jelly or jam from fruit, they are called preserves.
Try freezing or making into jam. Pick out the leaves, twigs and bugs first. Frozen berries can be made into jams and jellies in the winter when things are cooler.
Most jams and jellies are preserved simply by high sugarlevels, which dehydrates and kills microorganisms by pulling water out of their cells by the process of osmosis.
Some examples of preserved foods are pickled onions, salted cod, frozen chicken, tinned sweetcorn, dried apricots, pickles, beef jerky, and strawberry jam.
The contents of the jam jar is usually around 145 grams (i.e. not including the weight of the jar). This is usually because (although jam is a preserve, when it is made industrially it is not boiled to the extent that it would be when homemade, so is less "preserved" than it used to be), jam is not as long-life as it used to be. It is advised that it is kept in the fridge, so a 145g jar is usually the right size to fit in the fridge door.
An advantage of fruit jam would be that it allows the fruit to be preserved and not go bad for an extended period of time. You are able to keep the fruit longer. Another advantage would be that it adds flavor to foods that one might not normally add fruit to. For example, bagels and toast. A disadvantage of fruit jam would be the process of actually making it. It takes much longer to produce then going to the store and buying one prepackaged. Additionally, creating or buying jam would be more expensive then buying a piece of fruit.
It's "well-preserved".
