By freezing food before the use by date will allow you to enjoy some of your perishable items past the use by date. However you cannot store food indefinitely, frozen food can go bad after a while and obtain freezer burn.
Date marking frozen food is not necessary when the food will be eaten before its expiration date. The process of freezing food prolongs its life but does not allow it to be stored indefinitely.
Date marking is necessary when freezing foods. Foods will spoil in a freezer also.
It is still necessary to mark frozen food with the dates. Freezing extends the shelf life, but there will still be some deterioration of the food in the freezer, so FIFO rules still apply.
Placing a date upon food is a legal standard from the Food and Drug Administration (FDA). While there are some arguments to whether or not this is necessary scientific research has shown that some food decay takes place even at low temperatures.
I would not say it is not necessary, because it is - just not required by United States law. You still need it for FIFO rotation. Frozen foods do deteriorate, but not at the rate of their refrigerated kin.
The scale is either Fahrenheit degrees or centigrade (Celsius, Kelvin) degrees. The Fahrenheit scale has 180 equal degrees between the freezing point of water (32°F) and the boiling point (212°F). On the Celsius scale, there are 100 equal degrees between these points (0°C to 100°C).
It does help when you can write up your experiment and with the marking when it's understandable.
because there marking there territory
Both Celsius and Fahrenheit are suitable for temperature control, but Celsius is more commonly used in scientific applications and in most countries worldwide. Celsius is easier to understand in terms of the freezing and boiling points of water, with 0°C marking the freezing point and 100°C marking the boiling point.
0 degrees Celsius is considered cold. It is the freezing point of water, marking the temperature at which water turns to ice.
marking system is better than grading system because for intell students
Because of new instruments :)
