Shrimp should be blue if it's frozen raw. If it's been in the freezer for too long it will turn white (that means it's freezer burnt). It's still okay to cook if there are some white bits but I wouldn't cook it if the entire shrimp is white.
All meat can be defrosted and then refrozen. It is safe to eat, but will not be as tasty and juicy if meat had not been frozen. This is not a safety issue but a culinary one.
Defrosted cooked eggplant can be refrozen, but it may affect its texture and quality. If the eggplant was thawed in the refrigerator and has not been left at room temperature for more than two hours, it is generally safe to refreeze. However, for the best taste and consistency, it's recommended to consume it after thawing.
You can refreeze any food after its been defrosted as long as you cook it. What you should never do is defrost food and then freeze it again raw. It's very dangerous to do that.
Yes, after you cook it, it is in a differant STATE, it has been preserved abother way. Just don't freeze it too long.
Defrosted raw meat can be refrozen and cooked later, but the quality of the meat will be notably reduced. If the meat has been at room temperature for more than an hour or so, bacterial growth may have been substantial, and then the refrozen meat may not be safe to eat later, even after being cooked. The best way to deal with defrosted meat that is not needed immediately is to cook it and THEN freeze it for future use. In theory you can defrost and freeze meat as many times as you want as long as you cook the hell out of it before eating. Each time you do it, more bacteria grow inside it, but the heat of cooking will kill them. However, the palatability of the meat decreases with each cycle and quickly renders the food inedibal except by the very hungry.
Cooked shrimp can be left out at room temperature for no more than two hours. After the two hours has passed, you either need to refrigerate the shrimp or throw it away. Shrimp left out on ice will last much longer.
It's never advisable to re-freeze raw meat once it has been defrosted especially sea food - the worse kind of food poisoning is from sea food. Shop bought shrimp are generally safe to freeze immediatly after purchase, but once defrosted, they are exposed to harmful bacteria which can spoil them, and therefore they cannot be refrozen. Defrosted shrimp should be covered and stored in the fridge, and consumed within two days. -The following is from the UK Food Standards agency - http://www.eatwell.gov.uk/asksam/healthydiet/fiasandshellfishq/#A221177 When you buy prawns from a supermarket or fishmonger, they might have been frozen before, even if they aren't frozen when you buy them. Check the label or ask the person serving you, if you're not sure. You shouldn't freeze prawns that have already been defrosted.
No they can not ! not any food that have been defrosted can be re-frosted because of Bactria and germs !If they've been kept refrigerated and well sealed they can be refrozen.
Food which has been cooked can be frozen, even if it was frozen prior to cooking. BUT Frozen food which has been thawed, but not cooked, should never be re-frozen. Nor should food which was cooked, frozen and thawed.
If you are asking "Can chicken that has been frozen be defrosted and cooked?" then the answer is yes. If you are asking if chicken that has been frozen, defrosted, refrozen and defrosted again can be cooked than the answer is yes but it's not safe. When you freeze food water crystals expand and damage cells. When you defrost your food, particularly if you leave it on the counter instead of in the fridge bacteria causing microorganisms have the chance to multiple. When you then refreeze it even larger ice crystals are formed destroying even more cell membranes. After this you defrost it again and the microorganisms from before can double. Usually at this point the meat doesn't look or smell so great.
yes if you put it in the freezer
Yes, frozen cooked shrimp is ready to eat without further cooking as it has already been cooked before being frozen.
