True/False about food preservation
Every year several tons of food is thrown away all over the world. Many dishes that end up in the trash can still be eaten. How do you find your way around food preservation?
It is recommended to thaw food at room temperature
Fake.Due to the development of bacteria from 5 ° C, it is strongly advised not to thaw food at room temperature. The preferred method for defrosting is the refrigerator. The time required varies depending on the size of the dish and the type of food, and can range from a few hours to an overnight stay. A
microwave is an interesting alternative when you're short on time, as it allows for quick defrosting. It is important to select the correct position and ensure that the container in which the food is placed can fit this type of appliance. It is also possible to thaw tightly closed dishes by immersing them in water for a maximum of two hours. In addition, the temperature should not exceed 21 ° C and the water should be changed every 30 minutes. You have to be very careful:
Food can be stored in the freezer for an indefinite period
forged. Shelf life in the freezer varies depending on each food, but does not exceed one year. The Quebec Department of Agriculture, Fisheries and Food has instituted a perishable food storage charter called Thermoguide 1. Foods that can be stored in the freezer for up to one year include fruits and
vegetables, including asparagus, broccoli, apples, tomatoes and cherries. Salted butter and fresh herbs are also on this list. Meat can be kept for 1 to 10 months depending on whether it is poultry, pork, beef, or another animal. The period also varies depending on whether the piece of meat is cooked or raw. Fish and seafood will be kept for a maximum of 6 months. Lasagna, soup, pie and other ready-made meals have a freezing period of 1 to 10 months.
Leftovers will keep in the refrigerator for 2-3 days.
TRUE. All leftovers can be kept as long as they have been refrigerated for a maximum of two hours after preparing them. This period is reduced to one hour in summer. Contrary to popular thought, dishes can be cooled even if they are still hot. It is recommended to distribute them in several containers with a thickness of about 5 cm (2 in) in order to speed up the cooling process and thus reduce the
multiplication of bacteria. It will then be possible to keep the food for 2 to 3 days in the refrigerator, after which it is better to freeze it. A simple trick for remembering the food preservation process is the following rule: 2 hours -2 inches -2 days 1 .
Dairy products can be frozen
Real.All dairy products can be frozen: milk, butter, cheese, yoghurt (yogurt), cream. Milk, whether pasteurized, sterilized or homogenized, can be stored for up to 6 months in the freezer. If the milk has a high fat content, it is important to stir well before use after defrosting to avoid any sediment that may have formed. Butter can also keep in the freezer for up to 6 months. After this period, his taste qualities
may change. Unlike wet cheeses whose texture will be modified, cheeses with a lower rate of moisture freeze well for up to 6 months. Although it is not dangerous for your health to eat frozen yogurt, its texture will become more lumpy. The cream reacts in the same way as freezing. To restore a smooth texture, simply stroke it gently after defrosting.
The storage time of fresh fruits and vegetables varies with each food
TRUE. Like other perishable foods, fruits and vegetables should be refrigerated between 0°C and 4°C. Shelf life varies from food to food. It can be a few days, between 3 and 5 days, as with cherries, raspberries, asparagus, mushrooms and grapes. Peaches, tomatoes, lettuce, cucumbers, and green
onions, for example, keep in the refrigerator for up to a week. Other foods can be kept for up to two or three weeks. This is the case with cranberries, celery, beets and cabbage. The apple is probably the fruit whose freshness remains the longest 6 months. For a more complete list, it is possible to refer to Thermoguide, Ministry of Agriculture, Fisheries and Food of Quebec.
Always respect the expiration date
forged. In addition to products like flour, sugar, wine, salt, or fruits and vegetables, the majority of foods have an expiration date. The label can actually indicate two types of date: the expiration date of consumption (DLC) and the expiration date of optimum use (DLUO). DLC generally bears the sign "to
consume until..." followed by a specific date. When exceeded, the product may present a health hazard. BBD is rather a reference date, which means that after this period the product may have lost its taste and nutritional qualities without being harmful to health. It is also important to know that the producers/manufacturers are the ones who put the dates on their products themselves after various tests.
