Canning is an important, safe method for preserving food if practiced properly. The canning process involves placing foods in jars or similar containers and heating them to a temperature that destroys micro-organisms that cause food to spoil.
During this heating process air is driven out of the jar and as it cools a vacuum seal is formed. This vacuum seal prevents air from getting back into the product bringing with it contaminating micro-organisms.
Safe Canning Methods There are two safe ways of processing food, the boiling water bath method and the pressure canner method: The boiling water bath method is safe for tomatoes, fruits, jams, jellies, pickles and other preserves. This temperature can only be reached using the pressure method. A microorganism called Clostridium botulinum is the main reason why pressure processing is necessary.
Though the bacterial cells are killed at boiling temperatures, they can form spores that can withstand these temperatures. The spores grow well in low acid foods, in the absence of air, such as in canned low acidic foods like meats and vegetables.
When the spores begin to grow, they produce the deadly botulinum toxins poisons. Foods that are low acid have a pH of more than 4. The low acidic foods include: meats seafood poultry dairy products all vegetables High acid foods have a pH of 4.
High acidic foods can be safely canned using the boiling water bath method. The high acidic foods include: fruits properly pickled vegetables Certain foods like, tomatoes and figs, that have a pH value close to 4. This is accomplished by adding lemon juice of citric acid. The rack allows the boiling water to flow around and underneath jars for a more even processing of the contents.
The rack also keeps jars from bumping each other and cracking or breaking. If a rack is not available, clean cotton dish towels or similar can be used to pack around jars. If a standard canner is not available any large metal container may be used as long as it is deep enough for l to 2 inches of briskly boiling water to cover the jars.
The diameter of the canner should be no more than 4 inches wider than the diameter of your stove's burner to ensure proper heating of all jars. Using a wash kettle that fits over two burners is not recommended because the middle jars do not get enough heat. For an electric range, the canner must have a flat bottom. Outdoor fire pits with a solid grate will also work however close attention is required to insure proper boiling temperature.
Pressure Canners A pressure canner is a specially-made heavy pot with a lid that can be closed steam-tight. The lid is fitted with a vent or pet-cock , a dial or weighted pressure gauge and a safety fuse. Newer models have an extra cover-lock as an added precaution. It may or may not have a gasket. The pressure pot also has a rack. Because each type is different, be sure to read the directions for operating. Commercial mayonnaise jars, baby food and pickle jars should not be used.
The mouths of the jars may not be appropriate for the sealing lids and the jars are not made with heavy glass and they are not heat treated. Jars come in a variety of sizes from half-pint jars to half-gallon jars. Pint and quart Ball jars are the most commonly used sizes and are available in regular and wide-mouth tops. If properly used, jars may be reused indefinitely as long as they are kept in good condition.
Atlas jars should not be used for home preserving and canning. Jar Lids Most canning jars sold today use a two piece self-sealing lid which consists of a flat metal disc with a rubber-type sealing compound around one side near the outer edge, and a separate screw-type metal band. The flat lid may only be used once but the screw band can be used over as long as it is cleaned well and does not begin to rust.
Canning Utensils Helpful items for home canning and preserving: Jar lifter: essential for easy removal of hot jars. Jar funnel: helps in pouring and packing of liquid and small food items into canning jars. Lid wand: magnetized wand for removing treated jar lids from hot water. Clean cloths: handy to have for wiping jar rims, spills and general cleanup.
Knives: for preparing food. Narrow, flat rubber spatula: for removing trapped air bubbles before sealing jars. Timer or clock: for accurate food processing time. Hot pads Cutting board There are also many specialty utensils available like apple slicers, cutting spoons for coring and pit removal, corn cutters and fruit skinners.
Home Recipes When looking for advice and information on preserving food, try to avoid old pamphlets, outdated cookbooks, untrained celebrities and undocumented food shows on TV. Your best source for current information on research and processing instructions are publications made by the U.
Food and Agriculture Department, College Cooperative Extension Services and major food processing equipment manufactures. For canners, canning equipment and utensils please visit our Canning Equipment eStore.

Ever since man was a hunter-gatherer, he has sought ways to preserve food safely. People living in cold climates learned to freeze food for future use, and after electricity was invented, freezers and refrigerators kept food safe. But except for drying, packing in sugar syrup, or salting, keeping perishable food safe without refrigeration is a truly modern invention. What does "shelf stable" mean?
Can I Still Eat It: How to Safely Store Meat
Accidental freezing of canned foods will not cause spoilage unless jars become unsealed and recontaminated. However, freezing and thawing may soften food. If jars must be stored where they may freeze, wrap them in newspapers, place them in heavy cartons, and cover with more newspapers and blankets. Do not taste food from a jar with an unsealed lid or food which shows signs of spoilage. You can more easily detect some types of spoilage in jars stored without screw bands. Growth of spoilage bacteria and yeast produces gas which pressurizes the food, swells lids and breaks jar seals. Carefully discard any jar of spoiled food to prevent possible illness to you, your family and pets. You must detoxify the container, lid and all the contents before disposal. Follow this process if you suspect spoiled food:.
As the long days of summer arrive, you might imagine yourself carrying overflowing platters of hot dogs and juicy burgers at the next big family cookout.

Each year, 48 million people fall sick from food poisoning, whether in a restaurant or in their own home, estimates the Centers for Disease Control and Prevention. Researchers say it may be anywhere as low as 12 percent to as high as 80 percent. According to the U.
How well seafood is chilled and stored plays a very important part in protecting and maintaining product quality, while limiting the amount of product spoilage. The seafood handling practices involved will differ slightly between commercial and domestic situations. However, regardless of the situation, ice should be used in the chilling and storing of fresh or wet seafood.
Canned fish are fish which have been processed , sealed in an airtight container such as a sealed tin can , and subjected to heat. Canning is a method of preserving food , and provides a typical shelf life ranging from one to five years. Fish have low acidity , levels at which microbes can flourish.SEE VIDEO BY TOPIC: Canning Fish in Cans
It is 85 percent to 95 percent digestible. An average serving furnishes more than enough animal protein to meet the usual daily need for protein. Fish supply 5 percent to 10 percent of the Nation1 s supply of animal protein for human foo requirements. The present work reports the results of the quantitative estimation, made on the same series of samples used in the earlier work, of the sugar and glycogen in the mussel during an annual cycle. Recently, confusion has arisen concerning the suitability of irradiated foods for human consumption.
Seafood Handling and Storage
Another important type of food is seafood , which includes many kinds of fish as well as shellfish and other sea creatures like squid. Some kinds of seafood are raised in ponds or in cages in the sea, but most of the fish we eat are taken alive from the ocean by big commercial fishing boats. Commercial fishing has done a lot of damage by overfishing and by trawling with huge nets that can catch everything, including fish too small to sell and other sea creatures like dolphins. But if you like fishing, don't worry. This sort of damage isn't caused by people who go fishing in small boats or who fish with a fishing rod.
You cannot see, smell, or taste botulinum toxin — but taking even a small taste of food containing this toxin can be deadly. Store home-canned foods external icon for recommended times only. After preparing safely, label and date the jars and store them in a clean, cool, dark place. Can no more food than you will use within one year, unless directions for a specific food give other advice. Before you open a store-bought or home-canned food, inspect it for contamination.

Оказавшись наконец в шифровалке, Сьюзан почувствовала, как на нее волнами накатывает прохладный воздух. Ее белая блузка промокла насквозь и прилипла к телу. Было темно. Сьюзан остановилась, собираясь с духом.
Она загрузила программу Следопыт и, приготовившись отправиться на охоту, взглянула на адрес электронной почты, который вручил ей Стратмор.
Крикливый, тучный, мерзкий немец! - Клушар заморгал, стараясь переменить положение, и, не обращая внимания на боль, продолжал: - Ну чистая скотина, килограмм сто двадцать, не меньше. Он вцепился в эту красотку так, словно боялся, что она сбежит, - и я бы ее отлично понял.
Ей-ей. Обхватил ее своими ручищами.
Бринкерхофф пожал плечами и подошел к окну. - Электроснабжение уже наверняка восстановили. - Он открыл жалюзи. - Все еще темно? - спросила Мидж. Но Бринкерхофф не ответил, лишившись дара речи.
Не могу с ним не согласиться, - заметил Фонтейн. - Сомневаюсь, что Танкадо пошел бы на риск, дав нам возможность угадать ключ к шифру-убийце. Сьюзан рассеянно кивнула, но тут же вспомнила, как Танкадо отдал им Северную Дакоту. Она вглядывалась в группы из четырех знаков, допуская, что Танкадо играет с ними в кошки-мышки.
