1. Define the following:
- a. Botulism
- is a rare but serious paralytic illness caused by a nerve toxin, botulin, that is produced by the bacterium Clostridium botulinum. Foodborne botulism is caused by eating foods that contain the botulism toxin. Outbreaks of foodborne botulism are usually caused by eating contaminated home-canned foods.
- b. Steam pressure canning
- is a method of canning by placing the food in a pressure cooker. A pressure cooker allows water to be heated to a temperature higher than the "standard" boiling point of 212°F (100°C).
- c. Boiling water bath
- d. Steam canning
- e. Open kettle canning
- f. Pectin
- Under acidic conditions, pectin forms a gel, and it can be used as an edible thickening agent in processed foods. This effect is used for making jams and jellies.
- g. Hot pack
- Food is packed into jars after being cooked and while still hot. It is then placed in a pressure cooker.
- h. Cold pack
- Food is packed into jars in an uncooked state (or sometimes after being scalded). It is then placed in a pressure cooker.
- i. Sterilize
- Killing all forms of bacteria and other pathogens present on an item (such as a jar).
- j. Scald
- Immersing a fruit or vegetable in boiling water for a minute or two. This splits the skin, easing the task of removing the peel.
- k. Jelly
- A jelly is a sweet or savoury food gel, usually made through the addition of gelatin or pectin to edible liquids. "True" jellies are smooth textured and made from fruit juice, such as grape jelly.
- l. Jam
- is a type of sweet spread or condiment made with certain fruits or vegetables, sugar, and sometimes pectin. In the United States and Canada, jams are invariably made from mashed or ground fresh fruits.
- m. Marmalade
- invariably refers to a conserve derived from a citrus fruit, most commonly from oranges. The recipe includes sliced or chopped fruit peel, which is simmered in fruit juice and water until soft; indeed marmalade is sometimes described as jam with fruit peel.
- n. Pickles
- Pickling is the process of preparing a food by soaking and storing it in a brine containing salt, acid (usually vinegar), or both, a process which can preserve otherwise perishable foods for months. The resulting food is called a pickle.
