- "Food preservation includes processes that make food more resistant to microorganism growth and slow the oxidation of fats." - "This slows down the decomposition and rancidification process."
Examine the various techniques used to preserve food over time, including canning, drying, and curing.
History of food preservation: The various methods of preserving food that have been used throughout history, from ancient times to modern practices.
Microbiology: The study of microbes and their effects on food, including bacteria, yeasts, and molds.
Enzymes: The role of enzymes in food preservation, including how they can be used to break down food and enhance the preservation process.
Food safety: The various safety precautions that must be taken when preserving food, including hygiene, temperature control, and preservation methods.
Canning: The process of storing food in airtight containers to preserve it, including the use of pressure canning and water bath canning.
Pickling: The process of preserving food by immersing it in vinegar, salt, or brine.
Drying: The process of removing moisture from food to extend its shelf life, including air-drying, sun-drying, and dehydrating.
Smoking: The use of smoke to preserve food, including hot and cold smoking.
Fermenting: The process of breaking down food using bacteria or other microorganisms, including sourdough bread, kimchi, and yogurt.
Salting: The use of salt to inhibit the growth of bacteria and preserve food, including the production of cured meats and fish.
Freezing: The use of low temperatures to preserve food, including flash freezing and packing food in airtight containers for long-term storage.
Radiation: The use of ionizing radiation to kill harmful bacteria and extend the shelf life of food.
Refrigeration: The use of low temperatures to slow down the growth of bacteria and extend the shelf life of food.
Additional preservation methods: Other methods of preserving food, including jams and jellies, syrups, and oils.
Food packaging: The various types of packaging used to preserve food, including vacuum-sealed bags, canisters, and jars.
Canning: Involves sealing food in airtight containers and heating them to kill any bacteria or microbes.
Drying: Involves removing moisture from food to prevent bacteria growth, done through sun-drying, oven-drying or dehydration.
Freezing: Involves storing food at extremely low temperatures which slows down bacterial growth.
Fermentation: Is the process of converting sugars into alcohol or acid, often achieved through the use of bacteria or yeast.
Pickling: Involves preserving food in acidic substances such as vinegar or brine.
Smoking: Involves preserving food through the use of smoke and heat, which kills bacteria and adds flavor.
Salting: Involves preserving food by coating it in salt, which removes moisture and prevents bacterial growth.
Sugaring: Involves preserving food by coating it in sugar, which removes moisture and prevents bacterial growth.
Jellying: Involves the use of fruit juices to produce a gelatinous substance to preserve food.
Radiation: Involves using ionizing radiation to preserve food by destroying bacteria, mold, and other microorganisms.
- "By preserving food, food waste can be reduced, which is an important way to decrease production costs and increase the efficiency of food systems." - "Improve food security and nutrition and contribute towards environmental sustainability."
- "Food preservation may also include processes that inhibit visual deterioration, such as the enzymatic browning reaction in apples after they are cut during food preparation."
- "Preserving fruit by turning it into jam, for example, involves boiling, sugaring, and sealing within an airtight jar."
- "Some traditional methods of preserving food have been shown to have a lower energy input and carbon footprint compared to modern methods."
- "Some methods of food preservation are known to create carcinogens." - "In 2015, the International Agency for Research on Cancer of the World Health Organization classified processed meat—i.e., meat that has undergone salting, curing, fermenting, and smoking—as 'carcinogenic to humans'."
