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. 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. 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. For instance, it can reduce the environmental impact of food production.
A dishwasher is a machine that is used to clean dishware, cookware, and cutlery automatically. Unlike manual dishwashing, which relies on physical scrubbing to remove soiling, the mechanical dishwasher cleans by spraying hot water, typically between 45 and 75 °C, at the dishes, with lower temperatures of water used for delicate items.
A washing machine is a machine designed to launder clothing. Modern-day home appliances use electric power to automatically clean clothes. The term is mostly applied to machines that use water as opposed to dry cleaning or ultrasonic cleaners. The user adds laundry detergent, which is sold in liquid, powder, or dehydrated sheet form, to the wash water.

A refrigerator, colloquially fridge, is a commercial and home appliance consisting of a thermally insulated compartment and a heat pump that transfers heat from its inside to its external environment so that its inside is cooled to a temperature below the room temperature. Refrigeration is an essential food storage technique around the world. The low temperature lowers the reproduction rate of bacteria, so the refrigerator reduces the rate of spoilage. A refrigerator maintains a temperature a few degrees above the freezing point of water. The optimal temperature range for perishable food storage is 3 to 5 °C. A freezer is a specialized refrigerator, or portion of a refrigerator, that maintains its contents’ temperature below the freezing point of water. The refrigerator replaced the icebox, which had been a common household appliance for almost a century and a half. The United States Food and Drug Administration recommends that the refrigerator be kept at or below 4 °C (40 °F) and that the freezer be regulated at −18 °C (0 °F).
A deep fryer is a kitchen appliance used for deep frying. Deep frying is a method of cooking by submerging food into oil at high heat, typically between temperatures of 350 to 375 °F.

An icemaker, ice generator, or ice machine may refer to either a consumer device for making ice, found inside a home freezer; a stand-alone appliance for making ice, or an industrial machine for making ice on a large scale. The term "ice machine" usually refers to the stand-alone appliance.
A root cellar, fruit cellar or earth cellar is a structure, usually underground or partially underground, used for storage of vegetables, fruits, nuts, or other foods. Its name reflects the traditional focus on root crops stored in an underground cellar, which is still often true; but the scope is wider, as a wide variety of foods can be stored for weeks to months, depending on the crop and conditions, and the structure may not always be underground.
Sabbath mode, also known as Shabbos mode or Shabbat mode, is a feature in many modern home appliances, including ovens, dishwashers, and refrigerators, which is intended to allow the appliances to be used by Shabbat-observant Jews on the Shabbat and Jewish holidays. The mode usually overrides the usual, everyday operation of the electrical appliance and makes the operation of the appliance comply with the rules of Halakha.

Rice production in South Korea is important for the food supply in the country, with rice being a common part of the Korean diet. In 2009, South Korea produced 3,899,036 metric tonnes of rice.
Rice is the most valuable crop in South Korea. However, as noted by Donald S. Macdonald, rising wage levels and land values have made it expensive to produce. Rice represented about 90 percent of total grain production and over 40 percent of farm income; the 1988 rice crop was 6.5 million tonnes. Rice was imported in the 1980s, but the amount depended on the success of domestic harvests. The government's rice support program reached a record of US$1.9 billion in 1986 compared to $890 million in 1985. By raising procurement prices by 14 percent to the 1986 level, Seoul achieved a rice price structure that was about five times that of the world market in 1987.
Storage of wine is an important consideration for wine that is being kept for long-term aging. While most wine is consumed within 24 hours of purchase, fine wines are often set aside for long-term storage. Wine is one of the few commodities that can improve in flavour and value with age, but it can also rapidly deteriorate if kept in inadequate conditions.
Gimjang (Korean: 김장), also spelled kimjang, is the traditional process of preparation and preservation of kimchi, the spicy Korean fermented vegetable dish, in the wintertime.

For one month, starting from the tenth month of the year, people prepare large quantities of kimchi that will last throughout the winter.
A smart refrigerator, also known as internet refrigerator, is a refrigerator which is able to communicate with the internet. This kind of refrigerator is often equipped to determine itself whenever a food item needs to be replenished. This is still partly managed by human involvement but the next evolution of smart technology is the Intelligent Refrigerator, which incorporates inventory tracking for all items inside, along with a seamless payment system. This involves connecting the refrigerator to an online retail store, ensuring a consistently stocked refrigerator at home for domestic use. For commercial use, additional features such as payment terminals and locks are integrated to manage tasks like unattended retail and queue busting.
