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.
Food irradiation is the process of exposing food and food packaging to ionizing radiation, such as from gamma rays, x-rays, or electron beams. Food irradiation improves food safety and extends product shelf life (preservation) by effectively destroying organisms responsible for spoilage and foodborne illness, inhibits sprouting or ripening, and is a means of controlling insects and invasive pests.
Vegetable farming is the growing of vegetables for human consumption. The practice probably started in several parts of the world over ten thousand years ago, with families growing vegetables for their own consumption or to trade locally. At first manual labour was used but in time livestock were domesticated and the ground could be turned by the plough. More recently, mechanisation has revolutionised vegetable farming with nearly all processes being able to be performed by machine. Specialist producers grow the particular crops that do well in their locality. New methods—such as aquaponics, raised beds and cultivation under glass—are used. Marketing can be done locally in farmer's markets, traditional markets or pick-your-own operations, or farmers can contract their whole crops to wholesalers, canners or retailers.
Lettuce is an annual plant of the family Asteraceae mostly grown as a leaf vegetable. The leaves are most often used raw in green salads, although lettuce is also seen in other kinds of food, such as sandwiches, wraps and soups; it can also be grilled. Its stem and seeds are sometimes used; celtuce is one variety grown for its stems, which are eaten either raw or cooked. In addition to its main use as a leafy green, it has also gathered religious and medicinal significance over centuries of human consumption. Europe and North America originally dominated the market for lettuce, but by the late 20th century the consumption of lettuce had spread throughout the world. As of 2021, world production of lettuce was 27 million tonnes, 53 percent of which came from China.
Food storage is a way of decreasing the variability of the food supply in the face of natural, inevitable variability. It allows food to be eaten for some time after harvest rather than solely immediately. It is both a traditional domestic skill and, in the form of food logistics, an important industrial and commercial activity. Food preservation, storage, and transport, including timely delivery to consumers, are important to food security, especially for the majority of people throughout the world who rely on others to produce their food.
Dole plc is an Irish-American agricultural multinational corporation headquartered in Dublin, Ireland. The company is among the world's largest producers of fruit and vegetables, operating with 38,500 full-time and seasonal employees who supply some 300 products in 75 countries. Dole reported 2021 revenues of $6.5 billion.
A market garden is the relatively small-scale production of fruits, vegetables and flowers as cash crops, frequently sold directly to consumers and restaurants. The diversity of crops grown on a small area of land, typically from under 0.40 hectares to some hectares, or sometimes in greenhouses, distinguishes it from other types of farming. A market garden is sometimes called a truck farm in the US.
In agriculture, postharvest handling is the stage of crop production immediately following harvest, including cooling, cleaning, sorting and packing. The instant a crop is removed from the ground, or separated from its parent plant, it begins to deteriorate. Postharvest treatment largely determines final quality, whether a crop is sold for fresh consumption, or used as an ingredient in a processed food product.
Fresh Del Monte Produce Incorporated is one of the world’s leading vertically integrated producers, distributors, and marketers of fresh and fresh-cut fruits and vegetables. Their products include prepared fruit and vegetables, juices, beverages, snacks, and desserts, and are sold in more than 90 countries around the world.
Vegetables are parts of plants that are consumed by humans or other animals as food. The original meaning is still commonly used and is applied to plants collectively to refer to all edible plant matter, including the flowers, fruits, stems, leaves, roots, and seeds. An alternative definition of the term is applied somewhat arbitrarily, often by culinary and cultural tradition. It may exclude foods derived from some plants that are fruits, flowers, nuts, and cereal grains, but include savoury fruits such as tomatoes and courgettes, flowers such as broccoli, and seeds such as pulses.
Vacuum packing is a method of packaging that removes air from the package prior to sealing. This method involves placing items in a plastic film package, removing air from inside and sealing the package. Shrink film is sometimes used to have a tight fit to the contents. The intent of vacuum packing is usually to remove oxygen from the container to extend the shelf life of foods and, with flexible package forms, to reduce the volume of the contents and package.
Modified atmosphere/modified humidity (MA/MH) packaging is a technology used to preserve the quality of fresh produce so that it can be sold to markets far away from where it is grown, extend the marketing period, and to help suppliers reduce food waste within the cold chain. Commercial examples of MA/MH include sea freight of Galia and cantaloupe melons from Central and South America to Europe and North America ; transport of white asparagus from fields in Peru to markets in Western Europe ; and trucking of cherries from orchards in Turkey to supermarkets in the UK.
Adulteration is a legal offense and when the food fails to meet the legal standards set by the government, it is said to have been Adulterated Food. One form of adulteration is the addition of another substance to a food item in order to increase the quantity of the food item in raw form or prepared form, which results in the loss of the actual quality of the food item. These substances may be either available food items or non-food items. Among meat and meat products some of the items used to adulterate are water or ice, carcasses, or carcasses of animals other than the animal meant to be consumed. In the case of seafood, adulteration may refer to species substitution (mislabeling), which replaces the species identified on the product label with another species, or undisclosed processing methods, in which treatments such as additives, excessive glazing, or short-weighting are not disclosed to the consumer.
Produce traceability makes it possible to track produce from its point of origin to a retail location where it is purchased by consumers.
Raw meat generally refers to any type of uncooked muscle tissue of an animal used for food. In the meat production industry, the term ‘meat’ refers specifically to mammalian flesh, while the words ‘poultry’ and ‘seafood’ are used to differentiate between the tissue of birds and aquatic creatures.
Post-harvest losses of vegetables and fruits occur at all points in the value chain from production in the field to the food being placed on a plate for consumption. Post-harvest activities include harvesting, handling, storage, processing, packaging, transportation and marketing.
Biopreservation is the use of natural or controlled microbiota or antimicrobials as a way of preserving food and extending its shelf life. The biopreservation of food, especially utilizing lactic acid bacteria (LAB) that are inhibitory to food spoilage microbes, has been practiced since early ages, at first unconsciously but eventually with an increasingly robust scientific foundation. Beneficial bacteria or the fermentation products produced by these bacteria are used in biopreservation to control spoilage and render pathogens inactive in food. There are a various modes of action through which microorganisms can interfere with the growth of others such as organic acid production, resulting in a reduction of pH and the antimicrobial activity of the un-dissociated acid molecules, a wide variety of small inhibitory molecules including hydrogen peroxide, etc. It is a benign ecological approach which is gaining increasing attention.
Liquid manure is a mixture of animal waste and organic matter used as an agricultural fertilizer, sometimes thinned with water. It can be aged in a slurry pit to concentrate it.
Food safety in the United States relates to the processing, packaging, and storage of food in a way that prevents food-borne illness within the United States. The beginning of regulation on food safety in the United States started in the early 1900s, when several outbreaks sparked the need for litigation managing food in the food industry. Over the next few decades, the United States created several government agencies in an effort to better understand contaminants in food and to regulate these impurities. Many laws regarding food safety in the United States have been created and amended since the beginning of the 1900s. Food makers and their products are inspected and regulated by the Food and Drug Administration and the Department of Agriculture.
