A conceptual framework for food loss and waste (FLW) [12] Food loss and waste occurs at all stages of the food supply chain – production, processing, sales, and consumption. [13] [12] Definitions of what constitutes food loss versus food waste or what parts of foods (i.e., inedible parts) exit the food supply chain are considered lost or ...
In medicine, wasting, also known as wasting syndrome, refers to the process by which a debilitating disease causes muscle and fat tissue to "waste" away. Wasting is sometimes referred to as "acute malnutrition" because it is believed that episodes of wasting have a short duration, in contrast to stunting , which is regarded as chronic malnutrition.
Food spoilage is the process where a food product becomes unsuitable to ingest by the consumer. The cause of such a process is due to many outside factors as a side-effect of the type of product it is, as well as how the product is packaged and stored.
Organisms use ingested food resources (C=consumption) as building blocks in the synthesis of tissues (P=production) and as fuel in the metabolic process that power this synthesis and other physiological processes (R=respiratory loss). Some of the resources are lost as waste products (F=faecal loss, U=urinary loss).
Climate change causes food waste to increase because the warm temperature causes crops to dry faster and creates a higher risk for fires. Food waste can occur any time throughout production. [201] According to the World Wildlife Organization, [202] since most food produced goes to landfills, when it rots it causes methane to be produced.
Food loss and waste is a major part of the impact of agriculture on climate change (it amounts to 3.3 billion tons of CO 2 e emissions annually [107] [108]) and other environmental issues, such as land use, water use and loss of biodiversity. Prevention of food waste is the highest priority, and when prevention is not possible, the food waste ...
The decomposition of food, either plant or animal, called spoilage in this context, is an important field of study within food science. Food decomposition can be slowed down by conservation. The spoilage of meat occurs, if the meat is untreated, in a matter of hours or days and results in the meat becoming unappetizing, poisonous or infectious.
Food waste may be diverted for alternative human consumption when economic variables allow for it. In the 2019 edition of the State of Food and Agriculture, FAO asserted that food loss and waste have potential effects on the four pillars of food security. However, the links between food loss and waste reduction and food security are complex ...
