Ethylene gas is produced in most plant tissues and is important in starting off the ripening process. It can be used commercially for the ripening of climacteric fruits. However, natural ethylene produced by fruits can lead to in-storage losses. For example, ethylene destroys the green colour of plants.
Prevention of food waste infers all actions that reduce food production and ultimately prevent food from being produced in vain, such as food donations or re-processing into new food products. Valorisation on the other hand comprise actions that recover the materials, nutrients or energy in food waste, for instance by producing animal feed ...
Among these are plants that have been used for food and other uses on a larger scale historically, but whose usage has dropped in modern times. Reduction in use is due to supply or consumption constraints, poor shelf life , unrecognised nutritional value, poor consumer awareness , and perception as famine food ("poor people's food"), partially ...
Baking bread is an example of secondary food processing. Secondary food processing is the everyday process of creating food from ingredients that are ready to use. Baking bread, regardless of whether it is made at home, in a small bakery, or in a large factory, is an example of secondary food processing. [2]
Plant-based meat is proposed for sustainable alternatives to meat consumption. Plant-based meat emits 30%–90% less greenhouse gas than conventional meat (kg-CO 2-eq/kg-meat) [135] and 72%–99% less water than conventional meat. [136] Public company Beyond Meat and privately held company Impossible Foods are examples of plant-based food ...
Nitrogen fixation from legumes, for example, used in conjunction with plants that rely on nitrate from the soil for growth, helps to allow the land to be reused annually. Legumes will grow for a season and replenish the soil with ammonium and nitrate, and the next season other plants can be seeded and grown in the field in preparation for harvest.
Agriculture encompasses crop and livestock production, aquaculture, and forestry for food and non-food products. [1] Agriculture was a key factor in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in the cities.
The term food system describes the interconnected systems and processes that influence nutrition, food, health, community development, and agriculture.A food system includes all processes and infrastructure involved in feeding a population: growing, harvesting, processing, packaging, transporting, marketing, consumption, distribution, and disposal of food and food-related items.
