Although food engineering is a relatively recent and evolving field of study, it is based on long-established concepts and activities. [1] The traditional focus of food engineering was preservation, which involved stabilizing and sterilizing foods, preventing spoilage, and preserving nutrients in food for prolonged periods of time.

Food vs fuel is the debate regarding the risk of diverting farmland or crops for biofuels production in detriment of the food supply on a global scale. Essentially the debate refers to the possibility that by farmers increasing their production of these crops, often through government subsidy incentives, their time and land is shifted away from other types of non-biofuel crops driving up the ...
Food storage and preservation is a key component of food engineering processes and relies heavily on biological engineering to understand and manipulate the organisms involved. Note that the above food safety processes such as pasteurization and sterilization destroy the microorganisms that also contribute to deterioration of food products ...
But the list of environmental costs of food production is a long one: topsoil depletion, erosion and conversion to desert from constant tillage of annual crops; overgrazing; salinization; sodification; waterlogging; high levels of fossil fuel use; reliance on inorganic fertilisers and synthetic organic pesticides; reductions in genetic ...
Demand for meat is expected to double by this date; meat consumption is steadily rising in countries such as China that once followed more sustainable, vegetable-based diets. According to the report: "Impacts from agriculture are expected to increase substantially due to population growth, increasing consumption of animal products.
Political ecology scholars and environmental justice organizations are pointing toward a global environmental justice movement, led by environmental defenders from the global poor. [ 28 ] [ 29 ] Local movements need international support to challenge major trans-national corporations, and environmentalism of the poor would need global influence ...
These are demand-side changes, ecosystem protections, mitigation on farms, and mitigation in supply chains. On the demand side, limiting food waste is an effective way to reduce food emissions. Changes to a diet less reliant on animal products such as plant-based diets are also effective. [34]:
The large environmental impact of agriculture – such as its greenhouse gas emissions, soil degradation, deforestation and pollinator decline effects – make the food system a critical set of processes that need to be addressed for climate change mitigation and a stable healthy environment. A sustainable food system is a type of food system ...
