The food industry is a complex global network of diverse companies that supplies most of the food consumed by the world's population. The term food industries encompasses a series of industrial activities aimed at the production, distribution, processing, conversion, preparation, preservation, transportation, certification and packaging of food products. Nowadays, the food industry has become very diversified, and manufacturing ranges from small, traditional and family activities that require a lot of labor, to large, capital-intensive and highly mechanized industrial processes. Many food industries are almost completely dependent on local agriculture, agricultural products, or fishing.
The food and beverage industry includes all companies involved in the transformation of raw agricultural products into consumer food products. Within the food industry, all farmers are considered part of the industry, excluding only subsistence farmers. This number only includes foods that are sold in the United States, not those that are marketed and exported abroad. In the food industry, the property of having a high catalytic activity at a low temperature allows the transformation of thermolabile products.
The food industry refers to a complex global industry that brings together many small and large scale industries or businesses related to the production, processing, supply and distribution of food products. A Finnish study found that chronic rhinitis is common among slaughterhouse and convenience food workers (30%), factory and bakery workers (26%) and food processing workers (23%). Infections and infectious or parasitic diseases transmitted by animals or animal waste products used in manufacturing are common occupational problems in the food industry. Extensive studies are needed to optimize the production of cellulose suitable for food use in SSF, taking into account that this type of process provides greater productivity due to high levels of enzyme performance and shorter fermentation times.
With the help of other microorganisms, other products can be produced, such as lactic acid, an important raw material for the food and pharmaceutical industries, or citric acid, which the food industry needs in large quantities. Because there are many different types of food processing, the machines used can exert very different operating tensions on bearings and similar components. Many of the plants that process meat, poultry, fish and food involve very repetitive and energetic work. And it must do so cleanly and in accordance with regulatory requirements, just like the food production equipment itself.
As food retailers have consolidated, the sector has attracted the interest of academics interested in market organization and regulatory agencies concerned with fair trade practices. The frozen food industry uses all methods to freeze fresh food at temperatures below its freezing point, thus forming ice crystals in aqueous tissues.
