Food processing is the transformation of agricultural products into food, or of one form of food into other forms. Food processing takes many forms, from grinding grain into raw flour, home cooking, and complex industrial methods used in the making of convenience foods. Some food processing methods play important roles in reducing food waste ...
Pascalization. Pascalization, bridgmanization, high pressure processing ( HPP) [ 1] or high hydrostatic pressure ( HHP) processing[ 2] is a method of preserving and sterilizing food, in which a product is processed under very high pressure, leading to the inactivation of certain microorganisms and enzymes in the food.

In the Eulerian specification of a field, the field is represented as a function of position x and time t. For example, the flow velocity is represented by a function. On the other hand, in the Lagrangian specification, individual fluid parcels are followed through time. The fluid parcels are labelled by some (time-independent) vector field x0.
The group of streamlines enclose the green curves ( and ) to form a stream surface. Streamlines, streaklines and pathlines are field lines in a fluid flow . They differ only when the flow changes with time, that is, when the flow is not steady. [ 1] [ 2] Considering a velocity vector field in three-dimensional space in the framework of ...
The Public Distribution System ( PDS) is a food security system that was established by the Government of India under the Ministry of Consumer Affairs, Food and Public Distribution to distribute food and non-food items to India's poor at subsidised rates. Major commodities distributed include staple food grains, such as wheat, rice, sugar and ...
Food preservation. A food scientist is preparing a meal for astronauts in space. 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 ...
Fluidization. Fluidization (or fluidisation) is a process similar to liquefaction whereby a granular material is converted from a static solid -like state to a dynamic fluid -like state. This process occurs when a fluid ( liquid or gas) is passed up through the granular material. When a gas flow is introduced through the bottom of a bed of ...
A sustainable food system (SFS) is a food system that delivers food security and nutrition for all in such a way that the economic, social and environmental bases to generate food security and nutrition for future generations are not compromised. This means that: It is profitable throughout (economic sustainability);
