Some modern methods for food preservation include refrigeration, freezing, canning, vacuum packaging, irradiation, and high-pressure processing. These methods help extend the shelf life of food products by slowing down microbial growth, enzyme activity, and oxidation.
The 2 methods of food preservation is refrigeration and canning

Yes, endothermic reactions can be utilized in the modern refrigeration industry, particularly through processes that involve phase changes or chemical reactions that absorb heat. One example is the use of endothermic chemical reactions in absorption refrigeration systems, where heat is absorbed during the evaporation of a refrigerant. Additionally, solid-state cooling technologies, such as thermochemical refrigeration, exploit endothermic reactions to achieve cooling effects. These methods offer potential for energy-efficient and environmentally friendly refrigeration solutions.

Refrigeration
Most modern systems use a fan to cool the CPU. In some systems, primarily those that have been overclocked, more exotic methods are sometimes used. These include water cooling and even a form of refrigeration. These methods are expensive and quite inappropriate for general use.
In non-cyclic refrigeration, cooling is accomplished by melting ice or by subliming dry ice (frozen carbon dioxide). These methods are used for small-scale refrigeration such as in laboratories and workshops, or in portable coolers. UET TAXILA Mechanical pirates
the modern farming methods are drip system, sprinkler system.
No, refrigeration is not a form of sterilization. While refrigeration slows down the growth of bacteria and other microorganisms, it does not eliminate them. Sterilization, on the other hand, involves processes that completely destroy all forms of microbial life, such as heat sterilization or chemical methods. Refrigeration primarily preserves food by inhibiting microbial activity rather than killing it.
