Discuss two non-thermal conditions that allows a chemical reaction to occur
Answers
Non-thermal technologies (NTP) are processing methods for achieving microbial inactivation without exposing foods to adverse effects of heat whilst extending product shelf life and retaining their fresh-like physical, nutritional, and sensory qualities.
Foods can be non-thermally processed by (1) cold plasma, (2) high hydrostatic pressure (HHP), (3) microwave and radio-frequency and (4) dense phase carbon dioxide, among other techniques. ... Each non-thermal technology has specific applications in terms of the type of food processed.
hope it helps you
Explanation:
Processing of foods without the application of heat is termed as the non-thermal processing. The most widely used non-thermal processing techniques are high pressure processing, pulsed electric field, ultrasound, pulsed light, ultraviolet light, irradiation, oscillating magnetic field etc.
