The word pasteurization is derived from the name of an eminent French scientist Louis Pasteur (1860), who found that heating certain liquids specially wines to a high temperature improved their keeping quality. Lund. Dry Heat Sterilization 5. Seeds can more or less resist such deleterious effect due to the presence of its seed coat. The basic principle behind the tests for sterility is that, whenever a microorganism is provided with a nutrient medium, suitable temperature and pressure, it grows and multiples, which can be visible as a turbidity or as a colony on the culture media. The steam vibrations destroy the microorganisms. [This chapter from a classic textbook series instructs college students majoring in food science on the scientific principles of food preservation by heat sterilization, and describes how times and temperatures in thermal processing of canned foods are determined].

A large percentage of steam sterilizer failures can be solved by logical and practical application of these basic principles. Agar media on prolonged sterilization, heating or repeated melting are apt to show a precipitate. Basic Principles of Sterilisation by Heat: Moist heat is more effective than dry heat by sterilising at a lower temperature in a given time, or in a shorter time at a given temperature. Dry heat sterilization is used on equipment that cannot be wet and on material that will not melt, catch fire, or change form when exposed to high temperatures.
