Methods of fermentation include, but are not limited to, starter microorganisms, salt, hops, controlled (usually cool) temperatures and controlled (usually low) levels of oxygen. These methods are used to create the specific controlled conditions that will support the desirable organisms that produce food fit for human consumption.

Low-temperature cooking is a cooking technique that uses temperatures in the range of about 60 to 90 °C (140 to 194 °F) [1] for a prolonged time to cook food. Low-temperature cooking methods include sous vide cooking, slow cooking using a slow cooker, cooking in a normal oven which has a minimal setting of about 70 °C (158 °F), and using a combi steamer providing exact temperature control.
Pasteurized milk in Japan A 1912 Chicago Department of Health poster explains household pasteurization to mothers.. In food processing, pasteurization (also pasteurisation) is a process of food preservation in which packaged foods (e.g., milk and fruit juices) are treated with mild heat, usually to less than 100 °C (212 °F), to eliminate pathogens and extend shelf life.
Salt tolerance of crops is the maximum salt level a crop tolerates without losing its productivity while it is affected negatively at higher levels. The salt level is often taken as the soil salinity or the salinity of the irrigation water.
Tomatoes keep best unwashed at room temperature and out of direct sunlight, rather than in a refrigerator. [95] [96] Storing stem down can prolong shelf life. [97] Unripe tomatoes can be kept in a paper bag to ripen. [98] Tomatoes can be preserved by canning, freezing, drying, or cooking down to a paste or puree. [99]
Early Girl can tolerate temperatures as low as 40 °F (4 °C) [1] and is well-suited to hot, dry climates. [2] Early girl is reliable and prolific. The ripe fruit is extremely standard for a tomato, about the size and shape of a tennis ball and weighing 4 to 8 ounces (110 to 230 g). The tomatoes have a bright color and good flavor.
The autoignition temperature or self-ignition temperature, often called spontaneous ignition temperature or minimum ignition temperature (or shortly ignition temperature) and formerly also known as kindling point, of a substance is the lowest temperature at which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark.
