Most foods are dehydrated at 130 °F (54 °C), although meats being made into jerky should be dehydrated at a higher temperature of 155 °F (68 °C)—or preheated to that temperature—to guard against pathogens that may already be in the meat.
Food drying is a method of food preservation in which food is dried (dehydrated or desiccated). Drying inhibits the growth of bacteria , yeasts , and mold through the removal of water . Dehydration has been used widely for this purpose since ancient times; the earliest known practice is 12,000 B.C. by inhabitants of the modern Asian and Middle ...
Because of this, dry-aged beef is seldom available outside of steak restaurants and upscale butcher shops or groceries. The key effect of dry aging is the concentration and saturation of the natural flavour, as well as the tenderization of the meat texture. The process changes beef by two means. Firstly, moisture is evaporated from the muscle.
Since jerky is heat-dried, the process is much faster than for making biltong. The meat used in biltong is often much thicker due to the faster drying time in dry air conditions; typically, biltong meat is cut in strips around 25 millimetres (0.98 in) wide, but can be thicker. Jerky is normally very thin meat.
A typical 30 g portion of fresh jerky contains 10–15 g of protein, 1 g of fat, and 0–3 g of carbohydrates, although some beef jerky can have a protein content above 65%. [10] Since traditional jerky recipes use a basic salt cure, sodium can be a concern for some people.

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.
For dry-aged beef, the meat is hung in a room kept between 33–37 degrees Fahrenheit (1–3 degrees Celsius), with relative humidity of around 85%. If the room is too hot, the meat will spoil, and if it is too cold, the meat freezes and dry aging stops. Good ventilation prevents bacteria from developing on the meat. The meat is checked on ...
