The optimal day temperature range for cannabis is 24 to 30 °C (75 to 86 °F). [12] Temperatures above 31 °C (88 °F) and below 15.5 °C (60 °F) seem to decrease THC potency and slow growth. At 13 °C (55 °F) the plant undergoes a mild shock, though some strains withstand frost temporarily.
CBD heated to 175, [13] or 250–300 °C may partially be converted into THC. [14] Even at room temperature, trace amounts of THC can be formed as a contaminant in CBD stored for long periods in the presence of moisture and carbon dioxide in the air, with storage under inert gas required to maintain analytically pure CBD.
Levitz and Diamond (1991) suggest baking cannabis in home ovens at 150 °C [302 °F], for five minutes before smoking. Oven treatment killed conidia of A. fumigatus, A. flavus and A. niger, and did not lower THC levels. [103] Cannabis contaminated with Salmonella muenchen was correlated with dozens of cases of salmonellosis in 1981. [106]
For example, a cool oven has temperature set to 200 °F (93 °C), and a slow oven has a temperature range from 300–325 °F (149–163 °C). A moderate oven has a range of 350–375 °F (177–191 °C), and a hot oven has temperature set to 400–450 °F (204–232 °C).
These barns have flues which run from externally fed fire boxes, heat-curing the tobacco without exposing it to smoke, slowly raising the temperature over the course of the curing. In the 1960s conversion to gas fueled systems such as the Gastobac Burner System® [ 5 ] was common.
High-temperature fires see the flavor molecules broken down further into unpleasant or flavorless compounds. The optimal conditions for smoke flavor are low, smoldering temperatures between 300 and 400 °C (570 and 750 °F). This is the temperature of the burning wood itself, not of the smoking environment, which uses much lower temperatures.
Curing can be traced back to antiquity, and was the primary method of preserving meat and fish until the late 19th century. Dehydration was the earliest form of food curing. [1] Many curing processes also involve smoking, spicing, cooking, or the addition of combinations of sugar, nitrate, and nitrite. [1] Slices of beef in a can
After the soak segment, the profile enters the ramp-to-peak segment of the profile, which is a given temperature range and time exceeding the melting temperature of the alloy. Successful profiles range in temperature up to 30 °C higher than liquidus , which is approximately 183 °C for eutectic and approximately 217 °C for lead-free.
