In the United States, HFCS is among the sweeteners that have mostly replaced sucrose (table sugar) in the food industry. [7] [8] Factors contributing to the increased use of HFCS in food manufacturing include production quotas of domestic sugar, import tariffs on foreign sugar, and subsidies of U.S. corn, raising the price of sucrose and reducing that of HFCS, creating a manufacturing-cost ...
HFCs replaced older chlorofluorocarbons such as R-12 and hydrochlorofluorocarbons such as R-21. [2] HFCs are also used in insulating foams, aerosol propellants, as solvents and for fire protection. They may not harm the ozone layer as much as the compounds they replace, but they still contribute to global warming --- with some like ...
If released, HFCs stay in the atmosphere for decades and both PFCs and SF 6 can stay in the atmosphere for millennia. The total atmospheric concentration of F-gases, CFCs, and HCFCs has grown rapidly since the mid-twentieth century; a time which marks the start of their production and use at industrial scale.
Glucose syrup was the primary corn sweetener in the United States prior to the expanded use of high fructose corn syrup production in 1964. [14] HFCS is a variant in which other enzymes are used to convert some of the glucose into fructose. [15] The resulting syrup is sweeter and more soluble. [citation needed]
Some drinks will include added sugars like cane sugar, glucose, fructose, or high fructose corn syrup, while others use low or no-calorie natural sweeteners such as stevia, monk fruit, or allulose ...
As a result of CFCs contributing to ozone depletion in the upper atmosphere, the manufacture of such compounds has been phased out under the Montreal Protocol, and they are being replaced with other products such as hydrofluorocarbons (HFCs) and hydrofluoroolefins (HFOs) [1] including R-410A, R-134a and R-1234yf.

Compared to HCFCs and HFCs, HFOs have shorter tropospheric lifetimes due to the reactivity of the C=C bond with hydroxyl radicals and chlorine radicals. [1] This quick reactivity prevents them from reaching the stratosphere and participating in the depletion of good ozone, leading to strong interest in the development and characterization of ...
