On the Chemical Pathways Influencing the Effective Global Warming Potential of Commercial Hydrofluoroolefin Gases.

The enforcement of a global hydrofluorocarbon (HFC) refrigerant phase down led to the introduction of hydrofluoroolefins (HFOs) as a low Global Warming Potential (GWP) substitute, given their low atmospheric lifetime. However, to this date it is not fully clear the long-term atmospheric fate of HFOs primary degradation products: trifluoro acetaldehyde (TFE), trifluoro acetyl fluoride (TFF), and trifluoroacetic acid (TFA). It particularly concerns the possibility of forming HFC-23, a potent global warming agent.

Storage stability of anthocyanins in freeze-dried elderberry pulp using low proportions of encapsulating agents.

Berry fruits are well recognized for health-promoting constituents due to their properties of free radical scavengers which confer antioxidant activity against cellular oxidation reactions. Elderberry fruit contains one of the highest levels of anthocyanins. The objective of this work was to evaluate the storage stability of total monomeric anthocyanins, cyanidin-3-glucoside (one of two major anthocyanins in elderberry), and color parameters in freeze-dried elderberry encapsulated with a low proportion of different carriers (Maltodextrin, Capsul™, Promitor ™, and κ-carrageenan).
