“…(b) N2 has a lower aqueous solubility and thus reduced gas diffusion and disproportionation. The bubbles will be more stable (Carroll, 1979;Mitani et al, 2002;Bamforth, 2004a). (c) N2 produces a more "creamy" foam texture while CO 2 makes the texture "prickle" (Carroll, 1979).…”

“…Schopnost úniku CO 2 závisí na přítomnosti a koncentraci nukleačních center, jak o tom svědčí i pokusy s mísením (řezáním) piva (Brož a Košin, 2012) . Dosud není jednoznačně prokázaná povaha nukleačních center, neboť ani moderní optické metody nemohou spolehlivě rozlišit mezi pevnými nanočásticemi a stabilizovanými mikrobublinkami samotného plynu (Mitani a Joh, 2002) . Tzv .…”

“…The ability to liberate CO 2 depends on the presence and concentration of nucleation centers, as evidenced by experiments with blending beer (Brož and Košin, 2012) . It is not yet clear whether the nature of the nucleation centers are solid nanoparticles or stabilized gas microbubbles alone, although a modern optical methods are used (Mitani and Joh, 2002) . So called hydrofobins will normally be considered as stabilizers of the already formed microbubbles of gas, but their speculative ability to influence the bond between solid and gas cannot be excluded .…”

“…) S = the solubility of the gas (mol m -3 Pa -1 )  = the surface tension t = time (s) P = pressure  = the film thickness between bubbles This explains the enormous benefits that nitrogen gas (much less soluble than carbon dioxide) has for beer foam stability 10,14,28,104 , remembering that nitrogen adversely impacts the flavour of many beers 63 .…”
