Bases científicas do servir champanhe


ResearchBlogging.org
Chegada de 2011, um espumante para brindar é quase obrigatório. Você se preocupa em como servi-lo?
A depender da idade, lembrará que antes servia-se o espumante em taças de boca bem larga - a famosa taça para champanhe. Somente mais tarde, passaram a dominar as taças flauta. Porque houve a mudança? A idéia é preservar as bolhas, ou seja não perder o CO2 na mistura.
Há embasamento científico na mudança do formato da taça? e para a maneira de servir: taça em pé ou taça inclinada? e a temperatura?
Claro que há. O que de Liger-Belair da Universidade de Reims (da França, comme il faut) tem feito muitas contribuições científicas no tema.
O champanhe contém cerca de 12 gramas de CO2 dissolvido por litro de bebida (9 gramas na garrafa de 750 ml tradicional). Quando se abre a garrafa se inicia a perda deste gás, pois a concentração de CO2 na atmosfera é muito mais baixa que no champanhe. 
Quanto à  temperatura, foram testadas as condições de perda de CO2 em temperaturas de 4oC, 12oC e 20oC em taças tipo flauta. Quanto menor a temperatura, menor a perda da concentração de CO2 o que comprova que a temperatura prolonga a efervescência da champanhe. A viscosidade do líquido, a qual depende da temperatura, também é importante neste processo.
Sobre a inclinação da taça? Ao servir verticalmente, promove-se maior turbulência e maior perda de CO2, simples assim, mas tudo corretamente e precisamente medido.
“In this review, the latest results about the chemical physics behind the bubbling properties of Champagne and sparkling wines are collected and fully illustrated. The chemistry of carbon dioxide molecules dissolved into the liquid matrix (section 2) is presented, as are the three main steps of a fleeting bubble's life, that is, the bubble nucleation on tiny particles stuck on the glass wall (section 3), the bubble ascent and growth through the liquid matrix (section 4), and the bursting of bubbles at the liquid surface (section 5), which constitutes the most intriguing, functional, and visually appealing step.”
Que saber mais detalhes? O mesmo grupo tem publicado bastante sobre o tema (as referências estão no final do post).
Se você não está disposto a muita leitura, aí vão as recomendações:
  • taça flauta;
  • manter a taça inclinada (como os bebedores de cerveja que não gostam de colarinho);
  • servir a bebida a 4oC.
Não esqueça que no ano passado já comentamos sobre os efeitos benéficos da champagne sobre a saúde (aqui).

Evolution of Infectious Diseases (R01)

The National Institutes of Health (NIH), a part of the U.S. Department of Health and Human Services, is the primary Federal agency for conducting and supporting medical research. Helping to lead the way toward important medical discoveries that improve people's health and save lives, NIH scientists investigate ways to prevent disease as well as the causes, treatments, and even cures for common and rare diseases. Composed of 27 Institutes and Centers, ICs, the NIH provides leadership and financial support to researchers in every state and throughout the world.

This Funding Opportunity Announcement (FOA) solicits Research Project Grant (R01) grant mechanism from institutions/organizations that propose to study the evolutionary principles that underlie the emergence, spread, and containment of infectious disease. An explicit goal of the FOA is to stimulate interdisciplinary research between (a) quantitative and computational sciences and (b) experimental, clinical, or field studies. Areas of particular interest include the evolution of pathogens, evolutionary dynamics of host-pathogen systems, and the consequences of intervention strategies. The focus of this program is limited to discovery of fundamental biological principles rather than to detailed knowledge or treatment of specific diseases. Research applications submitted in response to this announcement may propose to study:

 

1.         Human or non-human pathogens;

2.         In vivo or in vitro systems;

3.         Microbial, animal, or plant models;

4.         Simulated or computational models.

5.          

Data Limite: New Applications Submission Date(s): Feb 5, Jun 5, and Oct 5. AIDS and AIDS-Related Applications: Jan 7, May 7, and Sept 7.Expiration Date: January 8, 2011.

Institute for Protein Research's International Collaborative Research

The Institute for Protein Research (IPR) was thus founded formally on 1958 as a part of Osaka University. Since then, IPR has developed significantly in terms of its scientific activity and infrastructures. Now, the IPR comprises four divisions with twelve laboratories and an attached research center with six laboratories, serving as a joint-use facility for the scientists working in the fields of protein and related sciences.

The Institute invites applications for international collaborative research. The research should be conducted in the form of a collaboration including at least one of the Principal Investigators (PIs) at IPR, or it should use particular experimental facilities of IPR, including solution- and solid-state-NMR spectrometers with ultra-high magnetic fields, and a synchrotron beam line for biological macromolecular assemblies at SPring-8.
