Por que uma batedeira gelada ajuda ao fazer chantilly? Tem algum efeito sobre quanto tempo o creme fica batido?

Basicamente, o creme chicoteia melhor quando está frio. Se o creme fosse armazenado quente, o conselho seria esfriar o creme. Como já está frio, o conselho é esfriar o equipamento (pois o equipamento aquecido aumentará a temperatura do creme).

Ciência leve: a temperatura afeta o tamanho das bolhas que se formam, como a gordura se apega a si mesma, o tempo de chicote e o excesso (estrutura da célula aérea / volume da fase aérea). Em outras palavras, quão leve e fofo ela vai ficar e por quanto tempo é provável que continue assim.

Atenção, ciência pesada de Influência da temperatura de chicoteamento nas propriedades de chicoteamento e nas características reológicas de Chantilly :

The effects of whipping temperature (5 to 15°C) on the whipping (whipping time and overrun) and rheological properties of whipped cream were studied. Fat globule aggregation (aggregation ratio of fat globules and serum viscosity) and air bubble factors (overrun, diameter, and surface area) were measured to investigate the mechanism of whipping. Whipping time, overrun, and bubble diameters decreased with increasing temperature, with the exception of bubble size at 15°C. The aggregation ratio of fat globules tended to increase with increasing temperature. Changes in hardness and bubble size during storage were relatively small at higher temperatures (12.5 and 15°C). Changes in overrun during storage were relatively small in the middle temperature range (7.5 to 12.5°C). From the results, the temperature range of 7.5 to 12.5°C is recommended for making whipped creams with a good texture, and a specific temperature should be decided when taking into account the preferred overrun. The correlation between the whipped cream strain hardness and serum viscosity was high (R2=0.906) and persisted throughout the temperature range tested (5 to 15°C). A similar result was obtained at a different whipping speed (140rpm). The multiple regression analysis in the range of 5 to 12.5°C indicated a high correlation (R2=0.946) in which a dependent variable was the storage modulus of whipped cream and independent variables were bubble surface area and serum viscosity. Therefore, fat aggregation and air bubble properties are important factors in the development of cream hardness. The results of this study suggest that whipping temperature influences fat globule aggregation and the properties of air bubbles in whipped cream, which alters its rheological properties.
