摘要
奶泡品质包含香味、光泽、口感、滋味等,通过研究6款不同品牌意式半自动咖啡机的蒸汽性能对所制备的奶泡品质的影响,明晰蒸汽性能与奶泡品质之间的内在关系.研究发现,意式半自动咖啡机的蒸汽性能显著影响奶泡品质,当其发泡时间短、蒸汽含水率低、精确度低,所制备的奶泡品质处于较高水平.6款意式半自动咖啡机中,国外品牌F蒸汽性能最优,发泡时间57 s、蒸汽含水率9.50％、精确度1.40,所制备的奶泡品质最佳,稳定性87.08％、绵密度46 s,且在主观评价上得分最高.此外,国内品牌D与国外品牌F在蒸汽性能以及奶泡品质上无显著差异.
Abstract
The quality of milk froth includes aroma,luster,flavor,taste,etc.In order to clarify the relationship between steam performance and the quality of milk froth,the effects of steam performance on the quality of milk froth were investigated by comparing 6 different brands of expresso coffee machines.It was found that the steam performance of espresso coffee machines significantly affected the quality of milk froth.When the foaming time was short,the water content of steam was low,and the precision was low,the quality of milk froth was at a high level.Among 6 espresso coffee machines,the steam performance of foreign brand F was the best.In foreign brand F,the foaming time is 57 s,the water content of steam is 9.50％,and the precision is 1.40.Besides,the milk froth made by foreign brand F had the best quality with 87.08％stability,46 s milk density,and the highest score in subjective evaluation.In addition,there was no significant difference between domestic brand D and foreign brand F in terms of steam performance and milk froth quality.
