摘要
利用超高压处理制作好的低脂半硬质Bod Ljong干酪,研究超高压处理对干酪质构和风味的影响。超高压处理能增加干酪中水分,降低干酪硬度。通过SPME-GC-MS方法对干酪中的风味化合物进行分析,酯类化合物最多,但是对风味的改善作用有限。经过超高压处理后的低脂干酪入口后细腻爽滑,有轻微的颗粒感。
The effect of cycled high pressure treatment of milk on the yield, texture and flavour characteristic of low fat semi-hard Bod Ljong cheese were investigated. Bod Ljong cheeses were made from pasteurized, or pressure treated low fat milk according to traditional methods. High pressure treatment increased the moisture content of the cheese and reduced the hardness. Then the volatile flavor compounds were analyzed by solid-phase micro-extraction-gas chromatograph mass spectrometer（SPME-GC/MS）. Among the flavor compounds, ester compounds were the most abundant, however, the improvement in cheese flavor was limited. For the sensory evaluation, the low-fat cheeses are smooth and slightly granular.
