摘要:

利用从传统发酵乳制品分离获得的乳酸乳球菌乳脂亚种KLDS4.0326和乳酸乳球菌乳酸亚种KLDS4.0424生产切达干酪,并分析干酪成熟期间的蛋白水解情况、微观结构变化、质构参数变化以及风味物质分布。结果表明:随着成熟时间的延长,酪蛋白含量降低,并分解产生新的小肽;硬度和凝聚性随着成熟时间的延长而降低,而黏着性、弹性、咀嚼性则增大;干酪横断面的孔径逐渐变小,网状结构逐渐紧密,形成比较致密光滑的质地。实验组干酪共检测出59种风味物质,其中挥发性酸和羰基化合物是干酪特征风味的主要来源。

Abstract:

Lactococcus lactis KLDS4.0326 and KLDS4.0424 isolated from traditionally fermented dairy products were
used to produce Cheddar cheese, and the proteolysis, microstructural change, texture parameter variation and flavor substance
distribution were analyzed during cheese ripening. Our results showed a decrease in casein content and formation of
some new small peptides as well as hardness and cohesion, but an increase in adhesion, elasticity and chewiness as well as
maturation time. More compact cross-section of cheese was observed, thus forming a relatively dense and smooth texture.
Fifty-nine kinds of flavor compounds were detected in the cheeses, among which the volatile acids and carbonyl compounds
were the major source of the characteristic cheese flavor.

Key words: Lactococcus lactis, cheese, texture, flavor compounds
