The objective of the study was to compare the sensory profile of Cheddar cheese prepared from cow and buffalo milk using indigenous and commercial cultures. Commercially available and locally isolated, indigenous starter cultures were used to prepare cow and buffalo milk Cheddar cheese. The cheese was ripened at 4 and 12°C and analyzed for descriptive sensory profile by a panel of 10 assessors after 60 and 120 d of ripening. On evaluation, the mean scores for odor, flavor, and texture attributes obtained for buffalo milk cheese were significantly higher than those obtained for cow milk cheese. For most of the traits, cheese samples prepared from indigenous cultures and ripened at higher temperature received higher descriptive scores compared with those of commercial cultures and ripened at lower degrees. Milk sources highly significantly affected the "creamy" and "sour" traits of odor; the "creamy," "smoky," and "soapy" flavors; and all the texture attributes except "maturity." Starter cultures considerably influenced the production of "acidic," "bitter," "sweet," and "sour" characteristics. The use of elevated ripening temperature showed noticeable effect on all the characteristics except the "creamy" odor and flavor. Principal component analysis and hierarchical cluster analysis also showed that milk sources, starter cultures, and ripening temperatures significantly influenced the sensory characteristics.
本研究旨在比较使用本土和商业培养物制作的来自奶牛和水牛乳的切达奶酪的感官特性。使用市售和本地分离的本土起始培养物来制备奶牛和水牛乳切达奶酪。将奶酪在 4°C 和 12°C 下成熟,并在成熟 60 和 120 天后由 10 名评估员对其进行描述性感官特性分析。在评估中,水牛乳奶酪的气味、风味和质地属性的平均得分明显高于牛乳奶酪。对于大多数特征,与商业培养物在较低温度下成熟的奶酪样品相比,在较高温度下使用本土培养物制备和成熟的奶酪样品获得了更高的描述性得分。奶源高度显著影响气味的“奶油味”和“酸味”特征;风味的“奶油味”、“烟熏味”和“肥皂味”;以及除“成熟度”外的所有质地属性。起始培养物对“酸性”、“苦味”、“甜味”和“酸味”特征的产生有很大影响。提高成熟温度的使用对除“奶油味”气味和风味外的所有特征都有明显的影响。主成分分析和层次聚类分析也表明,奶源、起始培养物和成熟温度显著影响感官特性。
