Abstract
This study investigated the impact of seasonality (lactation stage), milk storage time and somatic cell count (SCC) on the chemical ripening and sensory characteristics of hard goat milk cheese ripened for 12–18 months. Milk was collected from four farms at four stages: indoor feeding (A), mountain pasture release (B), high summer pasture (C), and lowland pasture during oestrus (D). Cheeses were produced the following- and three days after delivery. Quantitative Descriptive Analysis (QDA) revealed significant seasonal differences in sensory attributes. Cheeses from season C and D exhibited more ‘sweet taste’ and ‘caramel flavour’, while those from season A had more ‘oxidized odour’ and ‘acidic taste’. Season C and D cheeses had higher levels of total free amino acids (FAA), and a stickier, more cohesive texture compared to the drier, grittier texture of season A cheeses. The results indicate that season and bulk milk storage time have a greater effect on cheese sensory and chemical properties than SCC, although SCC did have an impact. Developing production protocols that consider seasonal variation (lactation stage) and SCC, is essential to optimise cheese quality standardisation, benefiting small-scale artisanal and industrial goat cheese producers.
期刊介绍:
The International Dairy Journal publishes significant advancements in dairy science and technology in the form of research articles and critical reviews that are of relevance to the broader international dairy community. Within this scope, research on the science and technology of milk and dairy products and the nutritional and health aspects of dairy foods are included; the journal pays particular attention to applied research and its interface with the dairy industry.
The journal''s coverage includes the following, where directly applicable to dairy science and technology:
• Chemistry and physico-chemical properties of milk constituents
• Microbiology, food safety, enzymology, biotechnology
• Processing and engineering
• Emulsion science, food structure, and texture
• Raw material quality and effect on relevant products
• Flavour and off-flavour development
• Technological functionality and applications of dairy ingredients
• Sensory and consumer sciences
• Nutrition and substantiation of human health implications of milk components or dairy products
International Dairy Journal does not publish papers related to milk production, animal health and other aspects of on-farm milk production unless there is a clear relationship to dairy technology, human health or final product quality.
