abstract = "Two groups of market samples were collected: four samples of whey produced in
small scale facilities, and four samples produced in large scale dairy factories. The
additional two groups: acid (a) and sweet whey(s) were collected in laboratory
from cheeses produced from differently heated goat milk (A—65°C/30 min,
B—80°C/5 min and C—90°C/5 min). Gross composition (dry matter content, fat
content, protein content), pH, protein, mineral composition and microbial counts
were determined. Obtained results for laboratory and market whey samples
were analyzed by two-way and one-way ANOVA, respectively. Visualization
of quantitative relationships within market and laboratory whey samples has
been done by principal component analysis (PCA). Comparison of the protein
composition of market samples with those from the laboratory suggested that the
majority of goat whey from the market originated from milk heated between 65
and 80°C. While heat treatment of milk affected protein composition, coagulation
type determined mineral composition of whey. The amount of Ca content was
almost four times higher, while the amount of Zn is more than 15 times higher
in acid than in sweet goat whey. The lack of influence of heat treatment on the
Ca and Mg content in whey has been detected. Such behavior is the opposite of
cow milk behavior, in which with the subsequent increase in heating temperature,
the amount of soluble Ca and Mg decreases. For all analyzed samples, dry matter
content was in agreement with the legally required minimum level (5.5%). Although
legal requirements for safety and quality of small scale dairy products are more
flexible than that of the large counterparts, there was not a single characteristic
that differed significantly between small scale and large scale market goat whey.",
