Cottage cheese is a fermented, slightly acidic, unripened milk product
consisting of curd granules and a cream dressing. The cheese curd
is made from low-pasteurised skim milk and acidified with a classical
mesophilic starter culture containing Lactococcus lactis subsp. lactis
and L. lactis subsp. cremoris (O-culture). The added cream dressing
may be fresh or cultured using a diacetyl producing culture (L. lactis
subsp. lactis biovar. diacetylactis). Both product types are widely available
on the Scandinavian market. Cottage cheese has high moisture
content (N80%), low salt content (1.0–1.2%) and pH below 5.5.
