Answer:
cheese was made from milks with and without growth of psychrotrophic bacteria before pasteurization. Chemical and bacteriological evaluations were made on the milks and on whey and cheese from the milks. Sensory evaluation was also done on cheese samples. The percentage of nonprotein nitrogen and noncasein nitrogen increased over control milks when milk with psychrotrophic bacteria was held at 4.4 C for 7 days. Processing time was decreased and a firmer curd resulted when Cheddar cheese was made from milk cultured with psychrotrophic bacteria rather than control milk. Differences were minor for milkfat, moisture, nitrogen content, and pH between cheeses made from control and precultured milks. Sensory evaluation revealed little difference between cheeses from control and treated milks at 3 mo of ripening at 4.4 or 10 C. Unacceptable changes became evident at 6 mo, especially for cheeses ripened at 10 C.
It all starts with collecting milk from dairy farms. Once it’s brought to the cheese plant, the cheesemakers check the milk and take samples to make sure it passes quality and purity tests.
Once it passes, the milk goes through a filter and is then standardized – that is, they may add in more fat, cream or protein. This is important because cheesemakers need to start with the same base milk in order to make a consistent cheese. After the milk is standardized, it’s pasteurized. Pasteurization is necessary because raw milk can harbor dangerous bacteria, and pasteurization kills those bacteria.
At this point, good bacteria or “starter cultures” are added to the milk. The starter cultures ferment the lactose, milk’s natural sugar, into lactic acid. This process helps determine the cheese’s flavor and texture. Different types of cultures are used to create different types of cheese. For example, Swiss cheese uses one type of culture, while Brie and Blue use others. After the starter culture, a few other ingredients are added including rennet and, depending on the type of cheese, color -- which is why Cheddar is orange.
