microbiology of cheese production

Others are allowed by the cheesemaker to develop bacterial surface growths which give characteristic colours and appearances, e.g. This ensures a product of good quality that will keep. Some cheeses may be deliberately left to ferment from naturally airborne spores and bacteria; this approach generally leads to a less consistent product but one that is valuable in a niche market.

In Ireland, some cheeses ranged from a dry and hard cheese (mullahawn) to a semi-liquid cheese (millsén).[5]. "With cheese production, you are relying heavily on good bacteria ," says D'Amico. By taking the cheese through a series of maturation stages where temperature and relative humidity are carefully controlled, the cheesemaker allows the surface mould to grow and the mould-ripening of the cheese by fungi to occur. Bacteria which produce only lactic acid during fermentation are homofermentative; those that also produce lactic acid and other compounds such as carbon dioxide, alcohol, aldehydes and ketones are heterofermentative. The grading process is one of sampling by sight, smell, taste and texture. Since many monastic establishments and abbeys owned their share of milk animals at the time, it was commonplace for the cheeses they produced to bear a cross in the middle. Before the age of pasteurization, cheesemakers knew that certain cheeses can cause constipation or kidney stones, so they advised their customers to supplement these side effects by eating in moderation along with other foods and consuming walnuts, almonds, or horseradish.[6][7]. Rennet is a type of enzyme that is produced in a mammal's stomach that causes the curd, or solid portion of the cheese, to form. Vermont: Chelsea Green Publishing. Meanwhile, in the cheese room, Howard is ramping back the amount of commercial starter he uses, stretching the make out into a long and leisurely process that allows the milk’s native bacteria to grow steadily alongside the added cultures and play an increasingly-important role in flavour production. Moreover, goats can breed any time of the year as opposed to sheep, who also produce milk, but mating season only came around during fall and winter.

The cheesemaker must, therefore, remove most of the water (whey) from the cheese milk, and hence cheese curd, to make a partial dehydration of the curd. The cheese curds are then removed from the hoops to be brined by immersion in a saturated salt solution. Less moisture meant that the cheese would be more firm.

Vacuum packing removes oxygen and prevents mould (fungal) growth during maturation, which depending on the wanted final product may be a desirable characteristic or not. 38.1, Table 38.1). The whey proteins, other major milk proteins, and lactose are all removed in the cheese whey. The milk is traditionally from a cow, goat, sheep or buffalo, although worldwide cow's milk is most commonly used and, in theory, cheese could be made from the milk of any mammal. The curd is cut using long, blunt knives and 'blocked' (stacked, cut and turned) by the cheesemaker to promote the release of cheese whey in a process known as 'cheddaring'. Cheesemaking (or caseiculture) is the craft of making cheese. After a period of aging, the cheese is ready to be eaten, hopefully free of pathogenic bacteria.

Main microorganisms involved in cheese making 1- Lactic acid bacteria These bacteria in the milk may be wild, as is the case with unpasteurised milk, added from a culture, frozen or freeze dried concentrate of starter bacteria.
