Because the vast majority of our customers and their consumers are looking for dairy products that are free from artificial hormones, we have decided to produce products that are made with milk from cows that have not been treated with artificial growth hormones (rBST). All fluid milk, creams and ice cream mixes manufactured by Cumberland Dairy, is from farmers who pledge not to use artificial growth hormones on their herds.
Since cows naturally produce BST, bovine somatotropin, dairy products cannot be tested for the artificial version rBST” (recombinant bovine somatotropin). Even though this drug has been tested and approved by the FDA for use in dairy cows, the farmers that supply milk to our facility have pledged not to use artificial growth hormones
Currently, all products produced at Cumberland Dairy are processed at ultra-pasteurized temperatures. Even though the products are packaged under high hygiene conditions, these fillers are not aseptic fillers and therefore the products we pack require refrigeration.
Ultra-pasteurization, the most widely used pasteurization process for milk in Europe and throughout the world, is a more recently developed process. The ultra-pasteurization process is often referred to as “Ultra High Temperature,” or UHT pasteurization. The UHT process heats the milk to 280° F for only two seconds, and eliminates a larger percentage of bacteria than HTST pasteurization. When coupled with sterile packaging, the ultra-pasteurization process creates an extended shelf life.
Once the product is processed, it can be packaged in two different ways depending on the customer need. Many companies, especially those in Europe package the product in “shelf-stable” or “aseptic” packaging. This packaging will allow the product to be shipped and store unrefrigerated for a shelf life of up to one year. At Cumberland Dairy, we utilize ESL (extended shelf life) packaging technology which looks very comparable to a traditional dairy package, but is filled in a sterile filling environment. While this package looks similar to others on the shelf, we can achieve a much longer shelf life under proper refrigerated temperatures due to the combination of the ultra-pasteurization and the ESL packaging. Depending on the product we are producing, it can carry a refrigerated shelf life of 60 to 90 days.
