Whey is a by-product of the cheese-making process, obtained after casein precipitation. It is the cloudy, yellowish liquid expelled from cheese curds during the cheese-making process. Whey is used to make whey cheeses such as ricotta, brunost, and whey butter, as well as many other products for human consumption. Whey is also used as an additive in processed foods and animal feed. However, due to the high biological oxygen demand (BOD) caused by its high lactose concentration, the disposal of whey can be environmentally problematic for the dairy industry.

What You'll Learn
Whey is a by-product of cheese-making
There are two types of whey: sweet whey and acid whey. Sweet whey is the byproduct of rennet-coagulated cheese, and acid whey (also called sour whey) is the byproduct of acid-coagulated cheese. The type of whey produced depends on the type of cheese being made. For example, soft cheeses like cottage cheese, mozzarella, and goat cheese produce acidic whey, while harder cheeses like cheddar and Swiss cheese produce sweet whey.
In the past, whey was considered a waste product and was often pumped into rivers and streams, leading to environmental concerns. Today, there is a high demand for industrial whey protein, and it is used in various products, including protein shakes and bars, and added to foods like breads and pastries to increase their protein content. It is also used to produce whey cheeses like ricotta, brunost, and whey butter.
Whey can be purchased as a powder and used as a protein supplement, added to smoothies, or used in cooking. It is also an additive in many processed foods and is used in animal feed. The production of whey cheese allows cheesemakers to use the remaining whey instead of discarding it.
Overall, whey is a valuable by-product of cheese-making with numerous uses in the food industry.

It is used in whey cheese, like ricotta
Whey is a by-product of the cheese-making process. It is the liquid that is expelled from cheese curds when making cheese. The curds are then drained and pressed into a mold to make cheese. Whey is one of the two main proteins in milk. The other protein, casein, mostly ends up in the cheese.
Whey has a variety of uses. It is often used as animal feed or as fertiliser. It is also used in cooking, as it can be added to dressings and marinades, or used to boil pasta or rice. It can also be drunk straight or added to cocktails. It is used in baking, as it can be used in place of water or milk in bread and pastries. It can also be used to soak grains to reduce cooking time.
Whey is also used to make whey cheese. Whey cheese is made from the whey that remains after making cheese. Examples of whey cheese include ricotta, mizithra, and brunost. Ricotta is made by coagulating the albumin in the whey with heat and possibly acid. Brunost is made by boiling down the whey to concentrate the sugar. Whey cheese has a low lactose content and a white-to-yellowish colour.
Ricotta is traditionally made from the whey that remains after making another cheese. Italian ricotta is usually made from sheep's milk whey, while American ricotta is usually made from cow's milk whey.

It is a popular additive in processed foods
Whey is a byproduct of the cheesemaking process. It is the liquid that is expelled from cheese curds when making cheese. In the past, whey was considered a waste product and was often pumped into rivers and streams. However, it is now recognised as a valuable source of protein and is used in a variety of applications.
Whey is a popular additive in processed foods due to its functional and nutritional properties. It is used to improve the nutritional profile of products and can act as a dough conditioner. Whey is added to a variety of processed foods, including breads, crackers, pastries, and other baked goods. It can also be used as a substitute for skimmed milk in recipes. Whey is also used in the production of animal feed, providing a protein source for livestock.
The demand for whey protein has increased significantly, and it is now a primary product for some large-scale cheesemakers. Whey is also marketed as a standalone product in the form of protein supplements and shakes. It can be purchased in powdered form, both flavoured and plain, from health food stores, grocery stores, and gyms. Whey protein supplements are popular among health-conscious individuals and athletes due to their high protein content and perceived health benefits.
In addition to its use in processed foods and supplements, whey has a variety of other applications. It can be used in cooking, adding depth of flavour to dishes such as pasta, vegetables, and soups. It can also be used as a fertiliser for soil, although it must be diluted to prevent damage to plant roots. Whey has also been explored for its potential use in the pharmaceutical industry and in biotechnological processes.
Overall, whey is a versatile byproduct that has found a variety of uses beyond the simple disposal that was common in the past. Its functional and nutritional properties make it a valuable ingredient in the food industry, especially in the production of processed foods and protein supplements.

It is used in animal feed
Whey is a highly nutritious by-product of the cheese industry. It is the liquid expelled from cheese curds during the cheese-making process. In the past, whey was considered a waste product and was pumped into rivers and streams. However, it is now used in a variety of ways, including animal feed.
Whey can be used to feed a variety of animals, including poultry, pigs, rats, ruminants, and calves. It is particularly useful for young animals and fattening pigs. When fed to animals, whey can increase weight gain, feed efficiency, protein digestibility, and fat digestibility, as well as mineral absorption and retention. For example, adding whey to grass and legume silages improves the quality and digestibility of the silage.
Whey can be fed to animals in a variety of forms, including liquid whey and dried whey. Liquid whey was traditionally used for animal feed, but this practice has been superseded by drying for animal feed due to transport and storage concerns. Dried whey is easier to handle and has a longer shelf life than liquid whey.
The use of whey in animal feed has some potential drawbacks. For example, sour whey is less palatable to animals than sweet whey, and it can be difficult to ensure that the whey is free of pathogenic organisms. Additionally, if animals are given large amounts of lactose before their microbial population has adjusted, it can cause digestive disorders such as diarrhea or bloat.
Overall, whey is a valuable by-product of the cheese industry that can be utilized in animal feed to provide nutritional benefits to a variety of animals. However, it is important to carefully manage the use of whey in animal feed to avoid potential health and safety concerns.

It is sold as a protein supplement
Whey is a byproduct of cheesemaking. It is the liquid that is expelled from cheese curds when making cheese. This liquid contains lactose, vitamins, protein, and minerals, along with traces of fat.
Whey is used to produce whey cheeses such as ricotta, brunost, and whey butter, as well as many other products for human consumption. Whey proteins consist primarily of α-lactalbumin and β-lactoglobulin. Sweet whey, a byproduct of rennet-coagulated cheese, also contains glycomacropeptide (GMP).
Historically, whey was considered a waste product and was pumped into rivers and streams. Since whey contains protein, this practice was eventually prohibited as it led to the growth of large concentrations of algae, which were deemed hazardous to the ecosystem.
Today, whey is sold as a protein supplement in the form of whey protein powder. It is available in health food and grocery stores, online, in drugstores, and at gyms. Whey protein powder is typically flavoured, with options such as vanilla, chocolate, coffee, banana, and berry. It can be mixed with water, milk, or other beverages and is used as a post-workout drink to support muscle recovery and health. Whey protein powder is also used in smoothies and other blended drinks, pancakes, homemade energy bars, soups, stews, dressings, and marinades.
Whey protein powder is a fast-digesting protein, with Whey Concentrate, Whey Isolate, and Whey Hydro Isolate as the three types of fast-digesting proteins. Whey Concentrate is the cheapest option and typically a mass gainer with lots of carbs, while Whey Isolate is more expensive and can be digested within 2 hours. Whey Hydro Isolate is the most expensive option, the purest form of whey, and can be digested within an hour, making it ideal for post-workout drinks.
