About whey

cpc code 22130 covers the industry of whey production. Whey is a byproduct of the cheese-making process, and it is a valuable commodity in the food and beverage industry. As a rich source of protein, lactose, and other nutrients, whey has a wide range of applications, from sports nutrition to infant formula. The whey industry plays a crucial role in the broader dairy sector, contributing to the efficient utilization of dairy resources and supporting the overall profitability of the dairy supply chain.

Production process

The production of whey involves several key steps. First, the curds are separated from the liquid whey during the cheese-making process. The whey is then subjected to various processing techniques, such as filtration, evaporation, and drying, to concentrate the valuable components and remove excess water. Depending on the desired end-product, the whey may undergo further processing, such as ion exchange or membrane filtration, to isolate specific fractions like whey protein concentrate or whey protein isolate.

Production inputs

The main inputs required for the whey industry include raw milk, which is the primary source of whey, as well as specialized equipment and machinery for the processing and drying of whey. Additionally, the industry relies on energy sources, such as electricity and natural gas, to power the various processing steps. Transportation infrastructure is also a critical input, as whey must be efficiently transported from cheese-making facilities to whey processing plants.

Production outputs

The primary output of the whey industry is a range of whey-based products, including 22131 Whey, liquid or powdered, 22132 Whey protein concentrates, and 22133 Whey protein isolates. These products are widely used in the food and beverage industry, as well as in the production of sports nutrition supplements, infant formula, and other specialized products. The whey industry also generates byproducts, such as lactose, which can be further processed and utilized in various industries.
