    Acid whey is a valuable raw material obtained during acid-coagulated cheese and acid casein production. Nowadays whey processing techniques are well developed, however the utilization of acid whey, due to low pH, still remains a challenge especially for small dairy plants. The aim of the study was to design and evaluate the fermented beverages based on acid whey containing yogurt bacteria starter cultures. In order to enrich casein content and obtain product with quality characteristics similar to fermented milk drinks, whey was combined with milk, unsweetened condensed milk or skimmed milk powder. Moreover, the beverages were supplemented with prebiotics: inulin and oligofructose and whey protein concentrates. The evaluation of the beverages included acidity measurement and sensorial analysis. Moreover the conditions of whey pasteurization were evaluated. According to the results, the best raw materials and additives were selected. It was stated, that to obtain the product with good sensory characteristics, the addition of milk must amount minimum 50%. The results allowed to invent several kinds of fermented beverages with desirable properties. The most appropriate conditions of whey heat treatment was pasteurization at the temperature of 72°C for 10 minutes. The obtained results indicated that acid whey can be considered as a raw material for the production of fermented beverages with acceptable sensory quality. The practical impact of the work comes from the aspect, that it presents the new method of direct utilization of acid whey and it may be a new, attractive alternative for dairy industry.

    Whey is a by-product of dairy industry obtained during cheese and casein production. Despite the low dry matter content, whey is a valuable by-product in terms of functional and nutritional properties and it has high potential of application. In the past it was treated as a problematic waste, but nowadays due to increasing amount of whey production and better knowledge about its properties, the whey processing technology is dynamically developing. The aim of the review was a presentation of methods used in whey application and characterization of formulations obtained from whey. Furthermore the article presents the current trends of whey utilizing mainly in the production of food and also in other branches of industry.
