The aim of the study was to obtain and describe crispy snacks purely made of cheese (also referred to as ‘pure’ cheese snacks) using microwave vacuum drying technology. An acid‐set ripened cheese (Harzer cheese) was tested as the raw material. Cutting, hot air drying and microwave vacuum drying were applied in the technology process. This paper investigates the impact of these processes on the physical properties of the puffs; it also includes sensory evaluation of the resulting product. The cheese pieces expanded by ca. 1000% of their original size with a sharp decrease in the bulk density of the puffed samples. Water activity, hardness and brittleness of the cheese puffs were 0.35, 1511.17 g and 3.20 mm, respectively. The CIE LAB coordinates (in spin position), L*, a* and b*, were 82.81, 1.51 and 20.54, respectively. This paper shows that a new form of dairy product can be produced using microwave technology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
