Mechanism and control of the eye formation in cheese


Abstract

The production of Swiss-type cheeses with a typical number, size, and distribution of eyes is a difficult task, especially when bactofuged or microfiltrated milk is utilised. In this study, the potential of microparticles (plant origin) to influence eye formation in cheese, was assessed. Eight experimental Emmental cheeses were produced with one replicate from microfiltrated milk with addition of 0.0625–4.000 mg of powdered hay to the milk (90 L) and ripened for 130 days. Eye formation was quantified by means of X-ray computed tomography (between 30 and 130 days). The contents of fat, water, citric acid, lactic acid, and volatile carboxylic acids were determined at 130 days. The results demonstrate that microparticles of plant origin act as eye nuclei that control the number (P < 0.001) and size of the eyes in cheese in a dose-dependent manner. The findings also provide new insights into the formation of eye defects.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
