Abstract
AbstractThe beneficial role of dietary fibre in human nutrition has lead to a growing demand for incorporation of novel fibres, particularly barley β‐glucans, into foods. Barley β‐glucans are regarded as dietary fibre ingredients that are partially soluble in water. The aim of the present work was to investigate the possibility of using barley β‐glucan in milk systems in relation to the coagulation properties of milk containing β‐glucan, and to the rheology, texture and microstructure of fresh curds. The rate of coagulation and optimum coagulum cutting time were evaluated using rheological measurements. Results show that coagulation/gelation time of the milk can be reduced significantly with the incorporation of β‐glucan; curd yield increased and the viscoelastic properties of the curd were altered with β‐glucan additions. The relationships between curd rheological behaviour and its microstructure are discussed in relation to use of novel hydrocolloids in dairy processing. The results suggest that barley β‐glucan has the potential to be used as a fat replacer in low‐fat dairy systems. Copyright © 2004 Society of Chemical Industry
