ABSTRACT

Cheeses with 60% reduced fat were prepared with three fat mimetics and viscoelasticity was studied. Storage and loss moduli of low-fat cheeses made with a carbohydrate-based fat mimetic were greater (p < 0.05) than those of low-fat cheeses made with two protein-based fat mimetics or low-fat control cheese, but smaller (p < 0.05) than the storage and loss moduli of full-fat cheese. A six-element Kelvin model properly predicted the creep compliance for the full-fat cheese and the low-fat cheeses made with or without fat mimetics. Low-fat cheese made with a carbohydrate-based fat mimetic had a network structure more similar to full-fat cheese than the low-fat control or samples made with protein-based fat mimetics.
