“…Gel-like materials containing emulsified fat include several manufactured food products, for example, yoghurt, some cheeses, thick sauces, and meat products (frankfurters and spreadable pastes). The physical result of incorporating emulsified fat droplets into gel matrices is either a reinforcement of the structure, if the gel network attaches to the interfacial layer of oil droplets, or a weaker structure if this interaction occurs to a limited extent (Aguilera and Kessler, 1989; Dickinson, 2012; Mession et al., 2013). Although emulsions are generally formed by mechanical means, a simple and energy saving procedure to generate oil droplets is to use ultrasound energy (Awad et al., 2012; Ching et al., 2015).…”
