ANSWER
Plant based hydrocolloids such as locust bean gum and guar gum are suitable for vegetarians and gluten free formulations. Hydrocolloids give structure and emulsifying properties to egg-free end products (Donnell, 2015). Apart from hydrocolloids, a vegan eggless cake system may include emulsifiers from plant origins such as mono- and diglycerides and polyglycerol. Emulsifiers provide the necessary aeration and gas bubble stability during the baking process (Rahmati & Tehrani, 2014).
