Emulsion gel fat as well as preparation method and application thereof

The invention discloses emulsion gel fat and a preparation method and application thereof, the emulsion gel fat is composed of a hydrogel phase and an oil gel phase, the oil gel phase is composed of an oil gel agent, an emulsifier and edible vegetable oil, and the hydrogel phase is composed of a hydrogel agent and water. According to the invention, an oil gel and a hydrogel are adopted to carry out structured treatment on an oil phase and a water phase to prepare a double-gel emulsion, and the double-gel emulsion can be used as a fat-like body to present good viscoelasticity and can completely or partially replace traditional plastic fat; the prepared fat-like product has excellent extrusion and shear resistance and self-supporting performance, can stably produce wires in the 3D printing process, quickly recover rigidity, is good in supporting performance, is suitable for printing of various complex models, has the nutritional characteristics of zero trans-fatty acid, low saturated fatty acid and low fat, and
