The invention belongs to the technical field of food and discloses a compound emulsification thickener and soft ice cream pulp containing the compound emulsification thickener. The compound emulsification thickener is prepared from the following raw materials: 1.5-2.5 parts by weight of an emulsifier, 3-6 parts by weight of pectin, 0.4-1.2 parts by weight of alginic acid derivatives and 4.6-7.2 parts by weight of one or more of gelatin, xanthan gum, locust bean gum and sodium carboxymethyl cellulose. By virtue of synergistic effects of all the components, the stability of fermented type soft ice cream pulp in a normal-temperature storage process can be improved. Furthermore, when the compound emulsification thickener provided by the invention is used for preparing the fermented type soft ice cream pulp, after a freezing machine is used for performing stirring, the product is delicate and smooth in taste, free of fat crystallization and free of ice crystal feeling.
