Summary: | The present invention relates to a preparation method of a W1/O/W2 fat substitute based on algal polysaccharides. W1 represents a first aqueous phase; W2 represents a second aqueous phase; O represents an oil phase; vegetable oil dissolved with a lipophilic emulsifier is used as the oil phase; an inorganic salt solution is used as the first aqueous phase; the oil phase and the first aqueous phaseare first emulsified to obtain a main emulsion; an inorganic salt solution dissolved with carrageenan is used as the second aqueous phase; the second aqueous phase and main emulsion are secondarily emulsified; and the emulsified material is gelled to obtain the W1/O/W2 fat substitute. Advantageous effects are as follows: according to emulsification stability, the most suitable mass ratio of the inner and outer aqueous phase to the oil phase is explored; a special stepwise stirring method is used to promote emulsification; a double emulsification technique and gel properties of carrageenan areused to develop the solid |
