Embodiment 1
[0032] Example 1: Preparation method of antifreeze multiple emulsifying gel composition
[0033] (1) Weigh glycerin, carrageenan, and gellan gum, add them to water, heat to fully swell, add soluble divalent salt, hydrophilic emulsifier, and mix well to form the external phase gel mother liquor.
[0034] (2) Weigh the solid oil, add lipophilic emulsifier, and heat it in a water bath until it melts completely, which is the mother liquid of the middle oil phase.
[0035] (3) The internal water phase is added to the mother liquor of the middle oil phase and emulsified by a homogenizer to obtain a W / O emulsion.
[0036] (4) The W / O emulsion is added to the external phase gel mother liquor and stirred to obtain the gel type W / O / W multiple emulsion mother liquor.
[0037] (5) The mother liquor of multiple emulsions is poured into the mold, completely frozen, demolded, and restored to room temperature, that is, multiple emulsion gels (or gel-type multiple emulsions).

Embodiment 2
[0041] Example 2: Performance comparison of different multiple emulsions
[0042] Sample 1, the antifreeze multiple emulsion gel of the present invention: (1) Weigh 90 g of glycerin, 3 g of carrageenan, 0.5 g of gellan gum, and 905.5 g of water, and heat to fully swell; weigh 1.2 g of calcium chloride and Tween -8030g, add and stir evenly, it is the mother liquor of the external phase gel; (2) Weigh 60g of shea butter, add 6g of Span-80, add and melt, it is the mother liquor of the middle oil phase; (3) Drop 30g into the middle layer The oil phase mother liquor was homogenized at 5000rpm for 10min to obtain the W / O emulsion; (4) The W / O emulsion was added to the external phase gel mother liquor and stirred at 1000rpm for 10min to obtain the gel type W / O / W multiple emulsion mother liquor; (5) 20g of the mother liquor of multiple emulsions, cooled to 4°C, ready for use; (6) Pour the mother liquor of multiple emulsions into a spherical mold, 20g each, and freeze completely at -80°C ...
