Embodiment 1
[0024] 1) Preparation of water-in-oil-in-water emulsion containing soluble calcium salt
[0025] Add 0.02 g of sucrose fatty acid ester to 100 g of rapeseed oil, heat to 30° C. and stir to obtain an oil phase. Then, 0.5 ml of 0.1% calcium chloride solution and 9.5 ml of rapeseed oil containing sucrose fatty acid ester were heated to 80°C for mixing, and stirred at a speed of 300 rpm for 120 minutes with a high-speed disperser to obtain a water-in-oil emulsion .
[0026] An aqueous phase was prepared by adding 5 grams of sodium dodecyl sulfate to 100 grams of water. 0.5 ml of the prepared water-in-oil emulsion and 9.5 ml of the water phase were heated to 30° C. for mixing, and stirred at a speed of 24,000 rpm for 0.5 minutes with a high-speed disperser to obtain a water-in-oil-in-water emulsion containing soluble calcium salts.
[0027] 2) Preparation of a water-in-oil-in-water emulsion containing soluble phosphate.
[0028] Add 5 grams of sucrose fatty acid ester to 100 gra...

[0034]This example is the same as Example 1, except that the surfactants (other surfactants other than Example 1) used in the preparation of the water-in-oil emulsion are Span60, Span65, glyceryl stearate, water loss Sorbitol monostearate, sorbitan monopalmitate, sodium stearoyl lactylate, calcium stearoyl lactylate, glyceryl rosin, sucrose acetate, sucrose isobutyrate, Span80, polyoxyethylene xylitol Monostearate, Hydrogenated Rosin Glycerides, Diacetyl Tartaric Acid Mono and Diglycerides, Propylene Glycol Fatty Acid Esters, Dipolyglycerol Monostearate, Monoglycerides, Tripolyglycerides, Propylene Glycol Fatty Acid Esters, Soy Lecithin , one of lauric acid monoglyceride, or sucrose fatty acid ester, Span60, Span65, glyceryl stearate, sorbitan monostearate, sorbitan monopalmitate, sodium stearoyl lactylate , calcium stearoyl lactylate, rosin glyceride, sucrose acetate, sucrose isobutyrate, Span80, polyoxyethylene xylitol monostearate, hydrogenated rosin glyceride, diacetyl tar...
Embodiment 3
[0037] 1) Preparation of a water-in-oil-in-water emulsion containing a soluble calcium salt.
[0038] Add 0.1 g of glyceryl stearate to 2 g of sunflower oil, heat to 80° C. and stir to obtain an oil phase. Then 1.5 ml of 60% calcium nitrate solution and 1 ml of sunflower oil containing glyceryl stearate were heated to 30°C for mixing, and stirred at a speed of 24,000 rpm for 0.5 minutes with a high-speed disperser to obtain a water-in-oil emulsion .
[0039] Add 1 gram of sodium caseinate to 4 grams of water, and stir to obtain the water phase. 1.5 ml of the prepared water-in-oil emulsion and 1 ml of the water phase were heated to 80° C. for mixing, and dispersed at a speed of 300 rpm for 120 minutes with a high-speed disperser to obtain a water-in-oil-in-water emulsion containing calcium ions.
[0040] 2) Preparation of a water-in-oil-in-water emulsion containing soluble phosphate.
[0041] Add 0.5 g of glyceryl stearate to 2 g of sunflower oil, heat to 30° C. and stir to ...
