Embodiment 1

[0039] The present embodiment provides a method for preparing a Pickering emulsion co-stabilized by calcium carbonate and sodium alginate, comprising the following steps:

[0040] S1, accurately weigh 0.15g sodium alginate (molecular weight 179.5kDa, M / G ratio 0.56, viscosity 125.5mPa·s) and disperse it in 20g ultrapure water, and disperse it under 550r / min magnetic stirring for 90min to obtain a mass fraction of 0.75 wt% sodium alginate aqueous phase solution.

[0041] S2. Accurately weigh 1.7g of solid calcium carbonate particles with a particle size of 0.5-2μm, add it into the sodium alginate aqueous phase solution under stirring conditions, and disperse for 30min under the action of 550r / min magnetic stirring to obtain the sodium alginate aqueous phase containing calcium carbonate suspension.

[0042] S3, accurately weigh 4g of soybean oil, add it to the sodium alginate aqueous phase suspension containing calcium carbonate, the oil-water weight ratio is 1:5, and use a hig...

Abstract

The invention relates to a Pickering emulsion with high storage stability and its new application. The Pickering emulsion is mainly prepared from solid calcium carbonate particles, sodium alginate, vegetable oil and water through shear emulsification to form O / W lotion. The Pickering emulsion of the present invention can achieve the effect of maintaining the emulsion state for a longer time as a whole by adjusting the calcium carbonate and sodium alginate suspending emulsification process, and can be taken as an emulsion calcium supplement product.

Description

technical field [0001] The invention relates to a Pickering emulsion with high storage stability and its new application. Background technique [0002] Pickering emulsion refers to the emulsion obtained by using ultrafine solid particles as emulsifier. The solid powder used as emulsifier includes clay, silicon dioxide, metal hydroxide, graphite, carbon black, etc. [0003] In addition, the paper "Preparation, Optimization and Application of Calcium Carbonate-stabilized Pickering Emulsion" carried out amplified research, showing that the type of emulsifier solid powder can also be calcium carbonate. The paper discloses the following content: first, use heavy calcium carbonate as raw material to construct Pickering emulsion system; then add sodium alginate to calcium carbonate-stabilized Pickering emulsion for optimization; finally, apply the optimized emulsion to the fat-soluble bioactive substance turmeric In the entrapment and delivery of curcumin, the effect of the emulsi...
