Embodiment 1

[0022] Embodiment 1, the preparation method of calcium stearoyl lactylate of the present invention

[0023] Add 400mol lactic acid into water, the weight ratio of lactic acid to water is 1:1.5, stir evenly, then add 133mol calcium carbonate, stir at 60°C for 1h, then add 200mol stearic acid and 18mol polyethylene glycol-400, at temperature React at 165°C for 2 hours under a vacuum of 0.08 MPa. After the reaction is complete, the product is recrystallized with absolute ethanol, and after vacuum drying, calcium stearoyl lactylate is obtained. The obtained calcium stearoyl lactylate is a milky white flaky solid.

Embodiment 2

[0024] Embodiment 2, the preparation method of calcium stearoyl lactylate of the present invention

[0025] Add 250mol lactic acid into water, the weight ratio of lactic acid to water is 1:1, stir evenly, then add 100mol calcium carbonate, stir at 55°C for 1.5h, then add 200mol stearic acid and 20mol polyethylene glycol-400, in React at a temperature of 160°C and a vacuum of 0.09MPa for 3 hours. After the reaction is completed, the product is recrystallized with absolute ethanol, and after vacuum drying, calcium stearoyl lactylate is obtained. The obtained calcium stearoyl lactylate is a milky white flaky solid.

Embodiment 3

[0026] Embodiment 3, the preparation method of calcium stearoyl lactylate of the present invention

[0027] Add 400mol lactic acid into water, the weight ratio of lactic acid to water is 1:2, stir evenly, then add 100mol calcium carbonate, stir at 65°C for 1h, then add 100mol stearic acid and 8mol polyethylene glycol-400, at temperature React at 180°C for 2.5 hours under a vacuum of 0.07MPa. After the reaction is complete, the material is discharged. The product is recrystallized with absolute ethanol, and after vacuum drying, calcium stearoyl lactylate is obtained. The obtained calcium stearoyl lactylate is milky white flaky solid.

Abstract

The present invention discloses a calcium stearoyl lactylate preparation method. The method comprises the following steps of adding lactic acid into water, evenly stirring the lactic acid and the water, adding calcium carbonate, stirring the mixture for 1-1.5 h at the temperature of 55-65 DEG C, adding stearic acid and polyethylene glycol-400, carrying out reaction for 2-3 h at the temperature of 160-180 DEG C and with a vacuum degree of 0.07-0.09 MPa, discharging the product after the reaction ends, recrystallizing the product by using absolute ethyl alcohol, and carrying out vacuum drying, thereby obtaining calcium stearoyl lactylate. The preparation method is high in yield; the reaction condition is mild; the production cycle is short; the energy consumption is low; and the production cost is low. Meanwhile, the invention further provides an emulsified composition. The emulsified composition comprises the calcium stearoyl lactylate prepared by the method, propylene glycol monostearate and polyoxyethylene sorbitan monostearate. The emulsified composition may be applied to milk beverage, and can improve the stability of the milk beverage.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a preparation method and application of calcium stearoyl lactylate. Background technique [0002] Calcium stearoyl lactylate [CSL] milky white powder or flake solid, can be well dispersed in hot water, soluble in ethanol and hot oil, has a pleasant caramel smell, is an anionic emulsifier. Calcium stearoyl lactylate and sodium stearoyl lactylate have similar structures and properties. However, the current research on the synthesis of calcium stearoyl lactylate is relatively small. Zhang Yali has studied the preparation process of calcium stearoyl lactylate. The research process is : In the reaction kettle, add L-lactic acid, stearic acid and catalyst according to a certain ratio, heat and stir, and control the reaction temperature at about 110°C until no water volatilizes. After the reaction is completed, cool down and slowly add calcium hydroxide to neutrali...
