Embodiment 1

[0024] First, dissolve 500g of maltodextrin and 30g of sodium caseinate in 1500ml of water at 62°C, then slowly add 5g of sodium stearoyl lactylate and 5g of glyceryl mono- and distearate, and keep stirring to dissolve. Slowly add 460g of oily zeaxanthin preheated to 62°C into the mixed solution, and at the same time carry out high-speed shear homogenization until the mixed solution is stable and not stratified, and then sprayed into a high-speed spray dryer for spray drying, and the inlet temperature is 125 °C, the outlet air temperature is 75 °C. Obtain 985g zeaxanthin microcapsules.

[0025] It has been determined that the microcapsule zeaxanthin content is 46%, and it can be rapidly dispersed in water into a uniform and clear solution.

Embodiment 2

[0027] First, dissolve 600g of maltodextrin and 40g of sodium caseinate in 1800ml of water at 64°C, then slowly add 6g of sodium stearoyl lactylate and 7g of glyceryl mono- and distearate, and keep stirring to dissolve. Slowly add 347g of oily zeaxanthin preheated to 64°C into the mixed solution, and at the same time carry out high-speed shear homogenization until the mixed solution is stable and not stratified, then it is sprayed into a high-speed spray dryer for spray drying, and the inlet air temperature is at 140°C, the outlet air temperature is 80°C. Obtain 991g zeaxanthin microcapsules.

[0028] The content of zeaxanthin in the microcapsules is determined to be 34.7%, and it can be rapidly dispersed in water into a uniform and clear solution.

Embodiment 3

[0030] First, dissolve 400g of maltodextrin and 20g of sodium caseinate in 1200ml of water at 60°C, then slowly add 4g of sodium stearoyl lactylate and 3g of glyceryl mono- and distearate, and keep stirring to dissolve. Slowly add 300g of oily zeaxanthin preheated to 60°C into the mixed solution, and at the same time carry out high-speed shear homogenization until the mixed solution is stable and not stratified, then it is passed into a high-speed spray dryer for spray drying, and the inlet air temperature is at 140°C, the outlet air temperature is 80°C. Obtain 719g zeaxanthin microcapsules. The content of zeaxanthin in the microcapsules was determined to be 41.3%, and it can be quickly dispersed in water into a uniform and clear solution.

[0031] The color value of the corn yellow pigment microcapsules of Examples 1-3 was detected respectively, and the loss of color value after one year of airtight storage was less than 1%, indicating that the microcapsule product had good ...

Abstract

The invention relates to a preparation method of maize yellow pigment microcapsules. A core material is maize yellow pigment, and wall materials are maltodextrin and sodium caseinate. A mass ratio of the core material to the wall materials is 1:1-3. A combination of sodium stearyl lactate and single and double stearic acid glyceride is adopted as a compound emulsifying agent. maltodextrin and sodium caseinate are dissolved into water with a temperature of 55-65 DEG C; the sodium stearyl lactate and single and double stearic acid glyceride are added; the mixture is stirred until dissolved; maize yellow pigment preheated to 55-65 DEG C is added, and the mixture is homogenized; and spray-drying is carried out, such that maize yellow pigment microcapsule powder is obtained. With the method provided by the invention, the obtained produce can be well dispersed in water, and the emulsion is stable. The method provided by the invention has the advantages of simple equipment, low energy consumption, and environment friendliness.

Description

technical field [0001] The invention relates to a preparation method of zeaxanthin microcapsules. Background technique [0002] The main components of zeaxanthin are carotenoids, which are composed of lutein, zeaxanthin and β-carotene. Zeaxanthin is a functional natural food coloring with relatively high utilization value. They exist in the corn endosperm in the form of natural fat, have high nutritional value, and are easy to develop and utilize. my country and other countries in the world use zeaxanthin as a food additive in margarine, butter, cakes and candies, and it has a great market prospect. my country's food hygiene standard GB2760-1986 stipulates that corn yellow pigment is allowed as a food additive. It has been used in margarine, butter, cakes and candies abroad. Carotenoids have the effect of scavenging free radicals and can protect the human body from Damage caused by the action of monooxygen and free radicals. Fecal carotene also has the function of preventi...
