Embodiment 1

[0041]Weigh 30 g of lutein crystals (purchased from Shaanxi Senfu Biotechnology Co., Ltd.) and dissolve them in 120 mL of edible alcohol, and add 0.5% sucrose ester 13 to make a core material solution; Add 3.2L of water to sucrose (the ratio of sucrose is 10%), stir and dissolve at 55°C to make it swell and disperse to make a wall material solution; add the core material solution to the wall material solution, stir and mix well , the obtained mixed solution was homogeneously emulsified twice in a colloid mill, and then spray-dried at a feed rate of 400mL / h and an inlet and outlet air temperature of 160 / 80°C to make a tangerine with a trans-lutein content of 4.8%. Yellow lutein microcapsule powder, microcapsule efficiency and yield are 91.12% and 90.30% respectively. The obtained product has fine and uniform particles, no peculiar smell, a solubility of 93%, and a water content of 4.2%.

Abstract

The invention relates to a xanthophyll-reinforced sweet corn beverage prepared by adding a xanthophyll microcapsule into sweet corn juice. A trans-xanthophyll crystal is taken as a core, starch octenylsuccinate and sucrose are taken as wall materials, the xanthophyll microcapsule is prepared by the processes of emulsifying, homogenizing, spray drying and the like, the efficiency and yield of the product microcapsule can reach 90 percent respectively, and the microcapsule has high quality. A preparation method comprises the following steps of: unfreezing quick-frozen sweet corn kernels serving as a raw material, pulping, regulating the pH, performing enzymolysis, filtering, adding a compound stabilizer (xanthan gum and sodium alginate), fructose, citric acid, sodium ascorbate and the xanthophyll microcapsule for mixing, and sterilizing and filling to obtain the xanthophyll-reinforced sweet corn beverage. The sweet corn beverage has unique flavor, fine and smooth mouthfeel and rich nutrition, has certain effect of preventing and treating impaired vision and blindness caused by age-related macular degeneration (AMD), and is particularly suitable for old people; and 100g of sweet corn beverage comprises 2.03mg of trans-xanthophyll, and the trans-xanthophyll content is higher than that of the common sweet corn beverage.

Description

technical field [0001] The invention relates to a lutein-enhanced sweet corn beverage and a preparation method thereof, belonging to the technical field of food processing. Background technique [0002] Lutein, an oxygenated carotenoid, is widely found in vegetables, flowers, fruits and certain algal organisms, especially in marigold flowers. The all-trans chemical conformation of lutein is the most stable, and the activity of the trans conformation in vivo is also much higher than that of the cis conformation. Because lutein can absorb a large amount of blue light close to ultraviolet light, it can filter blue light that damages photoreceptors and retinal pigment epithelium, and timely supplementation of lutein can prevent vision loss and blindness caused by age-related macular degeneration (AMD). In addition, lutein also has physiological functions such as anti-oxidation, anti-cancer, anti-mutagenesis, and delaying arteriosclerosis. It is a functional pigment with natural...
