Description

Carotenoid preparation, and preparation method and application thereof

Technical Field

The invention relates to the technical field of particle preparation, and particularly relates to a carotenoid preparation, and a preparation method and application thereof.

Background

Carotenoids (carotenoids) are yellow, orange-red or red polyenes, generally composed of 8 isoprenoid units, of the formula C₄₀H₅₆. Carotenoids are known to have beneficial effects on health, and are physiological antioxidants that block lipid peroxidation and thus protect the follicular and uterine steroidogenic cells from oxidation. The carotenoid is provitamin A, and has effects of preventing nyctalopia, resisting oxidation, preventing cancer, and improving tinting strength. However, carotenoids are insoluble in water, have low solubility in fats and oils, and are unstable to light, oxygen, and heat, thereby limiting their applications. Conventional methods improve the bioavailability and also the coloring power of encapsulated products formed by microencapsulation of carotenoids, for example, some beautiful cakes and beverages are derived from carotenoids.

Meanwhile, the improvement of the coloring capability brings troubles, for example, the product is easily dyed on hands, clothes and even faces, and after the carotenoid product is taken, the surface of the tongue and a cup are also dyed, so that a bad experience is brought to people. None of the methods can maintain the biological activity of the carotenoid, reduce the dyeing ability of the carotenoid, and the like, so that the carotenoid can be better used by people, and is a problem which is considered by researchers in the field. A common solution to this problem is to crosslink the gelatin or protein to give crosslinked beads.

For example, patent GB993138 discloses a method for stabilizing gelatin-containing vitamin products, in which formaldehyde, glutaraldehyde, or the like is used as a crosslinking agent, and heat treatment is performed.

Patent CN1283454A, provides a method for preparing beads of fat-soluble substances by crosslinking gelatin using radiation or glutaminase, followed by spray drying into starchy powder.

Patent CN1764439A, provides a method for preparing crosslinked beads, which are crosslinked at 90-140 ℃ for 30 seconds-30 minutes.

The main problem of these patents is that high temperatures are used for crosslinking and the crosslinking time is too long, thus destroying the fat-soluble ingredients or carotenoids which are not stable.

Patent CN1303670A provides a powdered stable vitamin and/or carotenoid product and a preparation method thereof, which uses an alkali metal phosphate cross-linking agent to cross-link protein materials such as gelatin, casein and the like, and achieves the effect of insolubilization in water at 100 ℃ within 3 min. Although it is claimed to lower the thermal crosslinking temperature, the actual preparation process still uses the condition that the heating temperature is 55-180 ℃.

The above patent solves or partially solves the problem of water solubility of carotenoids, but uses gelatin and protein, which are obviously crosslinked to partially achieve the purpose of reducing pigment dissolution. However, the prior art does not describe how to prepare products of carotenoid preparations using other types of wall materials.

According to the technical scheme of the comparative example 5, through the combination of the octenyl sodium starch succinate and the glucose, the release degree of the obtained product is superior to that of the technical schemes of the examples 1 to 4, but the dissolution rate is poor, and according to the analysis of effect data, the pigment dissolution rate of the product obtained according to the technical scheme of the comparative example 5 is 3.1% which is 8-15 times of the pigment dissolution rate (0.2-0.4%) of the products obtained in the examples 1 to 4, so that the technical scheme of the application is far superior to that of the prior art in the aspect of improving the pigment dissolution rate of the product, and has extremely remarkable effect improvement.

Comparative example 6

178g of zeaxanthin crystals and 3 times of 60% ethanol aqueous solution are mixed, stirred at 45 ℃ for 30min, then subjected to high-speed shearing dispersion at 10000 revolutions, added with 20g of ascorbic acid, 1g of ascorbyl palmitate and 1g of sucrose fatty acid ester, subjected to solvent removal at 75 ℃, 7ppm of ethanol residues and 12.8% of water content of the crystals, and frozen at-20 ℃ for later use.

Comparative example 8

200g of lutein ester crystals and 3 times of 60% ethanol aqueous solution are mixed, stirred for 30min at 45 ℃, then subjected to high-speed shearing dispersion at 10000 revolutions, added with 20g of ascorbic acid, 1g of ascorbyl palmitate and 1g of sucrose fatty acid ester, subjected to solvent removal at 75 ℃, and subjected to ethanol residue removal of 7ppm, wherein the water content of the crystals is 10%, and then frozen at-20 ℃ for later use. The gelling wall material compositions in the table are respectively added, and the product effect is shown in the following table 3 after the treatment according to the gelling method in the example 2:

TABLE 3 comparison of dissolution effects using different gelling wall materials

In contrast, the combination of a wall material (corn starch or hydroxypropylmethyl cellulose) and a carbohydrate alone is not effective. And the formula does not contain carbohydrate, so the effect is poor. The effect of the formula in which corn starch and Arabic gum are used as wall materials and are gelatinized together with sucrose is also poor. The experimental group using hydroxypropylmethylcellulose having a high viscosity as a wall material also did not achieve the expected effect.
