Description

Technical Field

[0001] The present invention relates to the technical field of food and its preparation, and in particular to a functional lutein chewable tablet and a preparation method thereof. Background Art

[0002] Most herbs are being developed into nutritional products due to their high safety and low side effects. Chewable tablets made from ingredients such as Ganoderma lucidum, ginseng, maca, and Pueraria root not only ensure the functionality of the product and meet people's intake needs, but also improve the taste and have high economic and social value. The development and research of chewable tablets with specific nutritional auxiliary functions is a development trend in the context of big health and is a product with great market competitive advantages.

[0003] Lutein is a carotenoid that can be extracted from certain plants at high concentrations. Lutein has antioxidant activity and can absorb harmful light, such as blue light. It is also the primary pigment in the macula of the human retina. It can alleviate and protect against vision loss and blindness caused by retinal pigment degeneration, and is therefore often used as an eye protection ingredient in food and health supplements.

[0004] However, since lutein is sensitive to light, heat and oxygen, easily oxidized under natural conditions and difficult to dissolve in water, its application is subject to certain restrictions. Among them, functional chewable tablets containing lutein also have the problem of easy degradation and oxidation of lutein and poor stability after tableting. Summary of the Invention

[0005] The present invention provides a functional lutein chewable tablet and a preparation method thereof, which solves the problem of poor stability of functional lutein chewable tablets in the related art.

[0006] The technical solutions of the present invention are as follows:

[0007] The present invention provides a functional lutein chewable tablet comprising the following components in parts by weight: 10-20 parts of lutein, 3-5 parts of an emulsifier, 30-50 parts of vegetable oil, 50-60 parts of a filler, 2-4 parts of steviol glycosides, 3-5 parts of sodium carboxymethyl starch, and 2-4 parts of magnesium stearate; the emulsifier comprises octenyl succinate starch, sodium stearoyl lactylate, and citric acid fatty acid glyceride.

[0008] As a further technical solution, the mass ratio of the octenyl succinate starch ester, sodium stearoyl lactylate and citric acid fatty acid glyceride is 1-3:2:1.

[0009] As a further technical solution, the filler is a mixture of corn starch and xylitol.

[0010] As a further technical solution, the mass ratio of the corn starch to xylitol is 7:3 to 9:1; preferably, the mass ratio of the corn starch to xylitol is 8:2.

[0011] As a further technical solution, the vegetable oil is one of peanut oil, corn oil, rapeseed oil, soybean oil, and olive oil.

[0012] The present invention also provides a method for preparing a functional lutein chewable tablet, comprising the following steps:

[0013] S1. Adding an emulsifier to water, stirring and dispersing the mixture to obtain an aqueous phase;

[0014] S2, adding lutein to vegetable oil and ultrasonically dispersing it to obtain an oil phase;

[0015] S3, adding the oil phase to the water phase, shear mixing, emulsifying and homogenizing, and spray drying to obtain modified lutein;

[0016] S4, mixing the modified lutein with the filler and half the mass of magnesium stearate to obtain a mixture A;

[0017] S5. Mix the mixture A, steviol glycoside, sodium carboxymethyl starch and the other half of the weight of magnesium stearate, press into tablets, and dry to obtain functional lutein chewable tablets.

[0018] As a further technical solution, the mass ratio of the emulsifier to water in S1 is 1:20.

[0019] As a further technical solution, the stirring time in S1 is 40 to 60 minutes; and the ultrasonic time in S2 is 30 to 40 minutes.

[0020] As a further technical solution, the shear mixing speed in S3 is 8000-10000 r / min, the mixing time is 3-5 min, the emulsification and homogenization time is 5-15 min, and the emulsification and homogenization pressure is 20-50 MPa.

[0021] As a further technical solution, the mixing time in S4 is 50-80 min, and the mixing time in S5 is 30-40 min.

[0022] The working principle and beneficial effects of the present invention are:

[0023] 1. In the present invention, octenyl succinate starch ester and sodium stearoyl lactylate are compounded with citric acid fatty acid glyceride as emulsifiers, combined with vegetable oil to protect lutein from degradation and oxidation. The functional lutein chewable tablets prepared by combining fillers and other components not only have the function of relieving eye fatigue, but also have high stability and a sweet and sour taste.

[0024] 2. In the present invention, corn starch and xylitol are used synergistically as fillers for the functional lutein chewable tablets. By regulating the mass ratio of corn starch and xylitol, the stability of the functional lutein chewable tablets can be significantly improved and the storage period can be extended.

[0025] 3. In the present invention, the lutein treated with an emulsifier and vegetable oil is first mixed with a filler and half the mass of magnesium stearate, and then mixed with other components and the other half the mass of magnesium stearate, so that the lutein and other components are more evenly dispersed, thereby improving the stability of the functional lutein chewable tablet.

[0088] Experiment 2: Stability test of functional lutein chewable tablets

[0089] The functional lutein chewable tablets prepared in Examples 1 to 3 and Examples 7 to 13 were tested for hardness and friability. For friability, the tablets were blown away with a hair dryer to remove powder falling off, accurately weighed, placed in a cylinder, and rotated 100 times. No broken, cracked, or crushed tablets were detected. The friability was calculated by weighing, as shown in the following table:

[0090]

[0091] By comparing the data of Examples 1 to 3 and Examples 7 to 13, it was found that the hardness of the functional lutein chewable tablets of Examples 1 to 3 and Examples 7 to 8 was higher than that of Examples 9 to 10 and Examples 12 to 13, and the friability was lower than that of Examples 9 to 10 and Examples 12 to 13, indicating that corn starch and xylitol synergistically serve as fillers for the functional lutein chewable tablets, and that the stability of the functional lutein chewable tablets can be significantly improved by regulating the mass ratio of corn starch to xylitol; the hardness of the functional lutein chewable tablet of Example 3 was higher than that of Example 11, and the friability was lower than that of Example 11, indicating that the stability of the functional lutein chewable tablets was improved by first adding half the mass of magnesium stearate and then adding the other half of the mass of magnesium stearate for mixing.

[0092] Experiment 3

[0093] 50 volunteers who frequently use computers and suffer from visual fatigue were recruited and asked to take one functional lutein chewable tablet prepared in Example 11 daily for 30 consecutive days. The taste of the functional lutein chewable tablet and the effect of alleviating eye fatigue were evaluated.

[0094] The taste evaluation indicators are shown in the following table:

[0095]

[0096] Among them, 50 volunteers were asked to rate the taste, and the results were averaged; the rate of eye fatigue relief = (number of people whose eye fatigue was relieved / 50) × 100%. The evaluation results are shown in the following table:

[0097]

[0098] The evaluation results show that the prepared functional lutein chewable tablets have a good taste, moderate sweetness and sourness, and can effectively relieve eye fatigue.
