In the composition, glucuronolactone is converted into glucuronic acid under the catalysis of enzyme, bilirubin is combined with the glucuronic acid to form combined bilirubin, the physicochemical property of the bilirubin is changed, and the combined bilirubin is changed from fat-soluble unconjugated bilirubin with very low polarity into water-soluble conjugate-glucuronic acid bilirubin with relatively high polarity; combining with bilirubin, discharging into intestine via liver and bile, removing glucuronic acid under the action of intestinal bacteria, and changing into urobilinogen; most of the urobilin is oxidized into urobilin which is discharged from the excrement, and the urobilin is called as fecal bilin; part of urobilinogen is absorbed by intestine and returned to liver, and most urobilin returned to liver is converted into combined bilirubin, and then discharged into intestine along with bile to form 'enterohepatic circulation of bilirubin'; the remaining small part of urobilinogen is discharged from the kidney through the systemic circulation. On the other hand, chitosan can absorb intestinal unconverted bilirubin, thereby excreting bilirubin out of the body, reducing small intestinal reabsorption of bilirubin, and promoting "enterohepatic circulation of bilirubin" formed from glucuronolactone. The glucuronolactone and the chitosan in the composition of the invention act synergistically to accelerate the metabolism of bilirubin, thereby achieving the effect of preventing and improving neonatal jaundice.
Further, in the composition of the present invention, selenium can regulate immunity and protect liver, and the lack of selenium can cause impaired liver function; the probiotic bacteria can promote the combined bilirubin to be converted into urobilinogen and urobilin, so that the bilirubin is excreted out of the body through the excrement.

The formula milk powder obtained in the above examples and comparative examples is tested for jaundice prevention and improvement effects, and the test method and results are as follows:
1. test method
220 mice of 6-8 weeks old were randomly divided into 11 groups of 20 mice each, and divided into male and female halves, a blank group, a model group, a control group, examples 1-3, and comparative examples 1-5.
The control group, examples 1 to 3 and comparative examples 1 to 5 were each administered with corresponding milk powder to mice, and the model group and the blank group were not administered with milk powder as food. Feeding continuously for 10 days. 2h after administration on the eighth day, the milk powder group and the model group were each administered with 0.4% ANIT olive oil solution (100mg/kg), the blank group was administered with the same volume of olive oil, the material was taken after 48h, fasting was not performed for 12h before the material was taken, after the mice were sacrificed after cervical vertebrae were removed, 1 liver tissue of 1.0 × 0.8 × 0.3cm size was excised from the right leaf of the liver, fixed with 10% neutral formalin, dehydrated, embedded, sliced, and observed for histopathological changes by hematoxylin-eosin staining (HE staining). And taking another liver, preparing homogenate by using cold normal saline, and detecting the liver homogenate cholesterol (Tc), Triglyceride (TG) and Malondialdehyde (MDA) according to the kit instruction.
During the experiment, the mice of each group are fed with milk liquid (prepared from milk powder and warm water at a ratio of 6: 1) and replaced every 12h to ensure the freshness of the milk liquid, and the residual milk amount is measured and recorded when the milk liquid is replaced every time. In order to ensure the nutrition supply of the mice, the milk is given and the feed is given at the same time, and the milk feeding ratio is 7: 3.
2. Statistical processing method
The measured data are expressed by mean ± standard deviation, and data processing is performed by using an SPSS18.00 software package. If the data are normally distributed and the variance among the groups is uniform, the data are processed by one-way ANORVA, the results are expressed as mean + -standard deviation, and multiple comparisons are performed by LSD method. The difference is statistically significant when P is less than or equal to 0.05.
3. Test results
Table 1 shows the effect of different formula milk on the index of the hepatitis model liver of the mouse jaundice model.
TABLE 1
Figure BDA0003381735450000071
Figure BDA0003381735450000081
As can be seen from Table 1, the levels of Total Cholesterol (TC), Triglyceride (TG) and Malondialdehyde (MDA) in the liver of the model group were significantly increased (P < 0.01) compared to the blank group, indicating the success of icterohepatitis.
Compared with a model group and a control group, the TC/TG/MDA level (P is less than 0.05) of the liver can be obviously reduced in examples 1-3, wherein the addition amount of chitosan in the examples 1-3 is respectively 0.4 part, 0.2 part and 1 part, the ratio of chitosan: sialic acids were all 1: 2. The experimental data show that the larger the addition amount of chitosan, the more effective the jaundice improvement. Comparative example 1 only 0.4 part of chitosan was added and comparative example 2 only 0.2 part of sialic acid was added, and by comparing with example 1, addition of chitosan alone reduced the liver TC/TG/MDA level, but the effect was significantly lower than example 1, and addition of sialic acid alone had almost no effect, which was not substantially the same as comparative example. Comparative example 3 and comparative example 4 both added 0.4 parts of chitosan but at different ratios of chitosan to sialic acid, 10:1 and 0.1:1 respectively. It was found by the data that less sialic acid was added (as in comparative example 3) and the jaundice reducing effect was significantly weaker than in example 1. While comparative example 4 is slightly superior to example 1, indicating that too much polysialic acid added does not have much advantage in improving jaundice.
