The brain DHA content experiment is carried out by taking rats as experimental objects, and the influence of the nutrition intelligence-improving and digestible and absorbable nutrition milk powder provided by the invention on the brain development of the rats is detected.
60 Rats of 100+ -10 g were selected and after one week of adaptive feeding, they were randomly divided into six groups of 10 animals each. Six groups of rats were normal feed group, example 1 group, example 2 group, example 3 group, comparative example 1 group, comparative example 2 group, respectively. Examples 1-3 groups were fed with the milk powder of examples 1-3, and group 1 was fed with the same milk powder of example 3, characterized in that no inulin, complex probiotics and l-carnitine component were contained, and group 2 was fed with the same milk powder of example 3, characterized in that no whey protein, DHA, AA, choline, inulin, complex probiotics and l-carnitine component were contained. The six groups of rats are continuously fed with 25g of the milk powder daily for 4 weeks, the weight is weighed once every three days, the rats are fasted for 12 hours after the last gastric lavage, the rats are anesthetized and the abdominal arteries are sacrificed after whole blood collection, brain tissues are separated, the total fat in the rats is extracted by chloroform-methanol solution (2:1, V/V) after homogenization, and the relative content of DHA in the total fatty acid is measured by a gas chromatography, and the results are shown in Table 4:
TABLE 4 Table 4
Conventional feed group Example 1 group Example 2 group Example 3 group Comparative example 1 group Comparative example 2 group
DHA(%) 9.53 12.80 12.55 13.25 11.24 9.74
The results in Table 4 show that compared with the control group, after rats eat the milk powder prepared by the invention, the DHA content in brain tissue fatty acid is obviously improved, which indicates that the DHA content in brain tissue of rats can be improved by eating the milk powder of the invention; the comparative example 1, in which the digestion promoting component was removed, showed that the DHA content in the brain was significantly inferior to that of the group of examples 1 to 3, indicating that the development of gastrointestinal function could promote the absorption of the intelligence promoting component by the organism, the comparative example 2, in which the intelligence promoting and digestion promoting component was removed, showed that the DHA content in the brain of rats was not much different from that of the conventional feed group. In conclusion, the digestion promoting component and the intelligence promoting component can play a synergistic role to effectively promote the brain development of rats.
Example 8
Comparative example 4 was set up as follows:
comparative example 4: the difference from example 3 is that inulin, complex probiotics and the l-carnitine component are absent.
Comparative example 5: the difference from example 3 is that whey protein powder is a normal whey protein powder without milk fat globule membrane.
Comparative example 6: the difference from example 3 is that whey protein, DHA, AA, choline, inulin, complex probiotics and L-carnitine components are absent.
Nutritional milk powder in the above comparative examples 4 to 6 was prepared according to the preparation method of example 3.
70 Rats of 100+ -10 g were selected and after one week of adaptive feeding, they were randomly divided into seven groups of 10 animals each. Seven groups of rats were normal feed group, example 1 group, example 2 group, example 3 group, comparative example 4 group, comparative example 5 group, comparative example 6 group, respectively. Examples 1-3 groups were fed with the milk powder of examples 1-3 and comparative examples 4-6 groups were fed with the milk powder of comparative examples 4-6. The six groups of rats were continuously fed with 25g of the above milk powder daily for 4 weeks, and after the last feeding, bench jump tests were performed, respectively.
Jump test: the rats were placed in a reaction box for 3min, and then stimulated with 36V ac power. The rats were then placed on an insulated platform and the latency of each rat to jump off the platform for the first time, the number of mistakes per rat to jump off the platform in 5min and the number of animals to jump off the platform for each group (memory acquisition) were recorded. The test was repeated 24 hours later, and the latency of the first jump-down platform, the number of errors of the jump-down platform within 3 minutes and the number of animals (memory consolidation) of each group of jump-down platforms were recorded, and the experimental results are shown in table 5.
TABLE 5
As can be seen from table 5, taking the milk powder of the present invention can significantly improve the memory acquisition and memory consolidation ability of rats, it can be inferred that the milk powder of the present invention can promote the brain development of rats, thereby improving the comprehension and memory ability of rats; after the absorption promoting components are removed, the memory acquisition and memory consolidation capacity of the rats are improved compared with those of the conventional feed group, but the effects are not obvious and are not as good as those of the groups 1-3; after replacing whey protein powder rich in milk plasma globule membrane with conventional whey protein powder, rat brain development was inferior to that of examples 1-3 of the present invention; after removing the intelligence-improving and absorption-promoting components, the memory acquisition and memory consolidation capability of the rats are comparable to those of the conventional feed group.
