[0171] As can be seen from Table 1, compared with Comparative examples 1 to 3, the number of viable bacteria in each of Examples 1 to 9 was more than 10.sup.8, indicating that the probiotics in the microspheres had good acid resistance. As can be seen from Table 2, in Examples 1 to 9, the embedding rates of probiotics and vitamins were more than 80% respectively, the embedding rate of minerals was more than 70%, the embedding rate of prebiotics was more than 75%, and the embedding rate of nutrients in the microspheres was good. As can be seen from Tables 3, 4, 5 and 6, the probiotics, vitamins, minerals and prebiotics had good storage stability. As can be seen from FIG. 3, compared with Comparative example 3, the swelling rate and elastic modulus were good in Examples 1 to 9. As can be seen from FIG. 4, the survival number of probiotics in the preparation process of microspheres increased first and then decreased with the increase of the concentration of the enteric coating material, and the survival number of probiotics reached a maximum value when the concentration of the enteric coating material was 8%. As can be seen from FIG. 5, the microspheres were basically completely released while staying in the artificial intestinal fluid for 30 min, and can stably exist in the artificial intestinal fluid. As can be seen from FIG. 6, different laser punching methods had a great influence on the disintegration time of the capsule, among which two holes in symmetrical positions in the middle of the waist of the capsule shell with an aperture of 1 mm are the most suitable, which greatly increases the disintegration speed. As can be seen from FIG. 7, the weights of adult male and female rats changed significantly after taking this capsule, with a weight loss of 14.11% and 10.73% respectively after 2 months.
