Description

Infant probiotic supplementing chewing gel and preparation method thereof
Technical Field
The invention belongs to the technical field of probiotic supplements, and particularly relates to a probiotic chewing gel for supplementing infants and a preparation method thereof.
Background
Probiotics are active microorganisms which have health effects on hosts after being ingested in certain amounts, and have various benefits on human bodies such as regulating intestinal flora, relaxing bowels, moistening stool, relieving inflammation and the like. The probiotics only reach the colon in sufficient quantity to exert the above effects. However, gastric acid and bile salts in the gastrointestinal tract are two major factors in stress probiotic survival, making the probiotics capable of reaching the colon in an active state severely deficient.
Embedding technology is an effective strategy to solve the above-mentioned problems. Entrapment is the reduction of probiotic inactivation in the gastrointestinal tract by enclosing the probiotic in a wall material, providing additional physical protection to the probiotic. The gel based on the biomacromolecule can effectively embed probiotics, and can realize the mild compatibility of the probiotics and the gel. The extensive research of the gel promotes the diversified development of the commodity type loaded with probiotics, and especially the probiotic jelly which is emerging in recent years is popular with consumers. However, while researchers have designed various gel types and structures to allow the loaded probiotics to exhibit better gastrointestinal tolerance, the necessary links to oral chewing that the gel presents when consumed by consumers are ignored. Chewing typically breaks the gel structure, re-exposing the probiotics to gastric acid and bile salt environments, and thereby losing the gel protecting effect. Therefore, how to combine the chewability of the gel with the high activity of the probiotics in the gastrointestinal tract is a critical issue to be solved by commercial products of gel-type probiotics.
In nature, microorganisms often form colonies that aggregate together to resist the harsh environment of the outside world. In this process, microorganisms develop quorum sensing effects by autocrine extracellular polymeric substances and transmitting intercellular molecular signals within the enclosed space, thereby achieving high resistance to external stress. In light of the above, we have resorted to gel structures to provide the necessary conditions for the formation of probiotic-mediated quorum sensing, thereby achieving the protective ability of the autocrine extracellular polymer to the bacterial cells. Thereby achieving a compromise between the chewability of the gel and the high activity of the probiotics in the gastrointestinal tract.
At present, the probiotic supplements are mostly carried out in the form of aqueous solution, the soft candy gel type supplements are carried out completely according to the chewing force of adults, and the probiotic supplements carried out by children are completely absent and cannot cope with the current problem of solving the probiotic supplements of infants

Example 11
The probiotic-loaded gels prepared in examples 1 to 10 were subjected to simulated chewing in the mouth, followed by gastric acid and cholic acid resistant survival measurements recorded in table 1, the measurements being as follows:
method for determining gastric acid-resistant survival rate: the gel after 0.5g of simulated chewing of the oral cavity (gel beads are broken for 5S by a nine-yang 8S speed stirring gear stirrer) is placed in vitro simulated gastric juice (pH=2) stirred at 600rpm for 2 hours, then placed in 5ml of 0.05M sodium citrate solution for vortex, then subjected to gradient dilution, mixed with solid culture medium by a pouring method, anaerobic cultured at 37 ℃ for 48 hours, and counted.
Gastric acid resistant survival = number of post gastric acid bacteria (CFU/g)/number of post freeze-drying bacteria (CFU/g) ×100%
Method for determining survival rate of cholic acid:
0.5g of gel after simulated chewing of the oral cavity was placed in an in vitro simulated bile salt solution (ph=6.8) stirred at 600rpm for 1 hour, then placed in 5ml of 0.05M sodium citrate solution, vortexed to release capsules, then diluted in gradient, poured into a mixed solid medium, anaerobic cultured at 37 ℃ for 48 hours, and counted.
Cholic acid survival = number of post cholic acid bacteria (CFU/g)/number of post freeze-drying bacteria (CFU/g) ×100%
Table 1 viability data and burst force of gel beads prepared in examples 1 to 10
In Table 1, example 9 did not give good results, probably because the strain was insufficient in the ability to autocrine extracellular polymer under this condition. The gel finished product prepared in the invention has obvious gastrointestinal tract tolerance to most probiotics after chewing, has a small advantage in bursting force, and is convenient to adapt to the chewing scene of infants.
The invention can still keep higher gastrointestinal tract survival rate after chewing in the mouth, has the characteristics of lower chewing and biting force requirement and convenience in digestion, and can have good probiotic supplementing effect on infants.
It should be noted that the above embodiments are only for illustrating the technical solution of the present invention and not for limiting the same, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solution of the present invention may be modified or substituted without departing from the spirit and scope of the technical solution of the present invention, which is intended to be covered in the scope of the claims of the present invention.
