Abstract
The invention pertains a way of producing milk powder having active bacillus. Its addiction is bacillus and oligosaccharide. It can product milk powder having the function of increasing immunity improve intestinal tract. This kind of milk powder contains bacillus over 10cfu/gram, water below 5%.
Description
[technical field]
The present invention relates to a kind of milk powder product that contains active Bifidobacterium and isomalto-oligosaccharide and preparation method thereof.
[background technology]
Bifidobacterium (Bifidobacterium) is an important physical bacterium in the humans and animals enteron aisle, and having of it is beneficial to the gastral health status of raising humans and animals.Modern numerous studies show that: the alimentary canal microorganism is playing an important role aspect health and the disease, for example nutrition, physiological function, efficacy of drugs, cancer, immune response, aging etc. all closely related with archenteric flora.Bifidobacterium produces organic acid in metabolic process, the effect of inhibition enteron aisle saprophytic bacteria growth is arranged, thereby plays effects such as regulating gut flora, control diarrhoea, the vitamin metabolism of improving, raising immunity function, and health is had multinomial beneficial functional.
Bifidobacterium is large numbers of normal beneficial microbes in the human body intestinal canal, and human body is from the physiological change process in baby, child, teenager, youth, the prime of life to old age, and Bifidobacterium quantity reduces gradually in the intestines, and microbe species also has replacement and changes.When the people was dead, Bifidobacterium at first lost activity in the intestines.Under normal circumstances, Bifidobacterium and the peaceful coexistence of other floras, keep and adjust the microecological balance of human body together, make human body be in good health status, what all link closely with growth, metabolism and even the birth and old age, sickness and death of human body the Bifidobacterium content in the human body.Many paathogenic factors all can make the normal intestinal flora imbalance simultaneously, and cause long-term diarrhea, use the enteron aisle antibiotic invalid sometimes merely, and some cases also can increase the weight of the imbalance of gut flora.Therefore the quantity of replenishing and keep the active Bifidobacterium in the human body for improve the human immunologic function, improve vitamin metabolism, to strengthen health significant.
Modern age, how countries in the world all began one's study active Bifidobacterium as food additives, with the problem of manual method with this class viable bacteria food prepared therefrom.But because bifidobacterium growth condition harshness, its suitable growth temperature is 35～40 ℃, and the pH value is 6.5～7.0, and obligate anaerobic.Therefore to make the oral active Bifidobacterium can field planting and breeding in human body intestinal canal, must accomplish 2 points: the one, by the human stomach time, do not killed by hydrochloric acid in gastric juice; The 2nd, the active Bifidobacterium of sufficient amount be arranged, it improves the human immunologic function competence exertion, improves vitamin metabolism, strengthens the effect of health.The many restrictions of Bifidobacterium oral liquid in the market or food because of conditions such as culture process, processing methods, ubiquity survival bacterium amount is not high, shortcomings such as viable bacteria storage life weak point, thereby do not reach desirable health care purpose.
The present inventor finds, Bifidobacterium freeze-dried powder and isomalto-oligosaccharide will be added in the milk powder, can improve the ability of active Bifidobacterium field planting and breeding in human body intestinal canal, and keep sufficient amount, improve the human immunologic function, improve vitamin metabolism, strengthen the effect of health thereby really played.
