Description
Technical field
The invention belongs to milk powder technical field, specially a kind of probiotics modulation milk powder and preparation method thereof.
Background technology
Human body can be gradually decreased with the increase at age, internal beneficial bacterium.In general, internal flora after people in middle age
Structure compared with the flora of children and youth, (wrap by beneficial bacterium (Bacillus acidi lactici and Bifidobacterium) negligible amounts, clostruidium
Include bacillus aerogenes capsulatus) it is higher, streptococcus and enterobacteria quantity are also higher.The reduction of beneficial bacterium in human body, can lead
Cause to be produced in enteron aisle and contain substantial amounts of putrefaction such as amine, phenol and indoles etc., and the synthesis of B family vitamin can also be reduced, and be entered
And there are various intestines problems.
Probiotics is that a class is beneficial to the microorganism of health.Research shows that there is probiotics regulating intestinal canal flora to put down
The effects such as weighing apparatus, promotion intestinal health, alleviation lactose intolerance, reduce serum cholesterol, enhance immunity.And milk powder is probiotics
Good carrier, the low moisture activity of milk powder, oxygen barrier packaging is not only suitable for the normal temperature of probiotics, and long shelf life is preserved.And
Rich in protein and fat are colonized also beneficial to protection probiotics by human gastrointestinal tract environment on intestinal mucosa in milk powder.
Probiotics colonizes in enteron aisle, with regulating intestinal canal flora, can suppress the propagation of harmful bacteria, reduces generation or the product of harmful substance
It is tired.
Prebiotics (such as inulin, stachyose, polyfructosan) is a kind of prebiotics for being conducive to human body intestinal canal healthy, is demonstrate,proved
It is bright to help to adjust functions of intestines and stomach, promote B family vitamin synthesis, the generation of enteral corrupt substance is reduced and suppresses, and suppression has
The propagation of evil bacterium, promotes the propagation of beneficial bacterium Bacillus acidi lactici and Bifidobacterium, promotes the absorption of mineral matter, promotes defecation etc. to make
With.Oryzanol is a kind of natural organic-compound rich in rice bran oil, is made up of ten several sterols ferulic acid esters
One compounds of group.Research shows, oryzanol energy reduction blood fat, the absorption of resistance cholesterol, reduce serum cholesterol, prevents lipid
Oxidation, prevention of cardiovascular disease etc. are acted on.
Milk powder this inherently matrix with abundant nutrition material, by improving lipid structure, improves albumen composition, adds
Plus micronutrient, prebiotics and probiotics, it more nutrition and is beneficial to health.Such as, probiotics and prebiotics
With reference to that can play a part of to promote respective function mutually, there is more positive effect for improving intestinal health；Protein groups
Into improvement, be relatively beneficial to albumen digestion and absorb etc..
The content of the invention
To solve the above problems, the present invention provides a kind of probiotics modulation milk powder and preparation method thereof, and the purpose of realization exists
In, viability problems of the solution probiotics in modulation milk powder, for people provide nutritious, the ox rich in probiotics and oryzanol
Dairy products.Probiotics modulation milk powder of the invention is by cow's milk, inulin, WPC, newborn mineral salt, vegetable oil, Gu Wei
Element and probiotics etc. organically combine a modulation milk powder of exploitation, and the inulin of milk powder addition and probiotics contribute to enteron aisle to be good for
Health, the oryzanol of addition is beneficial to the physical and mental health of human body.
To achieve these goals, technical scheme disclosed by the invention is：A kind of probiotics modulation breast that the present invention is provided
