A kind of compound probiotic lactase modulation milk powder
Technical field
The invention belongs to food technology fields, and in particular to a kind of compound probiotic lactase modulation milk powder.
Background technique
Lactose is primarily present in milk and its product, needs to absorb by lactase breaks down.Alactasia meeting
Cause lactose digestion malabsorption, some patientss will appear abdominal distension, abdominal pain, a series of clinical symptoms based on diarrhea, referred to as newborn
Sugar does not tolerate.Alactasia accounts for 15% in Nordics, and Black people and people from Latin America account for 80%, and American Indians and Asian
Up to 100%.Some researches show that, in 3-5 years old, the 7-8 years old and 11-13 years old group children in China, alactasia and lactose intolerance
The incidence received is respectively 38.5%, 87.0%, 87.0% and 12.2%, 32.2%, 29.0%.Lactose intolerance not only influences
, there are malaise symptoms in the absorption of lactose in milk and its product, and protein, calcium, iron etc. in milk and other foods can also sought
That supports element is absorbed and utilized reduction, causes malnutrition.
Probiotics is a kind of active microorganism beneficial to host, is to be colonized in human body intestinal canal, in reproductive system, can generate
Definite health efficacy so as to improve host's microecological balance, play the active beneficial microorganism general name of beneficial effect.Human body moves
Beneficial bacterium or fungi mainly have in object: clostridium butyricum, lactobacillus, Bifidobacterium, actinomyces, saccharomycete etc..Generation at present
The most powerful product of the function of being studied in boundary be mainly the above all kinds of microorganism groups at composite reactive probiotics, be widely applied
In bioengineering, industrial or agricultural, food safety and life and health field.The file that planning commission issues over the years is defended according to country, is arrived
So far, the strain one that can be used for infant food shares 7, and the maximum probiotics supplier in the whole world has two, is respectively
U.S.'s Danisco and section of Denmark Hansen.The representative strain that the former supplies is Bi-07, NCFM and HOWARV series probiotics
(HN001,HN019);The representative strain of the latter's supply is Bb-12 and LGG.
Lactose excessive in human body can be resolved into glucose and galactolipin by lactase.Glucose is partes corporis humani point metabolism
Energy source, it is necessity of infant brain development that galactolipin, which is then required structure sugar when National People's Congress's brain and mucous membrane tissue are metabolized,
Tissue, has close ties with shooting up for infant brain.Furthermore lactase can also be generated in human body by transglucosidation
Oligosaccharide, these oligosaccharide are a kind of low molecular weights, and not sticky water-soluble dietary fiber, it is used as proliferation factor in enteron aisle
It is only utilized by Bifidobacterium, is utilized without by putrefactivebacteria, can so greatly reduce the generation of harmful intestinal tract toxin, to prevention
Constipation and diarrhea play a very important role.Industrially lactase is produced using microbe fermentation method.The cream in different microorganisms source
The pH nature difference of carbohydrase is larger, is generally divided into neutral lactase and acid lactase.It is produced by Escherichia coli (E.Coli)
Lactase pH is 7.0~7.5;It is 6.0~7.0 by the saccharomycete person of being made;It is 5.0 or so by the mould person of being made.It is mended by external source
The case where filling the mode of lactase, can effectively solving lactose intolerance when intake dairy produce.
Patent document CN201410400017.6 discloses a kind of probiotics baby milk powder, the probiotics baby milk powder
Include lactose, vegetable oil, desalted whey powder, skimmed milk power, concentrated whey protein powder, complex prebiotics, mineral substance premix, flower
Raw tetraenoic acid Ultramicro-powder, docosahexaenoic acid Ultramicro-powder, vitamin premix, compound probiotic freeze-dried powder, lactoferrin, L-
The ingredients such as carnitine, taurine part and nucleotide, the milk powder can adjust infant's intestinal flora balance, promote enteron aisle it is unobstructed, suppression
Diarrhea processed and the immunity for improving infant, but wherein main component is lactose, is unable to satisfy the infant of lactose intolerance
Group.
Separately there is patent document CN201610170068.3 to disclose a kind of lactose-free baby formula milk powder and its preparation side
Method, the lactose-free baby formula milk powder contain vegetable fatty powder, Evamilk albumen and sepg whey albumen, although should
Lactose-free formula section directly avoids the generation of lactose intolerance in composition, but lactose be nutrition important in baby's growth and development at
Point, long-term lacking is also unfavorable for the growth and development of baby, the problem of can not fundamentally changing lactose intolerance.
We have found that probiotic supplemented can help to improve intestinal health, more conducively baby couple supplementing lactase simultaneously
Nutritional ingredient is absorbed and utilized, and achievees the effect that 1+1 is greater than 2, but product currently on the market or be a probiotic supplemented
And it is free of lactase or is only to add single probiotics or added probiotics is to make in infant food
, and also supported without enough science on additive amount.Furthermore lactase and probiotics are all active materials, steady
It is qualitative especially important, need formula, in terms of its stability is adequately investigated.
Summary of the invention
