Description

Contain active Bifidobacterium milk powder and manufacture method thereof
The present invention relates to microorganism culture process and dairy products processing technology.
According to Caucasia, Bulgarian certain areas long lived elder are investigated, the reason that confirms their longevity is that the more lactic acid bacteria than ordinary person is arranged in the enteron aisle.For this reason, the problem of food additives is all made in countries in the world how with these viable bacterias in research from the fifties end beginning.So that under the situation that does not change the flavour of food products quality, improve the health care of food function, keep the breeding balance of enteron aisle flora, play diseases prevention, the effect of curing the disease, safeguard human health longevity.
Bifidobacterium is a kind of leather Lan Shi positive bacteria that colonizes in the enteron aisle, produces organic enzyme in metabolic process, and the effect that suppresses the growth of enteron aisle saprophytic bacteria is arranged.Thereby play anticancerly, strong liver is anti-ly treated constipation, suffers from diarrhoea, and reduces cholesterol, improves vitamin metabolism, improves effects such as immunity function, and health is had multinomial beneficial functional.The Bifidobacterium of survival in human body intestinal canal is a kind of anaerobic bacteria, and its oxygen-resistant ability is different and different with mushroom.For example, bifidobacterium infantis (Bifiaobacteriuminfartrs), bifidobacterium breve (B.breve), bifidobacterium longum (B.Longum) has certain oxytolerant power, and being grown under the low oxygen partial pressure of bifidobacterium adolescentis (B.acblescentis) promptly is suppressed.In addition, the people takes a large amount of antibiolics because of ill need usually.As: erythromycin, spiramvcin, chloramphenicol, they have very big lethality to Bifidobacterium.So, with manual method this class viable bacteria is made food, beverage, constantly human body is replenished, adds, then have very big health nutrient and be worth and social effect.
Bifidobacterium growth condition harshness, its growth temperature are at 37~43 ℃, and growth acidity pH value is 6.5~7.0.Make oral active Bifidobacterium can field planting in enteron aisle, numerous planting, must accomplish 2 points: the one, by stomach the time, do not killed (prove according to the study the normal Bifidobacterium of metabolism has to understand 90% or more be killed) by hydrochloric acid in gastric juice by hydrochloric acid in gastric juice; The 2nd, certain Bifidobacterium amount be arranged, its nutrition health-care functions of competence exertion (is generally 10 5-10 6Individual/more than the milliliter).The Bifidobacterium oral liquid of present city pin, Bifidobacterium food, most because of cultivating condition restriction such as processing, preservation, the survival bacterium is measured not high problem ubiquity.Final products are semi-fluid or liquid in addition, so shortcomings such as transportation inconvenience, viable bacteria storage life weak point are arranged again, do not reach desirable health care purpose.91 years Xinjiang Ya Xi health products milk sheet factories once proposed to make with eight kinds of bacterium such as France, Japan, the Soviet Union method (patent publication No.: CN1059993A) of activiated lactacidase milk tablet, because relate to that bacterial classification is many, manufacturing process and plant machinery degree be low, be not suitable for suitability for industrialized production, and it is also big to the survival rate influence of bacterium to add tablet forming technique.
The objective of the invention is to adopt good bifidobacterium species; according to these bacteria growing condition needs; under anaerobic environment, cultivate breed a certain amount of after; add nourishment protecting agent; and viable bacteria is converted into the live body freeze-dried powder of resting state with freezing, distillation, drying means; mix in proportion with milk powder, packing is made and is contained active Bifidobacterium milk powder again.Take after mixing it with water with warm water when edible, time and term harmonization that the viable bacteria hypopus in the freeze-dried powder is just in time recovered with viable bacteria to time of enteron aisle by stomach, thus reach the purpose that most viable bacterias can field planting in enteron aisle.
Manufacture method of the present invention mainly comprises six technical process and relevant prescription:
One, bacterial classification: the good edible Bifidobacterium of identifying through Institute of Microorganism, Academia Sinica.
Two, medium preparation: 1, the 1200ml fresh milk is carried out degreasing (being about to the milk liquid that fresh milk obtains after centrifugal filtration), moist heat sterilization under 15KPa pressure, the cooling back is standby; 2, in defatted milk, add 1% sterilized glucose, 3% sterilized yellow seriflux, and use NH 3H 2O regulates PH=6.8, and it is standby that cooling is placed on 0-7 ℃ of refrigerator cold-storage.
Three, bacterial classification is handled: main technique is bacterial classification to be placed on carry out inoculated and cultured in the culture medium, till three expansion cultivations reach three-class strain always.Concrete steps are as follows: the test tube that 1, strain inclined plane is inserted fluid nutrient medium is cultivated, and regulates PH=6.8, and 42 ℃ of temperature about 3 hours, promptly get second class inoculum.2, second class inoculum is inserted in the 500ml nutrient solution, transfer 37 ℃ of PH=6.8, temperature, after 16 hours, promptly get three-class strain, it is standby to store in refrigerator.
Four, thalline is cultivated: 1, create anaerobic environment: putting into concentration by the amount of volume 1% in the drier is 15%NaOH and 1 gram pyrogallic acid, and lighted candle produces CO with oxygen 2, form anaerobic environment.2, cultivate the thalline group: the 2000ml nutrient solution is put into the small-sized fermentation jar, and insert three grades of seeds of 5% amount, regulate PH=6.8,37 ℃ of temperature were cultivated 16 hours.3, counting: dilution suitable multiple, microscopic count reach 10 10Individual/milliliter then stops to cultivate, less than 10 10Individual/milliliter, then continue to prolong to cultivate, up to reaching 10 10Till individual/milliliter.
Five, add nourishment protecting agent, freezing, distillation, drying:
1, preparation protective agent: nourishment protecting agent is the hotbed that viable bacteria depends on for existence, and the emulsion that it is made up of glucose, skimmed milk power, cream belongs to protective agent.
