Abstract

The invention discloses milk for regulating the organism immunity. Raw materials of the milk comprise the following ingredients in percentage by weight: 92 to 99 percent of raw material milk, 0.8 to 2.5 percent of fructo-oligose, 0.01 to 0.5 percent of xylo-oligosaccharide, 0.01 to 1 percent of galactooligosaccharide, 0.05 to 3 percent of inulin and organic selenium, wherein the selenium element in the organic selenium accounts for 1.4*10<-5> to 2.8*10<-5> percent of the total weight of the raw materials. The invention also discloses a preparation process of the milk for regulating the organism immunity. The long-short-chain compound prebiotics and organic selenium in a prior mixture ratio are added into the milk, and through the cooperated synergia effect between the substances, the growth and the propagation of the prebiotics in the intestinal tract can be promoted, so the effect of propagating the intestinal mucosal immune cells is realized, in addition, free radicals are favorably cleared, and the milk has the effect of obviously improving the immunity and can be drunk for a long time.

Description

A kind of milk of enhancing body immunity and preparation technology thereof
Technical field
The present invention relates to field of liquid milk, relate in particular to a kind of milk and preparation technology thereof of enhancing body immunity.
Background technology
Along with the fast development of Chinese national economy, fast pace, high efficiency work and life style, and tackle various intense market competition, increasing people is in sub-health state for a long time, causes body immunity to descend.Meanwhile, the rise day by day that the raising of living standards of the people and sustainable development view, quality of life are seen, the health care idea of people's science just progressively forms.The past outdated ideas of " ill just going seen the doctor " are desalinated just gradually, are the fitness mode at center then pursue with the self health care, administer health voluntarily.People thirst for improving self the general level of the health and quality of life through adjustment dietary structure, extra-nutrition material to varying the diet, having higher requirement aspect the nutrition scienceization, the purpose of reach health care, intelligence development, lengthening the life.Take a broad view of this health food quantity in several years; The product number of packages of enhance immunity power is maximum always, but is that the immune milk of primary raw material is less with the liquid milk, and existing product mainly is the liquid dairy product of development of raw materials with the colostrum; Because colostrum output is very limited; Heat endurance is bad, be difficult to collect and large-scale production, so this type has the very difficult large-scale production and selling of colostrum milk of enhance immunity power.
Summary of the invention
Technical problem to be solved by this invention is to overcome that existing immune milk output is little, poor heat stability, the defective that is difficult to large-scale production, and milk of a kind of enhancing body immunity and preparation method thereof is provided.The present invention adds length chain compound " prebiotics " and organic selenium of suitable proportioning in milk; Through the synergistic function between these materials; Can promote beneficial bacterium growth and breeding in the enteron aisle, thereby play the effect of increment intestinal mucosa immunocyte, also help to remove free radical in addition; Make this milk have the effect of significant raising immunocompetence, and can eat for a long time.

The milk of effect embodiment 2 enhancing body immunity of the present invention promotes the effect assessment that calcium, magnesium absorb
1 pilot project
After the mensuration human body is ingested and is tried milk (embodiment 2), the absorptivity of calcium and magnesium.
2 test methods
Choose the age and be 69 ± 2 years old 20 of old men.Before giving given the test agent, the aseptic experimenter's ight soil of taking, the absorptivity of mensuration calcium and magnesium.The experimenter takes and tried milk 2 times every day, each 250mL, continuous 14 days.At the 14th day, the aseptic experimenter's ight soil of taking detected the absorptivity of calcium and magnesium once more.
Ca or Mg absorptivity are calculated by following formula:

3.1 atomic absorption spectroscopy determination picked-up calcium and the content of draining calcium
Accurately take by weighing liquor sample 5.0~10.0g in the 250mL beaker in tall form, add mixed acid digestion liquid 20~30mL, the loam cake surface plate.Place hot digestion in electric hot plate or the electric sand bath.As when good the and acid solution of digestion is very few, add several milliliters of mixed acid digestion liquid again, continue hot digestion, till water white transparency.Add water, heating is to remove unnecessary nitric acid.When treating in the beaker liquid, take off cooling near 2mL~3mL.Wash and shift in 10mL scale test tube with the lanthana solution of 20g/L, add lanthana solution and be settled to scale.
Sample imports in the atomic absorption spectrophotometer after wet method digestion, behind flame atomization, absorbs the resonance line of 422.7nm, and its uptake is directly proportional with content, and is more quantitative with standard series.
3.2 atomic absorption spectroscopy determination picked-up magnesium and the mensuration of draining magnesium:
The digestion method of sample in the digestion method of sample same 3.1.Wash and be transferred in the 10mL scale test tube with the 10mL deionization, add water and be settled to scale.
Sample imports in the atomic absorption spectrophotometer after wet method digestion, behind flame atomization, absorbs the resonance line of 285.2nm, and its uptake is directly proportional with content, and is more quantitative with standard series.
The 4 result of the tests dairy product of the present invention of ingesting is seen table 6 and 7 respectively to the influence of calcium, magnesium absorption rate.
