CONTENT
  • Benefit of drinking yoghurt
  • Bifidobacterium
  • Lactobacillus
  • Knowledge of yoghurt

5
The benefit of drinking yoghurt
  • Prevent and cure hypertension
  • Prevent coronary heart disease
  • Prevent osteoporosis
  • Prevent rectum cancer
  • In addition,bifidobacterium in yoghurt can
    enhance human immunity

6
Bifidobacterium
7
Features of bifidobacterium
  • Bifidobacterium is rod-shaped body whose outward
    appearance changes greatfully .
  • The new separated strain generally is even or
    branching, assumes the furcation Y and V, as well
    as stick-shaped or spoon-shaped. The shape may be
    influenced by the nutritional conditions.
  • Gram positive, acid-resistant, no spore, no
    movement.
  • The optimum temperature is 36 38 ?.
  • Forms the smooth micro-colony Usually does not
    form the filiform body.

8
Distributed characteristics
  • The bifidobacterium belongs to the
    actinomycetaceae, widely exist in the intestinal
    tracts of human and many kinds of animals,and
    partly exist in the the human oral cavity and
    vagina.
  • At present it is believed that the
    bifidobacterium does not have the pathogenicity,
    is beneficial to the human.

9
  • The bifidobacterium is one important
    physiological bacteria colony, maintaining the
    human bodys microbiology condition balance.
  • The bifidobacterium begins existing in the
    intestinal tract after born, live in the human
    body all the life.
  • It plays an important role in the childrens
    growth, food digestion and absorption, the
    anganonism ,the immunity.

10
Metabolic characteristics
  • The bifidobacterium can catabolize many kinds of
    sugars such as glucoselactose and produce acid
    to form the acid environment in the intestinal
    tract.
  • The glucose mainly ferments the acetic acid and
    the L () lactic acid, few formic acid and the
    succinic acid and no CO2, no butyric acid ,no
    propionic acid.

11
  • Different bacteria have different metabolic
    ability ,according to this we can identify the
    species.
  • The bifidobacterium has a good ability to
    synthesize the nutrients human body needed, like
    Vitamins biological enzyme, including VB1, B6,
    B12, B2,nicotinic acid and folic acid

12
Biological function
  • Constitute the biology barrier of intestinal
    tract
  • Nutrition
  • Enhance immunity
  • Degrade the toxic materials

13
Bifido-factor
14
Function of bifidofactor
  • Promote proliferation of bifidobacterium
  • Prevent constipation
  • Inhibit pathogen and diarrhea
  • Decrease cholesterol
  • Protect the liver

15
Lactobacillus
16
Lactobacillus
17
Biological features
  • G,bacillus,15µm,usually appear in pair or
    short-chain shaped
  • No spore,no capsule,no motile
  • Facultative anaerobic or anaerobic,ferment
    carbohydrate and produce acids strongly,can
    survive in acid condition

18
Culture feature
  • Grow badly in common medium,grow better if adding
    glucose,lactose,yeast or blood to the medium
  • The colony is very small at 37? for 48h,the
    diameter is only 0.5mm,usually with irregular
    margin or granular surface
  • The optimum PH is 5.5,but still can grow when PH
    is reduced to 3.0 4.0

19
Function of lactobacillus
  • Eliminate poisonous substance
  • Prevent invasion of pathogen
  • Antagonism to common pathogen
  • Promote grastrointestinal peristalsis
  • Synthesis vitamin and AA in intestine
  • Enhance the absorption of Ca ,P,Fe etc

20
Drinks the yogurt
  • Three to want
  • must distinguish the variety
  • must drink about the food latter 2 hours
  • must drink promptly rinses mouth
  • Three not to want
  • do not have to heat up
  • do not want and certain medicines with the
    clothing
  • do not have to give the baby the oral
    administration

21
Who need drink yoghurt?
  • Patients of arteriosclerosis and hypertention
  • Patients of tumor
  • Old and weak patients
  • Persons using antibiotics
  • Osteoporosis patients

22
The technical process
  • fresh milk sweetens
  • -gt the antiseptic -gt temperature decrease
  • -gt vaccination -gt bottling -gt seal
  • -gt constant temperature to ferment
  • -gt cooling -gt to examine the type -gt end product

23
  • Thank you
