A kind of preparation method of HERBA DENDROBII sour milk
Technical field
The present invention relates to a kind of preparation method of HERBA DENDROBII sour milk, specifically is to be the method for raw material making sour milk with HERBA DENDROBII and cow's milk.
Background technology
The stem of noble dendrobium is the orchid family herbaceos perennial, and health ministry is classified them as can be used for health food article.Just on the books in Shennong's Herbal, be listed as top grade.Nourishing the stomach to improve the production of body fluid, nourishing Yin and clearing heat, the function that makes eye bright are arranged, be used for the moon and hinder body fluid deficiency, the dry polydipsia, food is few retches, abnormal heat after being ill, order is secretly not clear.Compendium of Material Medica claim it have " reinforcing yin essence benefit essence, thick stomach, mend in spore not enough, make light of one's life by commiting suicide and prolong life " effect.
Sour milk is a fermented dairy product; Have peculiar flavour, sour and sweet palatability, fragrance is good to eat; Nutritious; And have the effect of alleviating lactose intolerance, the biodiasmin in the sour milk also can suppress harmful microbe breeding in the enteron aisle effectively, and is significant to improving whole people's fitness and business economic benefit.
Having with strawberry, aloe in the market is the sour milk that raw material is made, and is that the sour milk that raw material is made does not also appear in the newspapers with the HERBA DENDROBII.
Summary of the invention
The preparation method that the purpose of this invention is to provide a kind of HERBA DENDROBII sour milk, solving HERBA DENDROBII can not be by people as the edible problem of daily bread because of the mouthfeel difference.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of preparation method of HERBA DENDROBII sour milk is characterized in that adopting following steps to make:
A, stem of noble dendrobium preliminary treatment: the bright HERBA DENDROBII that will gather, remove impurity and Lao Ye, clear water is cleaned, and Mechanical Crushing becomes 0.4-0.6 centimetre broken section;
B, preparation stem of noble dendrobium juice: get broken section of HERBA DENDROBII, add the water of 3-5 times of weight portion, be heated to boiling; Kept 3-5 minute, and filtered, get filter residue and add 42-45 ℃ of weight parts water such as grade; The machinery making beating, slurries make stem of noble dendrobium juice with 120-150 purpose filtered through gauze behind the mechanical homogeneous;
C, preparation fermentation stem of noble dendrobium juice: get dry ferment 10-13 weight portion, join in the liquid glucose of 2000 weight portion 5-7% weight concentrations, keep 28-30 ℃; Stir activation in 20 minutes and become yeast juice, be inoculated into by a certain percentage in the stem of noble dendrobium juice, fermentation is 1-8 hour in 28-35 ℃ of environment; After the completion zymotic fluid is heated to 80-90 ℃, kept 10-15 minute, after the cooling; Add pure water and be adjusted to the 7-8% weight ratio, make fermentation stem of noble dendrobium juice;
D, cow's milk preliminary treatment: get fresh cow milk, the solid impurity in mechanical centrifugal removal Ruzhong also kills the part microorganism, adds the white granulated sugar stirring and dissolving of 2-5% weight ratio, and back preheating, homogeneous and sterilization make cow's milk fermentation base;
E, mixing: cow's milk fermentation base, fermentation stem of noble dendrobium juice are mixed by a certain percentage, and mechanical homogeneous makes mixed liquor;
F, inoculation: in gnotobasis, in mixed liquor, add lactobacillus bulgaricus bacterial classification, streptococcus thermophilus strain by a certain percentage, stir;
G, fermentation: postvaccinal mixed liquor is put standing for fermentation in the gnotobasis, fermentation temperature 38-42 ℃, time 4-6 hour;
After H, fermentation were accomplished, aseptic canning was put in the 0-4 ℃ of freezer and is preserved, through dispatching from the factory after the assay was approved.
Step gathers that certain proportion is among the C: yeast juice and stem of noble dendrobium juice weight ratio are 2-5:100.
Step gathers that certain proportion is among the E: cow's milk fermentation base is 7-8:1 with fermentation stem of noble dendrobium juice weight ratio.
Step gathers that certain proportion is among the F: mixed liquor and lactobacillus bulgaricus bacterial classification, streptococcus thermophilus strain weight ratio are: 100:0.002-0.003:0.003-0.005.
It is raw material that the present invention adopts the HERBA DENDROBII can be used for health food, through going flavor, system juice, fermentation, is added in proportion in the cow's milk again, and the inoculation after fermentation makes sour milk, has the effect of nourishing the stomach to improve the production of body fluid, nourishing Yin and clearing heat, the beneficial essence of reinforcing yin essence.Can significantly change the eating mouth feel of HERBA DENDROBII, product is nutritious, and delicate mouthfeel is sour-sweet moderate, can supply people as daily food consumption, for the food application of HERBA DENDROBII provides a new mode.
Below will combine embodiment, the present invention will be carried out comparatively detailed explanation.
The specific embodiment
Embodiment: with 10 kilograms of HERBA DENDROBIIs is example, adopts following steps to make:
1, stem of noble dendrobium preliminary treatment: the bright HERBA DENDROBII that will gather, remove impurity and Lao Ye, clean with flushing with clean water, drop into broken section that is broken into 0.4-0.6 centimetre in the disintegrating machine;
2, preparation stem of noble dendrobium juice: get broken section 10 kilograms of HERBA DENDROBIIs, add 40 kilograms water, be heated to boiling; Kept 4 minutes, and filtered, to remove the peculiar smell of the stem of noble dendrobium; Get filter residue and add 42 ℃ of weight parts waters such as grade, with the beater making beating, slurries filter with 120 purpose sterile gauzes; Drop into homogeneous in the homogeneous, make stem of noble dendrobium juice;
3, preparation fermentation stem of noble dendrobium juice: get dry ferment 5 grams, white granulated sugar 50 grams join in 1 kg of water, keep 30 ℃, stir 20 minutes, and activation becomes yeast juice; Get 1 kilogram of yeast juice, be added in 50 kilograms of stem of noble dendrobium juice, fermentation is 5 hours in 32 ℃ of environment, after the completion zymotic fluid is heated to 80-90 ℃, keeps sterilization in 10-15 minute, after the cooling, adds sterilized water and is diluted to 8%, makes fermentation stem of noble dendrobium juice;
4, cow's milk preliminary treatment: get 400 kilograms of fresh cow milks, the solid impurity in mechanical centrifugal removal Ruzhong also kills the part microorganism, adds 16 kilograms of white granulated sugars, stirring and dissolving, after be preheated to 70 ℃, 40 MPa homogeneous, pasteurize makes cow's milk fermentation base;
5, mix: will get 400 kilograms in cow's milk fermentation base, 50 kilograms of mixing of fermentation stem of noble dendrobium juice, homogeneous makes mixed liquor once more;
6, inoculation: 450 kilograms of mixed liquors, in gnotobasis, add lactobacillus bulgaricus bacterial classification 12 grams, streptococcus thermophilus strain 18 grams, stir;
7, fermentation: with postvaccinal mixed liquor, put standing for fermentation in the gnotobasis, 38 ℃ of fermentation temperatures, 5 hours time;
8, after fermentation was accomplished, aseptic canning was put in the 0-4 ℃ of freezer and is preserved, through dispatching from the factory after the assay was approved.
The above is merely preferred embodiment of the present invention, and all equalizations of being done according to claim scope of the present invention change, and all should belong to the covering scope of claim of the present invention.
