Description

A kind of preparation method of degreasing Yoghourt
Technical field
The invention belongs to food dairy products field more particularly to a kind of preparation methods of degreasing Yoghourt.
Background technology
In recent years, the concern of health is also being improved due to people.For generation and the treatment mammitis etc. for preventing disease Disease, culturist can add the feed addictive containing certain proportion antibiotic in ox feed and in drinking water, if long-term drink With the milk containing antibiotic, the antibiotic in milk can enter human body by food chain, be undoubtedly equal to and take small dose for a long time The antibiotic of amount, especially for infant and children population, is reduced once illness is difficult again to prove effective with antibiosis extract for treating of the same race Inessential antibiotic intake is very necessary.
Meanwhile minding that the consumer of foodstuff calories increases, demand " low fat ", " degreasing ", " low in calories " in Yoghurt Market The demands of commodity also expanding, degreasing Yoghourt is because by more and more the advantages of its low in calories, low fat, low cholesterol The condition subjects such as the welcome of people, especially hyperlipidemia or artery sclerosis and the crowd for needing to control energy intake.Drink degreasing Yoghourt can not only supplement protein and probiotics, but also can control the intake of metabolism of lipid and cholesterol.But it much declares to take off on the market The product fat content of resin acid milk can not preserve other very well still above 0.5% or more in the preparation process of degreasing Yoghourt Nutritional ingredient is caused and is greatly wasted.
Invention content
More than in view of the deficiencies of the prior art, it is an object of the present invention to provide a kind of preparation methods of degreasing Yoghourt to solve Problem.
To achieve the above object, the technical solution adopted by the present invention is that:A kind of preparation method of degreasing Yoghourt, feature exist In including the following steps:The acquisition of milk supply, the detection of antibiotic, degreasing sterilization, fermentation and mounted box;
The acquisition of S1, milk;
1) cow is carried out to adopt milk using adopting milk device, it is cup-shaped to adopt milk device, a diameter of 20-30mm, length 8- 100mm;
2) milk device is adopted to be made of silicone;
3) when adopting milk device and being sleeved on nipple, when milking, which adopts milk work and rhythmically squeezes, adopts milk device, is alternately produced extruding, sucks Two states;
4) when in suck state when, it is in vacuum state, vacuum pressure value 0.05Mpa, expression frequency to adopt inside milk device It is 100-150 beats/min;
The detection of S2, antibiotic;
1) sample bacterium is positioned in fluid nutrient medium, sample bacterium is streptococcus thermophilus;
2) mass component of fluid nutrient medium is:Beef extract mass fraction is 1%, and magnesium sulfate mass fraction is 0.03%, Qualities of glycerin score is 2%, and lactose mass fraction is 0.5%, and agar mass fraction is 2%, remaining is distilled water;
3) it will be added to the fluid nutrient medium of sample bacterium, be placed in 36~37 DEG C of incubators and cultivate 15 hours, for use;
4) it takes and adopts the collected milk 10mL of milk device, in 80 DEG C of heating water baths 5 minutes, be cooled to 36~37 DEG C, be loaded bacterium Liquid 1mL, in 40~50 DEG C of water-baths 1 hour, gained mixed liquor was placed in 36~37 DEG C by the TTC indicator 0.3mL that 2-5% is added In environment, cultivate 30 minutes;
If 5) mixed liquor color is constant, it is not up to standard to adopt the anti-body element index of the collected milk of milk device;It is adopted if taking on a red color The anti-body element index of the collected milk of milk device is not up to standard;
6) take milk up to standard as raw material;
S3, degreasing sterilization;
1) by milk water-bath up to standard 1~2 hour, bath temperature is controlled at 70~80 DEG C, is cooled to 36~37 DEG C, Remove the skin on boiled milk that milk up to standard is precipitated;
2) processing method of the step 1) in repetition step S3 3~4 times;
3) milk of the step 2) in step S3 is positioned over after cream-milk separator carries out missible oil separation, it is placed in 600~ It is handled 30~50 minutes under the conditions of 700Mpa;
S4, fermentation;
The Yoghourt that will be obtained after step S4 processing, after being cooled to 40~45 DEG C, is added leavening, stirs 10~20 minutes After stop, fermentation temperature is maintained at 40~45 DEG C, ferments 4~5 hours;
The quality of the leavening of addition is the 5~8% of the Yoghourt quality obtained after step S4 is handled;
Leavening is made of Bifidobacterium, lactobacillus bulgaricus, lactobacillus acidophilus and Lactobacillus casei, and mass ratio is 1:3:1:1;
S5, mounted box;
The Yoghourt that will be obtained after step S4 processing, after being cooled to 18~20 DEG C, the mounted box in gnotobasis.
Beneficial effects of the present invention are:A kind of preparation method of reliable efficient degreasing Yoghourt is provided, made from this method Degreasing Yoghourt fat content is low, and antibiotic content is small, is suitable for the sufferers such as hyperlipidemia or artery sclerosis and children and teenager group Body.
Specific implementation mode
The embodiment of the present invention is illustrated below, it should be understood that preferred embodiment described herein is only used for The bright and explanation present invention, is not intended to limit the present invention.
A kind of preparation method of degreasing Yoghourt, which is characterized in that include the following steps:The acquisition of Yoghourt, the inspection of antibiotic Survey, degreasing sterilization and mounted box;
The acquisition of S1, Yoghourt:Cow is carried out to adopt milk with milk device is adopted, it is cup-shaped to adopt milk device, a diameter of 20-30mm, long Degree is 8-100mm;Milk device is adopted to be made of silicone;When adopting milk device and being sleeved on nipple, when milking, which adopts milk work and rhythmically squeezes, adopts Milk device, is alternately produced that extruding, suck two states;When in suck state when, it is in vacuum state, vacuum pressure to adopt inside milk device Value is 0.05Mpa, and expression frequency is 100-150 beats/min;
The detection of S2, antibiotic:Sample bacterium is positioned in fluid nutrient medium, sample bacterium is streptococcus thermophilus;Fluid nutrient medium Mass component be:Beef extract mass fraction is 1%, and magnesium sulfate mass fraction is 0.03%, and qualities of glycerin score is 2%, breast Sugared mass fraction is 0.5%, and agar mass fraction is 2%, remaining is distilled water;It will be added to the fluid nutrient medium of sample bacterium, set It is cultivated 15 hours in 36~37 DEG C of incubators;It takes and adopts the collected Yoghourt 10mL of milk device, it is cold in 80 DEG C of heating water baths 5 minutes But to 36~37 DEG C, it is loaded bacterium solution 1mL, in 40~50 DEG C of water-baths 1 hour, the TTC indicator 0.3mL of 2-5% are added, by gained Mixed liquor is placed in 36~37 DEG C of environment, is cultivated 30 minutes;If mixed liquor color is constant, it is anti-to adopt the collected Yoghourt of milk device Body element index is not up to standard;It is not up to standard that the anti-body element index of the collected Yoghourt of milk device is adopted if taking on a red color;Take Yoghourt conduct up to standard Raw material;
S3, degreasing sterilization:By Yoghourt water-bath up to standard 1~2 hour, bath temperature was controlled at 70~80 DEG C, is cooled to 36~37 DEG C, remove the skin on boiled milk that Yoghourt up to standard is precipitated, reprocessing method 3~4 times;By Yoghourt be positioned over cream-milk separator into After the separation of row missible oil, it is placed under the conditions of 600~700Mpa and handles 30~50 minutes;
S4, fermentation;After being cooled to 40~45 DEG C, leavening is added in the Yoghourt that will be obtained after step S4 processing, and stirring 10~ Stop after twenty minutes, fermentation temperature is maintained at 40~45 DEG C, ferments 4~5 hours;The quality of the leavening of addition is at step S4 The 5~8% of the Yoghourt quality obtained after reason;Leavening is by Bifidobacterium, lactobacillus bulgaricus, lactobacillus acidophilus and cheese Lactobacillus forms, mass ratio 1:3:1:1;
