Abstract
The invention discloses a preparation method of synbiotic goat milk powder, which comprises the following steps: activating probiotics to obtain probiotic mire; adding a compound freeze-drying protective agent; obtaining freeze-drying probiotic powder by freeze-drying; carrying out purification, standardization and reduced pressure condensation on a raw material of goat milk to obtain new raw material of goat milk; adding prebiotics in the condensed raw material of goat milk and then carrying out spray drying to obtain goat milk powder containing the prebiotics; cooling the goat milk powder to room temperature and filtering with a screen; and mixing the screened goat milk powder containing the prebiotics with the probiotic powder under the aseptic condition to obtain the symbiotic goat milk powder. In the invention, the prebiotics are added into condensed degrease goat milk by condensation or whole goat milk and are beneficial to the uniform dispersion of the prebiotics; the probiotics are prepared by a freeze-drying method and added with the freeze-drying protective agent, so that the viable bacteria is more and bacteria has a colony of over 1,010cfu/g; and by adding the prebiotics into the goat milk powder, the prebiotics can be protected and the survival rate of the prebiotics and the functionality of the goat milk powder can be improved.
Description
Technical field
The present invention relates to a kind of preparation method of functional goat milk powder, be specifically related to a kind of preparation method who contains symphysis unit (Synbiotics) goat milk powder of prebiotics (Prebiotics) and probio (Probiotics).
Background technology
Goat Milk is rich in high quality protein matter and aliphatic acid and several mineral materials such as albumin that health is played an important role, globulin, and bad syndrome patient has good health care and therapeutic action to nutrient absorption.Goat milk fat globule little (be merely milk 1/3), and be rich in be beneficial to that body directly utilizes in, the short chain unrighted acid, absorptivity is very high.In addition, abundant calcium constituent can help human body burning fat in the goat milk goods, promotes body to produce the enzyme of degraded fat.Research shows that the goat milk calcium content is higher by 15% than milk, and it is high 5 times to suckle than the people.Goat milk is rich in superoxide dismutase, and normal food has beauty functions, and has antianaphylactic function.The EGF that contains in the goat milk (EGF) when promoting epithelial cell growth, has repair to mucomembranous epithelial cells such as stomach, tracheae and skins; Can urge digestion again can tranquilizing and allaying excitement (because of containing cyclic nucleotide); But and enhancing body immunity, regulate the human body nutrient balance, improve sleep quality; The comfort cushioning characteristic of its meta-alkalescence also has the effect that promotes rehabilitation to diseases such as ephritis, tuberculosis and asthma, is infant, pregnant woman, old man and patient's excellent health products.
Probio (Probiotics) is meant that those are of value to host's microorganism through improving its host's intestinal microecology effect; Probio bacterial classification commonly used has Bifidobacterium (Bifidobateria), Bacillus acidi lactici and some streptococcus; Wherein, Bacillus acidi lactici is commonly used has lactobacillus acidophilus (Lactobicullus acidophilus), Lactobacillus casei (L.casei), lactobacillus bulgaricus (L.bulgaricus) etc.The probio bacterial classification that can be used for health food of China Ministry of Public Health approval at present has: lactobacillus acidophilus, Lactobacillus casei, lactobacillus reuteri, Lactobacillus rhamnosus, bifidobacterium bifidum, bifidobacterium infantis, bifidobacterium breve, bifidobacterium longum, blue and green Bifidobacterium, lactobacillus bulgaricus, streptococcus thermophilus etc.
Prebiotics (Prebiotics) is meant human body indigestion or heavy composition; Alternative growth and the activity that stimulates beneficial bacteria of intestinal tract of these compositions; Thereby the material to the host produces health effect is mainly functional oligose and a small amount of polysaccharide, like oligomeric maltose; Galactooligosaccharide, FOS, isomaltose, milk ketose, xylo-oligosaccharide, stachyose, raffinose, soyabean oligosaccharides, synanthrin etc.
Symphysis unit (synbiotics) is called Synbiotics again; Be to be microecologic regulator of new generation, with probio and prebiotics Combined application, it both can bring into play the physiological bacterial activity of probio; Optionally increase the quantity of probio again; Make probiotic action significantly lasting, resist disease jointly, safeguard the microecological balance of body.
Patent (CN100506055C) has been announced a kind of red date sheep milk powder and preparation method thereof, and the material of interpolation is an integration of drinking and medicinal herbs material red date.Horsepower etc. (horsepower, Han Xuelin, Xu Weirong. old development with goat milk powder. Food Science, 1993 (1): 26-30) reported a kind of old development, in goat milk powder, added vegetable oil, ferrous lactate, vitamin, carbohydrate etc. with goat milk powder.Yan Peifeng (research of probio Freeze Drying Technique and the application in active goat milk powder [D] thereof; Shaanxi Yang Ling: Xibei Univ. of Agricultural & Forest Science & Technology; 2008) reported active probiotic goat milk powder process technology; Through dry pigmentation lactobacillus acidophilus is directly mixed with full-cream goat milk powder, do not relate to prebiotics and add the method in the degreasing goat milk powder to.
Summary of the invention
The object of the present invention is to provide a kind of preparation method who contains the synbiotic goat milk powder of probio and prebiotics simultaneously.
To achieve these goals, the technical scheme that the present invention adopted is:
First: at first with processing probiotics bacterial mud after the probio activation, in probiotics bacterial mud, add the compound freeze drying protectant of identical weight then, in-40 ℃ of pre-freeze 8-12h, move to freeze drier freeze drying 20-24h again and obtain freeze-drying probiotics bacterial powder behind the mixing;
Second: raw material sheep breast after purification and standardization, if the full-cream goat milk powder of preparation symphysis unit directly carried out for the 3rd step, if prepare symphysis unit degreasing goat milk powder, is heated to 36-39 ℃ with raw material sheep breast and carries out degreasing, with fat content control＜0.2%;
The 3rd: the second full-cream sheep breast that obtain of step or degreasing sheep breast reduced pressure to concentrate obtains the sheep breast that solid content reaches 42-50%;
Raw material sheep Ruzhong after concentrating obtains to contain the degreasing goat milk powder or the full-cream goat milk powder of prebiotics through spray-drying after adding prebiotics, and sieves behind the cool to room temperature; Degreasing goat milk powder that contains prebiotics after will sieving again or full-cream goat milk powder mix with the probiotics bacterial powder under 2-6 ℃, aseptic condition and obtain synbiotic goat milk powder;
Or prebiotics mixed under aseptic condition with the probiotics bacterial powder; Cool to room temperature sieves and obtains degreasing goat milk powder or full-cream goat milk powder after raw material sheep after will concentrating the then breast spray-drying, mixed prebiotics and probiotics bacterial powder is directly joined in degreasing goat milk powder or the full-cream goat milk powder process synbiotic goat milk powder;
Said prebiotics addition is by raw material sheep breast 1.5g-6.5g/ liter;
Said probiotics bacterial powder addition is by goat milk powder 1.0-10g/kg.
By the skimmed milk power of 30%-70%, the trehalose of 8%-20%, the glutamic acid of 1%-2%, the glycerine of 1%-2% and the pH of 20-50% are 6.5 citrate buffer solution composition to compound freeze drying protectant of the present invention by mass percentage.
Said probio is that bacterium powder viable count is 1.0 * 10
10-2.0 * 10
