Abstract
The present invention provides a preparation method of infant formula milk base powder. Raw milk in line with the national standards of food safety is used as a raw material, impurities are removed through a milk clarifier, then the impurity removed raw milk is homogenized at 15-20 MPa, the raw milk is subjected to nozzle spraying at a pressure of 50 MPa, at the same time, directly sprayed steam is introduced at a steam pressure of 0.3-0.5 MPa and at a steam temperature of 142.9 DEG C-158.1 DEG C, mixing time is 3-5 seconds, then a part of water in the materials is evaporated in a flash tank under the function of negative pressure, the temperature of the materials is lowered to 70 DEG C or below within 5 seconds, the cooled materials are spray-dried, and the spray-dried materials are subjected to nitrogen packaging to obtain the finished products. The prepared infant formula milk base powder by the technology maintains most nutrients in the raw milk, and the index of microorganisms in the finished products is lower than that of the relevant national standards.
Description
Technical field
The present invention relates to a kind of preparation method of infant formula original washing powder, and in particular to prepared using direct-injection steam sterilizing
The method of infant formula original washing powder.
Background technology
On market, infant formula species is various, and there are tens even up to a hundred kinds in each manufacturing enterprise, with
Constantly improve of the country to dispensed food for baby legal norm, for ensuring food safety, country proposes higher to manufacturing enterprise
The requirement of condition, product perform standard and also rise to certain altitude.Infant formula is with milk powder or lactogenesis as raw material, by not
Demand is grown with age bracket infant, a kind of baby formula for adding food enrichment according to the pertinent regulations of state and preparing
Food.So milk powder or the indices of lactogenesis, especially microbiological indicator are put forward higher requirement, raw milk or milk powder
Once microorganism is exceeded, it is unqualified to directly result in kind of product, not only brings massive losses to manufacturing enterprise, and to infant's
It is healthy to bring greatly negative effect, the food-safety problem being related in this respect to emerge in an endless stream.
The content of the invention
Based on above weak point, the present invention provides a kind of preparation method of infant formula original washing powder, and this method is adopted
High temperature direct injection steam to liquid milk instantaneous sterilization and then rapid cooling, i.e., ensure that to greatest extent in material nutriment not by
Destruction, can all kill microorganism in material again, provide good original washing powder for infant formula.
The object of the present invention is achieved like this：A kind of preparation method of infant formula original washing powder, by food security state
The lactogenesis of family's standard goes the removal of impurity through milk clarifier；Then in 15-20MPa homogeneous；It is characterized in：Again with direct-injection steam mist
Change：By lactogenesis under 50MPa pressure, by nozzle atomization, direct-injection steam is at the same time passed through, steam pressure is 0.3-
0.5MPa, 142.9 DEG C -158.1 DEG C of vapor (steam) temperature, immixture time are the 3-5 seconds；Flash concentration：This process is in flash tank
Carry out, material evaporates portion of water under suction function, and in 5 seconds, temperature of charge is down to less than 70 DEG C；Then it is spray-dried：
150 DEG C 160 DEG C of EAT, 90 DEG C 95 DEG C of leaving air temp；Last nitrogen-filled packaging.
The infant formula original washing powder of Jing this technique preparations, remains the nutrient content in most of raw milk, in finished product
Microorganism is less than concerned countries standard.
Specific embodiment
It is for a more detailed description to the present invention with reference to specific embodiment：
Embodiment 1：
Lactogenesis → net breast → homogeneous → with direct-injection steam atomization → flash concentration → spray drying → nitrogen-filled packaging →
Finished product
Analytic process
Lactogenesis：GB 19301-2010 should be met《National food safety standard lactogenesis》Requirement；
Net breast：Lactogenesis goes the removal of impurity through milk clarifier；
Homogeneous：15MPa homogeneous；
It is atomized with direct-injection steam：This process adopts high-pressure atomization, by lactogenesis under 50MPa pressure, by nozzle mist
Change, be at the same time passed through direct-injection steam, steam pressure is 0.3MPa, and 142.9 DEG C of vapor (steam) temperature, immixture time are 3 seconds；
Flash concentration：This process is carried out in flash tank, and material evaporates portion of water under suction function, in 5 seconds
Temperature of charge is down to less than 70 DEG C；
It is spray-dried：150 DEG C of EAT, 90 DEG C of leaving air temp
Nitrogen-filled packaging：Nitrogen is adopted for medium, packaging can become finished product.
Embodiment 2：
Lactogenesis → net breast → homogeneous → with direct-injection steam atomization → flash concentration → spray drying → nitrogen-filled packaging →
Finished product
Analytic process
Lactogenesis：GB 19301-2010 should be met《National food safety standard lactogenesis》Requirement；
Net breast：Lactogenesis goes the removal of impurity through milk clarifier；
Homogeneous：20MPa homogeneous；
It is atomized with direct-injection steam：This process adopts high-pressure atomization, by lactogenesis under 50MPa pressure, by nozzle mist
Change, be at the same time passed through direct-injection steam, steam pressure is 0.5MPa, and 158.1 DEG C of vapor (steam) temperature, immixture time are 5 seconds；
Flash concentration：This process is carried out in flash tank, and material evaporates portion of water under suction function, in 5 seconds
Temperature of charge is down to less than 70 DEG C；
It is spray-dried：160 DEG C of EAT, 95 DEG C of leaving air temp
Nitrogen-filled packaging：Nitrogen is adopted for medium, packaging can become finished product.
Product prepared by this method the results are shown in Table 1 with concerned countries standard microorganism Indexes Comparison
1 microbiological indicator of table compares
This handicraft product microbiological indicator is required well below national standard index of correlation, is eaten safer.
