Abstract
The invention discloses a freeze-drying and fresh-keeping preparation method of milk products for babies, comprising the following steps of: purifying selected fresh raw milk, separating and sterilizing; carrying out vacuum cooling treatment on the purified raw milk to reduce the temperature to 5-0 DEG C; quickly freezing raw materials to the temperature ranging from 30 DEG C below zero to 60 DEG C below zero; smashing the processed raw materials under the condition that the temperature ranges from 30 DEG C below zero to 60 DEG C below zero; carrying out pelleting treatment: screening and separating the processed raw material under the condition that the temperature ranges from 30 DEG C below zero to 60 DEG C below zero until ice crystals same as rice grains in shape and size are made; then, feeding the processed raw materials into a drying machine to dehydrate to reduce the water content to below 5%, wherein the vacuum degree of a drying chamber is 0.8-1.2MMHG, the temperature of a common heating plate is 90-40 DEG C, the central temperature of the processed raw materials ranges from 30 DEG C below zero to 60 DEG C below zero, and the freeze-drying time is 20-40 h; and carrying out packaging treatment. The freeze-drying milk powder prepared by using the method provided by the invention contains no any pigment or additives, and the nutritional ingredients of the raw milk are not lost or damaged, and therefore, a green health care food for babies, which has various trace elements and mineral substances in the raw milk and natural flavor, is provided.
Description
Invention field
The present invention relates to a kind of food, refer in particular to the freeze dried and antistaled preparation method of a kind of baby milk goods.
Background technology
Dairy product is that modal breast milk substitutes or supplement.In the dairy produce of China was produced, the production of milk powder accounted for about 80% of whole dairy produce total output, because milk powder is convenient to store and transportation.
The technology of existing production milk powder adopts the concentrated spray seasoning mostly.Its production technology Main Problems is: because the temperature control of the critical process processes such as sterilization, concentrated, spray-drying is higher, therefore the loss of its nutritional labeling is larger, particularly a large amount of losses of the nutritional labelings such as the destructive rates such as the trace element in Ruzhong, mineral matter＞60%, active material and affected the natural quality of milk powder.In addition, the milk powder solubility of preparation, brew are relatively relatively poor.
Technology contents
The object of the invention is to overcome the deficiency in the background technology and provide a kind of baby milk goods freeze dried and antistaled preparation method.Adopt the freeze-dried milk powder of the present invention's preparation, do not contain any additive, former newborn nutritional labeling is not subject to any loss and destruction, is pure natural, the milk powder with former newborn various trace elements, mineral matter of a kind of original flavor.
The technical scheme of invention is:
The freeze dried and antistaled preparation method of a kind of baby milk goods, it is characterized in that: it comprises:
A, the fresh former breast of selected usefulness carry out former breast purification, separation and sterilization; Cold storage: the former breast after will purifying carries out vacuum cool-down to be processed, and makes temperature be down to 5 ° of C～0 ° C;
B, carry out fast frozen: raw material is carried out quick-frozen, and its temperature is :-30 ° of C～-60 ° C, do not run off to guarantee original trace element and nutrient;
C, smash processing: in temperature be: under-30 ° of C～-60 ° C conditions, will process raw material and smash;
D, carry out granulation and process: in temperature be: under-30 ° of C～-60 ° C conditions, will process raw material and screen, separate, until make the ice crystal of shape such as grain of rice size; The containers for future use of packing into;
E, carry out cryogenic freezing and dehydrate: will process raw material to send in the drying machine and dewater, moisture is down to below 5%, the vacuum of hothouse is: 0.8-1.2MMHG; The temperature of general heating plate is: 90 ° of C-40 ° of C, and the central temperature that processes raw material is :-30 ° of C～-60 ° C; Freeze-drying time is: 20-40 hour;
F, will be prepared into granular finished product and pack processing, carry out sealed barrier package by demand: comprise bottled or aluminium-foil paper packed.
Wherein, described quick freezing temperature is preferably :-55 ° of C.
Described freeze-drying time is preferably: 35 hours.
Described drying means also can adopt common drying or vacuum drying method.
The invention has the advantages that: the freeze-dried milk powder that adopts the present invention's preparation, do not contain any pigment and any additive, former newborn nutritional labeling is not subject to any loss and destruction, is a kind of baby's green health food with former newborn various trace elements, mineral matter, genuineness.Because product of the present invention produces under low temperature and vacuum condition, thus this food do not refrigerate, as long as after packing, just at normal temperatures long term storage, transportation and sale.Under the state of sealing, can preserve 2-3 and never degenerate.Product of the present invention meets the development trend of World of Food industry " green, convenient, health ", and market and domestic market have good prospect abroad.
