preparation example Construction

[0062] The preparation method of lactose-free milk powder comprises the following steps:

[0063] Step 1: The raw milk is subjected to ultrafiltration (UF). Obtain UF retentate containing whey protein, a small amount of lactose, and UF permeate containing lactose, inorganic salts, etc.;

[0064] Step 2: Perform polysulfone composite membrane nanofiltration (PSFNF) on the UF permeate. Obtain the PSFNF retentate containing inorganic salts, lactose, etc., and the PSFNF permeate containing a small amount of lactose and a small amount of inorganic salts;

[0065] Step 3: Perform aromatic polyamide composite membrane nanofiltration (PANF) on the PSFNF permeate. A lactose-containing PANF retentate and a lactose-free PANF permeate were obtained.

[0066] Step 4: The obtained UF retentate was subjected to steps 2 and 3 for 1-3 times to obtain lactose-free PANF permeate. Combine the PANF permeate from step 3 and step 4 to obtain the combined PANF permeate. Samples were taken to det...

[0078] Embodiment 1: Preparation of lactose-free whole milk powder

[0079] Through different pore sizes and different types of membranes, the lactose component in the whole milk is removed by graded filtration. The specific graded filtration operation is as follows:

[0080] (1) Pass pasteurized whole milk (fat content 3.2%) through a tubular ultrafiltration membrane (the material of the tubular ultrafiltration membrane separation layer is polyethersulfone PES, the molecular weight cut-off is 10KDa, and the diameter of the membrane tube is 12mm. The effective membrane area is 2.27㎡). The ultrafiltration operating conditions are: 0.6MPa, feed liquid temperature 35°C, concentration factor 2. Obtain UF permeate and UF retentate, the content of lactose in UF retentate is 3.5%;

[0081] (2) Pass the UF permeate through polysulfone composite membrane nanofiltration (PSFNF), nanofiltration membrane model NF270-400 / 34i (Dow FILMTEC), (nanofiltration membrane separation layer materi...

[0090] Embodiment 2: Preparation of lactose-free skimmed milk powder

[0091] Through different pore sizes and different types of membranes, the lactose component in the whole milk is removed by graded filtration. The specific graded filtration operation is as follows:

[0092] (1) Pass pasteurized skim milk (fat content 0.4%) through a hollow fiber ultrafiltration membrane (the material of the hollow fiber ultrafiltration membrane separation layer is polyvinylidene fluoride PVDF, the nominal filter pore size is 0.08 μm, and the effective membrane area is 10.0㎡), ultrafiltration operating conditions: 0.3MPa, feed liquid temperature 35°C, concentration factor 2. Obtain UF permeate and UF retentate, the content of lactose in UF retentate is 4.4%;

[0093] (2) Pass the UF permeate through polysulfone composite membrane nanofiltration (PSFNF), nanofiltration membrane model HYDRACoRe50-LD-4040 (Hydranautics, the United States), (nanofiltration membrane material sulfonated polyethers...

Abstract

The invention relates to the technical field of dietary nutrition, in particular to a formula of milk powder capable of relieving lactose intolerance for pregnant and lying-in women as well as a preparation method and application of the milk powder. In addition, the invention also relates to application of the formula milk powder in relieving gastrointestinal intolerance symptoms of pregnant women. According to the method, the milk stock solution is subjected to membrane filtration through a fractional step method, lactose molecules are removed, good flavor substances of cow milk are reserved, various trace elements and vitamins suitable for pregnant and lying-in women are added into the milk powder, the milk powder containing various additive elements is obtained, and nutrient elements in the milk powder are kept to the maximum extent; and the milk powder for pregnant and lying-in women keeps the natural raw milk flavor.

Description

technical field [0001] The invention relates to the technical field of dietary nutrition, more specifically, the invention relates to a milk powder formula for alleviating lactose intolerance, a preparation method and application thereof. In addition, it also relates to the use of the formula milk powder in alleviating the symptoms of gastrointestinal intolerance in pregnant women. Background technique [0002] About 70% of the world's population suffers from lactose intolerance, and as high as 90% in Asia. Lactose intolerance generally refers to an impaired ability to digest lactose. Individuals with lactose intolerance lack adequate levels of the enzyme lactase in their digestive system. [0003] Lactose is a disaccharide naturally present in mammalian milk. Secreted by the mammary glands of mammals, it only exists in the animal kingdom. Molecular formula is C 12 h 22 o 11 . Its molecular structure is formed by the condensation of a molecule of glucose and a molecu...
