Problems solved by technology

[0007] At present, there is no formula for infants with lactose intolerance in China, and there are only a few imported lactose-free/low-lactose infant formulas on the market. As a result, the variety of lactose-free infant formula entering the Chinese market is scarce and restricted by sales channels. Many parents of babies with special medical conditions find it difficult to buy such products, and it is really hard to find a "fan"
[0008] Using the traditional preparation method, lactose is completely replaced by other...

preparation example Construction

[0047] The invention provides a method for preparing lactose-free infant formula, comprising the following steps:

[0048] A) preparation of vegetable fat powder:

[0049] Dissolving glucose syrup and casein in water to obtain a mixed aqueous solution;

[0050] Dissolving mono-diglyceride fatty acid esters in refined vegetable oil to obtain a mixed oil solution;

[0051] After mixing the mixed aqueous solution and the mixed oil solution, adding a mixed solution of sodium dihydrogen phosphate, sodium citrate and potassium citrate for mixing and emulsification to obtain an emulsion;

[0052] The emulsion is homogenized, sterilized and spray-dried to obtain vegetable fat powder;

[0053] B) Preparation of lactose-free whole milk powder:

[0054] Ultrafiltering the raw milk to obtain a filtrate;

[0055] mixing the filtrate with lactase and performing enzymolysis to obtain an enzymolysis solution;

[0056] Spray-drying the enzymatic hydrolyzate after sterilizing it to obtain ...

Embodiment 1

[0117] 1) Mixing of ingredients: first dissolve 480 kg of glucose syrup and 53 kg of casein with warm water at about 55°C in a certain proportion, then add 28 kg of mono-diglyceride fatty acid esters to 430 kg of refined vegetable oil, then mix the two, and finally Add 3.5 kg of sodium dihydrogen phosphate, 2.2 kg of sodium citrate, and 3.3 kg of potassium citrate (add after dissolving and diluting with water), adjust the concentration of the mixture to about 50%, and emulsify at high speed for 15 minutes.

[0118]2) Preheating and homogenization: Preheat the emulsified material to a temperature suitable for homogenization of 70°C, and then perform homogenization with a homogenization pressure of 35MPa.

[0119] 3) Sterilization: Sterilization temperature 95°C, 24 seconds;

[0120] 4) Spray drying: when spraying, the temperature of the concentrated milk is kept at about 52°C, the vacuum degree of the spray chamber is kept at about 200Pa, the nozzle aperture is 1.25mm, the inle...

Embodiment 2

[0122] 1) Ingredients mixing: first dissolve 460 kg of glucose syrup and 58 kg of casein in warm water at about 60°C in a certain proportion, then add 23 kg of mono-diglyceride fatty acid esters to 450 kg of refined vegetable oil, then mix the two, and finally Add 3.6 kg of sodium dihydrogen phosphate, 2.2 kg of sodium citrate, and 3.2 kg of potassium citrate (add after dissolving and diluting with water), adjust the concentration of the mixture to about 48%, and emulsify at high speed for 15 minutes.

[0123] 2) Preheating and homogenization: Preheat the emulsified material to a temperature suitable for homogenization of 68°C, and then perform homogenization with a homogenization pressure of 33MPa.

[0124] 3) Sterilization: Sterilization temperature 96°C, 24 seconds;

[0125] 4) Spray drying: when spraying, the temperature of the concentrated milk is kept at about 53°C, the vacuum degree of the spray chamber is kept at about 190Pa, the nozzle aperture is 1.30mm, the inlet ai...

Abstract

The invention provides a lactose-free infant formula food and a preparation method thereof. The preparation method disclosed by the invention comprises the following steps: adopting a dry-wet compounding process, namely producing vegetable fat powder by a wet process, and producing lactose-free whole milk powder by a lactose digestion process; performing dry mixing on the vegetable fat powder, thelactose-free whole milk powder, other main ingredients and auxiliary materials and bioactive substances, thereby obtaining the formula food suitable for lactose intolerant infants at an age of 0-12 months. According to the formula, the lactose is completely replaced with other carbohydrates, the lactose content of the product is less than 0.5wt%, and 1.8-2.2wt% of galactose having an important effect on brain development of the infants is remained. The protein in the formula is provided by lactoprotein, and the formula food is suitable to be eaten by the lactose intolerant infants so as to avoid lactose intolerance.

Description

technical field [0001] The invention belongs to the technical field of food for infants and young children, and in particular relates to a lactose-free formula food for infants and a preparation method thereof. Background technique [0002] The population of infants and young children aged 0 to 3 in my country is 70 million, and about 17 million newborn babies are born every year. The huge consumer groups have created a huge market space for infant milk powder in China. However, infants who mainly eat formula milk powder are lactose intolerant. Infected, seriously affected the normal growth and development of infants and young children. [0003] Lactose intolerance is due to the lack of congenital lactase or other pathological reasons, the activity of lactase is reduced, lactose cannot be decomposed into glucose and galactose, undigested lactose enters the colon with the digestive tract, and is fermented by bacteria to produce short Chain fatty acids such as acetic acid, pro...
