Problems solved by technology

[0004] The prior art discloses several low-lactose milk powder processes, such as a jujube-type low-lactose milk powder and its preparation method (Chinese patent authorization announcement number CN102429030B). The lactose hydrolysis process in this patent uses a low-temperature hydrolysis lactose process (the hydrolysis temperature is preferably 6°C ), resulting in long hydrolysis time (15-18h hydrolysis time), which is not conducive to the turnover of production equipment
Such as the preparation method of sugar-free milk powder (Chinese patent authorization announcement number CN101426375B), this patent uses methods such as enzyme curd separation, emulsi...

Embodiment 1

[0016] (1) Acceptance of raw milk: refer to the physical and chemical indicators and microbial indicators of the national standard GB19301 to check and accept raw milk (physical and chemical indicators: fat ≥ 3.1%, protein ≥ 2.8%, acidity: 12-18 。 T; microbial index: the total number of colonies ≤ 2 million / cfu);

[0017] (2) Separation and cleaning of milk: use 80 and 200 mesh filters to filter the raw milk twice, remove impurities through the separator, and standardize the milk;

[0018] (3) Pre-sterilization: Pre-sterilize the standardized milk (80°C, 15S) and store it below 6°C;

[0019] (4) Initial batching: heat up the milk in (3), add whole milk powder, polydextrose and other raw materials for initial batching;

[0020] (5) Secondary ingredients: check the physical and chemical indicators of the completed primary ingredients, and adjust again through water replenishment and constant volume operation to reduce the material indicators to the required physical and chemica...

Abstract

The title of the invention is low-lactose milk powder and a preparation method thereof. The invention discloses low-lactose milk powder, which contains (by weight): 22-25% of fat, 20-23% of protein and 5.5% and below of lactose. The invention discloses a preparation method of the low-lactose milk powder, comprising the following steps: (1) acceptance inspection of raw milk; (2) separation for milk purification; (3) pre-sterilization; (4) primary burdening; (5) secondary burdening; (6) homogenizing and pre-sterilization; (7) lactase enzymolysis; (8) enzyme deactivation treatment; (9) milk heating-up and preheat sterilization; (10) evaporation and concentration; (11) high pressure atomizing; (12) drying and fluidized bed redrying; (13) powder discharge and powder screening; and (14) packaging. By controlling physical and chemical indexes of a material before hydrolysis and by the utilization of a high-temperature lactose enzyme hydrolysis technology, the low-lactose milk powder is produced, and lactose hydrolysis rate reaches 80% and above.

Description

technical field [0001] The invention relates to the technical field of dairy product production and processing, in particular to a processing method for making low-lactose milk powder with cow's milk as the main raw material. Background technique [0002] Milk is the most perfect food that humans can obtain from nature so far. Milk is rich in minerals, such as calcium, phosphorus, iron, zinc, etc. The most rare thing is that milk is the best source of calcium for the human body. And the ratio of calcium and phosphorus is appropriate, which is conducive to the absorption of calcium. Lactose is a disaccharide composed of two monosaccharide molecules. The average content of lactose in fresh milk is 4.8%. After lactose enters the gastrointestinal tract, it cannot be directly absorbed. It needs lactase to decompose it into monosaccharides before it can be absorbed by the human body. use. People produce enough lactase during breastfeeding, but many people gradually reduce the pr...
