specific Embodiment approach 1

[0031] Specific embodiment one: the storage-resistant MPC powder of this embodiment, it is by mass percentage by the protein of 40%~90%, the lactose of 0.5%~45%, the fat of 0.5%~2%, the moisture of 3%~5%, 5.5%-8% ash and 0.05%-1% surfactant; wherein the surfactant is calcium stearoyl lactylate, lecithin or sucrose fatty acid ester.

specific Embodiment approach 2

[0032] Specific embodiment two: the difference between this embodiment and specific embodiment one is that the storage-resistant MPC powder is composed of 63.5% protein, 25% lactose, 1% fat, 4% moisture, 6% Composed of ash and 0.5% surfactant. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0033] Specific embodiment three: the preparation method of the storage-resistant MPC powder of this embodiment is realized according to the following steps:

[0034] 1. Milk sample processing: Centrifuge fresh milk at 5000-10000 rpm for 15-30 minutes to remove fat and obtain skim milk;

[0035] 2. Sterilization treatment: skim milk is pasteurized at low temperature for a long time; or it is pasteurized at high temperature for a short time; or it is sterilized by a 0.1 μm microfiltration membrane; or it is pasteurized and then 0.1 μm microfiltration Membrane sterilization;

[0036] 3. Removal of lactose and some minerals: After sterilization, use a 3KD ultrafiltration membrane for ultrafiltration or a 3.5KD dialysis membrane for dialysis. During the treatment process, water needs to be added and the continuity of operation should be maintained;

[0037] 4. Concentration: After removing lactose and some minerals, carry out evaporation concentration or nanofiltration concentrat...

Abstract

The invention discloses storable MPC (Milk Protein Concentrate) powder and a preparation method thereof, relating to MPC powder and a preparation method thereof, and solving the problems that the water solubility of existing MPC powder is reduced after the existing MPC powder is stored and an improving method researched for the existing MPC powder commonly has difficulty in industrialized production. A method 1 comprises the following steps: 1, processing a cow milk sample; 2, sterilizing; 3, removing lactose and partial minerals; 4, concentrating; 5, mixing; and 6, drying. A method 2 comprises the following steps: 1, processing a cow milk sample; 2, sterilizing; 3, removing lactose and partial minerals; 4, concentrating; 5, drying; and 6, mixing. According to the storable MPC powder, by adding different types of surfactants, the trend of polymerization of protein molecules is weakened, the emulsion stability of a system is improved, and the probability of particle enlargement and water solubility characteristic reduction caused by fat precipitation is lowered. The preparation method disclosed by the invention is simple in operation, low in cost, large in capacity, and capable of realizing industrialized production; conventional equipment is adopted in the preparation method.

Description

technical field [0001] The invention relates to MPC powder and a preparation method thereof. Background technique [0002] Milk has high nutritional value and excellent therapeutic and health effects. Milk protein concentrate powder (Milk protein concentrate, MPC) refers to the powdery substance obtained by removing most of the lactose and minerals from skim milk through membrane separation technology, and then spray drying. The protein content of commercially available MPC is usually 40 %-85%. MPC retains almost all the protein in milk, and also retains the natural ratio of casein to whey protein, so it has good nutritional function and development prospects. MPC has a light milk aroma, fresh creamy taste and rich nutritional value. It is often used as an ingredient to add to beverages, yogurt, cheese, meat products, baked goods, and ice cream to improve the flavor of food and increase nutritional value. , and these foods require MPC to have good water solubility, but st...
