Process for producing powdered milk comprising multiple resistance nutrition immune optimization system

Abstract

The invention discloses a process for producing powdered milk comprising a multiple resistance nutrition immune optimization system (MRN immune optimization system), which comprises the following steps: carrying out pretreatment on raw material milk and preparing a mixture of docosahexaenoic acid and arachidonic acid; preparing a mixture of an immune protein G and lactoferrin; and adding the mixed materials according to a certain proportion and respectively carrying out homogenizing, sterilization, concentration, spray drying, fluidized bed drying, cooling and packing inspection on the obtained product. The powdered milk produced by the method of the invention mainly comprises the following ingredients: the immune protein (IgG), the lactoferrin (LF), fructooligosaccharide (FOS), oligomate (GOS) and five nucleotides. The invention improves the conventional production process. The fructooligosaccharide (FOS) and the oligomate (GOS) improve intestinal flora. The five nucleotides can keep the immune system of the human body. The mixed material is prepared from the immune protein G and the lactoferrin in an amplified ratio so as to not only guarantee the bioactivity of the immune protein G and the lactoferrin, but also guarantee the quality of the product.

Description

【Technical field】 [0001] The invention belongs to the field of industrial production of formula milk powder for infants and young children, and in particular relates to a production process of milk powder containing multi-resistance nutritional immune optimization system. 【Background technique】 [0002] Infants and children are the fastest growing period in human life, and nutrition and feeding methods at this stage are extremely important for their development. Formula milk powder is the closest to breast milk in composition, and is the most suitable milk substitute for babies besides breast milk. [0003] At present, most formula milk powders on the market imitate the ingredients of breast milk. The formula milk powder removes part of casein and increases whey protein; removes most of saturated fatty acids and adds vegetable oil to increase unsaturated fatty acids, DHA (22 carbon Hexaenoic acid, commonly known as brain gold), AA (arachidonic acid); lactose is also added t...

AI Technical Summary

Problems solved by technology

[0006] 2. Although the nutritional structure of some infant formula milk powder is close to that of breast milk in terms of raw material configuration, some nutrients and biologically active substances lose their proper functions and activities during the production and processing process

Especially for immunoglobulin G (IgG), nucleotides lost their activity through spray drying and other processes in the past wet addition

[0007] 3. In the production process, the fishy smell of the raw materials DHA and AA was not considered, but the embedding technology was used to cover up the fishy smell

[0009] 1. Add DHA and AA by dry method to ensure the fishy smell, but the addition is uneven, the nutritional content is different, and it is unstable

[0010] 2. The traditional process adds DHA and AA to the ingredients. After homogenization and sterilization, the envelope of DHA and AA is destroyed, resulting in a fishy smell

[0013] 1. Failure to maintain the biological activity and composition structure of nucleotides after milk powder production

[0014] 2. Immunity protein (IgG), lactoferrin (LF) are not added through the process improved by the present invention; 5 kinds of nucleotides

[0016] 3. The degree of fishy smell of DHA and AA after entering the process is not judged by experimental data

[0018] It can be seen that the above-mentioned existing infant formula milk powder and its production process obviously still have inconvenience and defects in product formula, production process and use.
