A process for the preparation of a liquid or semi-liquid bioactive dairy composition containing 20-90% retained bioactive IgG, for use as an ingredient in a ready-to-eat (RTE) or ready-to-drink (RTD) food product, includes the steps of a) combining a bioactive powder containing a colostrum powder and/or milk powder containing whey proteins, and immunoglobulin G (IgG), wherein the ratio of whey protein: IgG in the bioactive powder is between 1.74:1 and 3.05:1; water and a food grade acid to form a bioactive dairy composition with a pH of 2.5-4.0, and b) heat treating the bioactive dairy composition to between 67-145° C. at ambient pressure.

The present invention is a system and method for performing freeze drying of small quantities of a liquid for personal use, wherein a liquid material is disposed within a single-use container, the container is then coupled to a small-scale freeze-drying unit which extracts liquid from the material in the container using a freeze-drying process, and the freeze-dried material is then left in the container and the container is stored until rehydration. The container may be a specialized single-use container that may be used to rehydrate the liquid and then fitted with a delivery device to feed an infant or child.

The present disclosure discloses a milk powder containing maltopentaose trehalose instead of maltodextrin and a preparation method thereof, and belongs to the field of processing of dairy products. In the present disclosure, a formula milk powder containing maltopentaose trehalose instead of maltodextrin includes the following raw materials in parts by mass: 85-90 parts of fresh milk, 1-2 parts of maltopentaose trehalose, 5-10 parts of vegetable oil, 1-2 parts of a desalted whey powder, 1.5-3 parts of a concentrated whey protein powder, 0.5-0.8 parts of lactose, 0.05-0.1 parts of a multivitamin, and 0.05-0.1 parts of a complex mineral. Differences in physical and chemical properties of products due to a nonuniform polymerization degree of maltodextrin are reduced, and the problem that a Maillard reaction is likely to be induced when the maltodextrin is mixed with an amino acid or protein is solved.

A solid food has a solid form obtained by compression molding a powder. Where a dissolution process from the solid food starting to dissolve until completely dissolving is measured over time on the basis of electric conductivity, times at which a dissolution ratio where electric conductivity at the time of finish of dissolution is 100%, reaches 20%, 63%, and 95% are t.sub.20, t.sub.63, and t.sub.95, and times (sec) at which the dissolution ratio of a reference solid food, formed under conditions in which a difference in weight with the solid food is within ±0.3%, a difference in surface area is within ±2%, a difference in hardness is within ±4%, and a humidification treatment temperature is 100° C. or lower, reaches 20%, 63%, and 95% are t.sub.20ref, t.sub.63ref, and t.sub.95ref, a solubility index (I.sub.d) represented by the following Formula (1) is less than 1.

I.sub.d=(t.sub.20/t.sub.20ref+t.sub.63/t.sub.63ref+t.sub.95/t.sub.95ref)/3  (1)
