摘要:
The present invention relates to a milk powder comprising caseins and whey proteins wherein the powder upon reconstitution in an aqueous medium comprises casein-whey protein/fat aggregates having a mean diameter value Dv50 of at least 1 mycrom as measured by laser diffraction. The invention also relates to a process for preparing a milk powder including the steps of providing a liquid milk concentrate at T

Dietary fibers have their properties modified by applying a shock wave to a dispersion of the fibers in a fluid carrier. Pressure from a piston, in either a single or a series of compressive strokes or pulses exerted on the dispersion applies the shock wave. Increasing the effect of cavitation caused by the shock wave can enhance the modified properties of the fibers. The resulting pressure treated dietary fiber exhibits reduced calories, higher insoluble fiber content, reduced moisture absorption properties, and greater uniformity from batch to batch.

Process for the preparation of a powder comprising bio active molecules, said process comprising the steps of (i) providing a liquid composition comprising bio active molecules, (ii) optionally pre-heating said liquid composition, provided that the temperature of the liquid composition does not exceed 65° C., (iii) transporting the optionally pre-heated liquid composition to the top of a spray drying tower via a tower feeding line, (iv) raising the temperature of the optionally pre-heated liquid composition using a direct electric volumetric heater located within the tower feeding line, the final temperature of the liquid composition being in the range 60-90° C., followed by (v) transporting the resulting liquid composition via the tower feeding line to the atomizer of a spray-dryer.

A process for the production of a commercial mineral whey product derived from a feed stream of milk or whey, said process including the steps of: primary de-mineralisation of the feed stream, preferably carried out by either membrane separation or ion exchange to produce a high potassium stream and a demineralised stream; secondary demineralisation of the high potassium stream, either by precipitation and subsequent separation of a predominantly calcium-phosphate complex, or by the removal of calcium by ion exchange; concentrating the high potassium stream to obtain a concentrate having a total solids content of around 20 to 60% by weight; and further processing of said concentrated said high potassium stream into a desired form for storage and distribution.

The invention provides a process for preparing a dried modified whey protein concentrate. A whey protein solution is used having less than 5% total solids and a combined calcium and magnesium concentration of less than 70 mmol/kg on a dry basis and a pH of 6.0-7.5. It is heated to greater than 70° C. for up to 60 minutes to denature the whey protein. The solution is then cooled to 40° C.-60° C.; and subsequently spray dried. Alternatively a higher initial concentration of total solids may be used in an embodiment where the heating is carried out on a scraped surface heat exchanger.

The invention provides a gas infused milk product, wherein the gas infused milk product comprises a lactose hydrolyzed concentrated milk infused with a soluble gas. The invention also provides methods of making such a product. Such methods include providing milk (skim milk, 1% milk, 2% milk, whole milk, half and half, cream or other milk product) and concentrating and hydrolyzing the milk with lactase to from a lactose hydrolyzed milk concentrate. The milk can be concentrated in vacuo (in a vacuum) in order to remove the dissolved gasses from the lactose hydrolyzed milk concentrate. Soluble gasses, such as nitrous oxide or carbon dioxide are then introduced into the lactose hydrolyzed milk concentrate to form a gas infused milk concentrate. In one aspect of this invention, the gas infused milk concentrate is then introduced into a stream of carbonated or still water resulting in a gas infused milk beverage.
摘要:
This invention is based on the discovery that there is a relationship between the fouling rate of milk during processing into milk powder products and the .beta.-lactoglobulin phenotype of the cow whose milk is being processed. Milk from .beta.-lactoglobulin BB phenotype cows has a much lower fouling rate than that from .beta.-lactoglobulin AA phenotype cows. The invention consists in a method comprising testing milk from identified cows for the presence of non-fouling .beta.-lactoglobulin variants and recovering and maintaining that milk separate from the fouling variant containing milk. The non-fouling variant or blends of at least 30% by weight of the non-fouling variant are further processed into milk powder products. The invention also consists in a method of selecting a diary herd having only .beta.-lactoglobulin non-fouling variant phenotype cows.
