The invention relates to a process for the manufacture of a perchlorate depleted milk based on nanofiltration of dairy raw materials. The invention further relates to methods for the preparation of an infant formula base using said perchlorate depleted milk. The invention also envisages a perchlorate depleted retentate fraction used to produce a perchlorate depleted milk and infant formula, an assortment comprising said formula and a system for the manufacture of an infant formula comprising a nanofiltration module.

Methods of decreasing muscle atrophy and/or promoting muscle regeneration in a subject at risk of muscle atrophy comprise orally administering a nutritional composition comprising at least one of protein, fat and carbohydrate, and bovine milk-isolated exosomes comprising intact exosomes. In specific embodiments, the subject suffers from malnutrition, acquired immune deficiency syndrome (AIDS), cancer, diabetes, chronic obstructive pulmonary disease (COPD), amyotrophic lateral sclerosis (ALS), non-alcoholic fatty liver disease (NAFLD), or a burn injury, or has undergone clinical corticosteroid treatment.

Disclosed are methods for preparing aseptic dairy compositions having at least 35 wt. % solids, and often from 40 to 50 wt. % solids, by subjecting a dairy product to forward osmosis following by a heat treatment step. The heat treatment step can include UHT sterilization via direct steam injection or direct steam infusion. Subsequently, the aseptic dairy composition can be dried to form a dairy powder composition.

Processes and systems are provided for aggregating whey protein including preparing a whey protein solution containing native whey protein, adjusting the pH of the whey protein solution, denaturing at least a portion of the native whey protein, separating the denatured material and processing the denatured material by shearing to form whey protein aggregates. Also provided are whey protein aggregates and uses thereof, such as in the production of dairy products or in cheesemaking.

The disclosure relates to a method of making a beverage comprising a milk protein concentrate (MPC), a beverage comprising an MPC, an MPC or use of a MPC. More particularly, this disclosure relates to treatment of an MPC to allow for heat homogenisation of a beverage containing the MPC, while reducing occurrence of malodour and/or egg-type or sulphur-type smell and/or taste.

Suggested is a process for the production of a UHT milk with improved taste characteristics, comprising the following steps: (a) Providing a raw milk; (b) Separating the raw milk into a skimmed milk fraction and a cream fraction; (c) Microfiltration of the skimmed milk fraction, obtaining a casein-containing retentate R1 and a fine whey as permeate P1; (d) Ultrafiltration of the fine whey of step (c), obtaining a permeate P2 that is rich in lactose and minerals, and a protein-rich retentate R2; (e) Pasteurization of the retentate R2; (f) Mixing the cream fraction, the retentate R1 and the permeate P2, obtaining a mixed fraction M1; (g) Ultra-high temperature treatment of the mixed fraction M1 of step (f); and (h) Mixing the ultra-heat treated fraction M1 of step (g) with the pasteurized retentate R2 of step (e), obtaining the target product.

Disclosed are processes for producing high protein, Greek yogurt products. Such processes can include a step of concentrating a skim milk product to produce a protein-enriched milk fraction, which then can be combined with one or more additional milk fractions to form a yogurt base. The yogurt base is inoculated with a yogurt culture and fermented, and at least a portion of the acid whey is removed from the fermented product using a ceramic ultrafiltration membrane system to form the Greek yogurt product.

Processing of milk raw material produces a dairy salt. Preliminary treatment of the milk raw is carried out, with pasteurization and its concentration by nanofiltration through a filter with a pore size of 0.001-0.01 μm, subsequent filtration of the obtained nanofiltration permeate through a membrane module with a pore size of 0.0001-0.001 μm of a reverse osmosis unit, electrodialysis of the obtained RO retentate, concentration of the concentrate or its concentration and drying. The dairy salts may be manufactured and used to salt food products, beverages, granulated cottage cheese, potato chips, crackers, and dips. A masking fraction with organic acid, amino acid, fatty acid, and sugar portions successfully hides the off-notes otherwise associated with potassium compositions. Food products salted with any of the dairy salts described herein achieve reduced sodium content without compromising flavor.

An outlet (3) for fluid feed of a first membrane module (1a) is connected to a fluid inlet (2) of a second membrane module (1b), and if further membrane module(s) is/are present, the outlet (3) for fluid feed of a previous membrane module (n−1) is connected to the fluid inlet (2) of a following membrane module (n), and for the last membrane module (n), the outlet (3) for fluid feed is connected to the fluid inlet (2) for fluid feed of the first membrane module (1a). An amount of fluid feed is continuously pumped with pressure PB through a loop of n membrane modules that are serially connected, the fluid feed and permeate flow concurrently through each of the n membrane module(s), generated permeate is continuously drained from each membrane module through a permeate outlet, permeate pressure at the permeate outlet of each membrane module is controlled within a range.

The present invention relates to a novel method for preparing acid-gellable whey protein aggregates in the form of concentrated suspensions or powders. Moreover, the present invention relates to a novel composition containing the acid-gellable whey protein aggregates, to a food product ingredient comprising the novel type of acid-gellable whey protein composition, and to a food product comprising the novel type of acid-gellable whey protein composition.
