The present disclosure discloses a casein micelle with composition and structural features simulating human milk and a preparation method thereof. The method includes the following steps: adding a citrate ion, a calcium ion, and a phosphate ion to a solution of compound casein to obtain a mixed solution; and then adjusting the pH of the mixed solution to 6.7-7.4, and achieving a constant volume with water to obtain a solution of the casein micelle simulating human milk. Wherein ?-casein, ?-casein, and ?.sub.s1-casein have a mass proportion of 65-71%, 17-23%, and 9-15% in the compound casein respectively. In the solution of the casein micelle simulating human milk, the concentrations of compound casein, citrate ion, calcium ion and phosphate ion were 0.3-0.6%, 1.5-4.2 mM, 4.5-10.8 mM, and 1.1-4.5 mM, respectively. The casein micelle simulating human milk of the present disclosure is similar to human milk casein micelle, and has low allergenicity.

The present invention concerns a method for concentrating dairy proteins. The method includes producting and using negatively-charged ultrafiltration membranes to achieve high hydraulic permeability with low sieving coefficients. The method thus yields good protein concentration at a fast rate.

Provided are methods for producing food products comprising recombinant components, and compositions used in and food products produced by such methods.

The invention relates to cheese and cheese-like products comprising about 0.2 to about 6% by weight ?.sub.s-casein, ?-casein, or a combination thereof, at least about 5% by weight of one or more hydrocolloids comprising one or more starches, and wherein the cheese or cheese-like product has one or more characteristics of a dairy product, such as flavour, taste, aroma, body, appearance, texture, firmness, handling, density, structure, coagulation, binding, leavening, aeration, foaming, emulsification, elasticity, viscoelasticity, melt, creaminess and mouthfeel.

The present invention concerns liquid nutritional compositions comprising at least about 20% (w/w) total protein, and wherein the total protein essentially comprises whey protein and casein. The Compositions are useful for promoting muscle growth in a subject.

Casein compositions for increasing the rate of gastric emptying following ingestion of the composition, increasing the digestibility of a protein composition, or increasing the rate of delivery of amino acids to the blood, or for increasing the blood serum concentration of free leucine in a subject, preferably to substantially the same level as whey protein, the casein being about 10 to about 100% calcium depleted, having a degree of hydrolysis less than about 1% and having an unmodified phosphorylation pattern.

An aqueous modified acid composition for industrial activities, said composition comprising: an alkanolamine and strong acid in a molar ratio of not less than 1:15, preferably not less than 1:10; it can also further comprise a metal iodide or iodate. Said composition demonstrates advantages over known conventional acids and modified acids.

A thermosterilized enteral nutritional composition comprises, per 100 ml of composition, between 8 and 14 g of total proteins, 200 to 350 kcal, the total proteins comprising a quantity of caseinates that is higher than or equal to 55% of the total protein weight of the composition, a quantity of serum proteins that is lower than or equal to 30% of the total protein weight of the composition, and a quantity of caseins that is lower than or equal to 30% of the total protein weight of the composition, the weight ratio of the caseinates to the caseins being higher than or equal to 70/30.

Disclosed is a protein mixture and also to a food composition including such a mixture for feeding adult individuals, sportsmen and sportswomen, elderly individuals, or individuals requiring an improvement in their physical condition, such as individuals who are ill, bedridden, in a weak state, undernourished or suffering from sarcopenia. The protein mixture includes a mixture of plant proteins and of milk proteins in a hydrolyzed wheat protein/milk protein weight ratio A of between 55/45 and 20/80, wherein the milk proteins are a mixture of casein and serum proteins in a casein/serum protein weight ratio B of between 70/30 and 20/80.
