The phrase "acid casein" is correct and usable in written English.
It can be used in contexts related to food science, nutrition, or dairy products, specifically referring to a type of protein derived from milk.
Example: "Acid casein is often used in the production of cheese and other dairy products due to its unique properties."
Alternatives: "casein protein" or "milk protein".
The effect of agitation on the coagulation time (CT) during the precipitation of mineral acid casein curd from skim milk was investigated using a colour-change technique.
Water analysis showed that nearly 100% of large organic contaminants such as humic acid, casein, and most of the phosphate ions (below detection limit), were removed by the FO membranes but allowed small amount of SDS and NH4+ to permeate across.
The skim milk was cooled to 45°C and an acid casein precipitate was formed by adding lactic acid (88% food grade) to a pH of 4.6.
The diet contained (per kg) 200 g acid casein, 502 g glucose, 160 g palm oil, 40 g corn oil, 20 g cellulose, 35 g mineral mix (without calcium) and 10 g vitamin mix according to AIN93 recommendations [ 70].
Rats were fed purified diets containing per kg: 200 g acid casein, 326 g cornstarch, 174 g glucose, 160 g palm oil, 40 g corn oil, 50 g cellulose and vitamin and mineral mix (without calcium) according to AIN-93[ 41].
For isolating total mycelial RNA, one mL of conidial suspension (4 × 10-4 conidia mL-1) was incubated in complete medium (0.6% yeast extract, 0.3% acid casein hydrolysate, 0.3% enzymatic casein hydrolysate, 1% sucrose) at 22-25°C 22-25°Ch with constant shaking at 150 rpm.
Batch cultures of mixed rumen microorganisms were used to study effects of different concentrations of fumarate on fermentation with various N sources (ammonia as ammonium bicarbonate, casein amino acids, casein peptides, gelatin peptides) and feeds (bermudagrass hay, mixed diet of 60% bermudagrass hay plus 40% concentrate) for 6 and 24 h, respectively.
The enzyme catalyzed trans-sialylation using either 2-O- p-nitrophenyl -α-d-N-acetylneuraminic acid or casein glycomacropeptide (whey protein) as the sialyl donor and lactose as the acceptor, resulting in production of both 3′-sialyllactose and 6′-sialyllactose.
The present study reports an engineered poly-l-lactide-co-glycolic acid (PLGA)–casein polymer protein hybrid nanocarrier 190 ± 12 nm in size entrapping a combination of chemically distinct (hydrophobic/hydrophilic) model drugs.
Sephadex G-200, bovine serum albumin (BSA), ethylene diamine tetra acetic acid (EDTA), casein, β-mercaptoethanol, phenyl methyl sulphonyl fluoride (PMSF) and media components were products of Sigma-Aldrich, St Louis, MO, USA.
Thus, dietary L-ornithine and L-citrulline reproduced all actions of individual amino acids and casein.
