A composition is provided that provides a nutritionally complete calorically dense formula suitable for use as a ready-to-use liquid composition that does not require reconstitution and admixing, which contains intact whey protein in high concentration and which is shelf stable for up to 6 months or more at ambient temperature.

A method for preparing a modified whey protein concentrate (WPC) or whey protein isolate (WPI) is described. It involves (a) providing an aqueous WPC or WPI solution having a protein concentration of 15-50% (w/v), at a pH of 4.7-8.5; (b) heat treating the solution to more than 50° C., for a time that allows protein denaturation to occur; the heat treating comprising heating the solution while under conditions of turbulent flow. At the end of the heat treatment, the heat treated material may be promptly transferred to a drier or to be mixed with other ingredients. The heat-treated WPC or WPI is not subjected to a mechanical shear process prior to the transfer other than where liquid is converted into droplets to facilitate drying. The modified WPC is useful in the manufacture of food and drinks where a high protein content is desired without undesirable changes in texture.

A novel approach is described for reversing aggregation and increasing refolding by application of hydrostatic pressure. A protein of interest in an aggregated, or inclusion body, or other non-native or inactive state is subjected to high hydrostatic pressure. This treatment denatures the protein to states (or conformations) competant for refolding and results in increased formation of native protein once pressure is released. The technique can facilitate conversion non-native proteins, including inclusion bodies and aggregates to native proteins without addition of chaotropic agents, changes in buffer, or large-scale dilution of reagents required for traditional refolding methods.

Disclosed are freeze-dried plasma formats specifically designed for the trauma care field. Blood plasma is subjected to a glucose removal step, a protein fraction up-concentration step and addition of stabilizers prior to freeze-drying. Preferable stabilizers are glutamine dipeptides, glutamine and glycine. The glutamine based formulation is added direct to plasma and serves three main purposes: 1) Increases stability of plasma proteins and stabilizes pH in freeze-dried state; 2) Increases stability of plasma proteins against Gamma Irradiation and thus allows for the application of a terminal sterilization step; 3) Introduces supplements beneficial to the trauma patient.

The invention discloses a recombinant human fibronectin III1-C (rhFNIII1-C), and a preparation method and application thereof. The preparation method comprises the following steps: optimizing a targetgene segment of the target protein according to codon expression preference, and inserting the obtained gene segment into pET-32a to construct a recombinant plasmid; transforming and introducing therecombinant plasmid into an expression vector BL21(DE3), and carrying out screening to obtain positive clone bacteria capable of realizing efficient soluble expression; carrying out enlarging fermentation culture on the positive clone bacteria, carrying out induced expression, performing crushing and centrifuging to obtain a supernatant, and carrying out purification through elution with a His-tagaffinity chromatography column, dialysis, filtration and other steps to obtain a high-quality rhFNIII 1-C solution with a protein concentration of 1.0 mg/mL or above and a purity of 90% or above. According to detection and observation results of cell adhesion promoting tests, the rhFNIII1-C has the performance of obviously promoting adherence and adhesion of MDBK cells and Balb/c/3T3 cells and rapid division and growth of the cells, which indicates that the rhFNIII1-C has huge potential of being used as a raw material and a finished product for cosmeceuticals and medical skincare.

The present invention belongs to the field of animal feed, particularly to a cattle feed based on bamboo shell. The cattle feed based on bamboo shell comprises the following components in percentage by mass: 26-28% of leymus chinensis, 25-27% of corn, 5-7% of soybean meal, 2.5-3.5% of wheat bran, 4.5-5.5% of rapeseed meal, 0.4-0.6% of salt, 0.4-0.6% of calcium hydrogen phosphate and 30-35% of bamboo shell silage. The total mass percentage of the components is 100%. In the formulation, the leymus chinensis is adopted to increase ingestation amount. If fresh grass is used alone, the growth of animals will be affected. The feed effectively utilizes the waste bamboo shell widely existed. Feeding cattle with the feed is conducive to the synthesis of sugars and carbohydrates, increases the microbial protein concentration in rumen, and increases the utilization rate of protein.

It is described a process to obtain increased milk production and/or greater milk protein concentration using supplements with a fatty acid mixture or through production of specific fatty acids within the animal. The process or the supplementation of the product described in this invention (supplements formulated with fatty acids mixtures and with adequate levels of metabolizable protein) allows greater efficiency and/or better quality and/or a healthier mammal with improved productivity. The process includes supplementation of specific types of fatty acids with or without ruminal protection to ruminants and, generally, a diet with metabolizable protein energy ratio greater than the one suggested by the state of the art. The process may include the production of the said compounds (conjugated fatty acids) on the animal itself from fat, certain compounds and microorganisms added to the diet capable of modifying the environment of the gut. The supplementation includes offering fatty acids capable of altering animal metabolism, as well as offering normal fatty acids (which do not change metabolism which, given some conditions in the rumen environment, can change their molecular structure and transform themselves in fatty acids capable of affecting tissue metabolism (including increasing protein content and yield). Both, the offering of the fatty acid with metabolic effects, as well as the production of these active fatty acids in the gut, make possible increases in the concentration and/or production of milk protein.
