A method for producing a mammalian milk like product, for example a human milk like product comprising generating lactocytes derived from mammalian induced pluripotent stem cells (miPSC), for example human induced pluripotent stem cells (hiPSC), and expressing the mammalian milk like product, for example the human milk like product from lactocytes.

Provided is a genetically modified non-human mammal that comprises an anchor DNA sequence inserted at an endogenous locus of a secretory milk protein gene, wherein the anchor DNA sequence comprises a site-specific recombinase recognition site. Also provided is a genetically modified non-human mammal that comprises a transgene inserted at an endogenous locus of a secretory milk protein gene, wherein the transgene encodes a secretory protein and is operably linked to the endogenous promoter of said secretory milk protein gene, and wherein the transgene is flanked by a pair of site-specific recombinase resulting sites. The genetically modified non-human mammals provided can be used for producing the secreted recombinant protein encoded by the transgene from the milk produced by the genetically modified non-human mammals.

Provided herein are cheese and yogurt compositions and the methods of making the same using one or more recombinant proteins.

Provided herein are compositions and methods for producing milk proteins in plants, which allow for safe, sustainable and humane production of milk proteins for commercial use, such as use in food compositions. The disclosure provides recombinant fusion proteins comprising a milk protein, or fragment thereof and a structured mammalian, avian, plant, or fungal protein, or fragment thereof. The disclosure also provides methods for producing the recombinant fusions proteins, and food compositions comprising the same.

Provided herein are compositions and methods for producing milk proteins, which allow for safe, sustainable and humane production of milk proteins for commercial use, such as use in food compositions. The disclosure further teaches methods of increasing the production/accumulation of casein proteins in host cells by co-expressing a kinase capable of phosphorylating the casein protein. Specifically, the disclosure provides host cells comprising a heterologous casein protein and a heterologous casein. Stable transgenic plants expressing heterologous caseins and heterologous kinase proteins are also provided. In some embodiments, the heterologous casein proteins of the disclosure are contained within fusion proteins comprising at least first protein and a second protein, wherein at least one of the first protein and the second protein is a milk protein, or fragment thereof. The disclosure also provides methods for producing the recombinant fusions proteins, and food compositions comprising the same.

The disclosure provides recombinant fusion proteins comprising a milk protein, or fragment thereof and a structured mammalian, avian, plant, or fungal protein, or fragment thereof. The disclosure also provides methods for producing the recombinant fusions proteins, and food compositions comprising the same.

The present invention provides plant-based dairy substitutes and methods thereof. Those substitutes may be a cheese substitute, a yogurt substitute, a coffee creamer substitute and more. The present invention discloses a plant cell culture, preferably, carrot cells, which expresses transgenic casein proteins. This unique casein-expressing culture is then transformed into a slurry, which serves as the platform for the production of the plant-based dairy substitutes. Furthermore, those dairy substitutes are highly nutritious, as they contain beneficial ingredients derived from the plant cells (such as beta-carotene) in addition to high protein (casein) content. The application of carrot cell slurry containing casein proteins to those dairy substitutes provides organoleptic and physicochemical properties enhanced or similar to conventional dairy products. The carrot cells expressing casein proteins can be conserved in a powder form, as the plant cells successfully encapsulate the casein proteins, thus protecting them from physicochemical conditions, such as spray drying.

The present invention generally relates to new process for the preparation of iron (III) casein N-acetyl-aspartylated complexes. The product obtainable according to the method of the present invention may be safely used to the general population or animals in the therapy of iron deficiency. The process of the invention includes the steps of: (a) reaction of casein with N-acetyl-L-aspartyl chloride, to form N-acetyl-L-aspartylated casein, (b) subsequent reaction of the N-acetyl-L-aspartylated casein with ferric chloride; and (c) obtaining the iron (III) complex with N-acetyl-L-aspartylated casein.
