Estimating the term…
The present invention relates to a method for preparing a yeast protein concentrate, said method comprising the lysis of yeast cells in a suspension that was adjusted to a particular pH prior to lysis, subsequently subjecting the soluble fraction obtained from lysis to filtration to reduce the content of molecules smaller than 30 kDa, and optionally drying the solution obtained from filtration. The present invention further relates to a yeast protein concentrate obtainable by the method of the invention. The yeast protein concentrate comprises a high amount of proteins which are still folded and are therefore capable of aggregation to form a solid protein matrix upon heating. In addition, the yeast protein concentrate of the invention will be of unobtrusive taste and is therefore particularly suited for use in the preparation of food items, such as meat substitute products.
Method for preparing a yeast protein concentrate comprising non-denatured yeast protein molecules, said method comprising
Yeast protein concentrate, such as a Yeast protein concentrate powder, comprising a mixture of proteins, wherein the folded proteins included in the protein concentrate unfold at a temperature range between 45° C. and 83° C.
Yeast protein concentrate comprising at least 55% (w/w) total crude protein per dry matter, and wherein at least 40% of the proteins in the concentrate have an apparent size larger than 60 kDa.
