Production of yeast extract from spent brewer’s yeast

Abstract EN

The production of yeast extract was studied because of its importance in the process of preparing and producing the culture media which used in medical and microbiological laboratories.

The raw material used to produce this material is the spent brewer’s yeast that always thrown in the river and causes the contamination, therefore the purpose of using spent brewer’s yeast is to remove the contamination and to produce an important material for preparing the culture media.

Ibnulbitar Center and the Central Public Health Laboratory checked the quality of the yeast extract and the results was accepted.

A basic design of a pilot plant was done.

The design includes selection of equipment, process flow diagram (PFD), process instrument diagram (PID).

Process of production yeast extract was extremely economical because the raw material was available and production running cost is nearly nil, on the other hand the cost of building the pilot plant was very cheap in comparison with importing price of this material, The residue of yeast grinding and was used as a forage.-
