1.  The Invention
	Title: Yeast derivated products as natural food additives The problem the inventor(s) wanted to solve: The subject of the invention is optimization of process to obtain natural food additives from baker’s and spent brewer’s and wine yeast towards entire utilization of cell wall constituents. Description: Yeast derivated products such as yeast autolysates and yeast extracts are obtained as a result of controlled autolysis (temp. 50^0C; pH 5,5; 24 h) with different types of inductors such as: glucose, ethanol, NaCL, organic acids. Such obtained yeast autolysate is spray-drying or cell wall are separated by centrifugation in order to obtain yeast extract. Yeast extract is preserved in form of yeast spread or spray drying. Presentation: Poster Fields of application: Described above methodology of obtaining yeast derived natural food additives is economicly justified method of spent brewer’s yeast utilization. Advantages: Yeast autolysates bind fats and water, are good sensory additives, have beneficial aminoacids composition. They are used as components of nutrient media in microbiology, additive to baker’s products, meat and mushroom stuffing. Yeast extracts are well soluble in all pH spectrum, bind fats, color food. Stage of development: prototype, Documentation available: Yes –
