Abstract
The present invention relates to a method for producing a film, a coating, or a moulded body from yeast biomass, in which the biomass is first disintegrated and homogenized and then further processed into the film, coating, or moulded body. The method is characterized in that an oil-forming yeast, in particular Y. lipolytica, is used as the yeast and the homogenization comprises an enzyme treatment that dissolves the cell wall. The method can be used to produce bio-based and completely biodegradable packaging products that are based solely on renewable and natural raw materials and have good mechanical properties.
Claims11
Method for producing a film, a coating or a moulded body from a biodegradable material, in particular for packaging, which comprises at least the following steps:
- Providing biomass of a yeast,
- Homogenising the biomass, which comprises at least one mechanical treatment of the biomass, and
- Processing the homogenised biomass directly or after addition of one or more further substances to form a film, a coating or a moulded body,
- characterized in that
- an oil-forming yeast is used as yeast, and the homogenisation also comprises a cell wall-dissolving enzyme treatment.
Use of the biomass of an oil-forming yeast, in particular of Yarrowia lipolytica, for the production of a film, a coating or a moulded body.
Film, coating or moulded body which are formed as the main component from the biomass of an oil-forming yeast, in particular Yarrowia lipolytica.
