Abstract
The present invention relates to an encapsulated oil, more specifically to an oil encapsulated in lysed microorganisms and to the method for obtaining them.
Claims8
An dehydrated encapsulated oil comprising:
- an encapsulating agent which is a lysed microalgae or cyanobacterium coating;
- and an oil or oil mixture from sources other than the encapsulating agent sources;
- characterized in that the concentration of the oil is between 35% and 80% by weight with respect to the total dry weight of the dehydrated encapsulated oil;
- without excipients other than antioxidants.

A method for obtaining a dehydrated encapsulated oil that comprises the steps of:
- a) adding an oil to microalgae or cyanobacteria, wherein
- i) the added oil of a) is an oil from sources other than these microalgae or cyanobacteria;
- ii) said adding is performed in the presence of water;, and
- iii) the added oil is added in a percentage comprised between 6% and 40% by weight with respect to the total weight of the microalgae or cyanobacteria, plus the weight of the oil, plus the weight of the water;
- b) breaking the cell wall and/or plasma membrane of the microalgae or cyanobacteria by stirring until to produce an emulsion;
- c) homogenizing the emulsion by pressure in a range between 500 and 1000 bars or by ultrasound in a range between 70 khz to 90khz of frequency and 1500W to 1800W of power for a period of time between 5 and 15 min and
- d) dehydrating the homogenized emulsion obtained in step b) c) by lyophilization, thereby producing a dehydrated encapsulated oil comprising an encapsulating agent which is a lysed microalgae or cyanobacterium coating, where the oil or oil mixture is from sources other than the encapsulating agent sources.
