Fatty acids profiles and antimicrobial activity of crude coconut fat hydrolysates obtained in solid-state cultivation system with a selected yeast strain Yarrowia lipolytica RO13 were performed. A preliminary step regarding extracellular lipase production and solid state enzymatic hydrolysis of crude fat at different water activity and time intervals up to 7 days was also applied. Gas chromatography-mass spectrometry analysis was used for quantification of medium chain saturated fatty acids (MCSFAs) and the results revealed a higher concentration of about 70% lauric acid from total fatty acids. Further, antimicrobial activity of fatty acids against some food-borne pathogens (Salmonella enteritidis, Escherichia coli, Listeria monocytogenes and Bacillus cereus) was evaluated. The minimum inhibitory concentration of the obtained hydrolysates varied from 12.5 to 1.56ppm, significantly lower than values reported in literature. The results provide substantial evidence for obtaining biopreservative effects by coconut fat enzymatic hydrolysis.
