The effect of different porosity of onggis, Korean earthenware, on the fermentation of kochujang was investigated. The porosity was controlled with glazing treatment. Three kinds of onggis were made: one with no glazing treatment, one with outside glazing treatment, and one with both inside and outside glazing treatment. During 4 month fermentation of kochujang in porosity-controlled earthenwares, physical, chemical, microbiological, and sensory quality attributes were monitored. Higher protease activity and higher contents of amino nitrogen, free amino acids, and total neucleotide were observed in kochujang fermented in the onggi with outside glazing treatment, which might have resulted in better sensory quality. Onggi with medium porosity could be effective for fermentation of kochujang.
