ResumoThe effect of soaking conditions on the physicochemical and microbiological quality of jackfruit was evaluated. First, jackfruit pieces were disinfected by 10 min immersion in a solution of 150 mg/L of free chlorine; the jackfruit bulbs were disinfected by 5 min immersion in a solution of 150 mg/L of free chlorine. Then four lots of jackfruit bulbs were generated by immersion in the following aqueous solutions by 5 min: 1.5 g/L potassium sorbate (PS), 1.5 g/L PS, + 10 g/L citric acid (CA), 1.5 g/L PS + 10 g/L ascorbic acid (AA), and 1.5 g/L PS + 10 g/L CA + 10 g/L AA. Each lot was packed in polypropylene boxes and stored at 6 °C. At 12 days were observed significant (P < 0.05) changes on pH, titratable acidity and reducing sugars by effect of soaking solutions. The combined effect of PS, CA and AA influenced significantly (P < 0.05) on the best control of microbial counts.
