Conditions Optimization for Acetaldehyde Fumigation of Fresh-cut Pineapple by Response Surface Methodology

Abstract

Abstract: Response surface methodology was applied to optimize the conditions for acetaldehyde fumigation of semi-yellow fresh-cut pineapple in order to achieve the best sensory quality. Fresh-cut pineapple fumigated treatment 5 h with 30% acetaldehyde at the dosage of 2.5 mL/kg showed a notably improved sensory quality when compared with non-fumigated one. The sugar-to-acid ratio, hardness, elasticity, stretch, chewiness and adhesiveness of fumigated pineapple were 21.98, 3110 g, 1.54 mm, 0.19, 14.2 mJ and 937 g, respectively.

Key words: acetaldehyde, fumigation, fresh-cut pineapple
