中文摘要：
以表皮半黄菠萝为原料鲜切加工后,用乙醛进行熏蒸处理,通过响应面法优化乙醛熏蒸条件,并对鲜切菠萝进行感官评价和品质评价,以确定乙醛熏蒸的最优组合。结果表明：鲜切菠萝采用2.5mL/kg、30%乙醛、熏蒸5h,其品质明显优于未经乙醛熏蒸的产品。经熏蒸后,鲜切菠萝中糖酸比21.98、硬度3110g、弹性1.54mm、弹力0.19、咀嚼性14.2mJ、胶着性937g,明显改善了鲜切菠萝的品质。
英文摘要：
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.
