响应面法优化正己醛、反-2-己烯醛熏蒸鲜切菠萝蜜条件

Optimization on conditions of fumigating fresh-cut jackfruit by n-hexanal, 2- ( E) -hexenal using response surface methodology

摘要: 为确定正己醛、反-2-己烯醛熏蒸鲜切菠萝蜜的最佳工艺条件,以八成熟"马来西亚一号"菠萝蜜为试材,在单因素实验的基础上,采用响应面分析方法之一的中央组合实验设计（Central Composite Design）进行初步探究,进而分析比较在不同因素条件下鲜切菠萝蜜的失重率、亮度值和感官评分。优化所得的最佳工艺条件是:正己醛浓度为95.21mg·kg-1、反-2-己烯醛浓度为108.21mg·kg-1、熏蒸时间约为6h。通过该优化条件的处理,鲜切菠萝蜜的品质得到了极大的改善。

Abstract: In order to determine the optimization on conditions of fumigating fresh-cut jackfruit by n-hexanal, 80%maturity jackfruit was used to experiment material.After the single factor experiment, the central composite design ( CCD) and response surface methodology ( RSM) was used to analyze.The best conditions were 95.21mg·kg- 1of n-hexanal concentration, 108.21 mg·kg- 1of trans- 2- Hexen- 1- al concentration, 6 hours of fumigation. After treatment, the quality of fresh-cut jackfruit was significantly improved.
