Optimization of Citrus complex biopreservatives microcapsules technology by response surface methodology

利用响应面法对柑橘复合生物保鲜剂的微胶囊化工艺进行研究。探讨不同壁材、壁材配比、壁芯比和固形物质量分数对柑橘复合生物保鲜剂包埋率的影响,在单因素基础上,采用响应面分析方法,进一步研究各自变量及其交互作用对复合生物保鲜剂包埋率的影响,并对其工艺参数进行优化。结果表明:柑橘复合生物保鲜剂微胶囊的最佳工艺条件为壁材配比2.50 g/g、芯壁比3.00 g/g、固形物质量分数25.0%,在此最佳工艺条件下,柑橘复合生物保鲜剂的包埋率达87.21%。此微胶囊化的复合生物保鲜剂,能保护保鲜剂的活性物质,提高柑橘的保鲜时间和效果,有望用于柑橘贮藏保存和保鲜的工业化生产中。

Response surface methodology was applied to optimize the microcapsule conditions of Citrus complex Biopreservatives.The effects of different wall materials, the ratio of wall material ,wall core ratio and solid content on the citrus complex biopreservatives embedding rate were discussed. Based on the single factors experiments, the impact of each variable and their interaction on the embedding rate of citrus complex biopreservatives were investigated by response surface analysis. The results showed that optimal parameters for embedding rate of citrus complex biopreservatives microcapsules were as follows：the ratio of wall material of 2.50 g/g,wall core ratio of 3.00 g/g, solid content of 25.0% .In the optimum conditions,the embedding rate of citrus complex biopreservatives was 87.21%.The microcapsules of complex biopreservatives can protect the biopreservative of active substances and improve the preservation time and effect of citrus,and was expected to be used in the industrial production of citrus storage and preservation.
