从番茄皮渣中提取番茄红素工业生产工艺的优化

Optimization of manufacturing technique for extracting lycopene from tomato peel

[目的]以产品总类胡萝卜素含量和产品得率为指标,建立一种利用混合溶剂从番茄皮渣中提取番茄红素的工业生产工艺。[方法]在单因素实验的基础上,考察了烘干温度、番茄粉的粉碎粒度、番茄粉与萃取溶剂的比例、萃取温度、萃取次数等对番茄红素得率的影响。[结果]番茄红素的最优工业化生产工艺为:烘干温度270℃,番茄粉透过40目,固液比1∶3(kg/L),番茄粉萃取温度33℃,萃取次数2次,此条件下番茄红素的总类胡萝卜素含量为85.56%,番茄红素的得率为95.01%。[结论]该工业生产工艺番茄红素得率高,生产成本低,并可得到较高质量的产品。

[Objective] In this study,manufacturing technique of lycopene from tomato peel was optimized and total carotenoids and yield were used as the indexes.[Method] The impacts of drying temperature,the sample fineness,ratio of tomato powder and extraction solvent,extraction times,extraction and temperature were investigated.[Results] The results showed that the optimized manufacturing technique of tea polyphenols was as follows：drying temperature 270℃,the tomato peel were smashed to pass through the 40 mesh sieve,ratio of solid to liquid at 1 ∶ 3 （kg/L）,extraction temperature 33℃,extraction twice.Under the above conditions,Tthe total carotenoids was 85.56％.The lycopene yield was 95.01％.[Conclusion] The optimized technique was an efficient method with high total carotenoids,high lycopene yield and low cost.
