Optimizing Microwave-assisted Extraction Process for Paprika Red Pigments Using Response Surface Methodology
摘要
Abstract
Hot red peppers are used as raw the material, paprika red pigments were prepared with acetone using the method of microwave - assisted organic solvent extraction. The influences of process parameters, including microwave output power, microwave temperature and microwave time on extraction efficiency of paprika red pigments were compared and analyzed; moreover, the extraction process was optimized via single-factor tests and response surface experiments. The results showed that the method of microwave-assisted organic solvent extraction was an effective and practicable one for paprika red pigments extraction, and the spectral properties and characteristic absorption peak of paprika red pigments were similar to those of standard compound. In addition, the most suitable conditions for paprika red pigments extraction were as follows: acetone was used as the extraction solvent, microwave output power was 105 W, microwave temperature was 42 ℃ and microwave time was 2 min. When the optimal conditions were met, the absorbance value of paprika red pigments reached 0. 631.关键词
