摘  要:
本研究初步尝试了利用超临界CO2萃取技术从红酵母中提取β-胡萝卜素的效果。结果表明,红酵母经酸-热法破壁后,在所确定的最适萃取条件下(萃取压力30MPa、温度40℃、CO2流量20Kg/h、萃取时间90min),β-胡萝卜素萃取率可达0.83%。这说明,利用超临界CO2萃取红酵母β-胡萝卜素有一定的可行性,但萃取率较低,对影响萃取的各种因素有待今后深入探讨。

摘  要:
The extraction of β-carotene in the red yeast cells by supercritical carbon dioxide(SC-CO2) was studied.The determined conditions by the orthogonal design experiments were as follows.Extraction press was 30MPa,temperature was 40℃,CO2 volume was 20 Kg/h and extraction time was 90min.The results showed that SC-CO2 technology for extracting β-carotene in the yeast cells was possible but some factors of influencing the extraction should be further investigated.
