Abstract

Carotenoids are known for their lower environmental pollution, lower costs, shorter extraction time compared to regular extraction methods and higher extraction efficiency. Ultrasound has significant advantages in the extraction of a great number of biologically active compounds including carotenoids. Benefits of using ultrasound for extraction of various compounds are numerous and include effective mixing and micro-mixing, more efficient energy transfer, reduced thermal and concentration gradients, reduced temperature. The aim of this work was to investigate the influence of two-frequency ultrasound main parameters such as ultrasonic intensity, sonication time, and temperature. Application of two-frequency ultrasound (simultaneous influence of ultrasound with frequency of 20–46 kHz, intensity of 1.5–2.5 W/cm 2 and frequency of 1.0–2.0 MHz, intensity of 2.0–3.0 W/cm 2 ) raises the percentage of b -carotene extraction from biomass of the fungus Blakeslea trispora from 90–92% up to 98–99% in comparison with one frequency ultrasound. The recommended oil temperature for the extraction process is 35 °C, because lower temperature leads to reduction of percentage of β -carotene extraction, and higher temperature promotes unjustified increase of expenditure of energy.

双频超声高效提取三孢黑霉中β-胡萝卜素

与常规提取方法相比，类胡萝卜素以其较低的环境污染、较低的成本、较短的提取时间和较高的提取效率而闻名。超声波在提取包括类胡萝卜素在内的大量生物活性化合物方面具有显著优势。使用超声波提取各种化合物的好处很多，包括有效的混合和微混合、更有效的能量传递、降低的热梯度和浓度梯度、降低的温度。本工作的目的是研究双频超声主要参数如超声强度、超声时间和温度的影响。与单频超声波相比，双频超声波的应用（频率为20–46 kHz，强度为1.5–2.5 W/cm 2，频率为1.0–2.0 MHz，强度为2.0–3.0 W/cm 2的超声波同时影响）可将从真菌Blakeslea trispora生物量中提取b-胡萝卜素的百分比从90–92%提高到98–99%。提取过程的建议油温为35°C，因为较低的温度会导致β-胡萝卜素提取百分比的降低，而较高的温度会不合理地增加能量消耗。
