Aqueous enzymatic oil extraction of safflower seeds was assisted by Alcalase 2.5L and Celluclast 1.5L. Enzyme type and amount, pH, time, temperature, churning rate, dilution ratios and particle size were varied to determine their influence on the oil amount. The amount of oil recovered was higher using seeds ground to a particle size of <0.6 mm. Response surface methodology was employed for the optimisation of aqueous enzymatic oil extraction conducted with Celluclast 1.5L. When the extraction was assisted by Celluclast 1.5L, the maximum oil amount and yield were 33.3 (% w/w) and 79.7 (% w/w), respectively. The optimum conditions were 48.3 °C; 0.25 mL enzyme g?1 substance; pH, 4.84; resulting oil amount and yield were 28.2 (% w/w) 65 (% w/w), respectively. The predicted critical values were experimentally verified, and an oil amount of 27.1 (% w/w) was achieved. The enzyme treatment did not have any determining effect on the physicochemical properties of extracted oil. 相似文献

仙人掌黄酮类化合物作为一种多酚类物质,具有广泛的生物活性和药理活性。随着食品及化妆品工业的发展与消费观念的改变,黄酮类化合物以纯天然、高活性、见效快、作用广泛等特点日益受到人们的关注。仙人掌黄酮的提取工艺以乙醇为溶剂采用微波法辅助提取。本实验首先分析微波功率、微波时间、乙醇浓度、液料比等单因素对黄酮得率的影响,随后用响应面软件对微波法提取仙人掌中黄酮提取工艺进行优化。结果表明:对于得率的影响程度为液料比提取功率乙醇浓度提取时间。利用响应曲面分析进行回归预测和优化后,仙人掌黄酮得率的最大预测值0.855%,此时的提取条件为:提取时间2.55min,液料比34∶1,乙醇浓度96.5%,超声功率310.6W。经过验证实验得到的提取率为0.832%,与预测值相差2.69%,在可接受范围内。 相似文献

This article describes a comparative study of enzyme and ultrasound techniques for the simultaneous extraction of vitamin C and phenolic compounds from acerola fruit. Ultrasound‐assisted extraction (UAE) took only 6 min to achieve the highest level of vitamin C and phenolic compounds as well as antioxidant activity of acerola juice, while enzyme‐assisted extraction (EAE) took up to 120 min to obtain the maximal values. On the basis of kinetic model of second‐order extraction, the extraction rate constant of vitamin C and phenolics in UAE increased approximately 3.1 and 2.7 times, respectively, in comparison with that in EAE. In addition, the maximal level of vitamin C, phenolics and the antioxidant activity evaluated by 1,1‐diphenyl‐2‐picrylhydrazyl (DPPH), and 2,2′‐azinobis‐(3‐ethylbenzothiazoline‐6‐sulphonic acid) (ABTS) methods in UAE was 4.6%, 3.5%, 4.6% and 3.3%, respectively, higher than those in EAE. Obviously, UAE is a useful method for the extraction of antioxidants from plant materials. 相似文献
