摘要

为比较4种不同干燥方式对北虫草品质的影响,分别采用远红外、真空冷冻、热风循环、自然干燥对北虫草进行干燥,测定不同干燥方式下北虫草干制品的活性成分含量、物理性质、复水后的感官质量、体外抗氧化活性以及抗炎活性。结果表明,真空冷冻干燥的北虫草复水性和持油性最优,对北虫草颜色有良好保护,复水后的感官质量最佳,并且最大程度地保留了生物活性物质,虫草素(22.52 mg/g)、虫草多糖(134.05 mg/g)、蛋白质(200.5 mg/g)、总黄酮(12.48 mg/g)含量最高;DPPH自由基、ABTS阳离子自由基和·OH清除能力的半抑制浓度 (half inhibitory concentration,IC50)分别为0.829、0.508、3.609 mg/mL;透明质酸酶和牛血清白蛋白变性抑制率的IC50分别是21.114和41.231 mg/mL,较其他3种干燥方式制得的干品差异显著(P<0.05);几种干燥方式的综合品质结果为:真空冷冻>红外干燥>自然干燥>热风干燥。综合考虑,真空冷冻干燥处理对北虫草品质显著优于其他干燥方式,可作为北虫草适宜的干燥方式推广应用。

Abstract

To compare the effects of four different drying methods on the quality of Cordyceps militaris, C. militaris was dried by far-infrared, vacuum freezing, hot air circulation, and natural air drying. The content of active components, physical properties, sensory quality after rehydration, in vitro antioxidant activity, and anti-inflammatory activity of C. militaris dried products under different drying methods were measured. Results showed that vacuum freeze-dried C. militaris had the lowest water content, the best rehydration and oil retention, the best color protection, the best sensory quality after rehydration, and retained bioactive substances to the greatest extent. The contents of cordycepin (22.52 mg/g), C. militaris polysaccharide (134.05 mg/g), protein (200.50 mg/g), and total flavonoids (12.48 mg/g) were the highest. The IC50 of DPPH radical, ABTS cationic radical and hydroxyl radical scavenging capacity were 0.829, 0.508, and 3.609 mg/mL respectively. The IC50 of hyaluronidase and bovine serum albumin denaturation inhibition rate were 21.114 and 41.231 mg/mL, respectively. The activity was significantly better than that of the dry products prepared by the other three drying methods (P<0.05). The comprehensive quality results of several drying processes were as follows: vacuum freezing > infrared drying > natural air drying > hot air drying. Considering the vacuum freeze-drying treatment, the quality of C. militaris was significantly better than other drying methods, it could be popularized and applied as a suitable drying method for C. militaris.
