摘要:
为研究不同冷冻干燥温度对荠菜挥发性物质的影响,采用不同温度(5 ℃、10 ℃、15 ℃和20 ℃)对荠菜进行冷冻干燥处理,利用顶空固相微萃取结合气相色谱-质谱联用技术对荠菜中的挥发性物质进行检测。结果显示:与其他处理组相比,10 ℃冷冻干燥处理产品中挥发性成分种类最多,为53种,其中醇类物质如叶醇、1-戊烯-3-醇、苯乙醇和1-己醇含量较其他处理组高,酯类物质如亚硝酸异戊酯、乙酸叶醇酯、正己酸乙酯、二氢猕猴桃内酯和3-己烯酸乙酯等相对含量较高,酮类物质如甲基庚烯酮和3-甲基-2-庚酮含量较高。酸类物质种类在10 ℃冷冻干燥产品中最为丰富,新鲜荠菜中的3-氨基-2,3-二氢苯甲酸和2-甲基-4-戊烯酸在10 ℃冷冻干燥产品中得到了较好的保留,10 ℃冷冻干燥处理荠菜中醛类物质和烃类物质损失相对较小。综上所述,在本试验条件下,在-20 ℃预冻6 h,冷肼温度-85 ℃,真空度0.5 MPa,加热板温度10 ℃,干燥时间14 h能够较好地保留荠菜的挥发性成分。
Abstract:
The wild Capsella bursa-pastoris L. was freeze-dried at 5 ℃, 10 ℃, 15 ℃ and 20 ℃, respectively, and the combination of head space-solid-phase micro-extraction and gas chromatography (HS-SPME-GC-MS) was used to detect the volatile components. As many as 53 types of volatile components were detected at 10 ℃, among which, alcohols including cis-3-hexen-1-ol, 1-pentene-3-alcohol, benzene ethanol and 1-hexanol, esters including amyl nitrate, acetic acid leaf alcohol ester, ethyl caproate, two hydrogen actinidia lactone and 3-hexenoic acid ethyl ester, ketones including methyl heptenone and 3-methyl-2-heptanone presented higher contents than those treated at other temperatures. Acids in 10 ℃ dried products were the most abundant, and 3-amino-2,3-two hydrogenation of benzoic acid and 2-methyl-4-pentenoic acid in fresh samples were maintained to the greatest contents. The losses of aldehydes and hydrocarbon were relatively small in 10 ℃ dried products. In conclusion, the flavor of C. bursa-pastoris L. was well maitained under the following conditions: sample loading 50 g, pre-freezing at -20 ℃ for 6 h, cold trap at -85 ℃,vacuum degree at 0.5 MPa,freeze-drying at 10 ℃ for 14 h. 
