    • 摘要: 用β-葡萄糖苷酶处理香荚兰豆荚,并以HPLC法分析所得到豆荚中香兰素等4个糖苷水解成分的含量变化情况.结果表明,采用外加β-葡萄糖苷酶酶促生香工艺可以促进香荚兰青荚中糖苷化合物分解完全,提高豆荚中香兰素的含量,缩短生香陈化时间,具有潜在的生产应用价值.

    • 摘要: 这是一本关于餐桌植物的“冷知识大全”。如果你是好奇心旺盛的吃货,或是热衷于考究的植物极客,那么这本书便是为你量身打造。为什么我们把小麦、人米、土豆作为主食?为什么我们要栽培含有剧毒氰化物的木薯?为什么我们常吃的坚果是杏仁而不是橡子?为什么兰花有两万多种,人类的食谱却只选择了香荚兰?回答上述问题.

    • 摘要: Vanilla extract was refined by organic solvent extraction. Different solvents were tested for their extractability using electronic nose and sensory evaluation. Solvent composition and number of extraction cycles were optimized for higher retention rates of major components. The volatile components before and after the extraction were compared by gas-chromatography-mass spectrometry (GC-MS). The results showed that the optimized conditions that provide maximum vanillin content (9.48%) were found to be extraction performed 3 times using a mixture (3:7, V/V) of ethyl acetate and n-butanol as extraction solvent.After the extraction,the proportion of aromatic compounds was increased from 35.58% to 51.00%, along with a decrease in the proportion of alkanes from 4.42% to 0.78%. These results can provide a theoretical basis and technical support for the comprehensive utilization of vanilla extract and product development.%采用有机溶剂萃取法对香荚兰浸膏进行精制,通过电子鼻、感官评定确定最佳溶剂,以主要化合物含量为指标优化溶剂比例及萃取次数,利用气相色谱-质谱法检测浸膏精制前后挥发性成分相对含量.结果表明:最佳溶剂为乙酸乙酯-正丁醇、溶剂体积比3:7、萃取3 次时香草醛相对含量最高为9.48%,香荚兰浸膏精制效果较好;浸膏精制后,芳香族类化合物相对含量由35.58%增加至51.00%,烷烃类化合物相对含量由4.42%减少至0.78%.该研究结果可为香荚兰浸膏综合利用及产品研发提供理论参考及技术支持.

    • 摘要: The puncture method was used to analyze the differences in the texture characteristics among Hainan (HI),Papua New Guinea (PNG) and Madagascar (MG).The electronic nose coupled with headspace solid-phase micro-extraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS) was used to analyze the aroma components of vanilla from HI,PNG and MG.The results indicated that the toughness of the epidermis for HI was lower than that of PNG and MG.PNG and MG were not significantly different (p>0.05).The skin hardness for HI and MG was lower than that of PNG,HI and MG showed no significant difference (p>0.05).Internal hardness and firmness of vanilla were shown as HI<MG< PNG.A total of 74 aroma components were identified from the three kinds of vanilla pods through HS-SPME-GC-MS.45,50 and 51 of which were detected in PNG,HI and MG of vanilla pods.The main content of vanillin in HI vanilla was 69.11%,slightly lower than that of PNG (75.15%) and MG (74.36%).Low content and more aroma of the substance with guaiacol,4-methyl guaiacol and 4-methyl phenol were detected.The relative contents of HI and PNG and MG were different.In addition,8 kinds of volatile compounds were found in HI,including formic acid,2-ethylfuran,2,4,5-trimethyloxazole,2,3,5,6-tetramethylpyrazine,1,2-dimethoxybenzene,Damascone,vanillic acid and palmitic acid.%采用穿刺法分析海南(Hainan,HI)、巴布亚新几内亚(Papua New Guinea,PNG)、马达加斯加(Madagascar,MG)香荚兰质构特性差异,利用电子鼻结合顶空固相微萃取气质联用(HS-SPME-GC-MS)技术对HI与PNG、MG香荚兰挥发性成分进行分析比较.质构特性结果显示:表皮韧性大小关系为HI< PNG、MG,PNG与MG差异不显著(p>0.05);表皮硬度表现为HI、MG<PNG,MG与HI差异不显著(p>0.05);内部硬度和紧实度均表现为HI<MG<PNG;电子鼻结果显示主成分分析(PCA)图谱上可以将HI与PNG、MG香荚兰进行区分;HS-SPME-GC-MS从三种香荚兰中共检测出74种挥发性成分,HI、PNG、MG分别检测出45、50和51种,主要呈香物质香草醛在HI中的相对含量为69.11%,相对于PNG(75.15%)和MG(74.36%)略低;检出的低含量且强烈香气物质愈创木酚、4-甲基愈创木酚、4-甲基苯酚在HI中的相对含量与PNG、MG均有所差异;此外,在HI中检出8种特有的挥发性化合物,分别是甲酸、2-乙基呋喃、2,4,5-三甲基唑、2,3,5,6-四甲基吡嗪、1,2-二甲氧基苯、大马士酮、香草酸、十六烷酸.
