自1930年代以来,在美国,长期以来的CHRSitmas传统仍然是一种普遍的做法 - 为圣诞老人拿出一盘饼干和一杯牛奶。1
现在这个赛季结束了,新的一年决议就完成了,圣诞老人在一个晚上吃了超过3亿个饼干,这很难降低腰部的大小,这要归功于美国许多家庭的慷慨大方。2
姜饼人是标志性的饼干,在本赛季食用的数百万饼干中脱颖而出。姜饼gets its distinct flavor from a blend of molasses (dark brown sugar) and gingerbread spice – a mixture of ginger, cardamom, cinnamon, cloves, nutmeg and allspice.
这些香料中的每一个都提供一系列健康益处。例如,姜舒缓恶心和呕吐的症状,并减轻炎症和疼痛的类型;3肉桂和肉桂有助于调节2型糖尿病和肥胖的结果。4
Using B&W Tek’s portal Raman with BWID software, a Raman spectral library of spices can be easily assembled. Alternatively, using the library function of a handheld Raman can also help identify bags of unknown or unlabelled spices you may have in your kitchen or wish to buy in the market.
B&W TekRaman Systems配备532 nm,785 nm或1064 nm激光器。为了从香料,便携式拉曼1064-nm系统产生最佳的拉曼光谱,例如I-Raman Ex,I-Raman Prime-1064,Stram-1064,或Handheld Raman 1064-NM系统,例如TacticId-Mobile,TacticId-1064或Nanoram-- nanoram---建议1064。
Using a light source with this wavelength significantly decreases the powerful fluorescence emitted by dark and natural samples. The Raman spectra acquired from nine different spices using STRam-1064 are displayed in Figure 1a, while Figure 1b exhibits the library search result of cinnamon utilizing the BWID software with a spectral library.
相应地,可以在Tacticid-1064中生成香料库,并用于确定未知香料的容器(图2)。使用低激光功率至关重要,因为在强烈的激光下,香料可以燃烧。
这B&W TekRaman system laser power可以以1%的增量进行调整,使其非常适合从易燃样品中获取拉曼光谱。
