Embodiment 1
[0041] A method based on fast distinguishing between aldehyde compounds, including the following steps:
[0042] 1) Collect rice in different regions, ZCSMs, ZCSMs, Xihu Xiangmei (XHXM), Fu Linmen Su Soft (FMSR), Guangming Chongming rice (GMCM), Shanglin Xiangmi (SLXM), Wannong Gong Mi (WNGM), classic Royal Gongmi (JDYG), Jinlong Fish Longxiang Mei (JYCX), Jinlong Fish Panjin Earth (JYPJ), Wucong Rice (WCYX), Jinlong Fish Hanfang Northeast Earth (JYHD), Sweet Water Xiangmi (TSXM), Xuelius (XLRS), Jinlongfish High-quality Northeast Earth (JYYD).
[0043] Every time you weigh 150G left and right rice, meters: water = 1: 1.2, cook with rice cooker. After cooking, stir evenly, take 5g of ripe rice on 20 ml of transparent top air jaws into spots. Then, 20 μl of 2-octanol was added, and the quality control was carried out, and then the top empty jaw cap is sealed with the Topylon silica gel. The nature of 2-octanol is stable, and does not react with the target and solvent, and the boiling...
Embodiment 2
[0050] A method based on fast distinguishing between aldehyde compounds, including the following steps:
[0051] 1) Collect rice, ZCSM, ZCSM, Xihu Xiangmi (XHXM), Xihu Sucan (FMSR), Blessing Mei (SLXM), Shanglin Mei (SLXM), Fulinmen Pearl Xiangmi (FMZZ), Classic Royal Gon (JDYG), Jinlong Fish Longxiang Mei (JYCX), Jinlong Fish Panjin Earth (JYPJ), Wuchang Raw Rice (WCYX), Jinlong Fish Hanfang Northeast Millet (JYD), Sweet Water Metal Millet (TSXM), Snow Drans (XLRS), Golden Dragonfish High Quality Northeast Earth (JYYD).
[0052] Every time you weigh 150G left and right rice, meters: water = 1: 1.2, cook with rice cooker. After cooking, stir evenly, take 5g of ripe rice on 20 ml of transparent top air jaws into spots. 20 μl of 18 mg / L of 2-octanol was added, and the quality control was carried out, and the top air jaw cap is sealed with the top of the Teflon silica gel. The nature of 2-octanol is stable, and does not react with the target and solvent, and the boiling point is lo...
Embodiment 3
[0060] A method based on fast distinguishing between aldehyde compounds, including the following steps:
[0061] 1) Collect rice in different regions, ZCSMs, ZCSMs, Xihu Xiangmei (XHXM), Fu Linmen Su Soft (FMSR), Guangming Chongming rice (GMCM), Shanglin Xiangmi (SLXM), Wannong Gong Mi (WNGM), classic Royal Gongmi (JDYG), Jinlong Fish Longxiang Mei (JYCX), Jinlong Fish Panjin Earth (JYPJ), Wucong Rice (WCYX), Jinlong Fish Hanfang Northeast Earth (JYHD), Sweet Water Xiangmi (TSXM), Jinlongfish Milk Emperor (JYRH), Jinlongfish High Quality Northeast End of Jiyd.
[0062] Every time you weigh 150G left and right rice, meters: water = 1: 1.2, cook with rice cooker. After cooking, stir evenly, take 5g of ripe rice on 20 ml of transparent top air jaws into spots. Then 20 μl of 17 mg / L 2-octanol was mass-controlled, and then the top air jaw bottle cover with Tofil silica gel. The nature of 2-octanol is stable, and does not react with the target and solvent, and the boiling point is low...
