 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Analysis of Aroma Compounds in Trapping Solvents of Smoke from Tian Op, a Traditional, Thai, Scented Candle) ผู้เขียน:Wanwarang Watcharananun, Kittiphong Haungrak สื่อสิ่งพิมพ์:pdf AbstractTo study the composition of “Tian Op” smoke, gas chromatography-olfactometry, aroma extract dilution analysis (AEDA) and gas chromatography-mass spectrometry (GC-MS) were applied to identify the potent odorants in smoked flavoring using three trapping solvents: propylene glycol, glycerol and water. Based on the results of AEDA-calculated odor-activity values, the predominant odorants in the Tian Op flavoring were vinyl ketones (C5-C9), n-aldehydes (C5-C11), (E)-2-unsaturated aldehydes (C8- C11) and ?-1-unsaturated aldehydes (C8 and C9). These components were found in the highest quantities when propylene glycol was used as the trapping solvent, followed by glycerol and water, respectively. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Subchronic Toxicity of Liquid Smoke from ‘Tian Op’ in Wistar Rats) ผู้เขียน:Wanwarang Watcharananun, Songpol Chivapat, Anudep Rangsripipat, Aimmanas Attawish, Pranee Chavalittumrong, Songpol Padungpat, Tongchai Puttongsiri, Kittipong Hungrak สื่อสิ่งพิมพ์:pdf AbstractLiquid smoke (LS) from ‘Tian Op ’ has been developed for ‘feathering’ (softening) the odor of many Thai desserts. The benefi ts of liquid smoke are reduced smoking time, increased ease of utilization and standardization of the intensity of the fl avor in dessert products. The Medicinal Plant Research Institute, Department of Medical Science, Ministry of Public Health, Thailand conducted a 90 d oral subchronic toxicity test of LS in 120 Wistar rats divided into fi ve groups (12 per sex per group). Groups 1 and 2 were control groups receiving distilled water and propylene glycol at a volume of 10 mL.kg-1. day-1, respectively, where the weight was based on live body weight. Groups 3–5 were experimental groups receiving LS at doses of 0.04, 0.4 and 4.0 g.kg-1.day-1, respectively. LS at any dosage did not affect growth, food consumption and hematological values. Rats receiving LS at doses of 0.4 and 4.0 mL.kg-1.day-1 had signifi cantly higher albumin levels than the water control and the propylene glycoltreated rats, but these alterations did not indicate any abnormalities. Histopathology of organs revealed no abnormalities related to liquid smoke toxicity. Therefore, it may be concluded that liquid smoke at the given dosages did not produce toxicity in Wistar rats. |
