A tobacco flavor was prepared with Maillard reaction method from the flower buds of burley tobacco, the reaction product was treated by simultaneous distillation and extraction method, then the volatile components in the reaction product were analyzed by GC/MS. The results showed that: 1) Thirty-four volatile components, including two esters, five terpenes, ten alcohols, two aldehydes, one acid, eight ketones, one phenol, and five nitrogen heterocyclic compounds, were detected. 2) Comparing with the volatile components in the product by direct extraction, four Maillard style flavor compounds were special in the product by MaiUard reaction, namely dihydroxyacetone, 2-methyltetrahydrofuran-3-one, 2-acetylfuran and phenylacetone. Sensory evaluation indicated that the flavor prepared with MaiUard reaction featured better aroma quality with a slight smell of flower, enhanced sweetness and smoothness, and offered a pleasurable aftertaste. ©, 2014, Editorial Office of Tobacco Science and Technology.

A novel method, termed ionic liquid-based hollow fibre liquid phase microextraction (IL-HF-PLME), coupled with high-performance liquid chromatography (HPLC) was developed for separation and preconcentration of three phthalate esters (PAEs) in tea beverage. In the present study, ionic liquid 1-butyl-3-methy-limidazolium hexafluorophosphate ([BMIm]PF6) was placed in the porous-walled polypropylene hollow fibre as the acceptor phase, and nonanol was used as the supported liquid membrane phase that accomplished extraction. Several important parameters influencing the extraction efficiency were investigated in detail. Under the optimized conditions, good linearity occurred in the range of 5-1000 ng mL-1 with the correlation coefficients values above 0.998. The limits of detection ranged from 0.67 to 1.73 ng mL-1. Recoveries of three PAEs in two kinds of spiked tea beverage samples (PAEs, 10.0-100.0 ng mL) were between 94.2 and 103.4%, with relative standard deviations (RSDs) ranged from 1.77 to 3.02%. The enrichment factors were 200. The developed IL-HF-PLME method allowed the simple, rapid, and sensitive determination of phthalate esters in tea beverage samples with an extraction time of just 4 min. © 2016 Elsevier Ltd.

Background. Excessive manganese exposure induced cognitive deficit. Several lines of evidence have demonstrated that taurine improves cognitive impairment induced by numerous neurotoxins. However, the role of taurine on manganese-induced damages in learning and memory is still elusive. This goal of this study was to investigate the beneficial effect of taurine on learning and memory capacity impairment by manganese exposure in an animal model. Results: The escape latency in the Morris Water Maze test was significantly longer in the rats injected with manganese than that in the rats received both taurine and manganese. Similarly, the probe trial showed that the annulus crossings were significantly greater in the taurine plus manganese treated rats than those in the manganese-treated rats. However, the blood level of manganese was not altered by the taurine treatment. Interestingly, the exposure of manganese led to a significant increase in the acetylcholinesterase activity and an evidently decrease in the choline acetyltransferase activity, which were partially restored by the addition of taurine. Additionally, we identified 9 differentially expressed proteins between the rat hippocampus treated by manganese and the control or the manganese plus taurine in the proteomic analysis using the 2-dimensional gel electrophoresis followed by the tandem mass spectrometry (MS/MS). Most of these proteins play a role in energy metabolism, oxidative stress, inflammation, and neuron synapse. Conclusions: In summary, taurine restores the activity of AChE and ChAT, which are critical for the regulation of acetylcholine. We have identified seven differentially expressed proteins specifically induced by manganese and two proteins induced by taurine from the rat hippocampus. Our results support that taurine improves the impaired learning and memory ability caused by excessive exposure of manganese. © 2014 Lu et al.; licensee BioMed Central Ltd.

In order to monitor crop planting area and predict its production, HJ-1 satellite (No.1 Environment satellite union of A and B) remote sensing data were used to analyze the spectral reflection characteristics of flue-cured tobacco crop and other ground objects. Three vegetation indices, including normalized difference vegetation index (NDVI), difference vegetation index (DVI) and ratio vegetation index (RVI), were calculated and their discrimination of flue-cured tobacco from other ground objects was analyzed and compared. The method for recognition of flue-cured tobacco from remote sensing data was determined, and the planting information of flue-cured tobacco in Jingxi County, Guangxi was extracted with the developed method. The method precision was verified with GPS field sampling data, and the obtained total precision was 92.79% with Kappa coefficient of 0.8374. It suggested that remote sensing technology could be used to obtain tobacco planting information quickly and accurately.

To solve the problems of low efficiency and frequent zero drift in running the tobacco case opener in the tobacco primary processing line, the control system in the machine was improved as following: 1) Installing three proximity switches for position monitoring and adding position signal feedback in PLC control program to correct the rotational position of manipulators and avoid zero drift. 2) Optimizing case opening sequences to enable multiple case opening actions simultaneously. 3) Adding zero searching function in the control program, starting zero searching program automatically in the event of zero drift. The results of application showed that after improvement, the frequency of zero drift reduced obviously, the failure rate of case opener decreased from 13.3% to 1.9%, it only took three minutes to search zero, and the time for case opening reduced from two minutes/case to forty-five seconds/case.

Tobacco Warehousing is chiefly applied to preserve the tobacco that is separated into leaf and stem so that the tobacco moisture is controlled at the range of technology demand.The present control method of tobacco save is that the references of every PID control link are set up and adjusted by human experience. So, the control effect varies with the individual and the output tobacco moisture can't maintain stable.The fuzzy-PID temperature system is based on CC2430 single chip. It includes the power source, the manipulative algorithm, the temperature examination, the correspondence of up PC and the output-control of the switch value and so on. Computer takes the parameter deviation and the deviation change as input, and the PID controller's parameters of ΔKp, Δki, ΔKd as output. The sub program realized the corresponding events by completing zone bit and zone bit judgment. The main program realized temperature control function by calling the wireless micro-controller sends a signal to the charged unit. © (2013) Trans Tech Publications, Switzerland.
