Effects of overexpression of PnSS gene from Panax notoginseng on tobacco terpenoid contents and plant growth and development
Nicotiana tabacum solanesyl diphosphate synthase 1 (NtSPS1) is the key enzyme in solanesol biosynthesis. However, changes in the solanesol content, plant growth, photosynthesis, and metabolome of tobacco plants after NtSPS1 overexpression (OE) have not been previously reported. In the present study, these parameters, as well as photosynthetic gas exchange, chlorophyll content, and chlorophyll fluorescence parameters, were compared between NtSPS1 OE and wild type (WT) lines of tobacco. As expected, NtSPS1 OE significantly increased solanesol content in tobacco leaves. Although NtSPS1 OE sign
Air flow distribution in a lit cigarette during puffing
Establishing a realistic gas flow velocity distribution inside a cigarette filter during smoking is important to understand filtration mechanisms of different mainstream smoke species and the overall effect of filter designs on mainstream smoke composition. In this paper, an experimental method is described which directly measures the gas pressure field inside a cellulose acetate filter during cigarette smoking. This was demonstrated by using 3R4F research reference cigarettes smoked under a 35 mL puff of 6 s duration. In addition, filter temperature measurements were also carried out at mu
Migration characteristics of moisture and glycerol in cut tobacco strips during pneumatic drying
Drying is a technique that involves removal of moisture using heat energy. This heat affects the protein components in foods especially the thiosulphide groups, which causes hydrophobic bond break that has been attributed greatly to denaturation during drying. Safe moisture content (SMC) is the extent to which moisture can be withdrawn from food crops during drying that such crops can be considered safe for storage with minimal loss of nutritional qualities. Several reported minimum moisture contents, and bulk nutrients’ levels of crops were collected for the purpose of this review, a
Pipe tobacco sensory quality index evaluation based on internet sourced data
The invention discloses a sensory quality evaluation method directing at an electronic cigarette. According to the sensory quality evaluation method, seven sensory evaluation indexes which are respectively fragrance, strength, concentration, harmony, miscellaneous qi, irritation and remaining taste are supplied; no less than 7 smoke evaluation persons participate in evaluation; an overall circulation smoke evaluation method is adopted; and a nine-mark scoring method is adopted for the sensory evaluation indexes. The sensory quality evaluation method fills up the blank of sensory evaluation
Optimized design of tobacco flavoring cylinder based on discrete element method
In order to solve the problems of poor flavoring uniformity, low flavor absorption rate and external environment pollution caused by the unreasonable design of the flavoring machine, based on the discrete element method, the EDEM simulation software was used to simulate the throwing characteristics of the flavoring machine drum. The number and structure of flight boards, drum speed and spraying device were optimized under the number of flight boards and the rotating speed of the drum. The SJ236B flavoring machine produced by Kunming Ship Equipment Group Co., Ltd. was used as the object, and
Design and application of robot for tobacco basket cleaning
In order to solve the problem of waste of tobacco leaves caused by excessive tobacco leaves adhering in the tobacco baskets after turning over and dumping materials in the vacuum resurfacing section of the silk production line, an automatic cleaning robot for tobacco baskets was designed, which consisted of a six-axis manipulator, a visual inspection system and a cleaning device. .Sine function is used to improve the S-shaped curve trajectory planning to ensure the smooth movement of the six-axis manipulator, avoiding vibration and impact of the cleaning robot; using the visual inspection s
Detection of Bacillus cereus in cigar tobacco leaves using COMPASS and MYP media
In order to explore a rapid and accurate method suitable for the detection of Bacillus cereus in cigar leaves, the performances of the COMPASS chromogenic medium method (COMPASS method) and ISO 7932 were compared. The results showed that: The standard strain was used The properties of COMPASS chromogenic medium and ISO 7932 method using mannitol egg yolk polymyxin agar (MYP) medium were respectively verified with quantitative quality control strains. The specificity and selectivity of COMPASS chromogenic medium were better, and the sensitivity was comparable to ISO The 7932 method was compa
Analysis and evaluation of activated ceramic ball-treated water and its application to cigarette production
The Ceramic water filtration has been greatly improving the most waste materials from drinking water in developing countries. This research was carried out to determine the efficiency of the Ceramic water filters in improving water impurities. The raw materials were grind, sieved with 0.5 mm opening mush size, mixed with water, molded in flower pot shape and fired at 700 °C, 750 °C and 800 °C. The average removing efficiency of the ceramic filters was found to be 59.6%, 86.3%, 87.6%, 56.9%, 59.02%, 88.98%,76.2%, 52.88%, 46.23% and 226.66 m L/h for turbidity, total coliform, E. c
Efficacies and residue levels of insecticides applied by electrostatic and electric sprayers in tobacco fields
In order to realize the effective monitoring and early warning of potato virus Y (PVY) disease by means of spectral analysis, the spectral data of infected tobacco leaves with different severities were obtained by using ASD non-imaging spectrometer. increased, the spectral reflectance of leaves showed a gradually increasing trend in the visible light band (400-700 nm), and a gradually decreasing trend in the near-infrared band (700-1300 nm). The severity of Y virus disease was significantly correlated with the wavelength, and based on the spectral reflectance of the sensitive wavelengths 45
