Abstract

The invention relates to a cigarette essence quality detection method. According to the method, a colorimeter is adopted to detect values L, a and b of a cigarette essence standard substance and values L, a and b of a to-be-detected sample; the values L, a and b of the to-be-detected sample are compared with the values L, a and b of the standard substance, and delta(L), delta(a), delta(b) and delta(E) are obtained; a near-infrared spectrometer is adopted to collect a spectrum of the cigarette essence standard substance and a spectrum of the to-be-detected sample, and the collected spectra arepretreated to eliminate noise and correct baselines; in combination with a Gram-Schmidt orthogonalization method, the cigarette essence standard substance is selected to serve as a standard, and the similarity between the cigarette essence to-be-detected sample and the standard substance is calculated; and when the cigarette essence to-be-detected sample meets the relations that the delta(E) is smaller than or equal to 1.0, the similarity n is greater than or equal to 90%, and absolute values of the delta(L), the delta(a) and the delta(b) are all smaller than or equal to 0.5, the detected cigarette essence to-be-detected sample is qualified. The method is objective, easy and convenient to implement, accurate in calculation result, fast in detection process and easy to apply and popularize.

Description

technical field

[0001] The invention belongs to the technical field of flavoring essence for tobacco, and specifically relates to a method for detecting the quality of flavoring essence for tobacco by using color difference analysis technology and near-infrared spectrum analysis technology in combination with color difference and similarity. Background technique

[0002] Tobacco essence is an important component in the process of flavoring cigarettes, which determines the aroma and aroma of cigarettes. In the cigarette industry, the quality control of tobacco flavors is mainly guided by the industry standard "YC / T 164-2012 Tobacco Flavors", but there are many testing items in this standard, and the testing time is long; some testing items are also subjective. (such as: appearance, miscibility, aroma quality, aroma quality), and in the standard "judgment and re-inspection rules", the above four indicators can be used as important indicators for single-item judgment. Therefor...

Examples

Embodiment 1

[0045] Embodiment 1: the quality detection of the flavoring essence for tobacco of same raw material, process condition and product name

[0046] (1) A in this embodiment 0 The sample is a standard product of tobacco flavor, A 1 ~A 5 The samples are different batches of samples to be tested, and the samples in this group are all tobacco absolute samples.

[0047] (2) adopting instrument and software in the embodiment are: Color i7 colorimeter (U.S. X-Rite company); Nicolet is50 near-infrared spectrometer (U.S. Thermo Scientific company), with integrating sphere diffuse reflectance attachment, OMNIC near-infrared spectrometer operating software ( American Thermo Scientific Company).

[0048] (3) Use a colorimeter to perform specific operations on the tobacco flavor sample as follows:

[0049] a. Turn on the instrument, computer and other accessories, and preheat the instrument for 60 minutes;

[0050] b. Open the corresponding operating software in the computer to complete...

Embodiment 2

[0069] Embodiment 2: Quality detection of flavoring essence for tobacco with the same product name under different raw materials and process conditions

[0070] (1) repeat embodiment 1, have following difference:

[0071] a. B in this example 0 ~B 3 It is a group, and the samples in this group are loquat absolute samples, where B 0 The sample is a standard product of tobacco flavor, B 1 The sample is A a Samples provided by the manufacturer, B 2 The sample is A b Samples provided by the manufacturer, B 3 The sample is A c Samples provided by the manufacturer.

[0072] b. In this example C 0 ~C 3 is a group, and the samples in this group are all tobacco extract samples, where C 0 The sample is a standard product of tobacco flavor, C 1 sample for B a Samples provided by the manufacturer, C 2 sample for B b Samples provided by the manufacturer, C 3 sample for B c Samples provided by the manufacturer. In this group of embodiments, it can be used as a comparison w...
