Problems solved by technology

In addition, different personnel have inconsistent grasps of the difference in appearance color and uniformity, and it is easy to have differences and differences in the judgment of the inspection results, and even misjudgment.
The existence of this judgment difference is not conducive to the production control of products and the judgment and acceptance in trade. In order to realize the scientific and effective judgment standard and meet the actual needs of enterprises, it is urgent to establish a method that can quantify the appearance color of reconstituted tobacco leaves by papermaking method. Method of Chemical Detection and Judgment

Embodiment

[0038] Paper-making reconstituted tobacco leaf product models A, B, and C all have a packaging specification of 50kg, and the total products of the three models are 35 tons, 42 tons, and 37.5 tons, respectively. 10 boxes of each model were randomly unpacked, 200 grams were sampled from each box, and the samples taken from the 10 boxes were combined into a total sample of about 2kg. Fully mix the 2kg sample evenly, randomly extract 100 grams from the 2kg sample, and obtain 100 grams each of 3 types of samples to be tested, and set aside.

[0039] Take out 100 grams at random from the standard samples of the three products of product model A, model B and model C for later use.

[0040] Spread the three types of samples to be tested and the corresponding standard samples of the same type on 6 white porcelain plates, and first adjust the constant temperature and humidity chamber so that the temperature is 22±1°C and the relative humidity is 60±2%. , after the temperature and humi...

Abstract

The invention discloses a paper-making method recreated tobacco leaf appearance color detection method, The sample color uniformity is presented by the absolute value of the difference between the single-piece sample measurement value and the mean value and the color difference of the sample to be tested is represented by the absolute value of the difference between the sample lightness value mean value, the mean value of the red and green value, the mean value of the yellow and blue value and the standard measurement value. If two or more color uniformity index values do not accord with the specification: Delta Ln<=2.0, Delta a n<=1.5, Delta bn <=1.5, thus the color uniformity is unqualified. If one or more color differential values do not accord with the specification: DeltaL<=2.5,Deltaa<=1.5,Deltab<=1.5, thus the color difference is unqualified. The said method can effectively prevent the misjudgement due to the human factor of the sense organ, thus the appearance color index is changed into quantified data index from qualitative description, therefore the accuracy and consistency of the judgement can be ensured.

Description

technical field [0001] The invention belongs to the technical field of cigarette evaluation, and in particular relates to a method for detecting the appearance color of reconstituted tobacco leaves by a papermaking method. Background technique [0002] YC / T16.3-2003 "Reconstituted Tobacco Leaf Part 3: Papermaking Method" standard describes the sensory quality and color of reconstituted tobacco leaves as follows: the color is uniform, and the color is consistent with the standard sample specified in the contract. When detecting and judging the appearance color of reconstituted tobacco leaves by the papermaking method, the prior art all relies on personal sensory evaluation, that is, using the specified standard sample and the sample to be tested for visual sensory evaluation; Consistent means that the sample to be tested meets the requirements. The appearance color index of papermaking reconstituted tobacco leaves is inspected with naked eyes as the only basis for whether th...
