Description

Technical Field

[0001] The present invention relates to tobacco processing, and more particularly to a method for enhancing the floral and fruity aroma of cigars by curing with a blended alcohol curing solution. Background Art

[0002] After cigars are rolled into tobacco leaves through agricultural and industrial fermentation, they need to be cured. This curing process involves adjusting the temperature, humidity, and the use of curing media to achieve aging. This aging process significantly reduces odors, improves the mellowness of the tobacco, and enhances its quality. Conventional curing methods typically involve neatly placing finished cigars in humidors or humidor cabinets, maintaining them at standard temperature and humidity conditions, and allowing for a flexible curing time.

[0003] Cinnamomum camphora (Lauraceae) belongs to the Lauraceae family. Its leaves are rich in nutrients such as various amino acids, polyphenols, and vitamins. They are high in free amino acids and soluble sugars, which can promote metabolism, alleviate fatigue, enhance immunity, and prevent various diseases. The inventors have discovered that adding Cinnamomum camphora leaf extract to the curing process of cigars can effectively enhance the aroma richness of the tobacco leaves, modifying the smoke, reducing irritation, and enhancing the floral and fruity notes of the tobacco leaves. Summary of the Invention

[0004] The present invention overcomes the shortcomings of the prior art and provides an embodiment of a method for enhancing the fruity aroma of cigars by curing with a blended alcohol curing solution. The method comprises the following steps: curing with a Cinnamomum camphora leaf extract, potassium cinnamate, and glycerol to enhance the richness of the tobacco leaf aroma, modify the smoke to reduce irritation, and enhance the fruity and floral aroma of the tobacco leaf; and at the same time, effectively prolonging the shelf life and maintaining moisture.

[0005] In order to solve the above technical problems, one embodiment of the present invention adopts the following technical solutions:

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] Preparation Example 1 of Curing Alcohol Solution

[0022] Step 1: Take fresh leopard skin camphor tree leaves and stir-fry them. After stir-frying over medium-low heat, grind them in a mortar and pass them through a 50-mesh sieve to remove large particles. The sieved powder is set aside for later use. An extraction solvent (95% ethanol) is added at a ratio of 1:1 (w / w). After shaking on an oscillator at 500 Hz / min for 120 minutes, the mixture is placed in a high-speed centrifuge and centrifuged at 20,000 rpm for 10 minutes. The upper layer of oily extract is set aside for later use.

[0023] Step 2: dilute the oily extract with 30% ethanol at a dilution ratio of 1:1 (w / w), and simultaneously add 1% glycerol and 1‰ potassium cinnamate powder to the solution to prepare an alcohol curing solution for curing cigars; used in Example 1.

[0024] Preparation Example 2 of Curing Alcohol Solution

[0025] Step 1: Take fresh leopard skin camphor tree leaves and stir-fry them. After stir-frying over medium-low heat, grind them in a mortar and pass them through a 50-mesh sieve to remove large particles. The sieved powder is set aside for later use. An extraction solvent (95% ethanol) is added at a ratio of 1:5 (w / w). After shaking on an oscillator at 800 Hz / min for 120 minutes, the mixture is placed in a high-speed centrifuge and centrifuged at 30,000 rpm for 10 minutes. The upper layer of oily extract is taken for later use;

[0026] Step 2: dilute the oily extract with 35% ethanol at a dilution ratio of 1:5 (w / w), and simultaneously add 5% glycerol and 5‰ potassium cinnamate powder to the solution to prepare an alcohol curing solution for curing cigars; used in Examples 2 and 3.

[0027] Example 1:

[0028] Prepare 10 finished Great Wall Legend No. 1 cigars, add curing alcohol solution to the circulating moisturizing system of a cigar curing cabinet as a humidity adjustment solution, and place the cigars in the cigar curing cabinet for curing at a temperature of 20±1°C and a relative humidity of 75% for 30 days.

[0029] In addition, the maintenance alcohol solution was replaced with pure water, and a blank control group experiment was carried out according to the same steps.

[0030] The sensory quality evaluation method or standard for cigar tobacco leaves is the "Sensory Evaluation of Cigar Style Characteristics".

[0031] The operation of aroma component detection is as follows:

[0032] Sample preparation: Approximately 1 g of crushed tobacco leaf sample was placed in a 22 mL headspace vial, sealed with a cap, and extracted using a manual solid-phase microextraction (SPME) device. An automated headspace solid-phase microextraction (HS-SPME) device equipped with a 50 / 30 μm DVB / CAR / PDMS fiber was exposed to the headspace of the sample vial. Extraction was performed at 60°C for 30 min at a needle speed of 20 mm / s. Following extraction, desorption was performed on a GC analyzer at 250°C in splitless mode for 1 min, and volatile compounds were determined by gas chromatography-mass spectrometry (GC-MS).

[0033] GC conditions: RTX-waxMS column, flow rate 1.0 mL / min, helium as carrier gas, inlet temperature 250°C. Temperature program: 60°C for 2 min, initially at 10°C / min to 110°C, then at 3°C / min to 150°C, and finally at 15°C / min to 230°C, where the temperature was held for 20 min.

[0034] MS conditions: electron impact ion source (EI), ion source temperature 230°C, quadrupole temperature 150°C, transfer line temperature 230°C; electron energy: 70 eV, electron multiplier voltage: 1500 V; scanning mass range: 45-350 m / z.

[0035] The identification of volatile compounds was based on comparative analysis between the computer spectral libraries WILEY 8.0 and NIST 14. Only identification results with a positive and negative similarity greater than 800 were reported. The relative content was calculated using the area normalization method.

[0036] The same evaluation method or detection method was used for the embodiment and the control group.

[0037] The evaluation and test results are shown in Tables 1 and 2.

[0042]

[0043]

[0044] The aroma components and sensory evaluation results of the aforementioned cigar samples indicate that curing Great Wall Legend No. 1 with the blended alcohol solution increases the levels of common aroma components found in cigar tobacco, such as solanone, dihydroactinol, megastigmatrienone, and neophytadiene. These substances help reduce irritation and increase both the quality and volume of the aroma. The presence of linalool oxide (furan type), tea ketone, and 1-phenyl-1,2-propanedione, which are present in high concentrations in the blended alcohol solution, imparts a floral and fruity aroma to the tobacco.
