Problems solved by technology

Under the condition of hot air circulation in the normal baking process, increase the yellowing temperature, fix the temperature and keep the moisture in the three periods of leaf yellowing, gluten period, and dry leaf period, extend the baking time three times, and the delay time is 42-60 Hours, promote the decomposition of macromolecular substances such as tobacco leaf starch, and reduce the tobacco leaf starch after roasting. However, in the season when tobacco leaves are harvested and roasted, the single kang baking cycle is too long, which will increase fuel consumption and increase the impact on the environment. Pollution
This curing method does not change the structure of tobacco leaves and the essence of the original three-stage curing process, and it also cannot achieve the purpose of shortening the total duration of single kang curing and reducing starch while fully extending the yellowing period and color fixing period.

Embodiment 1

[0029] Embodiment 1, "half-leaf" baking method reduces the starch content test of tobacco leaves (Hubei)

[0030] The content of starch in the upper part of the tobacco is relatively high, and the "half-leaf" baking is used to investigate the effect on reducing starch.

[0031] Materials and Methods:

[0032] 1.1 Test location: Xiaoguan Town, Xuanen County, Enshi City, Hubei Province

[0033] 1.2 Test materials: Yunyan 87, upper smoke

[0034] 1.3. Processing settings:

[0035] Baking in a downdraft oven with three treatments:

[0036] The complete leaf is along the side of the main tobacco rib, close to the main tobacco rib to divide a complete leaf into two, and bake it on a specially designed special tobacco rod hanging rod, with one side without ribs (treatment 1) and the other side with ribs (treatment 2) ). Conventional whole leaf binding roast (for treatment three).

[0037] Namely: Treatment 1: A1━half leaf is roasted without ribs, and half tobacco leaf is dried;...

Embodiment 2

[0062] Example 2. Test of reducing the starch content of tobacco leaves by "half-leaf" baking method (Jia County, Henan Province)

[0063] 1 Materials and methods:

[0064] 1.1 Test site: Ningxian Songkang House, Jia County, Pingdingshan, Henan Province

[0065] 1.2 Test materials: medium smoke 100, upper smoke

[0066] 1.3. Processing settings:

[0067] Baking in a downdraft oven with three treatments:

[0068] The complete leaf is along the side of the main tobacco rib, close to the main tobacco rib to divide a complete leaf into two, and bake it on a specially designed special tobacco rod hanging rod, with one side without ribs (treatment 1) and the other side with ribs (treatment 2) ). Conventional whole leaf binding roast (for treatment three).

[0069] Namely: Treatment 1: A2━half leaf is roasted without ribs, and half tobacco leaf is dried; the roasting is terminated;

[0070] Treatment 2: B2━Roasting half leaves with tendons;

[0071] Treatment 3: C2━conventiona...

Abstract

The invention relates to a half-leaf curing method for reducing starch content of flue-cured tobacco. According to the method, a half-leaf harvesting mode is adopted, two half tobacco leaves without tobacco stems are put on rods, the rods are put into heating beds for curing; and the curing process only comprises the three stages, namely, a leaf yellowing stage, a leaf withering and branch vein yellowing stage and a leaf delayed color fixing stage. By means of the tobacco leaf curing method provided by the invention, the starch content of the cured tobacco leaves can be obviously reduced, the irritation of the cured tobacco leaves during smoking can be reduced, and the comfort of the aftertaste of the tobacco leaves during smoking can be improved; a stem drying stage is omitted, the total time of single-heating bed curing can be shortened under the condition that the yellowing stage and the color fixing stage are fully prolonged, and precious curing season resources are saved; the curing time is obviously shortened, a large amount of curing fuel consumption is saved, and air pollution of fuel to the environment is reduced; only the leaves are cured in a curing barn, the occupied space of the curing barn is small, and the tobacco loading capacity of a single heating bed is greatly improved; half-leaf curing does not contain tobacco stems, and the cured tobacco leaves do not need to be threshed.

Description

technical field [0001] The invention belongs to the technical field of harvesting and modulation of fresh flue-cured tobacco leaves, in particular to a "half-leaf" roasting method for reducing the starch content of flue-cured tobacco, and relates to a fresh tobacco harvesting hanger and a matching roasting method for reducing the starch content of cured tobacco leaves in dense curing rooms . Background technique [0002] Starch generally contains about 25-40% in fresh tobacco leaves. It is an important basic carbohydrate in tobacco leaves. The soluble sugars and reducing sugars degraded and transformed during the roasting process, and the acidic products produced by the lysates during smoking have a negative impact on the balance caused by the tobacco leaves. Alkaline fumes produced during smoking of bases and nitrogenous compounds have a positive effect. Under the condition of C / N balance in the cured tobacco leaves, the lower the starch content in the tobacco leaves, the ...
