Method and application for extracting tobacco use spice from corn cob

Abstract

The invention discloses a method and application for extracting tobacco use spice from corn cobs, which belong to the field of preparation and application of tobacco spice in the cigarette technology. The method comprises the following steps: (1) crushing the corn cobs into a pressure vessel and holding the corn cobs in the pressure vessel at a room temperature and under 3MP for 3 to 15 minutes; (2) setting the proportion of the corn cobs: 50 to 95 percent ethanol equal to 1: (5-10), setting the extracting temperature at 75 to 90 DEG C and the extracting time 0.5 to 4 hours; (3) concentrating the mixture to the density of 1.0317; and (4) refrigerating the mixture at 2 DEG C below zero to 2 DEG C and obtaining the corn cob extract after filtering. The corn cob extract is added into tobacco shreds for perfuming according to a proportion of 0.06 to 0.1 percent; or the corn cob extract is added into a tobacco use spice recipe according to a proportion of 0.02 to 2 percent and then the perfuming is carried out. The method is simple and practical and is easily carried out; and the method has high extracting yield. The corn cob extract has the effects of softening the tobacco gas, refining the tobacco flavor and promoting flavor emission.

Description

technical field [0001] The invention belongs to the field of preparation and application of tobacco spices in cigarette technology, and in particular relates to a method for extracting tobacco spices from corn cobs by using plant wall breaking technology, and the application of the extracted tobacco spices in cigarettes. Background technique [0002] Corncob is the cob of the corn fruit of the grass plant. The sown area of ​​corn in the world ranks third after wheat and rice. China's corn production ranks second in the world, and it is the main food crop after wheat. Its planting area and production rank first in autumn grain crops. In our country, the existing 93 million hm 2 Among the cultivated land, the area of ​​corn is about 21 million hm 2 , accounting for 1 / 5 of the total cultivated land area. Corn production is 110-130 million tons per year, and 20 million tons of corn cobs can be produced. However, as a kind of agricultural waste, corncobs cannot be widely use...

AI Technical Summary

Problems solved by technology

At present, the extraction of commonly used natural spices is generally by crushing the natural raw materials first, and then extracting them through solvent reflux, steam distillation and other methods. These extraction methods are relatively mature technologies, but they all have low extraction efficiency and damage during heating. Disadvantages such as high loss of active ingredients and volatile active substances

Among them, the most serious problem is that the active ingredients are difficult to leach from the plant cell wall, resulting in excessive material ratio, low yield, and many impurities, which have a significant impact on production and quality.
