Embodiment 1

[0059] Example 1 Extraction and Purification of Luffa Polysaccharide

[0060] The extraction and purification of luffa polysaccharide of the present embodiment comprises the following steps:

[0061] Take fresh loofah, dry naturally under the sun, crush, and pass through a 60-mesh sieve to obtain loofah powder. Get the solvent of 80 times of parts by weight of loofah powder in an appropriate amount. After mixing evenly, ultrasonic wave 300w, 30 ℃ for 10min. Heated at 60°C and extracted twice with shaking. High-speed large centrifuge 8000r / s, centrifuge at 4°C for 30min. The obtained loofah supernatant was concentrated under reduced pressure to 1 / 3 of the original volume. Add 95% ethanol until the concentration of ethanol is 80%, let it stand for 24 hours, and centrifuge again to obtain crude polysaccharide from loofah. The yield of polysaccharide determined by phenol sulfuric acid method is 3.20%.

[0062] The precipitate was repeatedly washed 2-3 times with acetone. The...

[0063] Example 2 Extraction and Purification of Luffa Polysaccharide

[0064] The extraction and purification of luffa polysaccharide of the present embodiment comprises the following steps:

[0065] Take fresh loofah, dry it naturally under the sun, crush it, and pass through an 80-mesh sieve to obtain loofah powder. Get the solvent of 60 times of parts by weight of loofah powder in an appropriate amount. After mixing evenly, ultrasonic treatment at 100w, 20°C for 20min. Heated at 50°C and extracted twice with shaking. High-speed large centrifuge 10000r / s, centrifuge at 4°C for 20min. The obtained loofah supernatant was concentrated under reduced pressure to 1 / 2 of the original volume. Add 95% ethanol until the concentration of ethanol is 70%, let it stand for 20 hours, and centrifuge again to obtain the crude polysaccharide of loofah. The yield of polysaccharide determined by phenol-sulfuric acid method is 2.98%.

[0067] Example 3 Extraction and Purification of Luffa Polysaccharide

[0068] The extraction and purification of luffa polysaccharide of the present embodiment comprises the following steps:

[0069] Take fresh loofah, dry it naturally under the sun, crush it, and pass it through a 100-mesh sieve to get loofah powder. Get the solvent of 200 times of parts by weight of loofah powder in an appropriate amount. After mixing evenly, ultrasonic treatment at 200w, 25°C for 5min. Heat at 80°C and shake to extract once. High-speed large-scale centrifuge 12000r / s, centrifuge at 4°C for 10min. The obtained loofah supernatant was concentrated under reduced pressure to 1 / 3 of the original volume. Add 95% ethanol until the concentration of ethanol is 60%, let it stand for 22 hours, and centrifuge again to obtain crude polysaccharide from loofah. The yield of polysaccharide determined by phenol sulfuric acid method is 3.63%.

Abstract

The invention relates to the technical field of tobacco processing, and in particular to an application of luffa polysaccharide as well as a tobacco humectant and a humidify preserving method. As forthe application, the luffa polysaccharide is used for preparing the tobacco humectant. With the application of an extracting and refining method, the refined luffa polysaccharide, which is high in purity, is obtained; the refined luffa polysaccharide is dissolved in water and obtained liquid is sprayed onto tobacco shreds; and based upon physical humidity preserving performance test and sensory quality evaluation, it is discovered that prepared cigarettes are relatively good in humidity preserving effect, irritation and offensive odor of the cigarettes are reduced and humectant and comfort ofthe cigarettes are enhanced.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to an application of luffa polysaccharide, a tobacco moisturizing agent and a moisturizing method. Background technique [0002] With the development of Chinese-style cigarettes, the technology of increasing flavor and keeping moisture has become a technical problem to be solved urgently in the tobacco industry. In cigarette production, adding humectants can improve product quality, reduce crushing during processing, improve the physical properties of tobacco, and increase its processing resistance. There are a large number of capillary porous bodies in the tissue structure of tobacco, which has high surface energy. Its chemical composition contains colloidal substances such as pectin and water-soluble sugars. It uses the abundant hydroxyl groups of plant polysaccharides to form hydrogen bonds with the substances in tobacco to achieve moisture retention. Purpose. [000...
