Embodiment 1

[0019] Take dried hollyhock rhizomes, remove impurities, crush them, and weigh them; add 12 times the mass of water (distilled water, purified water or deionized water is acceptable), soak at room temperature for 3 hours, heat up to 50°C, and add dry hollyhock root powder Cellulase with 1% mass and 0.3% protease were kept at 50°C for 3 h; then heated to 90°C and refluxed for 3 h; after heating was stopped, the feed liquid was cooled to room temperature and centrifuged at 2000 rpm for 40 min; the supernatant was Concentrate under reduced pressure to a paste content of 10% to obtain the water extract of marshmallow rhizome.

[0020] Weigh 0.005 g of the above-mentioned hollyhock rhizome aqueous extract, add distilled water to 5.000 g, mix well, and spray evenly on 100 g of blank shredded tobacco with a micro sprayer (addition amount is 0.05 ‰). Put the shredded tobacco into a sealed bag, place it in an oven at a constant temperature of 80°C for 30 minutes, then shake the shredde...

Embodiment 2

[0022] The dried hollyhock root powder was obtained by removing impurities, drying, and pulverizing the hollyhock root, adding 15 times the mass of water, soaking at room temperature for 2 hours, heating to 45°C, adding 0.5% cellulase and 0.4% Protease, kept at 45°C for 2 h; then heated to 75°C and refluxed for 5 h, stopped heating, cooled to room temperature, and centrifuged at 4000 rpm for 30 min; concentrated under reduced pressure to a paste content of 20%. Aqueous extract of marshmallow root.

[0023] Weigh 0.020 g of marshmallow root aqueous extract, add distilled water to dilute to 1.000 g, mix well, inject 4 μL into each blank cigarette with a cigarette flavoring injection machine (flavoring amount is 0.1 ‰); take another part of blank cigarettes, Each cigarette was injected with 4 μL of distilled water as a control cigarette. The flavored cigarettes and control cigarettes were placed in constant temperature (22±1°C) and constant humidity (relative humidity 60±2%) cha...

Embodiment 3

[0025] The hollyhock stems were weighed after removing impurities, drying, crushing, adding 10 times the mass of water, and soaking at room temperature for 4 hours; after heating to 55°C, adding 1.5% cellulase and 0.2% protease in the dry powder of hollyhock stems , keep the temperature at 55°C for 1.5 h; then heat up to 80°C and reflux for 4 h, stop heating, wait for the feed liquid to cool to room temperature, filter under reduced pressure, vacuum degree -0.08 MPa, the clear liquid is concentrated under reduced pressure to a paste content of 30 % to obtain the water extract of hollyhock stems.

[0026] Weigh 0.100 g of the above hollyhock stem aqueous extract, dilute to 10.000 g with distilled water, and mix well. Take two equal parts of shredded tobacco, one of which is evenly sprayed on the shredded tobacco with a diluted solution of hollyhock flower water extract (the amount of flavoring is 0.5 ‰) according to 5% of the weight of shredded tobacco; the other is evenly spra...

Abstract

The invention relates to a preparation method of a hollyhock root / stem water extract, which is characterized by comprising the following steps: drying the hollyhock root and / or stem, removing impurities, pulverizing, adding water, immersing, carrying out enzymolysis reaction, heating for extraction, carrying out solid-liquid separation, and concentrating under reduced pressure to obtain the hollyhock root / stem water extract. The obtained hollyhock root / stem water extract is a yellow brown liquid; after the hollyhock root / stem water extract is diluted with water and applied to cigarette cut tobacco, the flue gas does not have peculiar smell when the cigarette is smoked; and thus, the hollyhock root / stem water extract can enrich the scent, improve the aroma quality, increase the sweetness and wetness, lower the dry sensation and enhance the oral comfort. The hollyhock root / stem water extract is a novel cigarette essence; and the application of the essence does not change the original performance and processing technique of the cigarettes, improves the aroma quality of the cigarettes, enhances the comfort of people smoking the cigarettes, and does not have any side effect. The hollyhock has the advantages of wide distribution range and abundant resources in China; and the production technique is simple and easy to operate and lower in production cost, and thus, has meanings and values for practical production.

Description

technical field [0001] The invention relates to the field of flavors and fragrances for tobacco, in particular to a method for preparing a water extract of marshmallow rhizome and its application in cigarettes as a fragrance for tobacco. Background technique [0002] At present, domestic cigarette products still have certain deficiencies in terms of physical moisture retention and sensory comfort. In order to improve the overall quality of cigarette products, research and exploration in the fields of tobacco leaf raw materials, processing technology and flavors and fragrances have been carried out one after another. One of the main solutions is to develop distinctive new tobacco flavors. Natural flavors have become the focus of research and development in recent years because of their rich fragrance, vivid fragrance, safety and environmental protection. [0003] my country has a vast land and abundant resources, a wide variety of plants, and the composition of active ingre...
