[0028] The invention also relates to konjac hookah paste prepared by the preparation method.

[0029] The present invention will be described in more detail below.

[0030] The present invention relates to a method for preparing konjac hookah paste. The specific process of the preparation method of the present invention is shown in Schematic Diagram 1.

[0031] Konjac is the underground tuber of a perennial herbaceous plant of the genus Amorphophallus Bl.ex Decne. of the family Araceae, and its main component is glucomannan. The present invention uses a manufacturing process of alkalization molding and freezing pores in the process of preparing the konjac hookah paste matrix, so that the prepared hookah paste matrix has high specific surface area and elastic properties. After adsorbing spices and functional materials, the entire hookah paste is isolated from external adverse environmental factors, while maintaining the original color, fragrance and taste of the hookah paste, it also reduces deterioration losses and extends the shelf life. The present invention uses konjac flour to prepare the hookah paste, which can accurately control the amount of each component added, which not only enriches the demand of hookah smokers for traditional hookah paste, but also reduces the harm of traditional hookah to the body.

[0032] The preparation steps of this preparation method are as follows:

[0033] A. Preparation of edible alkali aqueous solution

[0034] Dissolve 2.5 to 22.5 parts by weight of edible alkali in 94 to 141 parts by weight of purified water, stir evenly, and heat to a temperature of 40 to 80° C., thereby obtaining the edible alkali aqueous solution;

[0035] According to the present invention, the main function of edible alkali in preparing the konjac hookah paste matrix is ​​to inactivate the glutenase in the konjac and cross-link with the konjac polysaccharide to solidify it into a shape and make it elastic.

[0036] The edible alkali used in the present invention is sodium carbonate, sodium bicarbonate or a mixture thereof, which are all products currently sold on the market.

[0037] In the present invention, when the amount of pure water and the heating temperature are within the range, if the amount of edible alkali is less than 2.5 parts by weight, the konjac hookah paste matrix is ​​loose and broken and difficult to form; if the amount of edible alkali is higher than 22.5 parts by weight, the konjac hookah paste matrix will have a pungent smell; therefore, it is reasonable to use edible alkali in an amount of 2.5 to 22.5 parts by weight, preferably 3.5 to 19.7 parts by weight, and more preferably 7.5 to 15.7 parts by weight;

[0038] When the edible alkali consumption and the heating temperature are within the described scope, if the consumption of pure water is lower than 94 weight portions, then the edible alkali concentration is higher, and during the alkalization of the konjac gel, can't be evenly alkalized; If the consumption of pure water is higher than 141 weight portions, then the edible alkali concentration is lower, can't reach the molding effect, and the konjac hookah paste matrix can't be molded; Therefore, the consumption of pure water is suitable for 94~141 weight portions, preferably 101~135 weight portions, more preferably 110~125 weight portions;

[0039] When the amount of edible alkali and the amount of pure water are within the described range, if the heating temperature is lower than 40°C, the edible alkali is incompletely dissolved and the alkalization effect cannot be achieved; if the heating temperature is higher than 80°C, the edible alkali will undergo a decomposition reaction, the alkalinity will weaken, and the konjac gel cannot be alkalized, resulting in the inability to form the konjac hookah paste; therefore, a heating temperature of 40 to 80°C is appropriate, preferably 48 to 72°C, and more preferably 52 to 68°C.

[0040] B. Preparation of Konjac Gel

[0041] 25-90 parts by weight of konjac flour, 9-59 parts by weight of modified starch and 1-10 parts by weight of edible plant gum are uniformly stirred and mixed, then added to 318-819 parts by weight of pure water, and heated to a temperature of 80-120° C. under stirring, until the solution viscosity reaches 2000-6000 mPa at this temperature, to obtain the described konjac gel;

[0042] In the present invention, the main function of the konjac flour in preparing the konjac hookah paste matrix is ​​to prepare the main material of the konjac hookah paste.

[0043] Described konjac flour is one or more konjac flours that are selected from common konjac flour, common konjac powder, common konjac micropowder, purification konjac flour, purification konjac powder or purification konjac micropowder, and its granularity is 40~200 orders.The konjac flour that the present invention uses all is the product sold in the market, for example the common konjac flour that is sold with trade name the common konjac flour of Johnson konjac by Hubei Johnson Konjac Technology Co., Ltd., the common konjac powder that is sold with trade name the common konjac powder of Johnson konjac by Hubei Johnson Konjac Technology Co., Ltd., the common konjac powder that is sold with trade name the common konjac powder of Johnson konjac by Hubei Johnson Konjac Technology Co., Ltd., the purification konjac powder that is sold with trade name the purification konjac powder of Johnson konjac by Hubei Johnson Konjac Technology Co., Ltd.

[0044] In the present invention, the main function of the modified starch in preparing the konjac hookah paste matrix is ​​to adjust the density of the konjac hookah paste matrix.

[0045] The modified starch is one or more modified starches selected from oxidized starch, sodium carboxymethyl starch, hydroxypropyl acetate starch or acetylated starch pregelatinized starch. The modified starches used in the present invention are all products currently sold on the market, such as oxidized starch sold under the trade name oxidized starch by Zhucheng Xingmao Corn Development Co., Ltd., sodium carboxymethyl starch sold under the trade name sodium carboxymethyl starch by Renqiu Shuangcheng Chemical Products Factory, hydroxypropyl acetate starch sold under the trade name hydroxypropyl acetate starch by Zhucheng Xingmao Corn Development Co., Ltd., acetylated starch sold under the trade name acetylated starch modified by Henan Fengwei Biotechnology Co., Ltd., and pregelatinized starch sold under the trade name pregelatinized starch by Shaanxi Xifu Biotechnology Co., Ltd.

[0046] In the present invention, the edible plant gum plays a major role in the preparation of the konjac hookah paste matrix, which is to increase the toughness and aroma release performance of the konjac hookah paste.

[0047] Described edible plant glue is one or more edible plant glues selected from xanthan gum, carrageenan, pectin or konjac gum.The edible plant glue that the present invention uses is all the product sold in the market, for example the xanthan gum sold with the trade name reduced gum by Henan Guangheng Food Ingredients Co., Ltd., the carrageenan sold with the trade name carrageenan by Qingdao Dehui Marine Biotechnology Co., Ltd., the pectin sold with the trade name pectin by Qingdao Dehui Marine Biotechnology Co., Ltd., the konjac gum sold with the trade name Johnson Konjac Konjac Gum by Hubei Johnson Konjac Technology Co., Ltd.

[0048] In this step, 25 to 90 parts by weight of konjac flour, 9 to 59 parts by weight of modified starch and 1 to 10 parts by weight of edible plant gum are mixed and then added to 318 to 819 parts by weight of pure water. When the amounts of modified starch, edible plant gum and pure water are within the described range, if the amount of konjac flour is less than 25 parts by weight, the target adsorption amount of smoke-generating agent, tobacco flavor and functional raw material cannot be reached; if the amount of konjac flour is higher than 90 parts by weight, the viscosity of konjac gel is too large, and the konjac hookah paste matrix cannot be formed; therefore, the amount of konjac flour is appropriately 25 to 90 parts by weight, preferably 32 to 82 parts by weight, and more preferably 40 to 72 parts by weight; konjac flour, When the amount of edible vegetable gum and pure water is within the range, if the amount of modified starch is less than 9 parts by weight, the density of the konjac hookah paste matrix is ​​small and the smoke-generating agent cannot be stably adsorbed; if the amount of modified starch is higher than 59 parts by weight, the density of the konjac hookah paste matrix is ​​large and the target adsorption amount of the smoke-generating agent, tobacco flavor and functional raw materials cannot be achieved; therefore, it is desirable that the amount of modified starch is 9 to 59 parts by weight, preferably 16 to 52 parts by weight, and more preferably 22 to 46 parts by weight. When the amount of konjac flour, modified starch and pure water is within the described range, if the amount of edible plant glue is less than 1 weight part, the konjac hookah paste has poor adhesion and low toughness; if the amount of edible plant glue is higher than 10 weight parts, the konjac hookah paste has close adhesion and poor aroma release performance; therefore, the amount of edible plant glue is appropriate in the range of 1 to 10 weight parts, preferably 2 to 8 weight parts, and more preferably 3 to 6 weight parts; the amount of konjac flour, modified starch and edible plant glue is between When within the described range, if the consumption of pure water is lower than 318 weight parts, konjac flour, modified starch and edible plant gum cannot be completely wetted and fused; If the consumption of pure water is higher than 819 weight parts, the concentrations of konjac flour, modified starch and edible plant gum are not enough, and the molding effect cannot be achieved, and the konjac hookah paste matrix cannot be molded; Therefore, the consumption of pure water is suitable for 318~819 weight parts, preferably 367~800 weight parts, and more preferably 412~790 weight parts;

[0049] In the present invention, described konjac flour, modified starch and edible plant gum are uniformly mixed, then added in pure water, under agitation are heated to 80~120 ℃ of temperature, until solution viscosity reaches 2000~6000mPa.Here, it is undesirable that this Heating temperature exceeds described scope, because konjac flour, modified starch and edible plant gum could be dissolved in pure water completely at described temperature, prepare konjac gel, if Heating temperature is higher than 120 ℃, konjac flour, modified starch and edible plant gum mixed solution easily gelatinize rapidly, alkalization can't molding; If temperature is lower than 80 ℃, konjac flour, modified starch and edible plant gum mixed solution viscosity are too high, can't evenly alkalize.Therefore, Heating temperature is that 80~120 ℃ is appropriate, preferably 85~110 ​​℃, more preferably 90~100 ℃.

[0050] In the present invention, the main purpose of controlling the solution viscosity within the range of 2000 to 6000 mPa is to control the viscosity of the konjac gel and ensure that the alkalization process can completely alkalize the konjac gel. The solution viscosity is tested according to the GB / T 22235 standard method.

[0051] C. Preparation of matrix raw material mixture

[0052] The edible alkali aqueous solution obtained in step A is slowly added to the konjac gel obtained in step B, and the mixture is rapidly stirred for 20 to 70 seconds at a temperature of 80 to 120° C. until the solution viscosity reaches 4000 to 10000 mPa. After cooling and forming, the solution is dehydrated using a centrifugal solid-liquid separator, and the obtained solid is dried and crushed to 2 to 10 mm under low-temperature vacuum conditions to obtain a konjac hookah paste matrix raw material mixture;

[0053] The edible alkaline water is slowly added to the konjac gel, stirred continuously, and heated to 80-120°C. At this temperature, the solution is rapidly stirred for 20-70 seconds until the solution viscosity reaches 4,000-10,000 mPa. This is primarily to control the density of the konjac shisha paste matrix and ensure its molding and adsorption properties. The solution viscosity is tested according to the GB / T 22235 standard method. Then, a low-temperature cooling method is adopted to perform cooling and molding at a temperature of 0 to 20° C., the main purpose of which is to enable the alkalized konjac gel to be porous-molded; the cooled molded product is centrifuged and dehydrated for 20 to 80 minutes at a rotating speed of 500 to 4000 rpm using a centrifugal solid-liquid separator to remove free water contained in the cooled molded product; then, the product is dried and crushed to 2 to 10 mm in a vacuum drying oven at a temperature of 0 to 40° C. and a vacuum degree of 0.1 to 0.001 MPa to remove bound water contained in the cooled molded product, thereby obtaining a konjac hookah paste base raw material mixture having a water content of less than 12% by weight; and the water content of the konjac hookah paste base raw material mixture is detected according to the GB 5009 standard analysis method.

[0054] The konjac hookah paste base material mixture can be added with beneficial components commonly contained in cigarette products, such as nicotine salts, nicotine, and liquid tobacco oil, and their usage should also be within the reasonable content range of these cigarette products. Of course, these beneficial components should also be within the scope of protection of the present invention.

[0055] The centrifugal solid-liquid separator and low-temperature vacuum drying oven used in the present invention are products currently sold on the market, such as the solid-liquid centrifugal separator sold by Taizhou Lijing Washing Equipment Co., Ltd. under the trade name three-legged stainless steel industrial dehydrator, and the low-temperature vacuum drying oven sold by Nanjing Huozao Machinery Technology Co., Ltd. under the trade name low-temperature vacuum oven.

[0056] D. Add smoke agent and flavor

[0057] The konjac hookah paste matrix raw material mixture obtained in step C is added to a reactor, followed by adding 210 to 954 parts by weight of hookah smoke agent and 80 to 150 parts by weight of tobacco flavoring, stirring for 0.5 to 6.0 hours at a stirring speed of 10 to 40 rpm, and filtering to remove excess solution to obtain the konjac hookah paste.

[0058] According to the present invention, the main function of the hookah smoking agent in the konjac hookah paste is to atomize the tobacco flavoring or other ingredients adsorbed by the konjac hookah paste into steam for inhalation.

[0059] The water pipe smoke generating agent used in the present invention is propylene glycol, glycerol or a mixture thereof, which are all products widely sold in the market.

[0060] In the konjac hookah paste matrix raw material mixture obtained in step C, if the amount of the hookah smoke agent is less than 210 parts by weight, the smoke generation amount is too small, the atomization is weak, and the components in the konjac hookah paste cannot be effectively atomized; if the amount of the hookah smoke agent is higher than 954 parts by weight, the konjac matrix cannot be completely absorbed, and liquid is brought out into the oral cavity during the atomization process; therefore, the amount of the hookah smoke agent is appropriately 210 to 954 parts by weight, preferably 275 to 917 parts by weight, and more preferably 325 to 839 parts by weight;

[0061] According to the present invention, the main function of the tobacco flavoring in the konjac hookah paste is to highlight the flavor characteristics of the hookah paste and adjust the flavor of the hookah paste.

[0062] The tobacco flavoring used in the present invention is one or more tobacco flavorings selected from fruit flavors, flower flavors, herbal flavors, tobacco flavors, coffee flavors, or tea flavors. Specifically, the tobacco flavoring used in the present invention is strawberry flavor, blueberry flavor, apple flavor, mango flavor, peach oolong flavor, rose flavor, tobacco flavor, Paan, coffee flavor, or black tea flavor, all of which are currently available on the market, such as strawberry flavor sold under the trade name Tobacco Strawberry by Yunnan Nanzhong Technology Co., Ltd. and tobacco flavor sold under the trade name Tobacco Flavor by Yunnan Chunxu Biotechnology Co., Ltd.

[0063] In the konjac hookah paste matrix raw material mixture obtained in step D, if the amount of tobacco flavoring is less than 80 parts by weight, the original flavor characteristics of the flavoring cannot be highlighted; if the amount of tobacco flavoring is more than 150 parts by weight, the flavoring taste is too strong, and there is retention in the mouth after inhaling the atomized smoke; therefore, the amount of tobacco flavoring is appropriately 80 to 150 parts by weight, preferably 90 to 140 parts by weight, and more preferably 95 to 130 parts by weight.

[0064] The mixture of konjac hookah paste base raw materials with added smoke generating agent and flavor is stirred at a stirring speed of 10 to 40 rpm for 0.5 to 6.0 hours. When the stirring time is within the range, if the stirring speed is less than 10 rpm, the konjac hookah paste base is not completely absorbed; if the stirring speed is greater than 40 rpm, the hookah paste base is easily broken, affecting the adsorption effect; therefore, a stirring speed of 10 to 40 rpm is appropriate; when the stirring speed is within the range, if the stirring time is less than 0.5 hour, the konjac hookah paste base is not absorbed enough and cannot be completely absorbed; if the stirring time is longer than 6.0 hours, the konjac hookah paste base is broken, affecting the absorption and smoking effect; therefore, a stirring time of 0.5 to 6.0 hours is appropriate, and preferably 1.5 to 5.0 hours.

[0065] In this step, the filtration is performed using a filtration device with a 10-40 mesh filter medium and a temperature of 20-40° C. until no liquid is discharged, thereby obtaining the konjac hookah paste matrix.

[0066] The filtering equipment used in the present invention may be, for example, a filter separator, a solid-liquid filter, or a basket filter, all of which are currently commercially available products, such as the inclined screen filter sold by Zhengzhou Tianqi Machinery Equipment Co., Ltd. under the trade name "Inclined Screen Solid-Liquid Separator." The filtering media used in the present invention may be, for example, a stainless steel filter screen, a quartz filter screen, a ceramic filter screen, or an activated carbon filter bag, all of which are currently commercially available products, such as the stainless steel screen filter sold by Anping County Dingya Wire Mesh Products Co., Ltd. under the trade name "Plain Weave Filter Screen."

[0067] When the filtration temperature is in the described scope, if the filter medium mesh number is less than 10 meshes, the konjac matrix easily leaks down; if the filter medium mesh number is greater than 40 meshes, the smoke-generating agent solution can't be filtered dry; Therefore, it is desirable that the filter medium mesh number is 10~40 meshes, preferably 18~32 meshes; When the filter medium mesh number is in the described scope, if the filtration temperature is lower than 20 ℃, the filtration efficiency reduces; If the filtration temperature is higher than 40 ℃, the fragrance will be lost, which will cause the fragrance of the konjac hookah paste to be insufficient; Therefore, it is suitable that the filtration temperature is 20~40 ℃, preferably 26~34 ℃.

[0068] The present invention also relates to the konjac hookah paste prepared by the preparation method of the present invention.

[0069] With reference to GB 5606.4-2005 Cigarettes Part 4: Sensory Technical Requirements, three hookah smokers were invited to evaluate the konjac hookah paste of the present invention; at the same time, Samara hookah paste sold by Yiwu Haochi Daily Necessities Factory, VG hookah paste sold by Yiwu Luhe E-Commerce Firm, and Alfakher hookah paste sold by Yiwu Yixi Trading Co., Ltd. were also evaluated as control samples. The evaluation results can be found in the specific implementation method section.

[0070] In addition, the tobacco flavor retention rate of the konjac hookah paste of the present invention was detected using an Agilent 8860 universal GC chromatography system in the United States. The specific detection method is as follows:

[0071] A. Equipment

[0072] the RY200 hookah sold by Pujiang Rongyang Arts and Crafts Co., Ltd. under the trade name Arabic hookah;

[0080] The sampling times are 10th, 20th, 30th and 40th minutes;

[0081] D. The formula for calculating the retention rate of tobacco flavor is as follows: Tobacco flavor retention rate % = A 抽吸 / A 未抽吸

[0082] Where:

[0083] A 抽吸 represents the flavor content of konjac hookah paste after each puff, weight %;

[0084] A 未抽吸 Represents the flavor content of konjac hookah paste when not smoked, in weight %.

[0085] The results of the evaluation are shown in the detailed description. [Beneficial Effects]

[0086] The beneficial effects of the present invention are as follows: the konjac hookah paste of the present invention is a hookah paste with rich fragrance and controllable fragrance carrying amount. Compared with the existing hookah paste, the konjac hookah paste of the present invention has better adjustability, richer fragrance, saturated fragrance, obvious smoke production, long-lasting fragrance, and is safe to smoke, which better meets consumers' demand for hookah paste.
