Embodiment 1

[0026] A preparation method of snowflake pear extract for tobacco, comprising the following steps:

[0027] A. Washing the snow pear, peeling and removing the core, cutting into pieces, adding a pretreatment agent, dehydrating after beating to a moisture content of ≤ 2%, and obtaining a snow pear pretreatment;

[0028] The pretreatment agent is formed by mixing ascorbyl palmitate and sorbitol with a mass ratio of 1:7; the amount of the pretreatment agent is 2% of the mass of pear;

[0029] B, take half of the snowflake pear pretreatment, use the volume fraction of 60% ethanol to leach at 45°C for 1.5 hours, filter after cooling, and concentrate to a relative density of 1.2800 to obtain the first extract; the amount of ethanol is 4 times of the amount of pear pretreatment substance;

[0030] C. Take the snowflake pear pretreatment of the other half quality, extract with ethyl propionate at 45°C for 1.5 hours, filter after cooling, and concentrate to a relative density of 1.280...

Embodiment 2

[0033] A preparation method of snowflake pear extract for tobacco, comprising the following steps:

[0034] A. Washing the snow pear, peeling and removing the core, cutting into pieces, adding a pretreatment agent, dehydrating after beating to a moisture content of ≤ 2%, and obtaining a snow pear pretreatment;

[0035] The pretreatment agent is formed by mixing ascorbyl palmitate and sorbitol with a mass ratio of 2:7; the amount of the pretreatment agent is 5% of the mass of snow pear;

[0036] B, take half of the quality snowflake pear pretreatment, use the volume fraction of 60% ethanol to extract at 60 ℃ for 1 hour, filter after cooling, concentrate to a relative density of 1.2880, and obtain the first extract; the consumption of ethanol is snow pear 4 times of the amount of pear pretreatment substance;

[0037] C. Get the other half of the quality snowflake pear pretreatment, leaching with ethyl propionate for 1 hour at 60°C, filter after cooling, and concentrate to a rel...

Embodiment 3

[0040] A preparation method of snowflake pear extract for tobacco, comprising the following steps:

[0041] A. Washing the snow pear, peeling and removing the core, cutting into pieces, adding a pretreatment agent, dehydrating after beating to a moisture content of ≤ 2%, and obtaining a snow pear pretreatment;

[0042] The pretreatment agent is formed by mixing ascorbyl palmitate and sorbitol with a mass ratio of 1:7; the amount of the pretreatment agent is 3% of the mass of pear;

[0043] B, take half of the snowflake pear pretreatment, use the volume fraction of 60% ethanol to extract at 50 ℃ for 1.2 hours, filter after cooling, and concentrate to a relative density of 1.2720 to obtain the first extract; the consumption of ethanol is snow pear 3.5 times of the pear pretreatment substance quality;

[0044] C. Take the snowflake pear pretreatment of the other half of the quality, extract it with ethyl propionate at 50°C for 1.3 hours, filter after cooling, and concentrate to ...

Abstract

The invention belongs to the technical field of flavors and fragrances, and proposes a preparation method of snowflake pear extract for tobacco, comprising the following steps: A, washing the snowflake pear, peeling and removing the core, cutting into pieces, adding a pretreatment agent, and dehydrating after beating , to obtain snowflake pear pretreatment; said pretreatment agent is formed by mixing ascorbyl palmitate and sorbitol with a mass ratio of 1 to 2:7; B, getting half of the quality snowflake pear pretreatment, The fraction is 60% ethanol leaching, filtering, and concentrating to obtain the first extract; C, taking the other half of the quality of snowflake pear pretreatment, leaching with ethyl propionate, filtering, and concentrating to obtain the second extract; D. Mixing the first extract and the second extract to obtain the snow pear extract for tobacco use. Through the above technical scheme, the problems of low content of flavonoids and low extraction rate in the snowflake pear extract obtained by the extraction method in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of flavors and fragrances, and relates to a preparation method of snowflake pear extract for tobacco. Background technique [0002] Snow pear belongs to the white pear system, and its main production areas are Hebei, Shandong, Liaoning, Hubei, Jiangsu, Anhui, Sichuan, Gansu and other provinces, among which Zhao County snow pear is an excellent variety. Snow pear cultivation in Zhao County has a long history, which can be traced back to more than two thousand years ago. Snowflake pear is named for its white flesh like jade, like frost and snow. It is said in history that it is "big like a fist, sweet like honey, and crisp like a water chestnut". Its fruit is big, round, thin-skinned and thick-fleshed Good color, juicy and sweet taste, it is as famous as Zhaozhou Bridge. Snowflake pears are often used as raw materials for food or health products, such as processing canned food, pear juice, pear paste, preser...
