Embodiment 1

[0024] A preparation method of lychee essence, specifically comprising the steps of:

[0025] (1) Pretreatment: Select fresh lychees with natural color, ripe fruit, and no pests and diseases, dry them in an oven at 60°C, remove the peel and core, and take out the pulp;

[0026] (2) Crushing and beating: According to the water: litchi pulp (m / m) = 1:1, use a high-speed tissue masher (speed 12000rpm / min) to beat for 5 minutes to obtain litchi pulp;

[0027] (3) Filtration under reduced pressure: Pour the obtained lychee pulp on the filter paper of the Buchner funnel, and filter under reduced pressure to obtain the filtrate;

[0028] (4) Yeast fermentation: add active dry yeast to the filtrate (the amount of active dry yeast added is 0.2% of the mass of the filtrate), and incubate at a constant temperature of 35°C for 2 hours to obtain a culture medium;

[0029] (5) Baking at high temperature: put the culture medium in an oven, evaporate the water at 70°C, and bake at 130°C for ...

[0036] A preparation method of lychee essence, specifically comprising the steps of:

[0037] (1) Pretreatment: Select fresh lychees with natural color, ripe fruit, and no pests and diseases, dry them in an oven at 50°C, remove the peel and core, and take out the pulp;

[0038] (2) Crushing and beating: According to the water: litchi pulp (m / m) = 1.5:1, use a high-speed tissue masher (rotating speed 10000rpm / min) to beat for 10 minutes to obtain litchi pulp;

[0039] (3) Filtration under reduced pressure: Pour the obtained lychee pulp on the filter paper of the Buchner funnel, and filter under reduced pressure to obtain the filtrate;

[0040] (4) Yeast fermentation: add active dry yeast to the filtrate (the amount of active dry yeast added is 0.4% of the filtrate mass), and incubate at a constant temperature of 45°C for 1 hour to obtain a culture solution;

[0041] (5) Baking at high temperature: put the culture medium in an oven, evaporate the water at 80°C, and bake at 150°...

Embodiment 3

[0048] A preparation method of lychee essence, specifically comprising the steps of:

[0049] (1) Pretreatment: Select fresh lychees with natural color, ripe fruit, and no pests and diseases, dry them in an oven at 55°C, remove the peel and core, and take out the pulp;

[0050] (2) Crushing and beating: according to water: lychee pulp (m / m) = 2:1, use a high-speed tissue masher (speed 11000rpm / min) to beat for 15 minutes to obtain lychee pulp;

[0051] (3) Filtration under reduced pressure: Pour the obtained lychee pulp on the filter paper of the Buchner funnel, and filter under reduced pressure to obtain the filtrate;

[0052] (4) Yeast fermentation: add active dry yeast to the filtrate (the amount of active dry yeast added is 0.1% of the filtrate mass), and incubate at 40°C for 3 hours to obtain a culture solution;

[0053] (5) Baking at high temperature: put the culture medium in an oven, evaporate the water at 60°C, and bake at 110°C for 4 hours to obtain the aroma substa...

Abstract

The invention discloses a preparation method of litchi essence. The preparation method of the litchi essence comprises the following steps: 1) mixing litchi pulp and water to prepare litchi thick liquid, and filtering the litchi thick liquid under reduced pressure to obtain filtrate; 2) adding active dry yeast in an amount which is 0.05 to 0.5 percent of the mass of the filtrate into the filtrate, and cultivating at 30 to 45 DEG C for 1 to 5 hours to obtain culture liquid; 3) evaporating the culture liquid to dryness at 60 to 80 DEG C, and baking at high temperature of 100 to 160 DEG C for 2 to 4 hours to obtain a baked litchi flavor substance; 4) adding 80 to 90 percent by volume of ethanol solution into the baked litchi flavor substance, and refluxing at 70 to 90 DEG C for 2 to 4 hours to obtain extracting liquid; and 5) concentrating the extracting liquid under reduced pressure to obtain the litchi essence, wherein the dry substance content of the litchi substance is 10 to 20 percent by weight. The cost of the litchi essence is low, the process is simple, and the litchi essence is sprayed on cut tobaccos uniformly by a cigarette perfuming procedure, so the baking sweetness of the cigarette can be highlighted, and the smoking quality and the sensory comfort level are improved.

Description

technical field [0001] The invention belongs to the technical field of preparation and application of natural spices, and in particular relates to a lychee essence, its preparation method and its application in cigarettes. Background technique [0002] With the rapid development of my country's economy, consumers have higher and higher requirements for the inherent quality of cigarettes. Moreover, compared with well-known foreign brands, domestic cigarette products have a certain gap in smoking quality and sensory comfort, such as weak aroma, strong dryness, insufficient sweetness, and poor comfort. Therefore, it is an inevitable trend in the development of domestic cigarettes to increase the aroma of cigarettes, reduce dryness, and improve comfort. [0003] Litchi juice is sweet and nutritious. It is not only rich in sucrose, glucose and fructose, but also contains a lot of amino acids, which provide raw materials for the Maillard reaction. However, up to now, there has b...
