Problems solved by technology

However, so far, there has been no report on the theoretical research and industrial practice of using longan as the raw material for the Maillard reaction to prepare tobacco flavors. Therefore, the development of a longan flavor has great theoretical and practical significance for cigarette flavoring.

Embodiment 1

[0026] A preparation method of longan essence, which comprises the following steps:

[0027] (1) Peeling and removing seeds: Select mature longan with high sugar content and high juice yield, remove the skin and longan seeds with a knife to obtain longan pulp;

[0028] (2) Crushing and beating: the longan pulp is beaten with a high-speed tissue masher for 2 minutes at a speed of 11,000 rpm to obtain longan pulp;

[0029] (3) Filtration under reduced pressure: filter the obtained longan pulp with a Buchner funnel under reduced pressure, and collect the filtrate;

[0030] (4) Concentration under reduced pressure: Concentrate the filtrate under reduced pressure at 45°C and 55KPa to obtain concentrated longan juice. The dry matter content in the concentrated longan juice is 30%;

[0031] (5) Maillard reaction: Add 30g of longan concentrated juice, 10g of maltose, 10g of proline and 400g of propylene glycol in a 1000ml three-neck flask equipped with a reflux tube and a stirrer, he...

Embodiment 2

[0043] A preparation method of longan essence, which comprises the following steps:

[0044] (1) Peeling and removing seeds: Select mature longan with high sugar content and high juice yield, remove the skin and longan seeds with a knife to obtain longan pulp;

[0045] (2) Crushing and beating: the longan pulp was beaten for 15 minutes with a high-speed tissue masher at a speed of 12000 rpm to obtain longan pulp;

[0046] (3) Filtration under reduced pressure: filter the obtained longan pulp with a Buchner funnel under reduced pressure, and collect the filtrate;

[0047] (4) Concentration under reduced pressure: Concentrate the filtrate under reduced pressure at 60°C and 65KPa to obtain concentrated longan juice. The dry matter content in the concentrated longan juice is 25%;

[0048] (5) Maillard reaction: add 40g of longan concentrated juice, 10g of honey, 10g of glycine and 400g of propylene glycol to a 1000ml three-necked bottle equipped with a reflux tube and a stirrer, ...

Embodiment 3

[0057] A preparation method of longan essence, which comprises the following steps:

[0058] (1) Peeling and removing seeds: Select mature longan with high sugar content and high juice yield, remove the skin and longan seeds with a knife to obtain longan pulp;

[0059] (2) Crushing and beating: the longan pulp was beaten with a high-speed tissue masher for 20 minutes at a speed of 10,000 rpm to obtain longan pulp;

[0060] (3) Filtration under reduced pressure: filter the obtained longan pulp with a Buchner funnel under reduced pressure, and collect the filtrate;

[0061] (4) Concentration under reduced pressure: Concentrate the filtrate under reduced pressure at 40°C and 70KPa to obtain concentrated longan juice. The dry matter content in the concentrated longan juice is 35%;

[0062] (5) Maillard reaction: Add 30g of longan juice concentrate, 10g of malt extract, 5g of alanine and 350g of propylene glycol in sequence in a 1000ml three-neck flask equipped with a reflux tube ...

Abstract

The invention discloses a preparation method of longan essence. The method comprises steps as follows: longan pulp is smashed and pulped, reduced pressure filtration and reduced pressure concentrationare performed, a sugar source and an ammonia source are added to concentrated juice, the mixture is subjected to a reaction at the temperature of 100-180 DEG C for 1-5 h, an organic solvent with thevolume being 3-10 times that of the mixture is added, the mixture is subjected to heating reflux for extraction at the temperature of 45-80 DEG C for 1-4 h; primary and secondary molecular distillation is performed on an extracting solution under certain conditions, and a light phase obtained through evaporation is the longan essence. The preparation process is simple, the cost is low, the obtained longan essence is uniformly sprayed to cut tobaccos through a cigarette flavoring procedure, the baked sweet or scorched sweet fragrance of cigarettes can be highlighted, the smoking quality and thesensory comfort of the cigarettes are improved, and the longan essence is worth popularization and application in the whole industry.

Description

technical field [0001] The invention belongs to the technical field of preparation and application of natural spices, and in particular relates to a longan 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. However, compared with well-known foreign brands, domestic cigarette products have certain gaps 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] Longan (scientific name: Dimocarpus longgana Lour.) is not only rich in nutrition and comprehensive, but also has certain health care functions. Longan has high sugar content, protein, fat, vitamin B, C, phosphorus, calc...
