Problems solved by technology

[0002] People are very familiar with the fruit fragrance and are very popular. Natural fruit flavors are accompanied by fruity-ester-green fragrance and typical floral-sweet characteristics. Because they come from nature, they contain hundreds of aroma components. The unique natural fruit fragrance cannot be replaced by any synthetic rubber, so it is a very rare additive in the food, beverage, and cosmetic industries. Traditionally, the essence collected from fruit juice processing has a trans-2-hexenal content in the range of 150-300ppm. Low, unstable indicators, high transportation costs, and limited use, the development of high-power concentrated flavors meets the needs of industrial production

Embodiment １

[0017] 1. Resin cleaning: Soak the resin with 2BV ethanol for 2 hours, then use pure water 3BV / h to clean until there is no ethanol smell, and consume 6BV of pure water.

[0018] 2. Resin adsorption:

[0019] 2-1. Add the essence to be treated, the content of trans-2-hexenal is 214ppm, and the flow rate is controlled at 2BV / h;

[0020] 2-2. Take the permeate at intervals of 1BV to measure the content of trans-2-hexenal, until the concentration of trans-2-hexenal in the permeate of 8BV is 0;

[0021] 2-3. When the permeate reaches 44BV, the concentration of trans-2-hexenal is 225ppm, that is, the resin is saturated, and the essence is stopped.

[0022] 3. Elution:

[0023] 3-1. Use 3BV of pure water to replace the essence in the resin column;

[0024] 3-2. Gradually add 45% ethanol to elute, and the flow rate is controlled at 2BV / h;

[0025] 3-3. Collect the permeate after 0.5BV. When the concentration of trans-2-hexenal in the permeate reaches 8BV, the elution is stopped. ...

Embodiment 2

[0039] 1. Resin cleaning: Soak the resin with 2BV ethanol for 2 hours, then use pure water 3BV / h to clean until there is no ethanol smell, and consume 6BV of pure water.

[0040] 2. Resin adsorption:

[0041] 2-1. Add the essence to be treated, the content of trans-2-hexenal is 214ppm, and the flow rate is controlled at 2BV / h;

[0042] 2-2. Take the permeate at intervals of 1BV to measure the content of trans-2-hexenal, until the concentration of trans-2-hexenal in the permeate of 8BV is 0;

[0043] 2-3. When the permeate reaches 40BV, the concentration of trans-2-hexenal is 230ppm, that is, the resin is saturated, and the essence is stopped.

[0044] 3. Elution:

[0045] 3-1. Use 3BV of pure water to replace the essence in the resin column;

[0046] 3-2. Gradually add 45% ethanol to elute, and the flow rate is controlled at 2BV / h;

[0047] 3-3. Collect the permeate after 0.5BV. When the concentration of trans-2-hexenal in the permeate reaches 10BV, stop elution. When the ...

Abstract

The invention provides highly-concentrated essence and a preparation method. The highly-concentrated essence is obtained with a process as follows: essence is adsorbed through resin, the adsorbed highly-concentrated essence is eluted with ethanol, and the highly-concentrated essence is obtained. The preparation method comprises steps as follows: A, resin cleaning: the resin is soaked with ethanol and washed with pure water until the resin doesn't have ethanol flavor; B, resin adsorption: a low-concentration essence product is subjected to resin adsorption, and resin adsorption is stopped after resin is saturated; C, elution: highly-treated essence in the resin is eluted with the ethanol, and a permeating fluid is collected; D, mixing: the eluted permeating fluid is collected and mixed with a stock solution according to the requirements, and highly-concentrated essence with different concentrations is obtained; E, filling for storage. The resin is used for adsorbing the essence and the essence is eluted with ethanol after resin saturation, and the highly-concentrated essence product is obtained. No additives are added to the highly-concentrated essence product, the pure natural property is kept, and the highly-concentrated essence meets the environment-friendly concept of modern consumption, can be directly used for development and utilization of natural essence food and provides required flavor and taste of a beverage.

Description

technical field [0001] The invention relates to a high-power concentrated flavor and a preparation method thereof, in particular to a process for obtaining the high-power concentrated flavor by eluting the absorbed high-power flavor with ethanol after the flavor is adsorbed by a resin, which belongs to the technical field of fruit deep processing. Background technique [0002] People are very familiar with the fruit fragrance and are very popular. Natural fruit flavors are accompanied by fruity-ester-green fragrance and typical floral-sweet characteristics. Because they come from nature, they contain hundreds of aroma components. The unique natural fruit fragrance cannot be replaced by any synthetic rubber, so it is a very rare additive in the food, beverage, and cosmetic industries. Traditionally, the essence collected from fruit juice processing has a trans-2-hexenal content in the range of 150-300ppm. Low, unstable indicators, high transportation costs, and limited use, t...
