Example Embodiment

[0018] Example 1

[0019] (1) Use a three-effect falling film evaporator to concentrate fresh lychee juice into 75Brix lychee concentrated fructose, the evaporation temperature is controlled at 50 ℃, and the lychee water with typical lychee aroma evaporated during the concentration process is collected, on the top of the evaporator With a layer of water film, it can prevent the vaporized aroma components from volatilizing and running away. As the vaporized gas is liquefied, the aroma components will also return to the water. Because it is cooled in a confined space, the amount of dissolved air is small, so it is called It is litchi active water.

[0020] (2) Mix lychee concentrated fructose and lychee active water in a ratio of 1:7, and then use a 20 kV / cm electric field to sterilize for 10 seconds.

[0021] (3) Treat the sterilized mixture in a closed vessel with a frequency of 25kHz and a voltage of 40V for 30min to mix the concentrated fructose and litchi active water thoroughly,...

[0023] Example 2

[0024] (1) Use a three-effect falling film evaporator to concentrate fresh lychee juice into 75Brix lychee concentrated fructose. The evaporation temperature is controlled at 70°C, and the lychee water with typical lychee aroma evaporated during the concentration process is collected, on the top of the evaporator With a layer of water film, it can prevent the vaporized aroma components from volatilizing and running away. As the vaporized gas is liquefied, the aroma components will also return to the water. Because it is cooled in a confined space, the amount of dissolved air is small, so it is called It is litchi active water.

[0025] (2) Mix litchi concentrated fructose and litchi active water in a ratio of 1:6, and then use a 10 kV / cm electric field to sterilize for 8 seconds.

[0026] (3) The sterilized mixed liquid is treated by ultrasonic treatment with a frequency of 30 kHz and a voltage of 40 V for 25 minutes in a closed vessel to fully mix the concentrate...

[0028] Example 3

[0029] (1) Use a three-effect falling film evaporator to concentrate fresh lychee juice into 80Brix lychee concentrated fructose, the evaporation temperature is controlled at 60 ℃, and the lychee water with typical lychee aroma evaporated during the concentration process is collected, on the top of the evaporator With a layer of water film, it can prevent the vaporized aroma components from volatilizing and running away. As the vaporized gas is liquefied, the aroma components will also return to the water. Because it is cooled in a confined space, the amount of dissolved air is small, so it is called It is litchi active water.

[0030] (2) Mix lychee concentrated fructose and lychee active water in a ratio of 1:5, and then use a 30 kV / cm electric field to sterilize for 10 seconds.

[0031] (3) The sterilized mixed liquid is treated with an ultrasonic wave with a frequency of 35 kHz and a voltage of 40 V for 30 minutes in a closed container to fully mix the concent...

Abstract

The invention relates to an active litchi beverage and a production method thereof, and belongs to the field of beverage production. The production method for the beverage comprises the following steps: concentrating fresh litchi juice into 75-85 Brix litchi concentrated fructose by utilizing a three-effect falling-film evaporator, wherein the evaporating temperature is controlled to be between 45 and 85 DEG C; collecting litchi water with typical litchi aroma evaporated in a concentration process; mixing the litchi concentrated fructose and the litchi active water in the ratio of 1:7 to 1:5; sterilizing for 5 to 15 seconds by adopting an electric field of 10 to 30 kV/cm; treating the sterilized liquid mixture for 20 to 40 minutes in an airtight vessel by adopting the ultrasonic waves with the frequency of 20 to 40 kHz and the voltage of 40V, so that the litchi concentrated fructose and litchi active water are mixed uniformly and most gas in the liquid is removed; performing filling operation on the mixed liquid from which the gas is removed through an airtight pipeline to obtain the active litchi beverage. The active litchi beverage has refreshing taste, strong litchi aroma and good flavor and typical aroma of the litchi is remained very well.

Description

technical field [0001] The invention relates to an active lychee juice drink and a production method thereof, in particular to an active lychee juice drink with a refreshing taste, rich fruity lychee aroma and good flavor, well retaining the typical aroma of lychee, and being a weakly alkaline drink, it conforms to the weak alkalinity of the human body. According to the requirements of internal environment, it can provide a good internal and external environment for the life movement of cells, make cells more energetic, and greatly improve the quality and value of the active lychee beverage, which belongs to the field of fruit juice processing. Background technique [0002] Together with bananas, pineapples and longan, lychees are known as the "four major fruits in the southern country". Litchi is native to southern China and is a subtropical fruit tree, an evergreen tree about 10 meters high. The peel has scale-like protrusions, bright red, purple. When the pulp is fresh,...
