Abstract

The present invention relates to a method for producing orange juice from orange peel. The present invention has the difference from the existing method for producing orange juice from orange peel that the method for debitterizing the orange peel by adding the orange peel to alcohol solution for immersion is added. The bitterness of the orange juice treated by the method is completely removed; in addition, the orange juice has the color, the flavor and the taste of the natural orange juice, and nutritive indexes are not lower than those of the original orange juice.

Description

Method for producing orange juice with orange and tangerine peels

The present invention relates to a kind of method of producing orange juice, particularly a kind of method of producing orange juice with orange peel.

Present domestic production orange juice is mostly taked to convert the method for joining with synthetic food color, essence, asccharin, tangerine magma, citric acid and water according to certain ratio and is processed, the orange juice that processes does not in this way possess the characteristics of the natural color, smell and taste of former orange, and human body is also had certain harm.Also useful orange peel is produced the method for orange juice, tangerine slurry, its main production method is: the tangerine peel water that will choose is in advance macerated, scrape off (purpose is to remove bitter taste) with the white underwear in the hilt orange peel, boil after 4-5 hour and to pulverize, orange juice is wherein separated and formed the orange juice finished product behind the raw material such as sugaring, acid by a certain percentage.Simultaneously slurry taking-up is wherein also formed tangerine sauce finished product behind the raw material such as sugaring, acid by a certain percentage.This method is owing to take to remove with cutter the method for the white underwear of orange peel, so white underwear can not be removed totally, and taste is not good.The task of therefore removing bitter taste is to be difficult to thoroughly realize.

In produce food such as orange juice, tangerine sauce with orange peel, people had done a lot of trials to reduce bitter taste wherein: U.S. Patent number is 1813,366 patents state a kind of technology of removing orange skin bitter taste with physical method, this method is tangerine peel to be soaked several days in water or soaked several hours in citrus juice, then water or citrus juice are removed, further be processed into food such as beverage with the tangerine peel that removes bitter taste.The bitter substance citrus glycosides that this method contains from the mechanism orange peel is insoluble to cold water, promptly uses citrus juice to soak and also can not remove bitter taste fully.U.S. Patent number is 4581,241 patents state a kind of technology of removing citrus tangerine peel bitter taste, this technology be the orange peel that will grind and carbohydrate aqueous solution together, these mixtures are digested a period of time under about 90-110 temperature, mixture with this digestion heats a period of time in about 212 to 270 temperature then, to reach the purpose of subduction bitter taste.Its major technique characteristics are to take the method for high-temperature process, and this technology can not be removed the bitter substance in the orange peel fully, and its result still has a certain proportion of bitter substance to remain in the orange peel.

The object of the present invention is to provide a kind of method of removing the orange juice bitter taste fully, have the characteristics of natural color, and nutritive index is not second to former orange juice with orange peel production orange juice.

Task of the present invention is to realize with following method:

The nothing that screening in advance is good is gone rotten, the water immersion extremely soft back taking-up in 4-6 hour that orange peel bright in colour is put into four times of amounts drains, it is 50 ℃ that orange peel after draining is immersed in temperature, pectase concentration is 0.4-1%, after soaking 10-50 minute in the solution of pH value between 3-4, taking-up drains water, the alcoholic solution of orange peel being put into 50-95% soaks then, and the constant temperature that its alcoholic solution is remained on more than 40 ℃ soaked 3-6 hour down, also soaked overnight at normal temperatures, take out, then orange peel is cut into wide for the long filament of 4-5mm and put it into to boil in the water of four times of amounts to take out after 10-20 minute and drain.To boil orange peel long filament after draining and add the water that 2-3 doubly measures and make its under the 0.5-1.5 vapour pressure high pressure 15-30 minute, take out the back with the hot water injection more than 90 ℃ 2-3 time.The water that the orange peel that washed is added 12 times of amounts is crushed to below the 20 μ m with colloid mill, pulverizing the back separates slag with separation equipment with juice, the juice of the separating peculiar smell of under 320mmHg80 ℃ condition, finding time continuously to remove, time is 30-60 minute, then the juice that takes out is added 45% sucrose, 0.6% citric acid, 0.05% different Vc sodium, 0.06% sodium chloride, 0.1% algin, make its dissolving, be finished product.Remove fully with its bitter taste of orange juice that this kind method processes, and have the color of natural orange juice, and nutritive index is not second to former orange juice.

The present invention is to have added with alcoholic solution immersion orange peel with existing method difference with orange peel production orange juice and removes the method for bitter taste, thereby reaches the purpose of removing the orange juice bitter taste.

The best is executed example:

The water that the orange peel that screening is good is in advance put into four times of amounts soaks to take out to soft back in 5 hours and drains, it is 50 ℃ that orange peel after draining is immersed in temperature, pectase concentration is 1%, the pH value is to soak to take out after 30 minutes in 3.5 the solution rapidly water to be drained, putting into 80% alcoholic solution then soaks, and make that constant temperature took out after 4 hours under its condition that keeps 45 ℃, then orange peel is cut into the wide length of 4-5mm that is

Silk also puts it into to boil to take out after 15 minutes in the water of four times of amounts and drains.To boil orange peel silk after draining adds the water of 3 times of amounts and makes its high pressure 20 minutes under 0.7 vapour pressure, take out the back with 100 ℃ hot water injection 3 times, the water that the flushing back adds 12 times of amounts is crushed to below the 20 μ m with colloid mill, pulverizing the back separates slag with separation equipment with juice, the juice of separating down to eliminate the unusual smell 320mmHg80 ℃ condition, and the time is 30-45 minute.The juice that takes out is added 45% sucrose, 0.6% citric acid, 0.05% different Vc sodium, 0.06% sodium chloride, 0.1% algin, is finished product.

Claims

A kind of method of producing orange juice with orange peel, it is characterized in that the water that orange peel is put into four times of amounts soaked and drain after 4～6 hours, it is 50 ℃ that orange peel after draining is immersed in temperature, pectase concentration is 0.4～1%, soak in the solution of pH value between 3-4 to take out after 10-15 minute and drain, then orange peel being put into the 50-95% alcoholic solution soaks, and its alcoholic solution is remained under the 40-45 ℃ of constant temperature soaked 3-6 hour, taking-up is cut into long filament and is put into the water of four times of amounts and boil after 10-20 minute and drain, add the water that 2-3 doubly measures and make its under the 0.5-1.5 vapour pressure 15-30 minute, water with 90 ℃ after taking out washes 2-3 time, add, the water of 12 times of amounts is pulverized with colloid mill, pulverizing the back separates slag with separation equipment with juice, the juice of separating is at 320mmHg, found time continuously under 80 ℃ the condition 30-60 minute, then the juice that takes out is added 45% sucrose, 0.6% citric acid, 0.05 different Vc sodium, 0.06% sodium chloride, 0.1% algin makes its dissolving.
