Description

A kind of method of producing jujube essence concentrated nutrient solution

Technical field

The present invention relates to a kind of method of from wooden jujube, extracting juice, refer to a kind of method of producing jujube essence concentrated nutrient solution especially.

Background technology

At present, scum juice after the broken jujube of the many employings of the method for extraction nutrient solution from jujube, sugaring, Jia Shui, perfuming and anticorrisive agent, or adopt boiling, filtration, concentrated.The natural nutrition that these processing methods have all been destroyed jujube very much; The product unclarity; Even deposition or the visible suspension of naked eyes are arranged, and jujube nuclear, fructus corni, jujube meat are separated separately, the storage life is generally less than 1 year; Therefore all there are very big drawback and limitation from quality and on the shelf life, await improving.

Summary of the invention

The purpose of this invention is to provide a kind of method of producing jujube essence concentrated nutrient solution, it is used for addressing the above problem.

To achieve these goals, the technical solution of the utility model is: a kind of method of producing jujube essence concentrated nutrient solution may further comprise the steps:

(1) the wooden jujube that examination is obtained cleans, pick;

(2) product that step (1) is obtained lixiviate 120 minutes in the lixiviate jar;

(3) product that step (2) the is obtained stoning of pulling an oar, and remove fructus corni through refiner, make the turbid juice that contains jujube meat get into surge tank;

(4) the turbid juice that step (3) is obtained carries out pasteurize, enzymolysis;

(5) the turbid juice that step (4) is obtained is transferred to extraction equipment through pump and extracts, and extract gets into surge tank;

(6) extract that step (5) is obtained is transferred to ultrafiltration system and filters;

(7) the clear juice that step (6) is obtained is sent in the evaporimeter and is concentrated, and sends into the finished product jar when extract is concentrated into pol greater than 65 ° of BX;

(8) juice that step (7) is obtained carries out can after the pasteurize.

Described a kind of method of producing jujube essence concentrated nutrient solution, wherein the wooden jujube in the lixiviate jar in the step (2) and the weight ratio of water are 1:3.

Described a kind of method of producing jujube essence concentrated nutrient solution, wherein lixiviate jar temperature remains on 70 ℃ in the step (2).

Described a kind of method of producing jujube essence concentrated nutrient solution, wherein turbid juice gets into enzymatic vessel for 50 ℃-55 ℃ in temperature in the step (4).

Described a kind of method of producing jujube essence concentrated nutrient solution wherein adds the pectase of 50-100ppm in the step (4) in the enzymatic vessel, the enzyme time is 45 minutes.

Described a kind of method of producing jujube essence concentrated nutrient solution, wherein the ultrafiltration aperture is 0.1um in the step (6).

Described a kind of method of producing jujube essence concentrated nutrient solution, wherein evaporating temperature is smaller or equal to 70 ℃ in the step (7).

Described a kind of method of producing jujube essence concentrated nutrient solution, wherein the sterilization temperature to pasteurization conduit and fill head is 110 degree in the step (8), the time is 40 minutes.

Described a kind of method of producing jujube essence concentrated nutrient solution, wherein the sterilization temperature in the step (4) is 90 ℃-95 ℃, the time was greater than 30 seconds.

After adopting such scheme, the present invention does not add any anticorrisive agent and other raw material because wooden jujube and pure water that employing is dried are raw material, has fully kept the natural nutrient component in the wooden jujube; Adopt in the processing to be lower than 70 ℃ of temperature extraction nutrient solutions, can make wooden jujube in extraction, avoid the infringement of high temperature, avoided conventional high-temperature to extract the burnt burning that is produced jujube nutrition; Adopt advanced enzymeization, separation, filtering technique can make product limpid bright, taste is purer, does not have deposition, does not have macroscopic suspension and impurity; Adopt the vacuum concentration technique that product moisture is reduced, the product pol more is prone to store more than or equal to 65 ° of BX, and the storage life can reach 3 years; The independent separation of jujube nuclear, fructus corni, jujube meat helps the further development and use of jujube nuclear, fructus corni, jujube meat.

The specific embodiment

Embodiment 1

The wooden jujube that the present invention adopts maturation to dry, wooden jujube quality, weight, impurity, the source of factory entered in inspection, the wooden jujube planting base pollution-free, that use country to forbid agricultural chemicals of confirming whether hang oneself raw material company's investigation confirming.

The wood jujube cleans through water in tank, by elevator the wooden jujube in the tank is risen to and carries out the flushing of secondary water in second section Rinsing Area, and water for cleaning meets the GB5749 standard-required.

Wooden jujube transport tape after the cleaning is delivered to chooses the fruit platform, removes by choosing will go rotten rotten fruit and foreign material of fruit worker, and the wooden jujube after the selection gets into rotary drum with conveyer belt and cleans.Clear water sprays the silt dirt in the further flush away wood jujube.

Wooden jujube lixiviate in the lixiviate jar of cleaning is sent 70 ℃ of hot water into the lixiviate jar earlier during lixiviate, and the wooden jujube of cleaning is then sent into the lixiviate jar by elevator; The weight ratio of wood jujube and water is 1:3; Heat to material by steam during lixiviate, make extraction temperature remain on 70 ℃, 120 minutes time; Diffusion water is to use the pure water of producing through the water-making machine group; This extracting technology adopts the continuous lixiviate mode of automation fully, and extraction temperature, time, water and raw material weight all can be set in computer, and system accomplishes batching, insulation, lixiviate automatically according to setting.

The wood jujube is transferred to beater by centrifugal pump after lixiviate, remove jujube nuclear; Can separate fructus corni separately through the fructus corni separation equipment again; Separate jujube meat through jujube meat separation equipment again, the turbid juice that will contain jujube meat at last gets into surge tank; Turbid juice is through preceding pasteurize, and sterilization temperature is 90 ℃, and the time was greater than 30 seconds; Get into enzymatic vessel after being cooled to 50 ℃, add pectase in the enzymatic vessel, carry out the enzyme processing; The pectase consumption is 60ppm, and the enzyme time is 45 minutes, and the turbid juice behind the enzymolysis is transferred to extraction equipment by pump and extracts; Extraction equipment is to utilize action of centrifugal force, and jujube meat is separated with extract, and isolated extract gets into surge tank.

Extract is transferred to ultrafiltration system by pump in surge tank, the aperture of ultrafiltration is Φ 0.1um, makes like this greater than the solid content more than the Φ 0.1um, bacterium, virus etc. all to be eliminated, and it is as clear as crystal that extract becomes, and the clear juice after ultrafiltration gets into clear juice jar.

By being pumped into evaporimeter, evaporimeter adopts the vacuum drop kestner long-tube evaporator to clear juice in clear juice jar, 70 ℃ of evaporating temperatures, and extract evaporates redundant moisture in evaporimeter, when extract is concentrated into pol greater than 65 ° of BX, delivers to the finished product jar by screw pump.

Before the can, the pipeline and the fill head of pasteurize are carried out high temperature sterilization, sterilization temperature is 110 ℃, 40 minutes time; The jujube essence extract is through pasteurize during can; Sterilization temperature is 92 ℃, and the time was cooled to below 30 ℃ greater than 30 seconds; Prepare can; Extract can be killed the microorganism in the extract after pasteurize, make product be easy to preserve, and extract can carry out can 100,000 grades of cleaning shops after pasteurize.

Embodiment recited above describes preferred implementation of the present invention, is not that design of the present invention and scope are limited, and the content that the present invention asks for protection all is documented in claims.
