Problems solved by technology

But this disclosed technology needs to rely on nanofiltration and ultrafiltration and reverse osmosis equipment, and in the process of removing the deterioration source in the watermelon, will inevitably cause original soluble solids, organic acid, amino acid in the watermelon juice, to amino acid, aromatic substance A large number of losses such as small molecules, so due to the lack of ingredients, to be precise, the product prepared according to the application scheme can only be called a drink containing watermelon ingredients, rather than watermelon juice with full ingredients, it can only be in the absence of watermelon and watermelon Juice preservation means case of desperation

Embodiment 1

[0031] Watermelon cleaning and disinfection--beating--vacuum conditioning--aseptic filling--ultrahigh pressure treatment--low temperature storage

[0032] Watermelon cleaning and disinfection: In a clean workshop with an air cleanliness of 100,000, fresh, seedless watermelons without cracks (Heimi No. 5 variety, commercially available) are washed to remove sediment and sundries under flowing water. Immerse in sterilized water containing 200ppm chloride ions for 5 minutes, rinse with clean running water after taking it out, and place it in a cool and ventilated place to dry.

[0033] Beating: Peel the washed watermelon, take the pulp and cut it into pieces, put it into the beater immediately, fill the beater with nitrogen (nitrogen is food-grade nitrogen produced by a nitrogen generator, with a purity of 99.99%), until the beater is In a closed high-nitrogen environment (which can be regarded as anaerobic) with an oxygen content of less than 3% (volume content), start the beati...

[0039] Watermelon cleaning and disinfection--beating--aseptic filling--ultrahigh pressure treatment--low temperature storage

[0040] Watermelon cleaning and disinfection: In a clean workshop with an air cleanliness of 100,000, complete and fresh seedless watermelons (the new No. Chloride ion disinfection water for 5 minutes, rinse with clean running water after taking it out, and place it in a cool and ventilated place to dry.

[0041] Beating: Peel the washed watermelon, take the pulp and cut into pieces, put it into the beater immediately, fill the beater with nitrogen (nitrogen purity 99.99%, food grade), until the oxygen content in the beater is 1-3% Close the high-nitrogen environment, turn on the beating machine, control the speed of 3000rap / min, and take 5 minutes until the watermelon pulp is evenly broken, and the particle size is 0.15-0.18mm, which becomes the primary watermelon juice.

[0042] Aseptic filling: the above-mentioned primary watermelon juice is directl...

[0046] Watermelon cleaning and disinfection--peeling and pulp--aseptic packaging--beating and beating--ultra-high pressure treatment--low temperature storage

[0047] Watermelon cleaning and disinfection: In a clean workshop with an air cleanliness of 100,000, complete and fresh seedless watermelons (the new No. Chloride ion disinfection water for 5 minutes, rinse with clean running water after taking it out, and place it in a cool and ventilated place to dry.

[0048] Peel and pulp: Peel the washed watermelon, remove the pulp and cut into pieces.

[0049] Aseptic packaging: the obtained watermelon pulp (can be cut into pieces as the case may be) is aseptically packaged under the condition of filling nitrogen until the oxygen content is lower than 3%; the packaging form is bagged, and the material is EVOH (ethylene-vinyl alcohol copolymer). objects), the packaging bag should be cleaned and disinfected in advance and stored properly, and the aseptic packaging bag filled with w...

Abstract

The invention provides a method for preparing watermelon juice. The method comprises the following steps of: pulping watermelon flesh to prepare an initial product of the watermelon juice under an anaerobic environment, carrying out ultrahigh pressure processing on the initial product of the watermelon juice, and then arranging the processed product at 0-10 DEG C for storing, wherein the anaerobic environment means that the oxygen content of an environment is not higher than 3%. The invention further provides the watermelon juice. According to the method disclosed by the invention, elements in the watermelon juice, such as original small molecular flavor matters, soluble solid matters, organic acid, amino acid and the like, are greatly preserved, thus damages on main color rendering materials and thermo-sensitive flavor substances in the watermelon due to temperature and oxygen are avoided, and fresh taste watermelon juice with original cleaning flavor of a fresh watermelon is obtained.

Description

technical field [0001] The invention provides a processing technology of watermelon products, in particular to a watermelon juice capable of maintaining the unique fresh flavor of watermelon and a processing method thereof, belonging to the field of food processing. Background technique [0002] Watermelon belongs to Cucurbitaceae (Cucurbitaceae) botanically, watermelon (Citrullus), watermelon species, annual vine herb. [0003] Modern medical research shows that watermelon contains a variety of nutrients and beneficial substances needed by the human body, such as a large amount of sucrose, fructose, and glucose, rich in vitamin C, organic acids, amino acids, and minerals such as calcium, phosphorus, and iron. A certain amount of lycopene, but almost no fat. The urine produced by eating watermelon can dissolve excess salt in the body and prevent the formation of stones in the body. The rich folic acid contained in watermelon can be directly absorbed by the human body when ...
