Problems solved by technology

In addition, the form of fruit juice is not limited by seasons, and many other nutrients can be added. The color is bright, and it is a good processing form in terms of sensory, flavor and nutrition. However, the prepared pomegranate juice often has the problem of fading after a period of time. Some have even lost their original luster and color after being prepared, which affects sales.

Effect test

Embodiment 1

[0017] Wash the pomegranates with water, perform three-level sorting, and use the Italian Berducci peeling machine to peel the pomegranate seeds, then heat the pomegranate seeds to 78°C for 2 minutes, then cool to 50°C for 1 minute, and squeeze the seeds; the obtained pomegranates Coarsely filter the turbid juice, add pectinase to decompose, add gelatin for flocculation and sedimentation, after partial filtration and ultrafiltration, use vacuum low-temperature evaporation equipment to conduct one-effect concentration at 76Kpa, 56-58°C, and conduct at 88Kpa, 48-50°C Two-effect concentration, three-effect concentration at 96Kpa, 40-42°C; the sugar content automatic controller is used to control the concentration, when the sugar content reaches 65°BX, the juice pump is started, and the product is input into the aseptic filling machine for filling to obtain the color. Vibrant concentrated pomegranate juice.

Embodiment 2

[0019] Wash the pomegranates with water, perform three-level sorting, and use the Italian Berducci peeling machine to peel the pomegranate seeds, then heat the pomegranate seeds to 80°C for 1 minute, then cool to 48°C for 2 minutes, and squeeze the seeds; the obtained pomegranates The turbid juice was coarsely filtered, and amylase was added to decompose it, and bentonite was added for flocculation and sedimentation. After partial filtration and ultrafiltration, vacuum low-temperature evaporation equipment was used for three-effect concentration. Others were as in Example 1 to obtain brightly colored concentrated pomegranate juice.

Abstract

The invention belongs to the field of the deep processing of a fruit, and in particular to a method for color protection of pomegranate juice. Before the juice extraction of the pomegranate, pomegranate seeds are heated up to the temperature of between 75 and 80 DEG C, kept warm for 1 to 3 minutes, cooled down to the temperature of between 48 and 50 DEG C and kept warm for 1 to 2 minutes; and after the juice extraction of the pomegranate, the juice is subjected to enzymolysis, clarification and filtration, and vacuum-condensed at a temperature of between 40 and 70 DEG C to obtain the pomegranate juice with bright color. The method has the advantages of simple method, easy operation, unnecessary addition of other additives, the suitability for all processes for preparing the pomegranate juice and good color protecting effect, and the pomegranate juice obtained by the method does not fade when stored at a temperature of between 4 and 8 DEG C or in a refrigerated warehouse at a temperature of 15 DEG C below zero for half a year.

Description

(1) Technical field [0001] The invention belongs to the field of deep processing of fruits, in particular to a method for protecting the color of pomegranate juice. (2) Background technology [0002] Pomegranates are native to Russia, Iran, Afghanistan, and Turkey, and later spread westward to countries along the Mediterranean Sea, and eastward to India and China. Pomegranates are distributed in subtropical and temperate regions. The fruit is bright red. Inside the hard outer skin, there are many crystal clear ruby-like seeds. Although there are seeds in the grain, it is sweet and delicious, juicy and refreshing, and it is very delicious. [0003] Except for the skin, film and seeds, the edible part of pomegranate is about 10%. After testing, every 100 grams of pomegranate edible part contains about 67 calories, 81.1 grams of water, 0.6 grams of protein, 0.2 grams of fat, and 16.8 grams of sugar. grams, 0.8 grams of fiber, 0.5 grams of minerals, 8 mg of calcium, 15 mg of p...
