Example Embodiment

[0024] Example 1

[0025] 1) Raw material fruits: 400.5kg of nine-ripe blackberry fruits and 44.5kg of seven-ripe blackberry fruits are required to be fresh, disease-free, and undamaged, cleaned by a fruit washer, and drained for use.

[0026] 2) Ultra-fine grinding: Use a high-shear ultra-fine grinding machine to beat and crush the drained blackberry fruits at a speed of 2900-5000r / min. Filter with a 300 mesh filter to obtain 400 kg of black berry pulp and 45 kg of pomace.

[0027] 3) Preparation of auxiliary materials: purified water: food grade, in line with my country's "Sanitary Standards for Domestic Water"; 120kg of white sugar, 10kg of honey: food grade, in line with national health standards. The white granulated sugar is prepared into a 55.2% white granulated sugar solution by a hot melt method, filtered with a 200-mesh filter membrane, and then cooled and filled in a cold tank for later use. Stir honey and warm water to make 50% honey water, cool, filter and fill in a c...

[0031] Example 2

[0032] 1) Raw material fruits: 378.2 kg of fresh, pest-free, and undamaged fully ripe blackberry fruits and 66.8 kg of eight-ripe blackberry fruits are required to be cleaned by a fruit washer, removed from impurities, and drained for use.

[0033] 2) Ultra-fine grinding: Use a high-shear ultra-fine grinding machine to beat and crush the drained blackberry fruits at a speed of 2900-5000r / min. Filter with a 300 mesh filter to obtain 400 kg of black berry pulp and 45 kg of pomace.

[0034]3) Preparation of auxiliary materials: purified water: food grade, in line with my country's "Sanitary Standards for Domestic Water"; white sugar 110kg, honey 10kg: food grade, in line with national health standards. The white granulated sugar is prepared into a 55.2% white granulated sugar solution by a hot melt method, filtered with a 200-mesh filter membrane, and then cooled and filled in a cold tank for later use. Stir honey and warm water to make 50% honey water, cool, filte...

Abstract

The invention relates to a processing method of fresh blackberry juice. The produced juice has fresh color and good taste and is free of pigment. The fresh blackberry juice is made by pulping 85 to 90 weight percent of 90 percent or above ripe blackberry fruit and 10 to 18 weight percent of 70 to 80 percent ripe blackberry fruit. As an improvement of the invention, the raw fruit is comminuted into superfine particles and pulped and then filtered through screens of 300 meshes. As another improvement of the invention, ultra-high temperature instantaneous sterilization and cold-aseptic filling are applied to the juice. The ultra-high temperature instantaneous sterilization is performed at the temperature of 128 to132 DEG C for 3-5s; and then, the juice is cooled instantaneously with ice water to about 18 to 23 DEG C and then filled under aseptic conditions. The invention eliminates the need of pigment addition and combines fully-natural juice with improved technologies, improving the blackberry taste defect, maintaining natural and fresh nutrients and cool and ruddy rosy luster of the blackberry fruit and lengthening the shelf life of the fresh juice.

Description

technical field [0001] The invention relates to a processing method of freshly squeezed blackberry juice, which belongs to the technical field of fruit juice processing. Background technique [0002] Blackberry (Blackberry) is a berry plant belonging to the genus Rubus in the family Rosaceae. Blackberry fruit is rich in nutrients such as sugar, acid, various amino acids, and vitamins. Blackberry berries also contain biologically active substances such as isocitric acid, vitamin E, SOD, γ-aminobutyric acid, and flavonoids. The mysterious fruit of life with health care function. Lishui County introduced blackberries from the United States for the first time in 1987 through the Institute of Botany, Chinese Academy of Sciences, Jiangsu Province. After more than 20 years of experimentation, demonstration and promotion, it has now built a blackberry production base of 50,000 mu, the largest in the country. Blackberry has a unique flavor, but its taste is poor when eaten fresh, a...
