Concentrated orange juice and manufacturing method thereof

Abstract

The invention belongs to the technical field of fruit juice beverages, and specially, relates to concentrated orange juice and a manufacturing method thereof. The concentrated orange juice is prepared from 35 to 45 parts by weight of orange paste, 15 to 25 parts by weight of sugar, 1 to 3 parts by weight of citric acid, 0.1 to 0.5 parts by weight of malic acid, 3 to 5 parts by weight of modified starch, 0.1 to 0.3 parts by weight of xanthan gum, 0.1 to 0.3 parts by weight of pectin, 0.0001 to 0.00025 parts by weight of sodium hydrosulphite, and 35 to 45 parts by weight of water. The manufacturing method comprises the following steps of 1, raw material preparation, 2, uniform mixing, 3, boiling in water, 4, gelatinization, and 5, blending. The concentrated orange juice has good stability. An orange juice beverage prepared from the concentrated orange juice through dilution has a fresh and sweet taste and a difficultly changed color. The manufacturing method is easy for operation and reduces a production cost.

Description

technical field [0001] The invention belongs to the technical field of fruit juice beverages, in particular to a concentrated orange juice and a preparation method thereof. Background technique [0002] Juice drinks are juice products obtained from fruits through physical methods such as pressing, centrifugation, extraction, etc. Juice drinks are rich in nutrients and contain a variety of vitamins, especially vitamin C, and contain calcium, phosphorus and other minerals (inorganic salts) . And the vitamin C in the orange reaches 30mg / 100ml, and vitamin C content is high, so orange juice drink is very popular. [0003] Existing orange juice beverage is to use fresh oranges, through selection, cleaning, degreasing, squeezing the juice, filtration, centrifugation, deployment, degassing, sterilization, filling, cooling, to obtain the finished orange juice beverage, but the obtained orange juice beverage The pulp of the finished product is prone to sinking (storage at -18°C for...

Problems solved by technology

[0003] Existing orange juice beverage is to use fresh oranges, through selection, cleaning, degreasing, squeezing the juice, filtration, centrifugation, deployment, degassing, sterilization, filling, cooling, to obtain the finished orange juice beverage, but the obtained orange juice beverage The finished pulp is prone to sinking (storage at -18°C for 1 day, the pulp begins to sink), the color is also prone to change, and the stability is poor, which is not conducive to normal consumption

And the preparation method of existing orange juice beverage is complicated, and manufacturing step is many, and production cost is high
