Embodiment 1

[0022] A kind of processing technology of sugarcane concentrated juice, its operation steps are:

[0023] (1) tearing and juicing: select fresh and ripe sugarcane, remove the raw materials of rotten pests, and clean the sugarcane epidermis;

[0024] (2) Coarse filtration: the raw sugarcane juice is beaten and filtered by a beater with a sieve diameter of 0.5mm, and then further filtered by a horizontal centrifuge with a sieve of 200 mesh to remove large particles such as sugarcane bran and sugarcane debris in the sugarcane juice Impurities, to obtain coarsely filtered sugarcane juice;

[0025] (3) Pre-sterilization and enzyme deactivation: heat the coarsely filtered sugarcane juice to 100°C, keep it for 3 minutes, perform pre-sterilization and deenzyme deactivation, and obtain heated sugarcane juice;

[0026] (4) Ceramic membrane ultrafiltration: send the heated sugarcane juice to the ceramic membrane ultrafiltration working tank, and perform ultrafiltration clarification wit...

Embodiment 2

[0034] A kind of processing technology of sugarcane concentrated juice, its operation steps are:

[0035] (1) Tearing and juicing: Select fresh and mature sugarcane, remove the raw materials of rotten pests, clean the sugarcane skin, use a tearing machine to tear the sugarcane into filaments, sheets, strips and other finely divided materials and send them into the Press the juicer to extract the juice. In order to increase the juice yield, you can spray a small amount of water on the bagasse obtained after the first juice extraction, and then squeeze the juice again to obtain the raw sugarcane juice;

[0036] (2) Coarse filtration: the raw sugarcane juice is beaten and filtered by a beater with a sieve diameter of 1.0 mm, and then further filtered by a horizontal centrifuge with a sieve of 400 mesh to remove large particles such as sugarcane bran and sugarcane debris in the sugarcane juice Impurities, to obtain coarsely filtered sugarcane juice;

[0037] (3) Pre-sterilization...

Abstract

The invention relates to a processing technology of sugarcane concentrated juice. The sugarcane concentrated juice is processed by taking sugarcanes as raw materials and performing six steps, namely juicing, coarse filtration, pre-sterilization, enzyme inactivation, ultrafiltration by a ceramic membrane, vacuum concentration and high-temperature instant sterilization. The sugarcane concentrated juice prepared by the processing technology provided by the invention has clear and transparent color and luster, rich aroma, and sweet and delicious taste, and can keep the original flavor and nutritional components of the sugarcanes; and furthermore, the precipitation of a precipitate and the production of turbidity are avoided in the storage period. By adopting the processing technology provided by the invention, the technical problems of relatively high loss of flavor substances and the nutritional components in the production process of the sugarcane concentrated juice, browning in the processing and storage processes, deterioration of the sugarcane juice in the enzymolysis process, easiness in formation of membrane scales to cause blockage of membrane pores when the organic membrane is used for ultrafiltration and clarification and the like are solved.

Description

technical field [0001] The invention relates to the technical field of fruit and vegetable juice processing, in particular to a processing technology of concentrated sugarcane juice. technical background [0002] Sugarcane is a unique subtropical fruit. It is rich in juice, high in sugar, and sweet in taste, and is widely loved by people. In addition, sugarcane also has the functions of clearing away heat and detoxification, promoting body fluid and quenching thirst, harmonizing the stomach and relieving vomiting, nourishing yin and moistening dryness, etc. It is a high-quality raw material for the production of beverages. At present, the method of making beverage with sugarcane juice mainly contains two kinds: a kind of is directly squeezed sugarcane juice and is mixed with beverage; Limited by resources and raw materials, it is impossible for beverage processing enterprises to directly extract sugarcane juice to make beverages. At present, most enterprises use concentrate...
