Vegetable juice extraction technology
1. Press juice is suitable for vegetables rich in juice, pigment stability, easy to squeeze, such as celery, radish, cabbage and so on. Raw vegetables can be mechanically pressed after washing, slicing or blanching.
2. Solvent extraction Juice extraction After the vegetables are divided, they are soaked and extracted with organic solvents such as alcohol or high-permeability substances such as salt and sugar. The organic solvent extraction rate is generally 2% to 20%, but this method has the problem of solvent residue. The heating method can be used to extract a vegetable juice with a lower boiling point, such as mint juice; the juice extracted with a solution such as salt or sugar can be used to directly prepare other vegetable juices.
3. Heating the juice For some vegetables with high gel content and oxidase content, use heating method to make the colloidal material lose its gelling property, and then cool the juice to extract juice; or directly collect the hot blanching liquid, and then obtain it after treatment. Juices, such as carrots, ginger, etc.
4. Steam retention Fragrant extraction of vegetables containing aromatic substances, so that the products do not lose the above substances due to heat treatment, often using high-pressure and high-temperature steam into the raw materials, to force the volatile substances volatile, and then use the cooling condensation Collect it. After the juice is taken out, the condensate dissolved in the aromatic substance is added to it. The sap obtained by this method has a rich flavor and the typical aroma of raw materials is prominent, such as the processing of concentrated vegetable juice.
