The juice is generally divided into clear juice and turbid juice. Common clear juice includes pineapple juice, grape juice, watermelon juice, blueberry juice, blackberry juice, etc. Turbid juice has orange juice, tomato juice, carrot juice, etc. Fruit juice with flesh usually includes peach, apricot, plum, plum, etc. Process flow of fruit juice processing: pretreatment (selection, cleaning, crushing, heat treatment)- juicing- coarse filtration- ingredient adjustment- fine filtration- homogeneous degassing- concentration- sterilization- filling.
Pretreatment process of fruit juice
In the process of pretreatment, it is important to use dilute hydrochloric acid or fatty acid for washing the fruits and vegetables with more pesticide residues. After crushing and before squeezing, preheating treatment is mostly needed. The purpose is to soften the tissue of the flesh and improve the yield of the juice. In addition, different preheating temperatures can promote or inhibit enzyme activity. According to the properties of enzyme, proper pH value, temperature and action time will directly affect the color and flavor of the final product. Therefore, according to different market demands, we must grasp the different processing technologies.
