Problems solved by technology

The fruit juice produced by this method generally has the following disadvantages: more nutrients, especially vitamins, are lost, the flavor of the fruit is changed to a large extent, and the fresh taste of the fruit is lost.
These fruits are not easy to preserve after ripening, mainly because the above-mentioned enzymes will quickly soften the fruits within a few hours after ripening and are prone to spoilage. These phenomena are difficult problems in the processing of tropical fruits
