Concentrated apple juice

How to make juices

Concentrated juice from apples is produced bydirect extraction of raw materials. The resulting juice is sent to centrifuges, where it is cleaned of suspensions, and then heated and sent to a special installation. Here, aromatic substances are trapped, which are then packaged in a concentrated form into containers. At the same stage, water evaporates to 15% of the total volume. The remaining liquid raw materials without aromatic constituents are sent to the clarification stage by pectolytic enzymes with gelatin for 4 hours, and then passed through the lamellar and kieselguhr filters located one after the other. As a result, a clear, clarified juice is obtained, which is then "evaporated" in thin-film "steam rooms" to a solids content of 70%.

Quite often before the capture procedurearomatics freshly squeezed juice is heated to 92-96 ° C and immediately cooled to 40 ° C. Thus there is a coagulation of colloidal particles and purification of juice from various microorganisms.

Chemical composition of juices

Apple juice in concentrated form hasa very interesting chemical composition. It contains from 60 to 80% of amine nitrogen from the total content of total nitrogen. In addition, the concentrate contains amino acids such as valine, leucine, threonine, aminobutyric acid, lysine, arginine, aspartic acid, serine, asnaragin, glutamic acid, phenylalanine, alanine, tyrosine. It also contains a large amount of monosaccharides, which under the action of high temperature and low pH decompose into components with the formation of 5-hydroxymethylfurfural.

Classification of juice

Any concentrates, including concentrated apple, have their own classification, which depends on the drinks that will subsequently be made from them:

  1. Semi-finished products. They are used to make 100% of apple juices by adding water.
  2. Fundamentals. This type of concentrate is used for making beverages and various nectars.
  3. Concentrates that have undergone intermediate processingat the factory. It is believed that such concentrates contain 100% of apples. But in fact it is not so. It is in such concentrated apple raw materials that sugar, other fruit concentrates or flavors identical to natural ones are most often added. Such a category of concentrates is not frosted, but packed into aseptic packaging.
  4. Pure apple concentrates with 100% contentmain component. They are produced only from high-quality apples in the places of their cultivation. In this case, such concentrates are most often subjected to freezing.

Usage and appearance

Apple concentrate is similar in appearance to a syrup veryDense consistency in color corresponding to the color of apples. If the juice contains flesh or it was frozen, it looks like soft ice cream. It should be noted that in the frozen concentrate, in no case there should be ice crystals.

Concentrated juice from apples has a widescope of use. Nectars, reconstituted juices and juice-containing drinks are made from it. In addition, the concentrate is used to prepare various jellies, all kinds of fillings. But nevertheless, it is worth remembering that in pure form apple concentrate can not be used for food.
