Canned fruits are a resource at the preservation and use level of fruit farms that have accompanied man for centuries. In this way, large batches of fruit that are due to seasonality, become food for the rest of the year. On the other hand, it is a solution for the difficulties that the transport of certain fruits can present and the deterioration that can generate long journeys such as boat trips in the seventeenth century.
Throughout human history, sugar, for example that found in honey, has been used as a preservative . In this way, it is difficult to determine the exact point in which canned fruits were conceived, and these can be presented in different ways, perhaps more primitive than those we know today. Thus, the elaboration of the different preserves has not undergone major changes, being sugar, water and fruit its only ingredients. To obtain some of the products that we know, heat would be added to the equation, to make possible the process in which the meat of the fruit is cooked with sugar until a mixture with gel texture is achieved. . The key in this recipe is the hygroscopic character of sugar, that is, its ability to absorb moisture. In this way the fruit dries and microorganisms cannot proliferate , added to the pressure generated in the membranes of their cells, the risk of their reproduction is eliminated. Finally, the delicious inert pasta is obtained that resists the passage of years. Done correctly, and hermetically packaged it remains intact until the moment it is exposed to the air again.
