The concentration of a fruit juice is a widely used practice in the fruit juice manufacturing industry, and it has two main purposes: (1) to reduce the volume and weight of the product, with the subsequent lowering of storage, packaging and distribution costs, and (2) to increase the stability of the juice by reducing its water activity, which is a predominant factor in the majority of the mechanisms of deterioration. Although other methods of concentration such as
freezing concentration and reverse osmosis are used nowadays, evaporation is still the most popular due to operational and economic reasons.
