Produits dérivés des fruits et légumes — Détermination du résidu sec soluble — Méthode réfractométrique

ISO 2173:2003 specifies a refractometric method for the determination of the soluble solids in fruit and vegetable products.

This method is particularly applicable to thick products, to products containing suspended matter, and to products rich in sugar. If the products contain other dissolved substances, the results will be only approximate; nevertheless, for convenience the result obtained by this method can be considered conventionally as the soluble solids content.
