DETERMINATION OF THE NUTRITIONAL QUALITIES AND MINERALS CONTAINED IN DRIED PRODUCTS FROM DIFFERENT VARIETIES OF TRADITIONAL ROMANIAN APPLES

Abstract

The aim of this work was to quantify the content of nutritional elements and minerals in dried products from traditional Romanian old apple varieties from Salaj county, with potential for production and introduction into population consumption, as well as establishing shelf life for dried apples without the addition of preservatives, on the technological flow. The apple varieties evaluated were "Jonathan", "Poinic", "Mustos - sample 2", "Summer- not nominally identified", "Winter- not nominally identified", "Mustos - sample 1", "Dulce", as well as 2 mixes with apples "Mix of dried apples (from the Poinic, Mustos, Dulce, Summer, Winter, Ionathan varieties)" and "Summer variety dried apple mixed with dried chokeberry and dried blackcurrant"(contains apples from the "Summer- not nominally identified"). The samples taken in the study continued the skin and pulp of the fruits. The minerals iron, manganese, magnesium, potassium, calcium and sodium were evaluated. The evaluated nutritional indicators were the content of available carbohydrates, energy (Kj/100g, kcal/100g), energy from fats, ash content, fat content, dietary fiber, protein, dry matter, moisture. The evaluated minerals showed significant differences depending on the variety. The variety 'Jonathan' was noted for its high content of iron 8.1 mg/kg. High manganese content was detected in "Jonathan" variety - 2.11 mg/kg and in "Dulce" variety - 3.11 mg/kg. The "Summer- not nominally identified" variety was noted for its high content of sodium 14.4 mg/kg and calcium 276 mg/kg. The "Poinic" variety stood out for its high potassium content 6380 mg/kg. The "Winter- not nominally identified"variety stood out for its high magnesium content of 377 mg/kg. The results indicated the high nutritional potential of apples from old traditional Romanian varieties.
