Abstract
Improper storage conditions for oilseeds lead to significant quantitative and qualitative losses.
The study aims to assess the quality of sunflower oil from seeds with different physicochemical characteristics resulting from improper storage conditions (temperature and humidity) and to identify the most effective methods for obtaining it under these conditions.
The seeds were stored in rooms at different temperatures (20 and 40°C) and relative air humidity (20, 40, and 60%, respectively) for a storage period of 4 months, with samples taken and analysed every 2 months.
In this sense, the main physicochemical characteristics of the batch of sunflower seeds studied (moisture (% max.), seed germination grade, and oil content) were monitored.
From the oil obtained by pressing, it was determined: relative density (g cm‑3 at 20°C), moisture (% max.), and free acidity (% oleic acid). This study is valuable and could be applied to horticultural oilseeds such as pumpkin seeds, grape seeds, walnuts, hazelnuts, and almonds.
