AB  - In this study, the possible use of seeds after fruit processing to obtain unconventional cold-pressed edible oil was investigated. For this purpose, seeds of quince, sour cherries and plum were used. Fatty acid composition, antioxidant activity, peroxide and acid value, oxidative stability, and tocopherols and phytosterols content were determined in the studied oils. Plum seed oil was dominated by oleic acid, while quince and sour cherry seed oils contained abundant linoleic acid. The total polyphenol content in the studied oils ranged from 2.28 to 9.03 mg GAE 100 mL-1. Antioxidant properties (ABTS, DPPH, FRP) were associated with tocopherol content. All three studied oils were rich in β-sitosterol. The oxidative stability of the studied oil samples varied and ranged from 1.92 h-31.17 h. Quince seed oil had the highest content of α-tocopherol (44.30 mg 100 g-1) and plum seed oil had the lowest (3 mg 100 g-1), while sour cherry seed oil had the highest content of β+γ-tocopherol (17.19 mg 100 g-1). The results show that oil from quince, sour cherry, and plum seeds is suitable for the production of a high quality cold-pressed oil. The use of this type of waste from fruit processing contributes to waste reduction and promotes the circular economy.

AB  - Potato chips and French fries are products which are often used in the human diet. The aim of this study was to investigate the influence of cutting thickness, shape and moisture content on palm olein uptake, as well as the quality of the palm olein during the production of fried potatoes. Blanching operation was conducted in water for 3 minutes at a temperature of 85oC, while the frying process was conducted in palm olein for 3 minutes at a temperature of 165oC. The peroxide value and free fatty acid content (% oleic acid) were determined by standard analytical methods. The oil content in samples was determined by the standard Soxhlet extraction (the reference method). The results showed that the potato chips had approximately four times more oil uptake compared to potato sticks. The oil content was significantly lower in blanched potato slices (by 43.3%) but significantly higher in blanched potato sticks (by 53.5%) compared to unblanched samples. The analyzed quality parameters of palm olein were within the allowable value range. Based on the results obtained in this study, it can be concluded that the thickness, surface area and moisture content of the potato had a significant effect on oil uptake.
