AB  - This study aims to explore the influence of screw frequency, nozzle diameter, and press head temperature on critical crude fodder radish seed oil (FRSO) yield, throughput, and fatty acid composition. A quadratic equation, developed using response surface methodology, fitted the experimental data for oil yield. It was substantiated by a non-significant lack-of-fit, commendable coefficient-of-determination (R2 = 0.782), and a modest mean relative percentage deviation (±7.27%). The analysis of variance pinpointed the statistical significance of press head temperature, nozzle size, and the squared term of press head temperature. The highest FRSO yield (17.61%)—corresponding to an extraction efficiency of 51.3% was found with a screw frequency of 50 Hz, at 80°C, and an 8 mm nozzle. A linear model highlighted that all three pressing factors significantly influenced the FRSO throughput. FRSO consists of C18:1 (30.9%), C22:1 (20.8%), C18:2 (14.9%), and C18:3 (11.9%), aligning with the compositions reported in other studies on fodder radish oils.

AB  - Cold pressing is frequently used to produce high-quality vegetable oils, especially from seeds with high oil content, such as rapeseeds. But, it encounters a challenge from the industrial demand for high oil yield. Modeling the cold pressing process using experimental and statistical approaches would help to understand the effects of cold pressing conditions on oil yield and process efficacy. Therefore, this work aimed to investigate the effects of nozzle diameter (8–12 mm), screw frequency (40–60 Hz), and press head temperature (40–80 °C) on the oil recovery from rapeseeds by cold pressing using response surface methodology coupled with a 33 full factorial design. An extended quadratic equation fitted the experimental data accurately and reproducibly, as proved by the acceptable coefficient-of-determination (R2 = 0.873), a not significant lack-of-fit (p = 0.872), and a very low mean relative percentage deviation (± 6.7%, 35 data). The ANOVA revealed that nozzle diameter, press head temperature, their interaction, three-factor interaction, and squared nozzle diameter influenced pressed oil yield significantly. The optimal condition for obtaining the highest pressed oil yield (26.7%) within the experimental domain was a nozzle diameter of 10 mm, a screw frequency of 50 Hz, and a press head temperature of 80 °C. The crude oil extraction degree achieved by cold pressing was 60.8% compared to the Soxhlet method. The rapeseed oil contains predominantly oleic, linoleic, linolenic, and palmitic acids, agreeing with other reported rapeseed oils.

AB  - This study reports for the first time the total extractive matter yield, total phenolics and total flavonoids content (TPC and TFC, respectively), chemical composition, and ability to scavenging 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals of the black mustard seed (BMS) extracts obtained by deep eutectic solvents (DESs). The following DESs: triethanolamine:glycerol (TEOA:G), triethanolamine:propylene glycol (TEOA:PEG), and choline chloride:urea (ChCl:U), as well as their mixtures with water and ethanol at a ratio of 1:4 (v/v), were used. Their extraction efficiencies were compared with the efficiency of ethanol that is most frequently used to extract phenolic compounds from BMS. The TPC and TFC of the obtained extracts were in the ranges of 19.9 +/- 0.1 to 32.2 +/- 0.2 mg gallic acid equivalents/g and 3.9 +/- 0.1 to 7.4 +/- 0.3 mg quercetin equivalents/g, respectively. The BMS extracts obtained with the pure ChCl:U and the mixtures of ChCl:U or TEOA:G with ethanol showed the best antioxidant activity (IC50 = 100 mg/mL). The obtained extracts contained syringic acid, ellagic acid, gallic acid, caffeic acid, caftaric acid, rutin, kaempferol, apigenin, taxifolin, hyperoside, and vitexin.

AB  - This study reports the yields, physicochemical properties, fatty acid compositions, and antioxidant activities of black mustard (Brassica nigraL.) seed oils extracted by cold pressing and the solvent extraction using different solvents (n-hexane, trichloroethylene, and a mixture of trichloroethylene and the triethanolamine:glycerol deep eutectic solvent (TEOA:G DES) with no or after pretreatment with the TEOA:G DES. Density (0.9791 +/- 0.0003-0.9851 +/- 0.0003 g/cm(3)), viscosity (121.15 +/- 1.62-123.32 +/- 0.10 mPas), boiling point (179-185 +/- 1 degrees C), refractive index (1.4692 +/- 0.0006-1.4758 +/- 0.0011), acid (2.08 +/- 0.19-3.22 +/- 0.15 mg KOH/g), iodine (99.2 +/- 1.6-105.4 +/- 1.5 g I-2/100 g), peroxide (1.68 +/- 0.01-1.82 +/- 0.03 mmol O-2/kg), and saponification values (165.1 +/- 2.7-169.4 +/- 2.3 mg KOH/g), fatty acid composition and antioxidant activity of the extracted oil were determined in order to evaluate its potential use as a foodstuff, a pharmaceutical or a feedstock for biodiesel production. Although the maceration of black mustard seeds with sole trichloroethylene yielded the highest oil yield of 31.10 +/- 0.42 g/100 g, it required almost twice the volume of trichloroethylene compared to the volume applied in the macerations after the pre-treatment with the TEOA:G DES and with the mixture of trichloroethylene/TEOA:G DES. The oil extracted by the extraction in the presence of TEOA:G DES has similar physicochemical properties but better antioxidant activity than the oil extracted by cold pressing.
