SummaryWaxes play an important role in maintaining fruit quality and shelf‐life extension because they are naturally effective in blocking the migration of moisture. In this work, cuticular waxes from Physalis peruviana calyx (PPC) were extracted and characterised as potentially hydrophobic materials. Extraction was carried out using the Soxhlet technique with two non‐polar solvents, hexane and petroleum ether, and one polar solvent, ethanol. The extraction yield, lipid characterisation, and hydrophobic potential of cuticular waxes from PPC were analysed and compared using thin‐layer chromatography (TLC), attenuated total reflectance‐infrared spectroscopy (ATR‐IR), GC–MS chromatogram (FAMES), and wetting contact angle. Extraction using hexane was the most efficient method (yield of 9.61 ± 0.37%) for obtaining cuticular waxes with better hydrophobic properties, characterised by a contact angle of = 107.37 ± 1.0° and a hysteresis contact angle of 11° due mainly to the presence of functional groups desirable and characteristic of vegetable waxes. Greater texture homogeneity visualised using optical microscopy and the presence of capric acid (70.97%) as a major component of low‐molecular‐weight fatty acids were observed in this extract. Due to their biodegradable, potentially antifungal, and hydrophobic properties, cuticular waxes from PPC have the potential to replace synthetic waxes in industrial applications.

“…UV absorption changes at 232 and 268 nm, measured as K232 and K268, provide insights on the degree of oxidative damage of lipids [ 60 ]. It was found that K232 is strongly correlated with the level of conjugated dienes (CDs) produced as a consequence of the primary oxidation process of polyunsaturated fatty acids, while K268 is more closely linked to the presence of conjugated trienes (CTs) and carbonyl compounds formed in response to secondary lipid oxidation processes [ 26 ].…”

Exploring new sources of natural antioxidants is of great interest to edible oil producers, in line with the toxicological problems generated by the use of synthetic antioxidants. This study assesses the potential of lyophilized Pinot Noir grape pomace extract (GPE) to enhance the sunflower oil stability against thermo-oxidative damage compared to BHT during a prolonged exposure to convective heat at 185 °C. Oil thermo-oxidation was monitored based on specific indices such as peroxide value (PV), para-anisidine value (p-AV), inhibition of oil oxidation (IO), total oxidation (TOTOX) value, conjugated dienes and trienes (CDs, CTs), but also by attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), where absorbance ratios A 3009 cm−1/A 2922 cm−1 (RI), A 3009 cm−1/A 2853 cm−1 (RII), A 3009 cm−1/A 1744 cm−1 (RIII) and RIV = A 1744 cm−1/A 2922 cm−1 (RIV) were investigated. GPE showed a significant inhibitory effect on oil thermo-oxidation and this response was concentration-dependent. Substantial decreases in the investigated indices, compared to the control without added antioxidants, were obtained after 4 h and 8 h of heat exposure of the 800 ppm GPE sample: PV (47%; 42%), p-AV (38%; 33%), IO (54%; 46%), TOTOX (41%; 37%), CDs (46%; 39%), CTs (44%; 29%). Oil exposure to heat resulted in changes in RI–RIV attributed to the reduction in the degree of unsaturation, in response to primary and secondary lipid oxidation. FTIR spectroscopy can be used to differentiate untreated and heat-treated oils based on the absorbance ratios. An inhibitory effect close to that of BHT was achieved by 500 ppm GPE, while a dose of 800 ppm provided greater protection against thermo-oxidation. Our results promote GPE as a natural additive to limit the thermo-oxidative damage of plant oils.

“…The friction of the pressed material arises on the surface of the turns, the walls of the perforated cylinder and the friction of the particles among themselves [37]. Also, it is important to take into account the resistance of the mechanism that regulates the size of the outlet opening for the cake (cone, diaphragm, ring) [38]. The friction of the pressed material arises on the surface of the turns, the walls of the perforated cylinder and the friction of the particles among themselves [39].…”

The article presents the investigation of constructive and technological parameters of an energy-efficient screw oil press. It is outlined the principle of operation of an energy-efficient screw oil press. The construction of the oil press is improved by the steam atomizer that is installed in the receiving hopper under the rifled rollers for moisture-thermal treatment with steam, which is completed with the heat exchanger, heating element, expansion tank and hydro group. Also, a steam generator connected to a steam atomizer which is embodied into the receiving hopper. It was analyzed the influence of the optimization criteria (oil yield, energy consumption and press productivity) on the efficiency of the technological process. These optimization criteria depend on the main independent factors: the length of the reception and preparation chamber, the material (sunflower pulp) moisture; the heating temperature, the screw rotation speed, the linear speed of movement of screw shaft turns. The optimal constructive and technological parameters of energy-efficient screw oil press are considered. The energy-efficient screw oil press refers to the equipment of the oil enterprises of small productivity and due to its design, it allows to use a simple technological scheme of oil pressing and to reduce the amount of energy and resources spent on the technological process in the context of use in sustainable food systems.
