“…In addition, a greater concentration gradient can be obtained during the diffusion process (Kemerli‐Kalbaran & Ozdemir, 2019). Stamenković et al (2020) reported that increasing the solvent/kernel ratio from 3 to 10 ml g −1 decreased Gibbs free energy from extracting corn germ oil with n ‐hexane, favoring the spontaneity of the process. The high solubility of triacylglycerols in n ‐hexane may favor the factors mentioned since the oil diffusivity also depends on the affinity of the oil constituents with the extraction solvent (Perrier et al, 2017).…”

“…reported that between 30°C to 60°C, the UAE of oil from hemp seed was favored by increasing the extraction temperature up to 45°C.The solvent to kernel ratio had a positive effect on the extraction of babassu kernel oil since high ratios result in a greater surfacesolvent contact area, which accelerates the diffusivity rate of the solvent inside the plant matrix and increases the oil yield(Jisieike & Betiku, 2020). In addition, a greater concentration gradient can be obtained during the diffusion process (Kemerli-Kalbaran & Ozdemir, 2019) Stamenković et al (2020). reported that increasing the solvent/kernel ratio from 3 to 10 ml g −1 decreased Gibbs free energy from extracting corn germ oil with n-hexane, favoring the spontaneity of the process.…”

The ultrasound-assisted extraction (UAE) was applied to enhance the extraction efficiency of oil from babassu kernel (BKO) using n-hexane as solvent. For this purpose, the effects of temperature (30 to 60°C), solvent to kernel ratio (6 to 10 ml g −1 ), and time (10 to 30 min) on oil yield (Y o ) were determined, in addition to assessing the effect of these variables in the characteristics of the obtained oil. In the condition of maximum extraction, the chemical composition of the oil was determined and the results were compared with the Soxhlet extraction. In the evaluated experimental range, the amount of solvent used in the process influenced the Y o , while time and temperature had no effect on the response variable. With this, a high oil removal of kernels (89.5% obtained by Soxhlet) was obtained in low conditions of time (10 min) and temperature (30°C), in addition to using a smaller amount of solvent (10 ml g −1 ) in relation to conventional technique (30 ml g −1 ). The lowest evaluated temperature (30°C) was also indicated to obtain an oil with higher content of phenolic compounds and antioxidant activity. BKO showed a predominance of lauric (~49.9%) and myristic acids (~15.6%), and high oxidative stability. The quality of the oil extracted by the UAE

“…Most of the crops and grains in the world are subjected to harvesting, sorting, storing, and processing into various grain and oil products for human consumption. Vegetable oil, particularly germ oil, is an important grain product which provides rich nutrition to human health because it contains a high content of unsaturated fatty acid [ 1 , 2 , 3 ]. Germ oil can also dissolve cholesterol that is accumulated in the blood.…”

Deoxynivalenol (DON) contamination in germs and germ oil is posing a serious threat to food and feed security. However, the transformation pathway, the distribution of DON, and its degradation products in edible oil refining have not yet been reported in detail. In this work, we systematically explored the variation of DON in maize germ oil during refining and demonstrated that the DON in germ oil can be effectively removed by refining, during which a part of DON was transferred to the wastes, and another section of DON was degraded during degumming and alkali refining. Moreover, the DON degradation product was identified to be norDON B by using the ultraviolet absorption spectrum, high-performance liquid chromatography (HPLC), ultra-high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF MS), and nuclear magnetic resonance (NMR) methods, and the degradation product was found to be distributed in waste products during oil refining. This study provides a scientific basis and useful reference for the production of non-mycotoxins edible oil by traditional refining.

“…Corn oil contains high levels of unsaturated fatty acids (86%), and the percentage of linoleic acid is about 60%. In addition, corn oil is recognized as an ideal healthcare oil due to the highest level of unsaponifiable matters (1.3%-2.3%) (Stamenković et al, 2020). As the principal unsaponifiable substances, tocopherol and phytosterols play a significant role in regulating the level of cholesterol and preventing cardiovascular diseases (Marinho et al, 2019).…”

Corn wax, as a kind of vegetable wax, is a by-product of the corn oil industry. In this study, the corn wax was purified from the corn oil refineries. The composition and physicochemical properties of corn wax were studied to provide theoretical guidance for the production and application of corn wax. The results showed that the purity of corn wax was higher than 95%, and the corn wax ester ranged from C42 to C58, with C46, C44, and C48 being predominant. The fatty acid carbon atom of corn wax was in the range of 16-30, with higher percentages of C20, C22, and C24. The fatty alcohol of corn wax was in the range of C20-C32 and dominated by C22, C24, C30, and C23. The physicochemical properties of corn wax were also determined and compared with other vegetable and animal waxes to get a more comprehensive understanding of corn wax. The results showed that corn wax was a green and healthy natural resource with great potential for application in food, health care, and medicine.
