“…The relative contents of PUFAs (9,12-octadecadienoic acid) in the yellow horn oil extracted by ASP–MAE was 47.35% ± 3.79% in this study (Table 4). Moreover, current literature [13] indicates that yellow horn oil contains α-, γ-, and δ-tocopherols, of which γ-tocopherol is the major tocopherol, and the total tocopherol content is 83.28–106.27 mg/100 g for various extraction methods. The antioxidant activity of tocopherols is mainly attributed to their ability to donate hydrogen atoms to free radicals, thus inhibiting lipid oxidation.…”

This study investigates an aqueous salt process (ASP) combined with microwave-assisted extraction (MAE) for the seed oil extraction from yellow horn (Xanthoceras sorbifolium Bunge). The NaCl concentration in the oil extraction process affected the oil extraction yield. Box–Behnken design (BBD) and response surface methodology (RSM) were used to optimize the extraction process. The optimal operating parameters were: 24 g/L NaCl, 300 W microwave power, 4:1 water to material ratio, an 80 min extraction time, and 45 °C extraction temperature. The chemical composition of the extracted seed oil was analyzed using gas chromatography–mass spectrometry (GC-MS). This extraction technique for yellow horn seed oil provided high throughput and high-quality oil. The present research offers a kind of green extraction method for edible oil in the food industry.

IntroductionFlaxseed Linum usitatissimum L. is a potential oilseed crop and widely planted in China, North America, Ethiopia and India. Flaxseed contains 30-40 of oil 1 . It has been reported that daily intake of flaxseed oil can reduce the risk of colon tumors, mammary cancer, atherosclerosis, etc. 2 . The efficacy of flaxseed oil is mainly attributed to the richness in unsaturated fatty acids, especially α-linolenic acid ALA 18:3, n-3 , which accounts for 40-68 3 . The consumption of flaxseed oil helps to balance the proportion of n-3 and n-6 fatty acids in the human diet 4 . Flaxseed oil has been considered a healthy oil for its nutritional and pharmaceutical value.Mechanical pressing and organic solvent extraction are the two most common methods for vegetable oil production. However, organic solvent extraction is unacceptable on account of the inevitable residual solvent that is harmful to human health 5 . While mechanical pressing is high energy consumption and low extraction rate 6 . Supercritical CO 2 extraction seems to be an innovative and acceptable method because it is non-toxic, organic solvents-free, and allows more selectivity for target production. However, it is suffering from some serious problems such as high operating pressure, high cost of instrument, and limited production capacity 7 . Compared with supercritical CO 2 extraction, subcritical fluid extraction has advantages of mild

“…Recently, many studies with respect to new types of oil have been carried out. They usually focus on the preparation methods, physicochemical properties, antioxidant properties, nutritional properties, and applications of oils [22][23][24][25][26][27][28][29][30][31]. As a result, the information about tocols in new types of vegetable oil is severely scarce.…”

The consumption of vegetable oil is an important way for the body to obtain tocols. However, the impact of oil types and grades on the tocopherol and tocotrienol contents in vegetable oils is unclear. In this study, nine types of traditional edible oils and ten types of self-produced new types of vegetable oil were used to analyze eight kinds of tocols. The results showed that the oil types exerted a great impact on the tocol content of traditional edible oils. Soybean oils, corn oils, and rapeseed oils all could be well distinguished from sunflower oils. Both sunflower oils and cotton seed oils showed major differences from camellia oils as well as sesame oils. Among them, rice bran oils contained the most abundant types of tocols. New types of oil, especially sacha inchi oil, have provided a new approach to obtaining oils with a high tocol content. Oil refinement leads to the loss of tocols in vegetable oil, and the degree of oil refinement determines the oil grade. However, the oil grade could not imply the final tocol content in oil from market. This study could be beneficial for the oil industry and dietary nutrition.
