Thermoanalysis of soybean oil extracted by two methods

The degummed oil presented a higher initial temperature than soybean oil extracted by solvent and press, indicating that the lecithins reduced the oil's thermal stability. The lecithins obtained from press-extracted oil presented an area of 87.3, while those obtained from solvent-extracted oil showed an area of 82.9, suggesting the former method produced a larger quantity of this substance.

Soybean Oil an overview ScienceDirect Topics

Soybean oil monoglyceride methacrylates (SOGLYME) were synthesized by E. Can [65, 66]).Soybean oil monoglyceride methacrylates were prepared in a two-step process. First soybean oil was glycerolized in the presence of Ca(OH) 2 as a catalyst at 230–240°C for 5 h. The glycerolysis of soybean oil under these conditions gives a product with an equilibrium mixture containing the monoglycerides

Soybean Wikipedia

To extract soybean oil from seed, the soybeans are cracked, adjusted for moisture content, rolled into flakes and solvent-extracted with commercial hexane. The oil is then refined, blended for different applications, and sometimes hydrogenated. Soybean oils, both liquid and partially hydrogenated, are exported abroad, sold as "vegetable oil", or end up in a wide variety of processed foods.

Comparison of the Oxidative Stability and Antioxidant

We investigated the potential of two oil extracts from seeds of Colliguaya integerrima (CIO) and Cynara cardunculus (CO) to use as nutritionally edible oils. For this purpose, oil quality was accessed by determining the fatty acid composition, peroxide value, acid value, iodine value, saponification number, phenolic contents, and oxidative stability during thermally induced oxidation of

Production of omega 3-rich oils from underutilized chia

In this work, two batches of chia seeds with different oil content (LOCS vs. HOCS) were compared for their oil extraction yield as well as their lipid composition, by using two environment-friendly techniques (SFE and PLE). At 60 °C, pressurized food-grade ethanol allowed to achieve oil recoveries close to 100% in 10 min for both seed types. By SFE, the greatest oil extraction yield was

The thermal analysis of the Jatropha oils exhibited two maximum exothermic peaks (Table 4, Figure 3) with oxidation starting at 162-170°C, within the range reported for edible oils (130-180°C). The significantly higher onset (p < 0.05) and oxidation temperatures (p < 0.0005) of cinerea oil indicated its higher instability due to the highest unsaturated fatty acid content compared to other

Extraction method. There are several types of plant oils, For instance, palm oil is extracted from palm fruits, while soybean oil is extracted from soybean seeds. Vegetable oils may also be classified by grouping oils extracted from similar plants, such as "nut oils". Although most plants contain some oil, only the oil from certain major oil crops complemented by a few dozen minor oil
