Soapstock and deodorizer distillates
This route is the least e铿僣ient. Two research groups have found that for an initial mixture of soybean oil deodorizer distillate, the conversion was approximately 63% (Haas & Scott, 1996; Tuter et al., 2004) and using a

Extraction of tocopherols from the deodorized distillate of soybean oil
Nov 1, 2003LPG was chosen as extraction solvent in order to improve extract recovery and prevent tocopherol degradation. separation of free fatty acids from soybean oil deodorizer distillate
The soybean oil corresp onds from 20 to 30% of the vegetable oils world market (Bockisch, 1998) and its producti on involves several steps that are necessary to render the soybean oil suitable for
- Can deep eutectic solvents extract natural tocopherol from deodorized distillates?
- However, the extraction of natural tocopherol from deodor-ized distillates using deep eutectic solvents as extractants have not been extensively studied. The extraction of tocols from crude palm oil using choline-based DESs was pro-posed in a recent report27).
- How to get more natural tocopherols from deodorizer distillate?
- In order to obtain more natural tocopherols, the natural tocopherols obtained from the deodorizer distillate have been extensively studied. Nowadays, the main industrial method of recovering tocopherol from deodorizer distillate is molecular distillation7, 8).
- What are the - tocopherols in neutralized soybean oil?
- In neutralized soybean oil, the concentrations of α-, β-, γ-, and δ-tocopherols were found to be 510.20, 55.12, 598.67, and 108.32 mg/kg, respectively. In comparison to the present study, lower concentrations of α-, β-, γ-, and δ-tocopherols were reported in the neutralization step, 434.3, 38.5, 502.5, and 117.0 mg/kg, respectively.
- How to recover tocopherol from deodorizer distillate?
- Nowadays, the main industrial method of recovering tocopherol from deodorizer distillate is molecular distillation7, 8). Although molecular distillation can obtain tocopherol with higher purity, it has low separa-tion efficiency and harsh operating conditions such as high temperature and high vacuum.
- Are and tocopherols found in refined soybean oil?
- Figure 1 shows the representative chromatogram of individual separation of tocopherols of refined soybean oil. According to the NP-HPLC analysis, results show that α- and γ-tocopherols were found in higher concentrations in soybean crude oil and smaller concentration in deodorized oil.
- How are tocopherols extracted from Sodd?
- Firstly, total tocopherols were extracted from SODD at room temperature by phenolic deep eutectic solvent composed of ChCl and p-cresol. Subsequently, tocopherols were successfully separated from deep eutectic solvent phase by re-extraction with n-hexane, and tocopherols products could be simply recovered.
