Effects of plant-scale alkali refining and physical refining
2019. Summary Oilseed rape (Brassica napus) is the third largest source of vegetable oil globally. In addition to food uses, there are industrial applications that exploit the ability of the species to accumulate the very‐long‐chain fatty acid (VLCFA) erucic acid in its seed oil, controlled by orthologues of FATTY ACID ELONGASE 1 (Bna.FAE1.A8 and Bna.FAE1.C3).
Rapeseed oil is a popular edible oil in China, especially in South China, and the consumption of rapeseed oil in 2019–2020 was up to 27.8 million metric tons . Rapeseed oil is consumed less than palm oil and soybean oil, which ranks third in the world . Bioactive compounds and unsaturated fatty acids (USFAs) are abundant in rapeseed oil and
Physical refining of edible oil | Semantic Scholar
Physical refining of edible oils has received renewed interest since the early 1970s when the process was reintroduced on a large scale to refine palm oil in Malaysia. Subsequent laboratory and field tests have also shown that physical refining can be used as a substitute for caustic or chemical refining, not only for high free fatty acid (FFA) oils such as palm, but also on low FFA oils such
Physical Refining Physical refining (Fig. 2) has been known with limited application for many years. The basis of the technique is the use of deodorizers for steam distillation of fatty acids as well as odoriferous volatiles from the oil. In this way, it is possible to eliminate the caustic soda neutralization
Effects of plant-scale alkali refining and physical refining
Some processes were compared with a laboratory oil refining. Crude rapeseed oil contained 656 mg kg−1 of total tocopherols, followed by high oleic sunflower with 373 mg kg−1 of tocopherols and
The objective of such treatments (chemical and physical refining) is to get a better quality, a more acceptable aspect (limpidity), a lighter odor and color, longer stability, and good safety

Chemical and physical refining are two main ways of refining procedures for raw rapeseed oil. One of the most common methods for refining vegetable oils that significantly reduces free fatty acids (FFA), phospholipids, waxes, aldehydes, and ketones is chemical refining. However, physical refining is also extensively utilized. Significant
Physical refining | Journal of the American Oil Chemists' Society
By reviewing current commercial physical refining processes a prospectus is suggested for the future objectives in this field of edible oil processing. The paper reviews widely used physical refining processes for the relatively high free fatty acid (FFA) laurics and palm oil and a commercial operation for physical refining of maize and sunflower oils. In addition, the relatively new departure
2.2.2. Preparation of rapeseed oil by PFLR technology. The process flow of PFLR technology is shown in Fig. 1 (B). Rapeseed crude oil was pressed at 101.3 KPa from the same heat-pretreated rapeseeds by the oil press machine (Xiangju Intelligent Co., Ltd., Dongguan, China) when the squeezing chamber temperature was 130 °C with a loading mass of 200 g each time.
- Does rapeseed oil change chemical properties during refining process?
- A similar trend was observed for the AV, PV and p -AV changes of the oils in varieties during refining process, which indicates that there was no significant difference between these chemical properties of rapeseed oil in varieties.
- Does rapeseed oil have physicochemical properties and oxidative stability?
- Although many researchers have investigated the physicochemical properties of rapeseed oil, there is still a lack of information on the physicochemical properties and oxidative stability as it relates to different rapeseed varieties during refining process.
- How much tocopherol is lost in rapeseed oil?
- Previous study reported the greatest losses of total tocopherol content in oils could be induced by physical refining (deodorization), amounting approximately to 20.2¨C27.1% [ 32 ], and the deodorization step would cause 7¨C90% losses of tocopherols in rapeseed oils [ 33 ].
- Can rapeseed oil be used as a functional oil?
- Thus, CPRO is suggested to use as functional oil as it contains high amounts of phenolic, tocopherol, and phytosterol. The antioxidant activity of CPRO is higher than refined rapeseed oil due to the preserved bioactive compounds in CPRO, as shown by the DPPH assay in Siger et al. (2005).
- What are rapeseed oil tocopherols?
- They (¦Á, ¦Ã, and ¦Ä) are potent natural antioxidants that can inhibit the deterioration of oils during storage and prolong the shelf life of edible oils [ 29 ]. Fig 5 showed total and individual tocopherol contents of different rapeseed oil varieties at each step of refining process.
- What is a good refining method for rapeseed oil?
- Silicon dioxide had the best refining effect, with dephosphorization and deacidification rates of 95% and 42%, respectively, when the dosage was 30 g/kg at a squeezing chamber temperature of 130 °C. At the same time, the L* value of rapeseed oil increased by 21%, and the a* value decreased by 59%.
