Refining Vegetable Oils: Chemical and Physical Refining
So, tocopherols decrease in vegetable oils substantially and directly influence decrease in the shelf life of oils and the nutritional quality [20, 22]. In this context, such refining process for crude oils should be undertaken with the aim of removing undesirable compounds and avoiding the least possible damage to desirable components [14, 23].
These can directly influence the safety level of refined oils. Several studies were devoted to determining the effects of refining on the minor bioactive components such as sterols and tocopherols. Indeed, Verhé et al. [22], who found a sterols loss of 10–32% (physical refining) and 13–31% (chemical refining).
Edible vegetable oils from oil crops: Preparation, refining
Refining of vegetable oils. The refining process can remove many undesirable components, including free fatty acids, oxidation products and photosensitizers. It is worth noting that some beneficial components are also removed, such as carotenoids (mainly including α- and β-carotene) and tocopherols (such as tocols and tocotrienols) [45].
However, this refining process needs to be tailored as the composition of crude oil is highly variable, depending upon the plant/fish species, geographical location of the source and method of oil
Refining Vegetable Oils: Chemical and Physical Refining
two main industrial technologies used for vegetable oils’. rening, namely, chemical rening and physical rening. Chemical rening removes free fatty acids by soda neu-. tralization
In edible oil refining, the continuous effort to reduce overall production costs is mainly achieved by increasing plant capacities, installation of mono feedstock plants, and increasing the degree of automation. Over the years, more energy-efficient processes and technologies, resulting in a higher refined oil yield, have gradually been introduced.
A Review on Vegetable Oil Refining: Process, Advances and Value
Nowadays, consumer food choices are driven by health awareness and sustainability concerns. As vegetable oil is an important component of the human diet, the source and the processing play an important role in consumer acceptability. To remove impurities that affect the color, palatability, stability, and safety of oil, crude vegetable oil must be refined. This review highlights the processes
2. ELIMINATION OF UNDESIRABLE COMPOUNDS FROM EDIBLES OILS 2.1. Edibles Oils Refining Crude vegetable oils are produced during the process of oilseeds trituration. This operation, which has only changed relatively a little during the pass sixty (60) years, has three main stages (Evrard et al., 2007; Bauer et al., 2010; Fine et al., 2016).
Phytosterols in edible oil: Distribution, analysis and variation during
2. Phytosterols distribution in edible oil. Phytosterols can be detected in various plants and edible oils, such as cereal, fruits and vegetable oils. Among these products, the highest content of total phytosterols was found in vegetable oil (150–1,231 mg/100 g), followed by legumes, nuts and cereals [16, 17].
The most commonly tocopherols found in vegetable oils were α- and γ-tocopherols. Soybean contains 1328 mg/kg tocopherol, which is highest among plant oils. Total tocopherol contents gradually decreased until the end of the refining processes in all oil types. The content of α-, β-, γ- and δ-tocopherols also decreased during refining.
- Which industrial technologies are used for vegetable oils' refining?
- The present review aimed at comparing the two main industrial technologies used for vegetable oils¡¯ refining, namely, chemical refining and physical refining. Chemical refining removes free fatty acids by soda neutralization.
- What is vegetable oil refining?
- As vegetable oil is an important component of the human diet, the source and the processing play an important role in consumer acceptability. To remove impurities that affect the color, palatability, stability, and safety of oil, crude vegetable oil must be refined. This review highlights the processes and steps used in vegetable oil refining.
- What is alkaline refining?
- This alkaline refining process is applicable for majority of the crude oils, including oils with low quality, except for castor oil (Zeldenrust 2020).
- Which vegetable oil meets the specification?
- Vegetable oils that met the specification include palm oil, palm kernel oil and olive oil. In physical refining of palm oil, the CPO is degummed by mixing with 0.04¨C0.1% phosphoric acid (conc. 85%) for about 5¨C20 min. Subsequently, the degummed oils were bleached using around 1¨C2% of bleaching earth under vacuum at a temperature of 95¨C120 °C.
