Refining Vegetable Oils: Chemical and Physical Refining - PMC
The bleaching is a critical step in the refining process of oils [ 57, 58 ], preceded generally by degumming, neutralization, and drying processes. Bleaching is a complex physical and chemical process employed in the refining of vegetable oils. The objective of bleaching (or decolorizing) is to reduce the levels of colored pigments (carotenoids
The effect of the industrial chemical refining process on the physicochemical properties, fatty acid composition, and bioactive minor components of peanut oil was studied. The results showed that the moisture and volatile matter content, acid value, peroxide value, and p-anisidine value were significantly changed (P 0.
Processing and Food Uses of Peanut Oil and Protein
It is well recognized that crude soybean oil (a high gum oil with 2–3% phosphatides) is more stable than refined oil where the phosphatide content has been essentially removed (Going, 1968). The oxidative deterioration of peanut lipids (whole peanuts) has been investigated by a number of laboratories ( Brown et al., 1974 , Davis, 1961
Regarding the toxicity towards S. zeamais, the crude peanut oil and the chemically refined peanut oil had lower LC50 values (1.836 and 1.372 g kg−1, respectively) than the oils rectified through enzymatic degumming (LC50 from 2.453 to 4.076 g kg−1), and, therefore, they can be suggested as sustainable stored grain protectants.
Formation and reduction of 3-monochloropropane-1,2-diol
Peanut shell and inner skin were removed before crude oil producing. 2.2. Laboratory scale refining process. The refining process started with degumming. The crude oil was filtered, degummed by adding 0.15% phosphoric acid (w/w) and 5% hot water (85 °C) (W/W), stirred for 30 min at 85 °C and then the mixture was reduced to 75 °C.
Crude peanut oil, i.e. unrefined, was mechanically expressed using a lab scale Carver Press or received from a commercial supplier. Peanuts, including two commercial lots of normal oleic peanuts, and several high oleic accessions from the 2011 Uniform Peanut Performance Tests (UPPT) program, were utilized to prepare the 16 test samples ().
Formation and reduction of 3-monochloropropane-1,2-diol
As shown in Table 1, deodorization was a critical factor that influenced the formation of 3-MCPD esters in peanut oil among the refining steps. In order to examine if there were any differences in the contents of 3-MCPD esters between different ways of oil production, hot pressing and solvent extracting were introduced for crude oil production.
Northstar is a very light paraffinic crude oil with a density of 0.779 g/ml (API° 50), and exhibits low content of wax (1.7 wt. %) and asphaltenes (0.03 wt. %). The oil is a low-emulsifying crude oil that forms loose emulsions and easily released water with the addition of a concentration of 500 ppm of the emulsion breaker (Alcopol O 60 %).
- 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.
- Can crude oil be consumed directly?
- Usually, apart from virgin oils, crude oils cannot be consumed directly or incorporated into various food applications without technological treatments (refining). Indeed, crude oils like soybean, rapeseed, palm, corn, and sunflower oils must be purified or refined before consumption.
- Does Physical refining of crude oil reduce Liquid effluents generation?
- General overview of the chemical and physical refining process of crude oil. Physical refining of crude oils, therefore, overcomes the disadvantages of neutralization by sodium hydroxide [ 75 ]. Indeed, this process, which is deemed to be eco-friendly, minimizes liquid effluents generation [ 29, 30 ].
- What is crude oil refining?
- Treatment that eliminates undesirable and toxic components in crude oils is known as ¡°refining¡± [ 9 ]. Refining is practically mandatory for crude oils that cannot be consumed as virgin oils to provide a product with an attractive appearance, a neutral taste, and more resistance to oxidation.
