Production, Processing, and Food Uses of Peanut Oilseed, Oil,
In 2018, peanut oil sold for US$1470/MT in the United States and for US$1326 in Rotterdam. Peanut oil is recovered primarily by expeller pressing or in combination with hexane extraction. Only four plants process peanut oil in the United States. Peanut oil is processed by conventional caustic refining, adsorbent bleaching, and deodorization.
Sunflower oil, soybean oil, palm oil, rapeseed oil and peanut oil are commonly used in cooking [70]. During cooking, oil is added to food to give it taste, colour and fragrance. However, the high temperature and length of the cooking process will not only destroy the unsaturated fatty acids and trace active substances but also lead to the oxidation of the oils into primary or secondary
Chemical vs. Enzymatic Refining to Produce Peanut Oil for Edible Use
Regarding the toxicity towards S. zeamais, the crude peanut oil and the chemically refined peanut oil had lower LC 50 values (1.836 and 1.372 g kg −1, respectively) than the oils rectified through enzymatic degumming (LC 50 from 2.453 to 4.076 g kg −1), and, therefore, they can be suggested as sustainable stored grain protectants.
According t o this, the highest oil yield was ac h ieved in solvent extraction w ith hegza n, followed by supercritical CO 2 extraction and the minimum efficiency was achieved by cold press m ethod.
Peanut Oil Processing Technology
Production Line Process. 1. Cold-Pressed Peanut Oil. First, the sheller is used to shell the peanuts, and then the peanut kernels are transported to be dried in the low-temperature drying oven after being subjected to precleaning, cleaning by the gravity/magnetic separation destoner, and grading.
The USDA tracks the production of nine major vegetable oils. In 2018, worldwide production of vegetable oils was 203.3 MMT of which peanut totaled 5.8 MMT or 2.9% of the total production. Protein
Edible Oil Refining Process - Silverson
Phosphoric acid is most commonly used, although citric acid is suitable for some oils. Process temperature is typically in the range of 120 - 160ºF (50 - 70ºC). Neutralization process temperature may be higher, up to 200ºF (95ºC). The strength of the sodium hydroxide solution varies according to the acid content and oil type.
We can provide edible oil refining plant equipment with capacity ranging from 50 t/d to 4,000 t/d for soybean oil, rapeseed oil, sunflower seed oil, cottonseed oil, rice bran oil, palm oil, corn oil, peanut oil, linseed oil, animal fats and oils, chicken fat, butter, fish oil and etc. Refining is the last step in edible oil processing.
