The solvent extraction of peanut oil is a process of extracting peanut oil with n-hexane as extraction solvent. The process consists of four systems: solvent extraction system, wet meal desolventizing system, mixed oil evaporation system, and solvent condensation recovery system. Here I will introduce how these systems works.

In this experiment we use hexane to extract peanut oil; however we will not recover used hexane. Keep in mind that peanuts contain oil (similar to the vegetable oil in Part I) and insoluble matter like protein (a polymer synthesized from amino acids). Procedure: Get about 50 grams of dry-roasted peanut, peal the outer shell and remove the seeds.

Edible peanut protein hydrolysates were produced upon oil extraction from peanuts using an aqueous extraction process assisted by the enzyme alcalase 2.4 L . The study employed optimal conditions, including a pH of 8.5, a temperature of 60 °C, an enzyme content of 1.5%, and an 8 h incubation period, which resulted in an oil yield of 91.7 ± 1.

In addition to direct consumption, either with or without treatment, peanuts can be the subject of diverse applications focusing mainly on two distinct objectives: oil extraction and defatting

Peanuts are commonly eaten as a snack or processed into peanut butter, while more than 70% of the harvest is used for oil extraction . Indeed, peanuts contain between 45.9% and 55.4% of lipids that are specifically high in essential polyunsaturated fatty acids [ 5 ] [ 6 ] [ 7 ] .

Table 2 shows the experimental data for the continuous downward extraction of peanut oil from peanuts using n-hexane. According to literature n-hexane is widely used in the food industry for extraction of oils because it is considered to be the most cost-effective method asit gives a production of residual oil below 1%.

According to the FDA some hexane remains in the oil as “residue” and in 2009 the Cornucopia Institute fond that hexane residues are in Soybean, Canola, Peanut and other oils. Mazola and Crisco brands openly admit to using both GMO ingredients and hexane extraction in their processing.

1. The SOLTEQ solid-liquid extraction unit (Model: BP 40) can operate as a fixed-bed extractor in either batch or continuous mode. It uses a packed column, condenser, and pre-heater to extract solutes from solids using solvent. 2. An experiment was conducted to investigate the effect of solvent flow rate on continuous downward extraction of peanut oil from peanuts using n-hexane solvent

A mass balance on the oil in the solid peanut phase can be derived for this system using a model that assumes no concentration gradient is present through the bed of peanuts. p L (Oil sc Oil Oil.
