Impact of roasting and extraction methods on chemical
Dry air roasting and oil extraction. 250 g of peanuts were roasted in an air fryer (Philips, India) at temperatures of 140, 160 and 180 °C for 5 and 10 min, respectively in the triplicate set. After roasting, peanuts were allowed to cool to room temperature and stored in polyethylene bags at 4 °C until further processed.
The defatting ratio is the oil extraction yield, which is the ratio of extracted oil to the total oil that is initially present in peanut seeds before pressing. The mass of extracted oil is the difference between the initial oil content and the residual oil in the cake, which was determined by Soxhlet extraction (as shown in Section 2.6.1 ).
Peanut proteins: Extraction, modifications, and applications
The yield of free oil extracted from roasted peanut (150 °C, 20 min) using the AEP method was around 92.2% using the optimized processing conditions: solids-to-liquid ratio = 1:5; pH = 9; temperature = 60 °C, and time = 2 h [33]. Liu et al. (2020) investigated a combination of AEP and membrane separation for peanut protein extraction.
The objectives of this study were: (i) to evaluate the effect of particle size distribution on the oil and protein extraction yields when using AEP; (ii) to study the effect of roasting temperature on oil and protein extraction yields when using AEP; (iii) and to show the location of oil and protein in the raw and roasted peanut starting materials which were obtained from high speed universal
Defatting and Defatted Peanuts: A Critical Review on Methods
2. Mechanical Methods of Oil Extraction from Peanuts Mechanical techniques for oil extraction from peanuts are grouped into three main sections: extrusion and screw pressing, cold pressing, and hydraulic pressing. Table1show-cases all these mechanical methods employed, along with their experimental conditions,
The results showed that peanut oil and protein extraction rates peaked at 90 °C, 92.21%, and 77.02%, respectively. The roasting temperature did not change OBE composition but affected its stability.
Effects of Roasting Temperatures on Peanut Oil and Protein
Oil body emulsions (OBEs) affect the final oil yield as an intermediate in the concurrent peanut oil and protein extraction process using an aqueous enzyme extraction (AEE) method. Roasting temperature promotes peanut cell structure breakdown, affecting OBE composition and stability and improving peanut oil and protein extraction rates. Therefore, this study aimed to investigate the effects of
2.2. Aqueous Enzymatic Extraction of Peanut Oil and Protein Peanut oil and protein were prepared using the methods described by Liu [18] and Zhao et al. [19] with minor modiÞ cations. Figure 1 presents a ß owchart of the AEE for peanut oil and protein. For the de-red-coating treatment, the peanuts were roasted in an
Bioactive Phytochemicals from Peanut Oil Processing By
The peanut kernel is primarily used for cooking oil, peanut butter, flour, snack, soup, and dessert. Worldwide, peanut oil accounts for nearly 5.77 million metric tonnes [ 3 ]. The main peanut processing is crushing for oil, contributing to approximately two-thirds of the world’s peanut production, while the remaining is used in food
Using the same seed-roasting temperature (190 °C), quality attributes such as color, acid and peroxide values, phosphorus content and oxidative stability of the enzyme-extracted oil were better than those of the oil obtained by an expeller. After the peanut seeds were roasted at 190 °C for 20 min, with a seeds-to-water ratio of 1:5, an enzyme
