Random Surface Methodology: Process Optimization for Peanut Oil
To optimize this process, the effects of ultrasonic time (0–70 min), cellulase enzyme concentration (0–2%) and pH (4–5.5) are investigated on peanut oil extraction yield (EY) as well as the
Generally, peanut by-products are mainly produced from oil extraction processes including peanut flour, peanut skins and shells which have potential application many disciplines due to their reach functional compounds such as protein, fiber and polyphenolics (Zhao et al., 2012); I) Peanut flour, the by-product generated during oil extraction, benefits high quality digestible protein
Defatting and Defatted Peanuts: A Critical Review on Methods of Oil
Peanuts, being crucial crops of global importance, have gained widespread recognition for their versatility and nutritional value. 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 processes. As a result of the first process, a solid matrix is generated
Value of import of edible oil in USD in Ethiopia 2012–2018. Display full size. The current demand of vegetable oil is 686,400,000 liters per year and will increase as the population increases at a rate of 2.3% per annum. Of the total demand of 686,400,000 liters of edible oil, 604,032,000 liters is to be imported.
Efficiency of the use of solvents in vegetable oil extraction
It was found higher peanut oil content (43.49%), extracted with petroleum ether solvent with moist grains (6.69%), which increase in the extracted oil content was 8.85%. However, [12] with moist grains (6.33%) and extraction with hexane observed higher oil content in peanuts, corroborating to [13] , with extraction without grains moisture observed higher oil content, independent of the solvent
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.
Experimental Comparison between Ethanol and Hexane as Solvents for Oil
Thus, to compare the oils extracted with Hx and Et relative to the oil from the mechanical pressing of the peanut grains, in addition to comparing the defatted solids obtained from the extraction with the solvents, further characterizations of the oils and DSs were performed, as presented in Section 3.4 and Section 3.5.
However, higher BI was observed in oils extracted from peanut roasted at 180 °C for 10 min (Fig. 1). The HPLC analyses of peanut oils indicated that HMF increases at a higher roasting temperature in a time-dependent manner. MRPs (HMF and furfural derivatives) formed during roasting are responsible for the browning of oils (Cai et al. 2013).
- Is oil extraction from peanuts environmentally friendly and cost-efficient?
- A comparison in terms of productivity, efficacy, specificity, quality of the extracts, and operating conditions was conducted, which favored the novel methods as being mostly environmentally friendly and cost-efficient. Chemical methods of oil extraction from peanuts.
- Why is US pretreatment used in the extraction of peanut oil & proteins?
- US pretreatment technique can be applied for the extraction of peanut oil and proteins to improve their heat-induced gelation properties by modifying their molecular structure to the denser and more homogeneous network (more stable) which is less sensitive to enzyme hydrolysis ( Fig. 13 ).
- How is peanut oil extracted?
- Peanut oil is typically isolated from peanuts using conventional extraction methods, such as mechanical pressing and solvent ( n -hexane) extraction [ 29 ]. However, many of the peanut proteins are denatured as a result of high temperatures during pressing or due to exposure to the organic solvent.
- How can aqueous enzymatic extraction improve the function of Peanut proteins?
- Discuss extraction methods, modifications and applications of peanut proteins. Aqueous enzymatic extraction can efficiently separate oils and peanut proteins. The functionality of peanut proteins was significantly improved after modification. Native and modified peanut proteins can be used for a variety of purposes in foods.
