Fate of phospholipids during aqueous extraction processing of peanut
Phosphorus content of commercial peanut oils. Phosphorus contents of 5 kinds of commercial peanut oil were shown in Table 3. Commercial oil A, B and C were produced by hot-pressing while commercial oil D and E were produced by cold-pressing.
Background Phosphorus (P) is one of the most essential macronutrients for crops. The growth and yield of peanut (Arachis hypogaea L.) are always limited by P deficiency. However, the transcriptional and metabolic regulatory mechanisms were less studied. In this study, valuable phenotype, transcriptome and metabolome data were analyzed to illustrate the regulatory mechanisms of peanut under P
Fate of Phospholipids during Aqueous Extraction Processing of Peanut
After oil extraction, defatted peanut is a protein-rich byproduct The hydration at 95°C with 2% water for a contact time of 15 min resulted in maximum removal of phosphorus of the oil with
2 Chemical Composition and Bioactive Compounds of Extracts from Peanut Oil-Processing By-Products. The edible kernel comprised about 68–72% of the peanut, while the balance 28–32% is the peanut hull [ 8 ]. Peanut kernel’s average thickness, width, and length are 6.9 mm, 3.6 mm, and 8.5 mm, respectively [ 9 ].
Study on Extraction of Peanut Protein and Oil Bodies by Aqueous
In their experiment, the authors used alcalase 2.4 L an enzyme-to-substrate ratio of 1%, and an incubation time of 9 h at 45 • C. Using these conditions, an oil yield of 91.98% was attained [77].
The adverse environmental impacts of conventional oil processing technologies have forced the development of new green technologies. The aqueous enzymatic extraction (AEE) destroys the oilseed through enzymatic hydrolysis and separates the oil and hydrophilic components with water, to achieve simultaneous separation of oil and protein etc.
Aqueous Enzymatic Extraction of Oil and Protein Hydrolysates from
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
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.
- What factors affect peanut oil and protein quality?
- It is important to note that factors during the extraction process (like pH value, ionic strength, and temperature) can directly affect peanut oil and protein quality by influencing on the composition, structure, physicochemical properties, and functional properties.
- How does surface temperature affect the quality of peanut kernels?
- It can be said that preferred physical and microbiological quality characteristics of peanut kernel relate to surface temperature, for instance processing time during pulsed infrared roasting lead to the decrease in hardness ( Wassell et al., 2002 ). 5. Effect of storage conditions on the peanut compositions
- 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 to prevent oxidation process in Peanuts?
- Coating process in peanuts is another way for preventing or delaying oxidation process which corresponds to thin layers of edible materials onto the surface (act as skin) and may prevent moisture loss and oxygen diffusion ( Atarés et al., 2016 ).
