Peanut proteins: Extraction, modifications, and applications
Although up to 80%–90% oil can be removed by hot pressing method, most proteins in peanut meal will be denatured and the content of water-soluble proteins and functional properties will be decreased obviously due to high-temperature treatment. The general cold pressing process is processed in an environment below 60 °C.
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
Impact of roasting and extraction methods on chemical
5-Hydroxymethylfurfural (HMF) was extracted from peanut oil by liquid–liquid extraction procedure and determined by HPLC system as described by Durmaz and Gömen . 0.5 g of oil was mixed with 1 ml of methanol (70%) in Eppendorf tube for analysis. The mixture was vortexed for 1 min and centrifuged at 10,000 rpm for 5 min.
Cold pressed peanut meal, also known as defatted peanut meal or pressed peanut meal, is a by-product of peanut oil extraction. It contains a high protein level (> 25%), and is white to creamy in color due to the mild thermal (< 60°C) treatment (Zheng et al., 2013). Cold pressing of 100 kg peanut kernels can generate 70 kg of defatted peanut
Research Advances in the High-Value Utilization of Peanut
Zhao et al. used a commercial protease to hydrolyze hot-pressed peanut meal by enzyme and extract protein, resulting in an increased protein utilization rate of 60.61–67.86%. The DPPH free radical scavenging ability of the enzymatic hydrolysis products from hot-pressed peanut meal was higher than that of low-pressed peanut meal.
The optimal conditions were identified as follows: enzyme amount at 1.7%, hydrolysis time at 3.8 h and 56 °C, materials to water rate at 1:4, pH at 9.3, ultrasonic time at 20 min, and a temperature of 45 °C. This allowed for an oil extraction rate of 88–92% and a protein extraction rate of 95.50 ± 0.44% . The authors did not provide an
Peanut proteins: Extraction, modifications, and applications
The highest protein extraction rate (25.51%) was obtained under the conditions of 1415.43 W.cm⁻², 15 min, pH 10.0, 50°C, and 1% (w/w) alkaline proteinase. and extracted peanut protein with
included a feeding rate of 142 kg/h, dry extrusion at 136–138 for extracting high-quality peanut oil. The cold press extraction method has gained popularity in recent years, primarily due.
- How is cold pressed peanut oil extracted?
- The peanuts are then placed in a conditioning tank, where the pressing temperature and moisture are adjusted to maximize the oil yield. To commercially extract cold-pressed peanut oil, a twin-screw press is used, and the pressing is performed at specific temperatures that do not exceed 60 °C.
- 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.
- What are the optimal conditions for peanut oil extraction?
- The optimal conditions for the extraction process were found to be a pressure of 8000 psi and a temperature of 80 °C. Lower temperatures resulted in decreased extraction rates. Furthermore, a 3-min holding time was the most effective for dissolving peanut oil up to the saturation level in the SC-CO 2 fluid.
- How to extract oil from peanuts?
- Chemical methods of oil extraction from peanuts. 3.1. Organic Solvent Extraction When extracting oil from oilseeds, the organic solvent is used to separate crude vegetable oil from the meal, which contains both proteins and carbohydrates too. The most frequently utilized organic solvent for this process is hexane [ 18, 71 ].
