The road to reuse of walnut by-products: A comprehensive
In addition, Song et al. (2022) summarized the extraction technology of walnut oil and suggested that supercritical extraction could prepare a clearer walnut oil and has a certain refining effect. Meanwhile, the extracted walnut oil has less harmful compounds but more beneficial components, as well as greater photo-oxidative stability.
The reason for the high AV of SCB-walnut oil may be that free fatty acids were more easily dissolved in carbon dioxide. The peroxide values(PV) (0.01–0.04 mg/100 g) obtained from different oil extraction methods for walnut oil were much lower than the recommended levels for commercial edible vegetable oils (≤0.26 mg/100 g).
Extraction, chemical components, bioactive functions
Several findings have indicated that the extraction ratio of walnut oil by cold pressing ranges from 42.72% to 47.04% (W/W) [30]. Another study demonstrated that the optimal extraction conditions for walnut oil by batch flow cold pressing were 10.5 MPa, 31.5 °C, and a sample weight of 8 g, for a yield of 25.36% [30]. In addition, the quality
The optimal extraction conditions of walnut oil by Soxhlet were solid to liquid ratio of 1:7, temperature of 76 °C, time of 4 h, and the extraction efficiency of walnut oil was 58.3%. The

3.3 cold pressed walnut oil edible walnut oil obtained, without altering the oil, by mechanical procedures only, such as . expelling or pressing, without the application of heat. They may have been purified by washing with water, settling, filtering and centrifuging only. 3.4 refined/non-virgin walnut oil
The highest stearic acid (7.69%) was found in cashew oil obtained by cold press. Other fatty acids analyzed in nut oils obtained by two extraction systems were found to be in minor amounts (Table 3). The walnut oil was rich in linoleic acids and other oils higher amount of oleic acid as seen in Table 3. Walnut oil contained the highest level of
Comparison of cold-pressing and soxhlet extraction systems
Antioxidant activities of different nut oils ranged from 11.43 (peanut) to 65.58% (pistachio) in cold pressed oils whereas in case of soxhlet extracted oils they were in the range of 11.32 (hazelnut) to 51.28% (pistachio). β-Carotene contents of oils obtained by cold pressing and soxhlet extraction changed between 7.53 (almond) and 13.58 µg/100 g (pistachio). The highest total phenol
Juglans regia L. commonly known as walnut is used as the most extensive and economical tree in the world. This review aims to study the ethnomedicinal, phytochemical and pharmacological potential of walnut. The literature has been collected from different online sources like science Direct, Scopus, ResearchGate, Google Scholar, PubMed, etc. based on inclusion and exclusion criteria. An
Characteristics and Antioxidant Activity of Walnut Oil Using
The 2.5 g of walnut oil was added to 5 mL of methanol and shaken 3 min in the dark. The supernatant was separated as the polar extract, and the remainder was retained as the nonpolar extract. Approximately 0.12 g of the walnut oil sample was used as a whole oil for the DPPH assay.
underutilized nut found growing as a wild plant most of time in most forest region in Africa. The fruit is a very good source of vitamins, minerals, antioxidants and essential nutrients. The nut offers a good source of carbohydrate, proteins, polyun-saturated acids like α-linolenate an essential fatty acids and calories. These nuts
