Walnut (Juglans regia L.) kernel oil bodies recovered by
The microstructure of the aqueous extracts obtained after grinding in water of walnut kernels was examined by CLSM (Fig. 1).The materials released from the walnut kernels after grinding in water corresponded i) to partially disrupted walnut kernel internal cell compartments containing OBs and protein bodies (PBs), ii) to cell wall fragments, and iii) to OBs and PBs released from the walnut
Gonzalez-Gomez et al. investigated the best settings for enzyme-assisted extraction to produce superior walnut oil and also reported the optimal conditions for walnut oil extraction (pH 4.0, temperature 41.5 °C, and 86 min), with a yield of 75.4%. The enzyme-assisted extraction extracted walnut oil had a five-fold higher antioxidant potential
Investigation on walnut kernel oil extraction using different
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 extraction efficiency of pressing was 43.2%. Walnut oil mainly contains phosphorus, zinc, magnesium, potassium, calcium, and other elements.
Maximum extraction yield and oil solubility in SC CO 2 obtained at 50 MPa, 333 K, 9.00×10 −4 m, 3.33×10 −4 m 3 /h were 0.65 kg oil/kg of dry sample and 37.16 g oil/kg CO 2, respectively. The results obtained in this study showed that the crossover pressure effect of walnut kernel oil was at 30 MPa.
Research progress on Walnut oil: Bioactive compounds, health
Walnut oil is a natural vegetable oil of significant importance due to their nutritional, and intelligence-boosting benefits. Several factors, including the processing parameters and the phytochemical profile, affect walnut oil products’ flavor and color. In addition, storage environment of walnut oil can also affect walnut oil 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
Supercritical fluid extraction of walnut kernel oil
Maximum extraction yield and oil solubility in SC CO2 obtained at 50 MPa, 333 K, 9.00×10−4 m, 3.33×10−4 m3/h were 0.65 kg oil/kg of dry sample and 37.16 g oil/kg CO2, respectively. The
Naturally, the content of walnut oil in saturated fatty acids is low, but higher in polyun-saturated fatty acids, primarily linoleic and linolenic acids (Table1). Oleic acid is the only monounsaturated fatty acid contained in walnut oil [18]. Walnut kernels typically contain 60% oil, which depends on the cultivar and may range from 52% to 70%.
Oxidative Stability of Walnut Kernel and Oil: Chemical ..., MDPI
The impact of storage temperature and time on quality of two walnut cultivars (Juglans regia Chandler and Howard) were evaluated. Free fatty acids, peroxides, and oxidative stabilities exhibited significant changes. After the storage period, γ-, δ-, and α-tocopherols in Howard oil significantly reduced by 42, 56, and 100% at 5 °C, while 23 °C showed 48, 42, and 100% losses, respectively
2.2.1 Cold-press The oil of walnut kernel was obtained by using cold-press extraction process after removing the broken or damaged walnut kernels and other impurities such as stem, and skin as they can have negative effects on the oil quality. Whole kernel was extracted with cold-press（2–6 L/ h capacitywithout heat treatment.
