Soak fresh walnut kernels as a natural antioxidant. The content of nutrient in walnut kernels was almost constant and the antioxidant capacity of fresh walnut kernels was significantly enhanced. Chatrabnous et al. (2018) Add to sunflower oil as an antioxidant. The oxidation reaction of sunflower oil was substantially slower. Noshirvani et al

Soxhlet assisted oil extraction. The nut kernels were extracted using a Soxhlet Apparatus with petroleum ether for 5 h. The solvent was removed with a rotary vacuum evaporator at 50 °C. The separated oil was kept in colored glass bottles at − 18 °C till analysis (AOAC 1990).

Walnut Kernels Walnut kernels originating in the Czech Republic were purchased in the supermarket chain, mixed together vacuum-packed and stored at 4 ℃ in dark place. Prior pressing, the water content in the kernels was assessed (2.95 ± 0.21%). Kernels were ground in a stainless-steel mill to the fraction of the size from 0 mm to 6 mm.

What are the three processes used to extract walnut oil?
Typically, three processes were used: solvent extraction, pressing, or super critical extraction. For the sake of simplicity, or for its better selectivity toward lipids, solvent extraction was often used to obtain walnut oil and analyse it chemically.
How do walnut oil extraction processes differ?
The walnut oil extraction processes used differed according to the research objective: (i) determination of walnut oil content, (ii) selection of certain compounds of interest, (iii) implementation of new systems in industrial installations to increase oil yield, to obtain oil free from oxidized products or to promote an eco-friendly technique.
Why is extraction technology important for walnut by-products?
Extraction technology is very important for walnut by-products to obtain beneficial compounds. In general, chemical, physical, and biological methods were either separately used or adopted with other modern technologies to assist the extraction efficiency of target compounds. 3.1. Conventional extraction methods 3.1.1. Solvent extraction
How to obtain defatted walnut oil?
Therefore, screw pressing is considered as the most suitable technology for obtaining defatted WM. 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.
How is polar lipids extracted from walnut kernels?
Table 6. Pigment contents (mg/kg) in oil according to walnut variety. N: sample number. 15.2. Polar lipids Oil was extracted from crushed walnut kernels by solvent extraction (petroleum ether, then methanol or chloroform / methanol).
Does roasting Walnut before extracting walnut oil affect nutritional composition?
For instance, roasting walnut before extracting walnut oil, cold pressing or supercritical extraction of walnut have direct effects on the nutritional composition and color of walnut oil and walnut by-products.
