Basic introduction of walnut oil in China

Wild walnuts are not as good as artificially planted walnuts. 10 pounds of walnuts may not necessarily produce 1 pound of walnut oil, and the saturation and oil yield may vary depending on the weather conditions each year.

. Walnuts have a high oil content of 65% to 70%, and are known as the "tree oil depot" due to their superior woody oil content. Use modern technology to extract its essence, select high-quality walnuts as raw materials, and use international leading technology to produce natural fruit oil juice. In the international market, walnut oil is known as the "Eastern olive oil" and is highly favored by consumers, just like olive oil

3. Walnut oil has beauty and beauty benefits: This is because walnut oil is rich in essential fatty acids for the human body, as well as a type of shark oil that has a strong affinity with the skin. These two substances can be quickly absorbed by the skin, effectively protecting the elasticity and moisturizing of the skin; Can eliminate facial wrinkles and prevent skin aging<4. Walnut oil has a beautiful and hair care effect: Eating more walnut oil can promote children's hair to turn black<5. Walnut oil has a brain nourishing effect: Walnut oil does not contain cholesterol and can effectively prevent the occurrence of Alzheimer's disease in the elderly; Rich linoleic acid and linolenic acid can eliminate impurities in the metabolism of blood vessels, purify the blood, and provide fresh blood for the brain

Fresh and pure, nutritious, with a light taste and a fatty acid configuration similar to breast milk. It has a light and odorless taste, pure natural flavor, and is easy to digest and absorb. It is a high-end health edible oil for children's development, women's pregnancy, and postpartum recovery

The production method of walnut oil in China

Due to the high oil content of walnut crystals, pre pressing and leaching processes must be used, and the oil press used is generally a hydraulic oil press

1. Pre pressing: First, lay a textile bag flat on the utensil, put in an appropriate amount of walnut kernels, package the walnut kernels into small packages (5 kilograms per package is most suitable), and put the packaged walnut kernels into a specially designed mold (the mold has many holes for oil flow, and the mold should have a suitable thickness to withstand certain pressure). Each layer of material should be separated by thin iron sheets to facilitate the flow of oil between layers. Then increase the pressure, and when the pressure rises to 4 megapascals, oil begins to flow out; When the pressure rises to 10 megapascals, there is very little walnut oil flowing out, and the pressure can be released and discharged. The key point is that the smaller the package, the higher the oil yield; The pressure should be increased less and more frequently, and should not be increased too much at once, otherwise the oil will easily spray out in a slurry or the oil flow channels between the oil materials will be closed and contracted, resulting in a decrease in oil output rate. During the entire oil extraction process, walnut kernels are not heated and do not undergo thermal denaturation. The extracted walnut oil is light in color and transparent, with an oil yield of about 32% of the kernel weight. Walnut cake is in a semi defatted state, loose and has the inherent fragrance of walnuts. It is also protein invariant, making it easy to develop and utilize walnut protein

2. After crushing and pressing, the walnut kernels have undergone structural changes due to external forces. They are then processed by a crusher and broken into small pieces, which is beneficial for rolling. Require small powder size, particle size that meets the rolling conditions, and easy feeding for the rolling machine

3. Rolling is a very important process that directly affects the leaching effect. The walnut kernels produced by rolling have a certain toughness in their external structure, low powder content, and are suitable for extraction conditions. During extraction, the solvent is prone to penetrate into the interior of the meal, resulting in low residual oil

4. Low temperature solvent leaching. The properties of the solvent determine that the leaching device is a tank type leaching device, with a loading capacity of about 65% and a material to solvent ratio of 1:1. The leaching and desolvation of materials are carried out in the same equipment

Tasting and Eating Methods of Chinese Walnut Oil

Babies with constipation should eat it raw on an empty stomach in the morning, from youngest to oldest. Gradually increase according to age. Low temperature cooking or direct use, eat up to 5ML raw on an empty stomach

1. Cooking: Mix with other blended oils in a 1:4 ratio and do not use high heat! The temperature should be controlled below 160 degrees, which means the oil should be 80% hot

2. Mixed dishes: such as cucumber, pineapple, etc., stir directly in the dish

3. Add to mixed drinks: such as adding to milk, yogurt, honey, and juice for consumption together

4. Add it to the prepared soup, noodles, fillings, fried vegetables and seasonings

5. Dip in food, as a dining accessory, you will also experience an unexpected delicacy
