Problems solved by technology

In this way, walnut oil is easier to press out rice, but the press is easy to wear, the color of the oil is too dark, and the quality of the oil is not good
More importantly, it is difficult to separate the walnut shells in the cake, so the walnut cake cannot be reused, resulting in a great waste of resources

Abstract

The invention relates to a method for preparing walnut oil and a formulated product taking walnut oil as stroma. The method mainly comprises the steps: crushing shell, sorting, squeezing, filtering I, winterization and filtering II; wherein, the squeezing process comprises: cakes made of walnut meat are evenly mixed with the walnut meat according to the mass ratio of 1:0.5-5, the mixture is squeezed to obtain crude oil and secondary cakes; the obtained secondary cakes are continuously recycled for use in the squeezing process when oil is made the next time, and then the obtained third-time cakes are used in the next time of oil making process; the process is repeatedly carried out in this way, so that the aim of recycling the cakes can be achieved; every 100g of the formulated product contains 79-99.8g of walnut oil, 0.1-20g of flax seed oil, 0.01-0.5g of DHA, 0.01-1.0g of AA, 300-900mug of vitamin A (based on retinol equivalent), 5-10mug of vitamin D and 4-7mg of vitamin E (based on da tocopherol). The method saves energy and reduces the production cost.

Description

technical field [0001] The invention relates to a processing method of edible oil and a formula product based on it. Background technique [0002] Walnut oil is rich in unsaturated fatty acids, the content of linoleic acid and α-linolenic acid are about 70% and 10% respectively. Among them, the ratio of omega-6 and omega-3 series polyunsaturated fatty acids is 6-7:1, which is in line with the recommendations of the United Nations Food and Agriculture Organization (FAO) and the World Health Organization (WHO) omega-6:omega-3 = 5-10:1, It is an edible oil with reasonable fatty acid content and ratio. Walnut oil also contains a variety of vitamins and mineral elements, and is rich in physiologically active substances, which have special effects in cell repair, anti-inflammatory, anti-virus, and anti-thrombosis. Walnut oil has been proved to be non-toxic and non-carcinogenic by animal toxicity, mutagenic and teratogenic experiments, and it is suitable for long-term consumption...
